Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we have our annual updates episode, and we’ll also learn about a mystery animal called the lava bear! As usual, a reminder that I don’t try to update everything we’ve ever talked about. That would be impossible. I just pick new information that is especially interesting.

After our episode about animals and ultraviolet light, I got a great email from Kelsey and Torin with some information I didn’t know. I got permission to quote the email, which I think you’ll find really interesting too:

“You said humans can’t see UV light, which is true, however humans can detect UV light via neuropsin (a non-visual photoreceptor in the retina). These detectors allow the body to be signaled that it’s time to do things like make sex-steroid hormones, neurotransmitters, etc. (Spending too much time indoors results in non-optimal hormone levels, lowered neurotransmitter production, etc.)

“Humans also have melanopsin detectors in the retina and skin. Melanopsin detectors respond to blue light. Artificial light (LEDs, flourescents, etc) after dark entering the eye or shining on the skin is sensed by these proteins as mid-day daylight. This results in an immediate drop in melatonin production when it should be increasing getting closer to bedtime.”

And that’s why you shouldn’t look at your phone at night, which I am super bad about doing.

Our first update is related to ultraviolet light. A study published in October of 2023 examined hundreds of mammals to see if any part of their bodies glowed in ultraviolet light, called fluorescence. More than 125 of them did! It was more common in nocturnal animals that lived on land or in trees, and light-colored fur and skin was more likely to fluoresce than darker fur or skin. The white stripes of a mountain zebra, for example, fluoresce while the black stripes don’t.

The study was only carried out on animals that were already dead, many of them taxidermied. To rule out that the fluorescence had something to do with chemicals used in taxidermy, they also tested specimens that had been flash-frozen after dying, and the results were the same. The study concluded that ultraviolet fluorescence is actually really common in mammals, we just didn’t know because we can’t see it. The glow is typically faint and may appear pink, green, or blue. Some other animals that fluoresce include bats, cats, flying squirrels, wombats, koalas, Tasmanian devils, polar bears, armadillos, red foxes, and even the dwarf spinner dolphin.

In episode 20 we talked about Delcourt’s giant gecko, which is only known from a single museum specimen donated in the 19th century. In 1979 a herpetologist named Alain Delcourt, working in the Marseilles Natural History Museum in France, noticed a big taxidermied lizard in storage and wondered what it was. It wasn’t labeled and he didn’t recognize it, surprising since it was the biggest gecko he’d ever seen—two feet long, or about 60 cm. He sent photos to several reptile experts and they didn’t know what it was either. Finally the specimen was examined and in 1986 it was described as a new species.

No one knew anything about the stuffed specimen, including where it was caught. At first researchers thought it might be from New Caledonia since a lot of the museum’s other specimens were collected from the Pacific Islands. None of the specimens donated between 1833 and 1869 had any documentation, so it seemed probable the giant gecko was donated during that time and probably collected not long before. More recently there was speculation that it was actually from New Zealand, since it matched Maori lore about a big lizard called the kawekaweau.

In June of 2023, Delcourt’s gecko was finally genetically tested and determined to belong to a group of geckos from New Caledonia, an archipelago of islands east of Australia. Many of its close relations are large, although not as large as it is. It’s now been placed into its own genus.

Of course, this means that Delcourt’s gecko isn’t the identity of the kawekaweau, since it isn’t very closely related to the geckos of New Zealand, but it might mean the gecko still survives in remote parts of New Caledonia. It was probably nocturnal and lived in trees, hunting birds, lizards, and other small animals.

We talked about some really big worms in episode 289, but somehow I missed the longest worm of all. It’s called the bootlace worm and is a type of ribbon worm that lives off the coast of Norway, Denmark, Sweden, and Britain, and it’s one of the longest animals alive. The longest worm we talked about in episode 289 was an African giant earthworm, and one was measured in 1967 as 21 feet long, or 6.7 meters. The bootlace worm is only 5 to 10 mm wide, but it routinely grows between 15 and 50 feet long, or 5 to 15 meters, with one dead specimen that washed ashore in Scotland in 1864 measured as over 180 feet long, or 55 meters.

When it feels threatened, the bootlace worm releases thick mucus. The mucus smells bad to humans but it’s not toxic to us or other mammals, but a recent study revealed that it contains toxins that can kill crustaceans and even some insects.

We talked about the painted lady butterfly in episode 203, which was about insect migrations. The painted lady is a small, pretty butterfly that lives throughout much of the world, even the Arctic, but not South America for some reason. Some populations stay put year-round, but some migrate long distances. One population winters in tropical Africa and travels as far as the Arctic Circle during summer, a distance of 4,500 miles, or 7,200 km, which takes six generations. The butterflies who travel back to Africa fly at high altitude, unlike monarch butterflies that fly quite low to the ground most of the time. Unlike the monarch, painted ladies don’t always migrate every year.

In October of 2013, a researcher in a small country in South America called French Guiana found some painted lady butterflies on the beach. Gerard Talavera was visiting from Spain when he noticed the butterflies, and while he recognized them immediately, he knew they weren’t found in South America. But here they were! There were maybe a few dozen of them and he noticed that they all looked pretty raggedy, as though they’d flown a long way. He captured several to examine more closely.

A genetic study determined that the butterflies weren’t from North America but belonged to the groups found in Africa and Europe. The question was how did they get to South America? Talavera teamed up with scientists from lots of different disciplines to figure out the mystery. Their findings were only published last month, in June 2024.

The butterflies most likely rode a well-known wind current called the Saharan air layer, which blows enough dust from the Sahara to South America that it has an impact on the Amazon River basin. The trip from Africa to South America would have taken the butterflies 5 to 8 days, and they would have been able to glide most of the time, thus conserving energy. Until this study, no one realized the Saharan air layer could transport insects.

We talked about the giant great ape relation Gigantopithecus in episode 348, and only a few months later a new study found that it went extinct 100,000 years earlier than scientists had thought. The study tested the age of the cave soils where Gigantopithecus teeth have been discovered, to see how old it was, and tested the teeth again too. As we talked about in episode 348, Gigantopithecus ate fruit and other plant material, and because it was so big it would have needed a lot of it. It lived in thick forests, but as the overall climate changed around 700,000 years ago, the forest environment changed too. Other great apes living in Asia at the time were able to adapt to these changes, but Gigantopithecus couldn’t find enough food to sustain its population. It went extinct between 295,000 and 215,000 years ago according to the new study, which is actually later than I had in episode 348, where I wrote that it went extinct 350,000 years ago. Where did I get my information? I do not know.

The first footprints of a terror bird were discovered recently in Argentina, dating to 8 million years ago. We talked about terror birds in episode 202. The footprints were made by a medium-sized bird that was walking across a mudflat, and the track is beautifully preserved, which allows scientists to determine lots of new information, such as how fast the bird could run, how its toes would have helped it run or catch prey, and how heavy the bird was. We don’t know what species of terror bird made the tracks, but we know it was a terror bird.

We talked about the extinction of the mammoth in episode 256, especially the last population of mammoths to survive. They lived on Wrangel Island, a mountainous island in the Arctic Ocean off the coast of western Siberia, which was cut off from the mainland about 10,000 years ago when ocean levels rose. Mammoths survived on the island until about 4,000 years ago, which is several hundred years after the Great Pyramid of Giza was built. It’s kind of weird to imagine ancient Egyptians building pyramids, and at the same time, mammoths were quietly living on Wrangel Island, and the Egyptians had no idea what mammoths were. And vice versa.

A 2017 genetic study stated that the last surviving mammoths were highly inbred and prone to multiple genetic issues as a result. But a study released in June of 2024 reevaluated the population’s genetic diversity and made a much different determination. The population did show inbreeding and low genetic diversity, but not to an extent that it would have affected the individuals’ health. The population was stable and healthy right to the end.

In that case, why did the last mammoths go extinct? Humans arrived on the island for the first time around 1700 BCE, but we don’t know if they encountered mammoths or, if they did, if they killed any. There’s no evidence either way. All we know is that whatever happened, it must have been widespread and cataclysmic to kill all several hundred of the mammoths on Wrangel Island.

We talked about the dingo in episode 232, about animals that are only semi-domesticated. That episode came out in 2021, and last year Caleb suggested we learn more about the dingo. I found a really interesting 2022 study that re-evaluated the dingo’s genome and made some interesting discoveries.

The dingo was probably brought to Australia by humans somewhere between 3,500 and 8,500 years ago, and after the thylacine was driven to extinction in the early 20th century, it became the continent’s apex predator. Genetic studies in the past have shown that it’s most closely related to the New Guinea singing dog, but the 2022 study compared the dingo’s genome to that of five modern dog breeds, the oldest known dog breed, the basenji, and the Greenland wolf.

The results show that the dingo is genetically in between wolves and dogs, an intermediary that shows us what the dog’s journey to domestication may have looked like. The study also discovered something else interesting. Domestic dogs have multiple copies of a gene that controls digestion, which allows them to eat a wide variety of foods. The dingo only has one copy of that gene, which means it can’t digest a lot of foods that other dogs can. Remember, the dingo has spent thousands of years adapting to eat the native animals of Australia. When white settlers arrived, they would kill dingoes because they thought their livestock was in danger from them. The study shows that the dingo has little to no interest in livestock because it would have trouble digesting, for instance, a lamb or calf. The animals most likely to be hurting livestock are domestic dogs that are allowed to run wild.

We’ll finish with a mystery animal called the lava bear. In the early 20th century, starting in 1917, a strange type of bear kept being seen in Oregon in the United States. Its fur was light brown like a grizzly bear’s, but otherwise it looked like a black bear—except for its size, which was very small. The largest was only about 18 inches tall at the back, or 46 cm, and it only weighed about 35 pounds, or 16 kg. That’s the size of an ordinary dog, not even a big dog. Ordinarily, a black bear can stand 3 feet tall at the back, or about 91 cm, and weighs around 175 pounds, or 79 kg, and a big male can be twice that weight and much taller.

The small bear was seen in desert, especially around old lava beds, which is where it gets its name. A shepherd shot one in 1917, thinking it was a bear cub, and when he retrieved the body he was surprised to find it was an adult. He had it taxidermied and photographs of it were published in the newspapers and a hunting magazine, which brought more hunters to the area.

People speculated that the animal might be an unknown species of bear, possibly related to the grizzly or black bear, and maybe even a new species of sun bear, a small bear native to Asia.

Over the next 17 years, many lava bears were killed by hunters and several were captured for exhibition. When scientists finally got a chance to examine one, they discovered that it was just a black bear. Its small size was due to malnutrition, since it lived in a harsh environment without a lot of food, and its light-colored fur was well within the range of fur color for an American black bear. Lava bears are still occasionally sited in the area around Fossil Lake.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This past weekend I was out of town, or to be completely honest I will have been out of town, because I’m getting this episode ready well in advance. Since July 4 was only a few days ago, or will have been only a few days ago, and July 4 is Independence Day in the United States of America, I thought it might be fun to talk about a very American bird, Washington’s eagle.

We talked about it before way back in episode 17, and I updated that information for the Beyond Bigfoot & Nessie book for its own chapter. When I was researching birds for episode 381 I revisited the topic briefly and realized it’s so interesting that I should just turn it into a full episode.

We only have two known species of eagle in North America, the bald eagle and the North American golden eagle. Both have wingspans that can reach more than 8 feet, or 2.4 meters, and both are relatively common throughout most of North America. But we might have a third eagle, or had one only a few hundred years ago. We might even have a depiction of one by the most famous bird artist in the world, James Audubon.

In February 1814, Audubon was traveling on a boat on the upper Mississippi River when he spotted a big eagle he didn’t recognize. A Canadian fur dealer who was with him said it was a rare eagle that he’d only ever seen around the Great Lakes before, called the great eagle. Audubon was familiar with bald eagles and golden eagles, but he was convinced the “great eagle” was something else.

Audubon made four more sightings over the next few years, including at close range in Kentucky where he was able to watch a pair with a nest and two babies. Two years after that he spotted an adult eagle at a farm near Henderson, Kentucky. Some pigs had just been slaughtered and the eagle was looking for scraps. Audubon shot the bird and took it to a friend who lived nearby, an experienced hunter, and both men examined the body carefully.

According to the notes Audubon made at the time, the bird was a male with a wingspan of 10.2 feet, or just over 3 meters. Since female eagles are generally larger than males, that means this 10-foot wingspan was likely on the smaller side of average for the species. It was dark brown on its upper body, a lighter cinnamon brown underneath, and had a dark bill and yellow legs.

Audubon named the bird Washington’s eagle and used the specimen as a model for a life-sized painting. Audubon was meticulous about details and size, using a double-grid method to make sure his bird paintings were exact. This was long before photography.

So we have a detailed painting and first-hand notes from James Audubon himself about an eagle that…doesn’t appear to exist.

Audubon painted a few birds that went extinct afterwards, including the ivory-billed woodpecker and the passenger pigeon, along with less well-known birds like Bachman’s warbler and the Carolina parakeet. He also made some mistakes. Many people think Washington’s eagle is another mistake and was just an immature bald eagle, which it resembles.

But here’s the problem. Audubon wasn’t always truthful. He painted some birds that he never saw but claimed he did, because another bird illustrator had painted them first. Once he claimed he went hunting with Daniel Boone in Kentucky in 1810, but at that time Boone would have been in his 70s and was living several states away.

Audubon also claimed that he discovered a little bird called Lincoln’s sparrow, but this wasn’t the case. His wife’s transcript of his diary doesn’t match up with the account that Audubon published about the discovery, but magically, when his granddaughter published her version of the diary later, Audubon’s discovery of the sparrow was in it. Historians think his granddaughter changed the diary entry to match up with Audubon’s published claim, and then she burned the original diaries. Further research into Audubon’s published writings have revealed plagiarism, false data, outright lies, and even completely fake species.

Audubon was also patriotic, as evidenced by his naming the eagle after George Washington. His journals and letters are full of praise for Washington, who died in 1799, only fifteen years before Audubon first saw the “great eagle.” There’s always a chance that Audubon wanted to name a bird after his idol, but not just any bird. It had to be majestic and bold, the largest eagle in the world! Maybe he decided to invent one.

Audubon also needed money to continue his work of painting birds, and most of the money came from English nobility. His painting and notes about a gigantic eagle made a real splash, bringing him money and fame for the rest of his life. But no evidence of the eagle’s existence has been discovered in the last 200 years. All we have are one man’s notes, a painting, and some stories of other specimens here and there. What we don’t have are the specimens, not even any feathers.

While we’re talking about one Audubon eagle mystery, let’s learn about another mystery. While Audubon was an incredible painter of birds, he wasn’t all that great at painting people. Only two of his famous bird paintings contain human figures, and one of them is his painting of the golden eagle. The other is a hunter painted in the background of the snowy egret, but Audubon didn’t paint that figure himself. He painted the bird, but hired another artist to paint the background. But this isn’t the case for the golden eagle painting, and that’s where the mystery lies. Even though it’s not technically anything to do with the bird, I know we’re all here for a good mystery too, so let’s talk about this painting.

Most of the time Audubon shot the birds he painted, which isn’t a great thing to do but which was common back then for scientists and collectors to shoot even very rare animals. Few people really understood conservation at the time. In the case of the golden eagle, though, the bird was already so rare in the early 19th century that Audubon couldn’t find one to shoot. He eventually bought one from a museum in 1833—but the bird wasn’t dead. It was injured, and Audubon was so impressed by its beauty that he almost set it free. But he needed to paint the bird, and in order to do that to his own meticulous standard, the bird had to be dead so he could really examine it in detail. So, after wrestling with his conscience, he killed the bird.

He spent the next two weeks drawing, studying, and eventually painting the bird. As soon as he finished, he reportedly had a mental breakdown. Not only had he been painting almost nonstop for years at that point, he really didn’t like killing birds. Plus, in the case of the golden eagle, instead of shooting it from a distance, he had killed it up close in person—as humanely as possible, but he still ended its life, and that bothered him.

The mystery comes from a detail in the painting’s background. The golden eagle is shown in front of a dramatic background of snowy mountains, with a dead snowshoe hare in its talons. But in a tiny detail in the lower left-hand corner, a man is shown crossing a gorge on a fallen tree trunk. Strapped onto the man’s back is a dead golden eagle.

The man is awkwardly rendered, but experts believe it’s a self-portrait of Audubon himself. Some experts believe Audubon included himself with a dead eagle, navigating a perilous climb, to indicate his emotional struggle in killing the bird. But when the painting was eventually included in Audubon’s famous book of bird illustrations, the figure was gone. The gorge with the fallen tree remains, but the little man carrying the dead bird has been painted out.

The question is why. Who made that decision, Audubon himself or the publisher? If Audubon did it, was it because he was embarrassed that he’d included a self-portrait, or was he embarrassed at the poor rendering of his figure, or did he just think it detracted from the painting, or some other reason? If the publisher did it, did he dislike the badly painted little man, or did Audubon ask him to remove the figure, or some other reason? We don’t know, and very likely we’ll never know.

While Audubon reportedly loved birds, it turns out he wasn’t a great human. Besides shooting a whole lot of birds and other animals, sometimes hundreds in a single day, and lying in published scientific papers, he “owned” enslaved people and reportedly made money selling them. (Just saying that sentence makes me so mad. You cannot own people.) In 2023, members of the National Audubon Society called for the group to change its name and drop any mention of Audubon, and when the board of directors said no, a lot of members resigned.

I came into this topic really hoping Washington’s eagle was a real bird, and believing that James Audubon was an artist who loved birds and was an honest man who made some mistakes. Now I’ve discovered that Audubon was a liar and a bad person, and that Washington’s eagle was probably just the result of one of his lies. At least we still have golden eagles, bald eagles, and lots of other amazing birds to admire!

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to learn about the link between fossils and folklore, a topic inspired by a conversation I had with Richard from North Carolina.

We know that stories about monsters were sometimes inspired by fossils, and we even have an example from episode 53. That was way back in 2018, so let’s talk about it again.

In Klagenfurt in Austria there’s a statue of a dragon, called the lindorm or lindwurm, that was erected in 1593 to commemorate a local story. The story goes that a dragon lived near the lake and on foggy days would leap out of the fog and attack people. Sometimes people could hear its roaring over the noise of the river. Finally the duke had a tower built and filled it with brave knights. They fastened a barbed chain to a collar on a bull, and when the dragon came and swallowed the bull, the chain caught in its throat and tethered it to the tower. The knights came out and killed the dragon.

The original story probably dates to around the 12th century, but it was given new life in 1335 when a skull was found in a local gravel pit. It was clearly a dragon skull and in fact it’s still on display in a local museum. The monument’s artist based the shape of the dragon’s head on the skull. In 1935 the skull was identified as that of a woolly rhinoceros.

In 1989 a folklorist proposed that the legend of the griffin was inspired by protoceratops fossils. The griffin is a mythological creature that’s been depicted in art, writing, and folklore dating back at least 5,000 years, with early variations on the monster dating back as much as 8,000 years. The griffin these days is depicted as a mixture of a lion and an eagle. It has an eagle’s head, wings, and front legs, and it often has long ears, while the rest of its body is that of a lion.

The griffin isn’t a real animal and never was. It has six limbs, for one thing, four legs and two wings, and it also has a mixture of mammal and bird traits. I can confirm that it’s a lot of fun to draw, though, and lots of great stories and books have been written about it in modern times. Ancient depictions of a griffin-like monster have been found throughout much of eastern Europe, the Middle East, the Mediterranean, northern Africa, and central Asia. Much of what we know about the griffin legend comes from ancient Greek and Roman stories, but they in turn got at least some of their stories from ancient Scythia. That’s important for the hypothesis that the griffin legend was inspired by protoceratops fossils.

Protoceratops lived between 75 and 71 million years ago and its fossils have been found in parts of China and Mongolia. It was a ceratopsian but it didn’t belong to the family Ceratopsidae, which includes Triceratops. It grew up to about 8 feet long, or 2.5 meters, with a big skull and a neck frill, but while that sounds big, it actually was on the small size for a ceratopsian. At most it would have barely stood waist-high to an average human, so while it was heavy and compact, it was probably smaller, if not lighter, than a modern lion. It ate plants and while it had teeth, it also had a beak, sort of like a turtle’s beak.

Folklorist Adrienne Mayor published a number of papers and a book in the 1990s discussing the links between protoceratops fossils and the griffin legend. The fossils are fairly common in parts of Mongolia and China, and Mayor pointed out that the beak combined with four legs would have suggested a four-footed animal with a bird’s head. She suggested that the head frill might have been interpreted as wings.

As for the Scythians, which we talked about a few minutes ago, they were a nomadic people who ruled much of west and central Asia and part of eastern Europe up to about 300 BCE. They were skilled in metalworking and loved gold, so even though they didn’t have a system of writing, we have some of their metal artifacts found by archaeologists. The Scythians were so important to the ancient world that we know a lot about them from other cultures, especially the ancient Greeks, Persians, and Assyrians.

We know the griffin appeared in Scythian mythology because it’s depicted on some decorative metal items. We also have ancient stories about griffins loving gold and either battling people to steal gold, or mining gold that people stole from them, or some other variation. Scythians had elaborate trade routes that connected Asia and Europe, and as I mentioned, they were hugely influential. I mean, we’re still telling versions of monster stories that the Scythians probably came up with originally.

Mayor suggested that the Scythians found protoceratops fossils while prospecting for gold, thought they were the bones of the monster we now call a griffin, and spread stories about them throughout Eurasia. It sounds plausible, so much so that no one really investigated the story until recently.

Just last week as this episode goes live, a new study has been published by a team of paleontologists about the griffin-protoceratops connection. They worked with historians and archaeologists to determine when and where (and if) the Scythians might have discovered protoceratops fossils.

It turns out that they probably wouldn’t have, certainly not while prospecting or mining gold. Gold has never been found anywhere near protoceratops fossils, and in fact the known gold deposits in central Asia occur hundreds of kilometers away from the fossils found so far. Not only that, it would be very rare to find more than a little bit of fossilized bone sticking out of the rock in most cases.

The spread of the griffin in art doesn’t seem to have begun in central Asia, for that matter, and even the earliest artwork doesn’t seem to be very protoceratops-like. The head isn’t huge in comparison to the body, for instance. Early griffins were commonly depicted as lions with an eagle’s head, but sometimes they were depicted as eagles with a lion’s head.

That doesn’t mean that protoceratops fossils didn’t influence griffin mythology at some point, just that it didn’t seem to happen the way Mayor claimed it did.

Another common connection between a fossil and a mythical monster is likewise just speculation. The skulls of elephants and their ancestors have a big opening in the front that looks like a giant eyesocket, but which is where the trunk was located. The eyes are much smaller and more on the sides of the head, and the skull itself does somewhat resemble a really big human skull. The Cyclops, or Cyclopes, was a giant from ancient Greek myth with one eye in the middle of its face instead of the usual two eyes. Is there really a connection between some kind of elephant skull and the Cyclops?

The connection was first suggested in 1914 by a paleontologist named Othenio Abel, who suggested that skulls from dwarf elephants had inspired the myth. Before about 500 BCE, the ancient Greeks didn’t know what elephants were, and the dwarf elephants that once lived in the area went extinct about 20,000 years ago. Sicily and Malta in particular had been home to various species of dwarf elephant for half a million years, so it’s possible that elephant remains were occasionally discovered in the area. Our griffin-protoceratops friend Adrienne Mayor agrees, but there’s no proof either way of this happening.

Stories of dragons living on Mount Pilatus in Switzerland may have been inspired by the pterosaur fossils that are frequently found in the area. In 1649 a man named Christopher Schorer reported seeing a fiery dragon fly from a cave in the side of Mount Pilatus to another mountain, although he admitted that at first he thought it was a meteor. It was probably a meteor, in fact, but he convinced himself it had to be a dragon because they were known to live on the mountain. A so-called dragon skeleton found near the mountain in 1602 had reportedly been crushed flat by rocks during an earthquake, but once science caught up with the finding, it was determined to be a fossilized pterodactyl.

In many parts of the world, especially China, fossilized bones are called dragon bones, but the dragon as a mythological creature probably came first. This is probably the case for a lot of folklore monsters and animals. The story came first, and once fossils were found in the area, they were seen as proof that the story was true.

In Patagonia in South America, there’s a Chilote legend of a monster called the camahueto. When it’s grown it lives in the ocean, but it starts out life living underground. Eventually it picks a stormy night, and it emerges from the ground and rushes toward the ocean, destroying everything in its path. Its single horn may gouge a channel in the ground for a new stream to form, or it may actually live in a river as a young animal and migrate to the ocean as an adult.

An animal named Trigodon once lived in Patagonia. It was a notoungulate, part of an extinct order of hoofed animals that lived throughout South America. It was probably most closely related to rhinoceroses, horses, and other odd-toed ungulates, but it and its relatives are completely extinct with no living descendants.

Trigodon was big and heavy, probably resembling a rhinoceros in many ways, and that includes having a single short horn on its head. On its forehead, in fact, pointing straight forward. It probably wasn’t a true horn but it was a protuberance of the skull. We don’t know if it was covered with skin and hair like an ossicone, a keratin sheath like a true horn, or if it was more like a rhinoceros horn. It might have been something completely different that’s currently unknown among living animals.

Trigodon went extinct around 4 million years ago, as far as we know, but other notoungulates only went extinct around 12,000 years ago. We don’t know very much about most of them, but we do know that at least one other species had a forehead horn like Trigodon’s. It’s always possible that a rhinoceros-like one-horned animal was still alive when humans first settled Patagonia, and that it was so big and scary it inspired stories about the monster Camahueto, a bull with a single horn on its forehead.

Then again, consider the story about the camahueto. It lives underground or in rivers when it’s young, and travels to the sea only during a storm. That might just be a story used to explain earthquakes that open fissures in the ground, and other natural phenomena. Then again, it might have been inspired by fossilized trigodon skulls that are washed out of the ground by torrential rain or rivers. That’s just my theory, though, but it’s fun to speculate.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to learn about two animals, one suggested by Kai and the other suggested by Kai’s mom Emily. It’s so awesome to hear when families like to listen to the podcast together. This episode even includes a mystery animal I bet you’ve never heard of.

Let’s start with Kai’s suggestion, the greater siren. The greater siren is an amphibian, specifically a salamander, but it’s probably not the kind of salamander you’re thinking of. For one thing, it can grow over three feet long, or about a meter, which is pretty darn big for a salamander. It’s dark green or gray in color with tiny yellow or green speckles, and while it has short front legs, those are the only legs it has or needs. It also has external gills which it keeps throughout its life, unlike most salamanders who lose their external gills when they metamorphose into adults.

The greater siren lives primarily in Florida, but it’s also found in coastal wetlands throughout much of the southeastern United States. It’s mostly nocturnal and during the day it hides among water plants or under rocks, and will even burrow into the mud. At night it comes out to find food, which includes crayfish and other crustaceans, insects and spiders, little fish, other amphibians, snails, and even algae. It swallows its food whole, even snails and other mollusks. It poops out the shells and other undigestible pieces.

The grater siren’s body is long but thin, sort of like an eel, with a rounded tail that’s slightly flattened to help it swim. While it does spend its whole life in the water, it has small lungs that allow it to breathe air if it needs to. It can wriggle above ground for short distances if it needs to find a new pond or river, and sometimes it will sun itself on shore. In drought conditions when its water dries up, the greater siren will burrow into the mud and secrete mucus that mixes with dead skin cells to form a sort of cocoon. The cocoon covers everything but the siren’s mouth, so it can still breathe. Then it enters a state of torpor called aestivation, and it can stay in its mud cocoon for a long time, possibly as much as five years, and still be fine once the water returns. It does lose a lot of its body fat and its gills wither away, but it regenerates them quickly once it has water, and will gain weight quickly too once it has food.

In early spring, the female siren lays her eggs in shallow water. The male fertilizes them and takes care of them for the next two months, when they hatch into little bitty sirens that go off on their own right away.

The greater siren has tiny eyes and probably doesn’t see very well. It has a good sense of smell instead, and it can also sense movement and vibrations around it with its lateral line system. This is an organ found in many fish and a lot of larval amphibians, although the greater siren retains it throughout its life. It allows the animal to sense the movement of water in extremely fine detail. The greater siren can probably also sense electrical impulses, which is something that all animals generate when they use their muscles.

If there’s a greater siren, you may be thinking, there must be a lesser siren too. There is, and it’s very similar to the greater siren, just not as big. It only grows about two feet long at most, or 61 cm.

Kai mentioned that the greater siren looks a lot like the axolotl, a critically endangered salamander found only in Mexico. I checked to see if the two salamanders were closely related and was actually surprised to find that they’re not. They’re both salamanders and therefore share the same order, but that’s all. The greater siren and its close relations do share one important trait with the axolotl, though, which is neotony. Neotony is when an adult organism retains juvenile traits, which in the case of the salamander means it retains gills and lives underwater as an adult.

Next, Emily wanted to learn more about a bird called the anhinga. It’s sometimes called the snakebird because it has a long, serpentine neck. But before we learn about the anhinga, let’s learn about a mystery animal from Kentucky. I promise this will make sense in a minute.

In 1993 a man named Barton Nunnelly and his wife were sitting in their back yard in Stanley County, Kentucky. It was a nice day and their house was close to the Ohio River, so as they often did they just relaxed and watched the river. On this particular day, they both noticed a strange animal in the water. It was snake-like with a bill similar to a duck’s, but it obviously wasn’t a duck. It swam with its head and neck above the water, but its body was never visible. It frequently sank into the water, then surfaced elsewhere. The couple watched the animal for half an hour before it disappeared downstream.

For most people, that sighting would just be an interesting story to tell at parties, but Barton Nunnelly was a cryptozoologist. That’s someone who likes to investigate mystery animals, and while it’s a great word, it’s not an official branch of science. Zoologists, biologists, and other scientists study mystery animals all the time as part of their jobs. Nunnelly investigated—and in fact still does investigate, since he’s alive and well—mystery animals that are a lot more mystery than animal, like Bigfoot. He wrote about his sighting of what he thought might be a young freshwater sea serpent in his book Mysterious Kentucky.

Now, with Nunnelly’s sighting in mind, let’s return to the anhinga and learn a little more about this unusual bird. It can grow almost three feet in length, or about 90 cm, with a nearly four-foot wingspan, or 115 cm. A lot of its body length is due to the long neck. The male is black all over with a white tail-tip, while the female looks similar but has a brown head and neck. It looks similar to the double-crested cormorant, a close relation, but it has a longer, sharper bill. It lives throughout much of South and Central America, and is also common around the Gulf of Mexico and parts of the southeastern United States. In North America it usually stays near the coast or around wetlands, but sometimes it’s found farther inland, especially along rivers.

The most interesting feature of the anhinga is the way it hunts. It has big webbed feet and swims extremely well, and it hunts fish, frogs, and other small animals underwater. Unlike other water birds, which have water-repellent oils coating their feathers, as soon as the anhinga gets in the water, its feathers get all wet. This causes it to lose buoyancy and sink, but that’s just fine with the anhinga. It also has dense bones compared to most birds, which helps it stay underwater. The bird swims underwater until it gets close to a fish or other prey animal. Then it stabs the animal with its sharp bill, before bringing it above water to swallow. Often it will swim with its body completely submerged but its head and neck sticking up out of the water.

One interesting fact about the anhinga is that it has no nostrils. It can only breathe through its mouth. It can hold its breath underwater for about four minutes and during that time can travel quite a distance, up to about 100 yards, or 90 meters, completely underwater. In addition to fish and frogs, it will eat crayfish, crabs, insects, water snakes, and lots of other small animals. After it’s done hunting, or if it wants a rest, it will stand in the sun with its wings spread in order to dry its feathers. Cormorants do this too for the same reason.

Now, think back to Barton Nunnelly’s sighting of a duck-billed water serpent. It sounds to me an awful lot like Nunnelly saw an anhinga hunting in the river. It’s a rare visitor that far inland, but not unheard of. Naturally, not everyone knows every single bird in the world, but I feel like if you’re going to write a book about mystery animals, you should do a little research first. But maybe that’s just me.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

We’re talking about some birds again this week, with a slightly mysterious twist. These are birds that have shown up in places where they shouldn’t be, sometimes way way far from home! Thanks to Richard from NC for inspiring this episode and suggesting one of the birds we’re going to talk about, and thanks to Pranav for suggesting we cover more out of place animals.

Last week we talked about some woodpeckers, and I said I thought there was another listener who had suggested the topic. Well, that was Alexandra! Let’s start today’s episode talking about the red-cockaded woodpecker, another bird Alexandra suggested.

The red-cockaded woodpecker is native to the coastal southeastern United States, where it lives in pine forests. It’s increasingly threatened by habitat loss since the pine forests get smaller every year, and not only does it need old-growth pine forests to survive, it also needs some of the trees to be affected by red heart fungus. The fungus softens the interior wood, which is otherwise very hard, and allows a woodpecker to excavate nesting holes in various trees that can be quite large. The female lays her eggs in the best nesting hole and she and her mate raise the babies together, helped by any of their children from previous nests who don’t have a mate of their own yet. When they don’t have babies, during the day the birds forage together, but at night they each hide in their own little nesting hole to sleep.

It’s a small bird that doesn’t migrate, which is why Beth Miller, a birder in Muskegon, Michigan, couldn’t identify it when she spotted it on July 1, 2022 in some pine trees near a golf course. She took lots of photos and a recording of its calls, which she posted in a birding group to ask for help. She knew the bird had to be a rare visitor of some kind, but when it was identified as a red-cockaded woodpecker, she and nine birder friends went back to the golf course to look for it. Unfortunately, they couldn’t find the bird again. It was the first time a red-cockaded woodpecker had ever been identified in Michigan, although individual birds do sometimes wander widely.

While bird migration isn’t fully understood, many birds use the earth’s magnetic field to find their way to new territories and back again later in the year. Humans can’t sense magnetic fields but birds can, and being able to sense Earth’s magnetic field helps birds navigate even at night or during weather that keeps them from being able to see landmarks.

But sometimes birds get lost, especially young birds who have never migrated before or a bird that gets caught in storm winds that blow it far off course. If a bird shows up somewhere far outside of its normal range, birdwatchers refer to it as a vagrant, and some birders will travel great distances to see vagrant birds.

One interesting note is that birds navigating by the earth’s magnetic field can get confused if the magnetic field is disrupted by geomagnetic storms, including solar flares, sunspots, and coronal mass ejections. Very recently as this episode goes live, the aurora has been occasionally visible across much of the world. The aurora is caused by charged particles from the sun reaching Earth’s atmosphere, causing a colorful glow or shimmer in the night sky, and it’s usually only visible at or near the poles. This month it was visible in places far away from the poles. Fortunately, a really strong geomagnetic storm like the ones this month can actually make it easier for birds to migrate. Instead of getting a scrambled sense of the earth’s magnetic field, a strong geomagnetic storm can temporarily knock out a bird’s ability to sense the magnetic field at all, and that means it uses landmarks, the position of the stars and sun, and other methods to find its way.

Sometimes a bird just flies the wrong way, like the Steller’s sea eagle that showed up in Alaska at the end of August 2020. Steller’s sea eagle is native to the coast of northeastern Asia and is increasingly threatened due to habitat loss, pollution, climate change, poaching, and overfishing, a real problem if you’re an eagle that eats a whole lot of fish. Only about 4,000 of the birds remain in the wild. It’s a huge eagle, one of the biggest in the world, with a big female having a wingspan over 8 feet across, or almost 2.5 meters. Some unverified reports indicate birds with a wingspan over 9 feet across, or 2.8 meters. It has a huge yellow bill and feet, and is black and white in color. It’s related to the bald eagle but is larger and heavier, and its head is black instead of white.

To an eagle as big as Steller’s sea eagle, the distance between the eastern coast of Russia and the western coast of Alaska is very small, so it’s not all that unusual for birders to see one in Alaska. The difference in 2020 is that the bird was far inland, not on the coast. Then, several months later, a Steller’s sea eagle was reported in Texas. Texas! Very far away from Alaska and the northeastern Asian coast.

No one could definitively say if the Texas bird was the same one seen in Alaska, but a few weeks before there had been a massive storm that could have blown the eagle to San Antonio. It was the first time a wild Steller’s sea eagle had been spotted in Texas.

But the bird wasn’t done traveling. In late June 2021, a ranger in eastern Canada spotted the sea eagle. It was seen by multiple birders and photographers, some of whom got pictures good enough to compare to the Alaska photos from the year before, and it was the same bird! A few months later it was spotted in Nova Scotia, Canada, and in mid-December 2021 it arrived in southern Massachusetts in the United States for a few days. By the end of 2021 it was in Maine.

Since then the eagle appears to divide its time between Maine in the northeastern United States and Newfoundland, Canada, not too far away.

Richard from NC suggested that sightings of Steller’s sea eagle might explain the mystery of Washington’s eagle. I go into detail about Washington’s eagle in the Beyond Bigfoot & Nessie book. There is a rare color morph of Steller’s sea eagle that is almost all black, which matches Audubon’s painting of Washington’s eagle, but Steller’s sea eagle always has a yellow bill, not a dark one as Audubon painted. Still, it’s a very interesting theory that matches a lot better than the theory that Washington’s eagle is just a big juvenile bald eagle.

Eagles are spectacular birds, but even an ordinary bird turns into a celebrity when it shows up somewhere far outside of its normal range. That’s what happened to a European robin at the beginning of 2019. We talked about the European robin back in episode 333. It’s a common bird throughout much of Europe and parts of Asia, but it’s only been documented in Beijing, China three times. The third time was when one showed up in the Beijing Zoo in 2019, at least 1,500 miles, or 2,400 km, away from its usual range. Birdwatching is an increasingly popular hobby in China, and hundreds of birders showed up at the zoo not to see the animals it has on display but to see a little robin that someone in England would barely glance at.

A few months before that, on the other side of the planet, a Mandarin duck showed up in Central Park in New York City. Birders showed up soon after to look at it. The Mandarin duck is a beautiful bird related to the wood duck native to North America, but it’s native to China and other parts of east Asia. The male has a red bill, rusty red face with white markings, and purplish feathers on his sides, while the female is softer and more muted in color. Both males and females have a purplish crest and the male also has a reddish crest on both of his wings that sticks up like a sail when his wings are folded.

In other words, the male in particular is a spectacular duck, and the duck that showed up at Central Park was a male in full breeding plumage, looking his best. Since Mandarin ducks are so attractive and increasingly threatened in the wild, many zoos and private owners keep them, and the Central Park duck did have a band on his leg that indicates he might have been an escaped bird. But no one ever claimed him and in March of 2019 he flew off for good.

Vagrant birds show up in weird places all the time, especially in spring and fall when most migratory birds are on the move. Sometimes a vagrant bird returns to the mistaken area in following years, brings its mate and offspring, and essentially founds a new migratory route. This is what scientists think has happened with several species of songbird that breed in Siberia and migrate to southeast Asia for the winter.

Richard’s pipit is a medium-sized songbird with long legs, a long tail, and a relatively long bill. It’s mainly brown and black, with lighter underparts. It looks like a stretched-out sparrow. It migrates to southern Siberia, Mongolia, and a few other parts of central Asia to nest during the summer, and flies back to India and other parts of southeast Asia to spend the winter. But a small population flies west instead of south and spends the winter in Spain, Italy, and surrounding areas instead of in India.

For a long time scientists thought the birds seen in Europe were just lost. They’re still quite rare in Europe compared to their high population in Asia. Then a team of scientists caught 81 of the birds, installed leg-bands on all of them and GPS loggers on seven of them, and released them again. The birds migrated north to breed, then returned to Europe instead of Asia to spend the winter, where some were caught again and their leg-bands recorded. So just remember that when a bird shows up where it’s not expected, it might not be as lost as people think.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to learn about some mystery bovids, or cow relations, suggested by Will and Måns, whose name I am probably mispronouncing.

We’ll start with a mystery about the musk ox, which is not otherwise a mysterious animal. Måns emailed about reading a children’s book about animals that had a picture of a musk ox in the part about the Gobi Desert. The problem is, the musk ox is native to the Arctic and was once found throughout Greenland, northern Canada, Alaska, and Siberia. So the question is, was the book wrong or are there really musk oxen in the Gobi Desert?

We’ll start by learning about the musk ox and the Gobi Desert. The musk ox can stand up to 5 feet tall at the shoulder, or 1.5 meters. It has thick, dense, shaggy fur all over, a tiny tail only about four inches long, or 10 cm, and horns that curve down close to the sides of its head and then curve up again at the ends.

The musk ox is well adapted to the cold, which isn’t a surprise since it evolved during the ice ages. Its ancestors lived alongside mammoths, woolly rhinos, and other Pleistocene megafauna. Like many cold-adapted animals, its fur consists of a thick undercoat that keeps it warm, and a much longer layer of fur that protects the softer undercoat. The undercoat is so soft and so good at keeping the animal warm in bitterly cold temperatures that people will sometimes keep musk oxen in order to gather the undercoat in spring when it starts to shed, to use for making clothing and blankets. But it’s definitely not a domesticated animal. It can be aggressive and extremely dangerous.

A warm coat isn’t the musk ox’s only cold adaptation. The hemoglobin in its blood is able to function well even when it’s cold, which isn’t the case for most mammals. It lives in small herds that gather close together in really cold weather to share body heat, and if a predator threatens the herd, the adults will form a ring around the calves, their heads facing outward. Since a musk ox is huge, heavy, and can run surprisingly fast, plus it has horns, if a wolf or other predator is butted by a musk ox it might end up fatally injured.

The main predator of the musk ox is the human, who hunted it almost to extinction by the early 20th century. It was completely extirpated in Alaska but was reintroduced there and in parts of Canada in the late 20th century. Similarly, it was reintroduced to parts of Siberia and even parts of northern Europe, although not all the European introductions were successful.

So what about the Gobi Desert? It’s nowhere near the Arctic. Not all deserts are hot. A desert just has limited rainfall, and the Gobi is a cold desert. Parts of the Gobi are grasslands and parts are sandy or rocky, and it covers a huge expanse of land in central Asia, mainly divided between northern China and southern Mongolia. Some parts of it do get limited rainfall in the summer and limited snowfall and frost in the winter, but for the most part it’s dry and therefore has limited vegetation for animals to eat.

Animals do live in the Gobi, though. The wild Bactrian camel, which has two humps, is found nowhere else in the world and is critically endangered. The Mongolian wild ass lives in parts of the Gobi, as do several species of antelope and gazelle, wild sheep, and ibex. The Gobi bear, which is the rarest bear in the world, also lives in the Gobi, along with smaller animals like hares, foxes, polecats, marmots, and various lizards, snakes, and birds. Occasionally wolves and snow leopards visit parts of the Gobi. So do humans, specifically nomadic herders who travel through parts of the desert to find food for their animals.

Of all the animals found in the Gobi, and in central Asia in general, the musk ox is not listed on any scholarly site I could find. Despite its name, it’s not actually closely related to other cattle and is instead most closely related to goats and sheep. However, a close relation of the domestic cow and its ancestors is the wild yak, the ancestor of the domestic yak. The wild yak lives mostly in the Himalayas these days but was once much more widespread, and the domestic yak is farmed by nomadic herders in the colder, more mountainous parts of the Gobi.

The yak isn’t closely related to the musk ox, but it does have a very similar-looking long, shaggy coat. Its horns point forward and up like cattle horns, but to someone who doesn’t really know much about yaks or musk ox, it would be easy to get the two confused. This seems to be what has happened in the case of the children’s book Måns read and in various non-academic websites. I think we can call this mystery solved.

Next, let’s go on to Will’s suggestion of mystery bovids. The family Bovidae includes not just the domestic cow and its relations but goats, sheep, antelopes, and many other animals with cloven hooves who chew the cud as part of the digestive process–but not deer or giraffes, and not the pronghorn even though people call it an antelope. Many bovids have horns, usually only two but sometimes four or even six, and those horns are never branched. Sometimes only the male has horns, sometimes both the male and female. Bovids don’t have incisors in the front of the upper jaw, only in the lower jaw, and instead has a tough dental pad that helps it grab plants.

One mystery bovid is a creature from Madagascar, called the habeby. It’s supposed to look like a big white sheep with brown or black spots. It has cloven hooves and droopy ears but not horns, and it’s supposed to be nocturnal and never seen in the daytime. Its eyes are very large and staring. It’s shy and fortunately not dangerous. Bovids are almost always diurnal, so a nocturnal bovid would be quite unusual.

Since sheep and other bovids aren’t native to Madagascar, it’s much more likely that the habeby is a type of large lemur that looks enough like a sheep at a distance that people thought it was a sheep. Either it’s extinct now or it lives in such remote areas that it’s never seen anymore.

Another Madagascar mystery animal is called the songòmby, which either looks like a wild ox or a horse depending on the story. Like the habeby it has floppy ears, a spotted coat, and hooves. Some stories say it has a single horn, some stories say it has a pair of horns, and other stories say it has no horns at all. It lives in mountainous areas and can run incredibly fast uphill, but is much slower downhill because its long ears flop over its eyes and it has trouble seeing where it’s going. This is fortunate, because it’s also supposed to eat people.

One clue to the songòmby’s possible real identity comes from some stories that state it always looks backwards over its back, and is only ever seen from the side. This is reminiscent of how the Chinese kilin is often represented, and also explains why the songòmby has a varying number of horns and looks like a cow or horse but is supposed to eat people. The kilin is often depicted as having both hooves and fangs, and may have a single horn, a pair of horns, or no horns at all. Arab traders began stopping in Madagascar around a thousand years ago and would have brought Chinese goods, including some items decorated with kilins. It’s possible that the kilin artwork inspired the story of the songòmby, but it’s also so similar to the habeby in some ways that details of that animal may have been incorporated into the story of the songòmby, or vice versa.

Way back in episode 100 we talked briefly about an animal called the kouprey. It’s a wild ox native to southeast Asia, sometimes called the forest ox. It can stand over six feet tall at the shoulder, or two meters, and while bulls are dark brown, cows and calves are a lighter brownish-gray. Both have white lower legs with a dark stripe down the front of the front legs. The bull’s horns look like those of a domestic cow or wild yak, but are extremely large and curve forward, but the cow’s horns grow up and back, more like an antelope’s horns. As a bull ages, the tips of his horns start to fray and end up looking almost tassled. A bull also develops a large dewlap as he ages, which in older bulls can actually be so big it touches the ground.

By 1937, when a kouprey was sent to a zoo in Paris, the animal was probably mostly restricted to the forests of Cambodia. Before then it had been completely unknown to science, but after that, European big game hunters went to Cambodia to kill as many as possible. It was already rare and by the 1950s there were probably fewer than 500 individuals left alive. By the 1960s, there were probably no more than 100 animals left alive. The last verified sighting of one was in 1983.

Recently, some scientists have questioned whether the kouprey actually existed at all. Its description sounds a lot like another bovid, the wild banteng. A bull banteng is dark brown or black while the cows are light brown or reddish-brown. Both have white lower legs and a white patch on the rump. Some scientists started to think that either the kouprey was a misidentification of the banteng or the hybrid offspring of a banteng and a domestic cow.

A 2006 genetic study suggested that this was the case, that the kouprey was just a hybrid animal. But a follow-up study, including genetic testing of a kouprey skull that dated back to before cattle were domesticated, came to a different conclusion. The kouprey was a distinct species, not a hybrid animal. The real mystery now is whether it’s still alive or if it has gone extinct in the last 40 years.

We’ll finish with a domestic cow that’s a little bit of a mystery. A popular brand of chocolate in Europe is Milka, and since 1973 many of its advertisements have included a light purple and white cow with a bell around her neck. Well, in 2012 a calf was born in Serbia that actually looked like the Milka purple cow. It was a purple cow!

In January of 2012 a bull calf was born on a small farm in Serbia. There’s not a lot of information available about it, but it looks like it was a breed of cattle called the busa, or maybe a busa cross. The busa is mainly raised in the mountainous parts of Serbia and mostly raised as a meat animal. It’s rare these days but was once extremely popular in the area, so a lot of cattle raised in Serbia have at least some busa ancestry. The busa can be white with darker markings, or a solid color with no white or very little white. It can be red-brown, black, or gray.

In pictures, the purple calf’s mother looks to be black and white. The calf itself is white with markings that look pale blue-gray, almost lilac. The pictures aren’t very good so it’s hard to tell. The farmer was surprised when he saw the calf and called a veterinarian to make sure it was healthy, which it was. The veterinarian suggested the calf’s strange coloration was just a rare color mutation.

As it happens, a blue-gray coloration is common in a variety of busa cattle raised in Macedonia. It’s also a common coloration in other breeds of cattle. A pale version of this color can look almost like a shade of lilac. Since I can’t find a follow-up to the 2012 articles about the calf, it’s probable that as he grew up, his spots darkened to look more gray than purple. The farmer said that he would be keeping the little purple cow instead of slaughtering him to make steaks and hamburgers, so hopefully there’s still a handsome purple and white bull living his best life in the mountains of Serbia.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to learn about a mystery animal suggested by Pranav. It’s the marozi, a big cat from the mountains of Kenya.

Kenya is in east Africa, and humans have lived in what is now Kenya since humans existed. Because of this, usually when we talk about Kenya or east Africa, we’re talking about hominins, but today we’re talking about big cats.

Kenya is home to a lot of animals you think of when someone mentions the animals of Africa, like elephants and giraffes, and it’s also home to three big cats: lions, leopards, and cheetahs. The lion is generally a tawny brown color although different individuals and populations can be various shades of brown or gray. A lion cub is born with dark spots, and as it grows the spots fade. Sometimes a young adult lion will still have some spots, especially on its legs and belly, but in general an adult lion has no spots at all. In comparison, both the leopard and the cheetah are famous for their spots.

The lion prefers to live in savannas and open woodlands. These days it’s only found in a few parts of India, along with various places in sub-Saharan Africa. This just means south of the Sahara desert. In the past, though, the lion had a much larger range. It lived throughout most of Africa, the Middle East, southern Asia, and even southern Europe. Overhunting drove it to extinction in many parts of its historic range, which is called extirpation. I’ve used the term before but it specifically means that an animal has been driven to extinction in one area where it once lived, but it isn’t extinct in other areas. Some subspecies of lion have gone extinct, and the lions who remain are vulnerable to habitat loss, poaching, and many other factors. Just because lions are common in zoos doesn’t mean lions in the wild are doing fine.

The same is true of the cheetah, which has an even smaller range than the lion these days but which was once common throughout Africa and the Middle East along with a lot of southern Asia and Europe. We talked about the cheetah in episode 145. It’s actually not closely related to the lion or the leopard, and in fact genetic testing reveals that it’s most closely related to the puma of North America.

The leopard, on the other hand, is a very close relation to the lion. Both belong to the same genus, Panthera, which also includes tigers, jaguars, and snow leopards, but the lion and leopard are the closest cousins. While it’s also vulnerable to habitat loss, poaching, and other factors, it’s more widespread than the lion and cheetah. It lives throughout much of sub-Saharan Africa, Asia–especially India–and even parts of eastern Russia, and in the past it was even more widespread. It prefers forests where its spots help it blend in with dappled sun and shade.

So, the lion, the leopard, and the cheetah all live in Kenya, but there’s another big cat that’s supposed to live there too. It’s called the marozi, also sometimes called the spotted lion.

Stories of lions that have spots like a leopard go back for centuries among the local people. The spotted lion is supposed to be small and the male either has no mane or only a small one. It’s supposed to live in the mountains and is solitary instead of living in family groups like ordinary lions. In fact, “marozi” supposedly means “solitary lion” in the local language. Instead of living in open grasslands, it lives in thick forest where a spotted coat and smaller body size would be useful, allowing it to maneuver through the trees more easily while not being seen.

It wasn’t until the colonial era in the late 19th and early 20th centuries that Europeans became aware of the marozi. The first known sighting of a spotted lion by a European occurred in 1903, when a British soldier reported seeing more than one in the mountains of Kenya. He said the lions were darker in color than an ordinary lion, with leopard-like rosette markings. In 1924, a game warden reported killing a spotted lioness and her cubs, with the lioness having just as many spots as the babies.

In 1931 a farmer shot two small spotted lions in the mountains. He said they were fully grown despite their small size, but they had even more spots than lion cubs do. One was a male and he had a sparse, short mane. The farmer kept the male’s skin, which eventually made its way to the Natural History Museum in London, possibly with the lion’s skull too, although it’s not clear if the skull actually belongs to the same animal. As far as I could find out, no one has tried to test the skin and skull genetically.

Other people, including hunters and game wardens, reported seeing spotted lions in high elevations where ordinary lions didn’t live, with stories continuing through at least the 1960s. Similar stories of a spotted lion have been collected from mountains in other parts of east and central Africa, including Ethiopia, Rwanda, Uganda, and Cameroon, where it has different local names. But so far we don’t have any photographs or a specimen.

There are a few hypotheses about what the marozi might be. One suggestion is that it’s actually a hybrid of a leopard and a lion. Because leopards and lions are so closely related, they can interbreed and produce offspring, although as far as we know this has only happened in captivity. In the wild, lions are actually aggressive towards leopards. A lion will steal a leopard’s food and will sometimes even kill leopards, and as a result leopards try to avoid lions. Since leopards prefer thick forest and lions prefer open forest or grasslands, they don’t cross paths all that often anyway.

In the late 1950s into the early 1960s, a zoo in Japan kept a male leopard and a female lion in the same enclosure to see if they would mate. They did, and eventually they had two litters together. The cubs were larger and heavier than leopards but not as big as lions, and while they generally looked like lions they had leopard spots. The males had small manes.

This sounds a lot like reports of the marozi, but again, in the wild lions and leopards mostly avoid each other. The only time a lion and a leopard would consider each other potential mates instead of potential trouble is when they’re put together artificially as in the Japanese zoo. Even if an occasional leopard and lion do sometimes breed in the wild, it wouldn’t happen often enough to cause all the sightings documented about the marozi. Besides, the marozi is only reported from the mountains, where lions don’t live.

Another hypothesis is that there’s a population of ordinary lions that have moved into the mountains to escape factors like habitat loss, poaching, and a decline in prey animals, and that people occasionally see a young adult lion that hasn’t completely lost its cub spots. This isn’t too likely either since stories of the marozi go back to long before these modern pressures on lion populations.

There might very well be an unknown, very rare species or subspecies of lion that has always lived in the mountains in parts of east and central Africa, and that it does actually have spots as an adult. If this is the case, hopefully it’s safe in its mountain habitat from the pressures faced by ordinary lions. Let’s hope also that it comes to the attention of scientists soon so it can be studied and protected.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we have a suggestion from Chuck, who wanted to learn about a small hoofed animal that I don’t think we’ve ever covered before, the muntjac. It’s a deer, but it’s a very weird deer.

In fact, it’s not just one deer, it’s at least 12 different species that are native to parts of south and southeast Asia, although it used to have a much broader range. Muntjac fossils have been found throughout Europe in particular. It prefers thick forests with lots of water around. Most species live in tropical or subtropical areas, although it can tolerate colder temperatures. It eats leaves, grass, fruit, seeds, and other plant parts, and it will also sometimes eat bird eggs and small animals when it finds them. It will even sometimes eat carrion.

The typical muntjac is small, barely larger than a fox. The largest species, the giant muntjac, stands a little over two and a half feet tall at the shoulder, or 80 cm, while there are several species of muntjac that don’t grow taller than 15 inches high, or 40 cm. It’s brown or reddish-brown, sometimes with darker or lighter markings depending on species. The muntjac appears hump-backed in shape like a rabbit, since instead of having a mostly level back, its back slopes upward from the shoulders to the rump. Its tail is very short and males grow short antlers that either have no branches or only one branch. Males also have a single pair of sharp, curved fangs that grow down from the upper jaw, more properly called tusks.

The muntjac is usually a solitary animal, with each individual defending a small territory. Both males and females have a large gland near the eye that secretes an oily substance with a strong smell. It also has another pair of scent glands on the forehead. The muntjac rubs its face on the ground to mark the edges of its territory with scent. It can even flare its scent glands open to communicate with other muntjacs by smell more effectively.

Unlike many deer species, the muntjac doesn’t have a particular mating season. Females, called does, can come into season any time of the year, so males are always ready to fight with other males for a doe’s attention. The male loses and regrows his antlers yearly, but mainly he only uses them to push an opponent over. He does the real fighting with his fangs.

There are other types of hoofed animals with fangs. We talked about the musk deer and the chevrotain in episode 116, but even though the chevrotain in particular looks a lot like the muntjac, it’s not closely related to it at all. Neither is the musk deer. In fact, neither the musk deer nor the chevrotain are actually deer, and they’re not even closely related to each other.

The southern red muntjac is one of the smallest species of muntjac known and is fairly common throughout much of southeast Asia, although we don’t know much about it. One thing we do know is that it has the smallest number of chromosomes of any mammal ever studied. Males have 7 diploid chromosomes and females only have 6. In comparison, the common Reeve’s muntjac has 46 diploid chromosomes. Scientists have no idea why there’s so much difference in chromosome count between species, but it works for the muntjac.

Many species of muntjac are common and are doing just fine, but others are endangered due to habitat loss, hunting, and the other usual factors we talk about a lot. But the muntjac is small, solitary, and very shy, so there are also species that are probably still waiting to be discovered.

The giant muntjac, also called the large-antlered muntjac, was only discovered in 1994 from a skull found in Vietnam. Scientists were eager to learn more about the animal, especially whether it was still alive or had gone extinct. They talked to hunters and other local people in Vietnam and Laos, and set up camera traps, and went on expeditions searching for it. The hunters said it was still around but the scientists just couldn’t find any. It wasn’t until 1997 that a camera trap took a few pictures of one near a newly constructed dam, which gave everyone hope that this animal could be saved from possible extinction.

Scientists had been searching for the giant muntjac for so long, and had only finally gotten a photograph after 13 years of trying, that they figured it would be an even longer time before they learned more about it. But then, suddenly, only four months after the first pictures of the giant muntjac were captured, a team of conservationists working to relocate animals from the flood area of the new dam ended up capturing 38 of the deer.

When a new dam is constructed across a river or other waterway, it doesn’t flood right away. It takes a long time for the water to back up behind the dam and turn into a lake or large pond, sometimes several years depending on the size of the dam and the waterway. There’s time to relocate animals to higher ground so they’ll be safe, and that’s exactly what Ulrike Streicher and her team were doing in 2007. Not only that, they made sure to transport the animals to a protected area where they’d be safer from hunters. Before they released the giant muntjacs, they had the opportunity to study them and fit some of them with radio collars so the scientists could track where they went. It turned out that the muntjacs settled into their new home just fine, so although the giant muntjac is still classified as critically endangered, at least we know that one small population is doing well.

Another muntjac search involves a camera trap in Vietnam and Laos too, but it’s still an ongoing mystery. The story actually starts back in 1929 when a dead muntjac was sent to the Field Museum in Chicago. The scientists at the museum couldn’t identify it as any known species of muntjac, so they described it in 1932 as Muntiacus rooseveltorum, also called Roosevelt’s muntjac. Modern genetic testing of the specimen determined that it’s a subspecies of Fea’s muntjac that lives in a small area of southern Myanmar and Thailand. Fea’s muntjac itself is so rare and so little known that we don’t even know if it’s extinct or not. As for Roosevelt’s muntjac, no one had seen it since the 1929 specimen was killed and it was presumed extinct.

Then, starting in 2014, a team of scientists conducted surveys in parts of the Annamites, a mountain range along the Vietnam/Laos border. Over the next five or six years, camera traps recorded every animal that passed by them in various remote locations. In addition to lots of animals the scientists expected to see, they found three animals that were either extremely rare or thought extinct. One of these was the Annamite striped rabbit we talked about in episode 254, but the other two were muntjacs.

One of the muntjacs captured on camera was identified as Roosevelt’s muntjac while the other was identified as the Annamite muntjac, a species that was only identified in 1997. The problem is that we only have pictures of the animals, and only a single specimen of Roosevelt’s muntjac to compare the pictures to. Scientists disagree as to whether Roosevelt’s muntjac is for sure still alive and well in the Annamite mountains, or whether the pictures are of a totally different species of muntjac. At least the pictures were taken in a nature reserve, so we know the muntjacs should be safe.

Muntjacs are such strange, attractive animals that rich people used to keep them as pets to show off. Sometimes they would escape into the wild, or were even released on purpose, and that’s why Japan, England, Wales, Belgium, the Netherlands, and Ireland all have invasive populations of Reeve’s muntjac. Reeve’s muntjac is common in southeastern China and Taiwan and only grows a little over a foot high at the shoulder, or maybe half a meter. The male has stubby little antlers and long tusks, so that his tusks are almost as long as his antlers. Cute as the animals are, they’re also bad for the local ecosystems, since they reproduce quickly and eat food that native animals need.

Rumors have circulated for a few decades now of another possible mystery muntjac, usually referred to as the quang khem. Supposedly it’s a large muntjac with unbranched antlers that lives in remote areas of Vietnam. So far it hasn’t been discovered, if it exists at all, but there’s definitely a chance that it’s yet another muntjac that’s just waiting to be spotted by scientists or their camera traps.

The muntjac is sometimes called the barking deer because of its alarm call. This is what a muntjac sounds like:

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to look at an animal suggested by Hannah a long time ago. Hannah suggested we talk about sheep, and I can’t even tell you how many times I almost did this episode but decided to push it back just a little longer. Finally, though, we have the sheep episode we’ve all been waiting for! We’re also going to learn about a strange animal called sivatherium and a mystery surrounding when it went extinct.

The sheep has cloven hooves and is a ruminant related to goats and cattle. It mostly eats grass, and it chews its cud to further break down the plants it eats. It’s one of the oldest domesticated animals in the world, with some experts estimating that it was first domesticated over 13,000 years ago. Mammoths still roamed the earth then. Sheep are especially useful to humans because not only can you eat them, they produce wool.

Wool has incredible insulating properties, as you’ll know if you’ve ever worn a wool sweater in the snow. Even if it gets wet, you stay nice and warm. Even better, you don’t have to kill the sheep to get the wool. The sheep just gets a haircut every year to cut its wool short. Wild sheep don’t grow a lot of wool, though. They mostly have hair like goats. Humans didn’t start selecting for domestic sheep that produced wool until around 8,000 years ago.

Like other animals that were domesticated a very long time ago, including dogs and horses, we’re not sure what the direct ancestor of the domestic sheep is. It seems to be most closely related to the mouflon, which is native to parts of the middle east. The mouflon is reddish-brown with darker and lighter markings and it looks a lot like a goat. Other species of wild sheep live in various parts of the world but aren’t as closely related to the domestic sheep. The bighorn and Dall sheep of western North America are closely related to the snow sheep of eastern Asia and Siberia. The ancestors of all three species spread from eastern Asia into North America during the Pleistocene when sea levels were low and Asia and North America were connected by the land bridge Beringia.

The male sheep is called a ram and grows horns that curl in a spiral pattern, while the female sheep is called a ewe. Some ewes have small horns, some don’t. This is the case for both wild and domestic sheep. Sheep use their horns as defensive weapons, butting potential predators who get too close, and they also butt each other. Rams in particular fight each other to establish dominance, although ewes do too.

But some breeds of domestic sheep are what is called polycerate, which means multi-horned. That means a sheep may have more than two horns, typically up to six. Many years ago I kept a few Jacob sheep, which are a polycerate breed, and in a Patreon episode from 2018 I went into really too much detail about this particular breed of sheep. I will cut that short here.

The Jacob is a hardy, small sheep with tough hooves, and it’s white with black spots. Ideally, a Jacob sheep will have four or six well-balanced horns. In a six-horned sheep, the upper pair branch upward, the middle pair curl like an ordinary ram’s horns, and the lower pair branch downwards. Sometimes a sheep will have three or five horns, or will start out with four horns but as they grow, two will merge so it looks like they have a single horn on one side. Sometimes a ram’s horns will grow so large that the blood supply is choked off for the lower pair, which will die and stop growing. Breeding a pair of six-horned Jacob sheep doesn’t guarantee that the babies will have more than two horns, though. It’s still a recessive trait.

Sheep, goats, cattle, and some antelopes are all bovids. Polyceratism appears to be a bovid trait. It’s caused by a mutation where the horn core divides during the animal’s development.

Occasionally, a sheep of non-polycerate breed, or a goat, or even a cow, is born with multiple horns. The blue wildebeest is also occasionally born with multiple horns. Sometimes an animal grows a lot of horns, like eight, but usually it’s three, four, five, or six.

Another animal with more than two horns is the four-horned antelope that lives in India and Nepal. Its horns are quite small, just a pair of tiny points on the forehead with a pair of longer points behind them. The antelope itself is also small, not much more than two feet tall at the shoulder, or 60 cm. Its coat is reddish or yellowish-brown with white underparts, and a black stripe down the front of the legs. The longer horns grow up to about five inches long, or 12 cm, but the front horns are no longer than two inches, or five cm.

The four-horned antelope is shy and solitary, and lives in open forests near water. Since it’s so small, it frequently hides in tall grasses. Sometimes a four-horned antelope’s front two horns are just bumps covered with fur, which makes them look like ossicones although they’re still actually horns.

That brings us to the other group of animals with multiple horns, although they’re not actually horns. I mentioned ossicones in the tallest animals episode, about giraffes. They’re made of ossified cartilage instead of bone, and are covered in skin and fur instead of a keratin sheath. Antlers are actually very similar to ossicones in many ways. A deer’s antlers grow from a base that is similar to an ossicone, and as they grow, the antlers are covered with tissue called velvet that later dries and is scraped off by the deer to show off the bony antlers. Unlike horns, which are always unbranched, the ossicones of some extinct animals can look like antlers.

We talked about sivatherium in episode 256, about mammoths. It was an ancestor of modern giraffes that lived in Africa and India around a million years ago. It stood around 7 feet tall at the shoulder, or just over two meters, but had a relatively long neck that made it almost 10 feet tall in total, or about three meters. It had two pairs of ossicones, one pair over its eyes and another between its ears. Like the four-horned antelope, the front pair were smaller than the rear pair, but the rear pair was broad and had a single branch.

Sivatherium was once believed to be closely related to elephants, and reconstructions of it often made it look like a moose with a short trunk. But modern understanding of its anatomy suggests it looked like a heavily built giraffe with shorter legs and neck, sort of like the giraffe’s closest living relative, the okapi.

One interesting thing about Sivatherium is how recently it may have been alive. Some researchers think it may have been around only 8,000 years ago. There’s rock art in India and the Sahara that does seem to show a long-necked animal with horns that isn’t a giraffe. The art has been dated to around 15,000 years ago. But the big controversy is a figurine discovered in 1928.

That’s when a copper rein ring was found in Iraq and dated to about 2800 BCE. A rein ring was part of the harness to a four-wheeled chariot, with two holes to thread the reins through to keep them from tangling. Above the rings was a little decorative figure of an animal. This particular rein ring’s figure shows an animal with short horns above the eyes and branching horn-like structures farther back, between the ears. When it was originally discovered, scientists thought the figure represented a type of fallow deer found in the area, with the ends of the antlers broken off. But one researcher, Edwin Colbert, pointed out that no deer known has four antlers and the figure clearly has two little bumps over its eyes that are separate from the branched antler or horn-like structures farther back. In 1936 he published his conclusion that the animal wasn’t a deer at all but sivatherium, and a lot of scientists agreed.

That would mean sivatherium might have been alive less than 5,000 years ago. Part of the issue is that sivatherium’s branched ossicones weren’t very big in comparison to its head, while the fallow deer’s antlers are proportionally quite large. The figurine has structures that match sivatherium’s ossicones more than a deer’s antlers. But in 1977, two little pieces of copper were found in a storage box where they’d been since the original discovery of the rein ring. The pieces fit exactly onto the ends of the figure’s horns, showing that the horns are much bigger than originally thought.

That doesn’t explain everything, though. The figure still has those extra little horns over its eyes, and while the branched horns look like deer antlers, they still don’t look like fallow deer antlers. Some researchers point out that sivatherium had a lot of variation in the size and shape of its ossicones, too.

Ultimately there’s not enough evidence either way of whether the figurine depicts a deer or sivatherium. If sivatherium did live as recently as a few thousand years ago, hopefully remains of it will be found soon. Until we know for sure, you can still be glad that the giraffe is alive, because it’s just as amazing as its extinct relation.

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

Happy Halloween! It’s time for our spookiest episode of the year! It’s rated five out of five bats on our spookiness scale. If you like scary stories on Halloween, make some cocoa and popcorn and sit back to be spooked. If you’re not really a fan of the scarier stuff, you might want to skip this one. Some people also really don’t like hearing about diseases, and that’s one of the things we’ll be discussing. We’re going to talk about a really weird cryptid called the not-deer.

Before we get started, though, we have a little bit of housekeeping, as the big podcasters call it. First, I want to reassure everyone who has sent me suggestions that I’m trying to get to them as soon as possible. I love how many people listen and want to share their enthusiasm about animals, but I do feel bad that some people have been waiting a really long time for their suggestion to make it off of the massive humongous ever-growing ideas list into an episode.

At the same time, I’ve been thinking of ways to make money off the podcast without running ads. I make Strange Animals Podcast because I love helping people learn about animals and science, and I also really value the people who are able to support the podcast through Patreon. But I do put an awful lot of work into each episode, so much that it’s basically a second job. I thought about it, and decided to make a new Patreon tier that’s a little different from the others. It’s called the terror bird tier, and when I drew the art for it I forgot that terror birds didn’t have actual teeth, but we’ll call that artistic liberty. It’s a $25 a month tier, and not only do you get access to the bonus episodes that all patrons can listen to, after three months at that tier you can message me your episode idea AND tell me what week you’d like that episode to run. I’ve limited the new tier to 25 backers, to make it fair for people who don’t have the money for that, and honestly I don’t expect to get very many people at that level at all, because that’s a lot of money, but I thought I’d give it a try.

Finally, the Beyond Bigfoot & Nessie book is still available, as are my other books, and in 2024 I’m planning to attend some conventions again to sell copies of the book. I’ll let you know where I’ll be as I find out, in case you want to come say hi. I’m also very slowly working on a sequel to the book, tentatively titled Small Mysteries, which is all about mystery animals that are really small, like frogs and insects and teeny fish. It probably won’t be ready to publish for a few years, so I’m working hard to make sure it’s got a whole lot of footnotes with references. That’s one of the things I regret not doing for Beyond Bigfoot & Nessie.

Now, with all that out of the way, on to the spookiness!

The not-deer is a cryptid, or mystery creature, that’s mostly reported from the Appalachian region of the United States. I live in the southern Appalachians near the Smoky Mountains, but I’d never heard of the not-deer until a few months ago. I subscribe to Sharon Hill’s Strange Times newsletter, and also love her Spooky Geology website where you can learn all the science behind weird events like earthquake lights. There’s a link in the show notes, but you can search for https://spookygeology.com/ to find it. Sharon Hill wrote about the not-deer in mid-2023 in her newsletter, where she said the not-deer “looks like a deer until you REALLY look and find that it’s not a deer. It displays unsettling characteristics that scare the heck out of people.”

Reports vary, but in general, the not-deer is supposed to look like an ordinary deer at first glance, but then the witness realizes it’s really weird in some ways. Some people report that the deer appears to have extra joints in its legs, a misshapen or overly large head, an overly long neck or legs that are too long or too short, eyes that are close together on the front of its head instead of on the sides of its head as is normal with hoofed animals, and so on. It might walk on its hind legs like a human, and sometimes people say the creature appears to be unusually intelligent and not afraid of people.

The not-deer became popular online around the summer of 2020, especially on TikTok, with the term not-deer apparently coined in August 2019 on Tumblr, but the idea goes back several decades at least. According to Sharon Hill, Jerry Clark, the editor of Fate Magazine, collected two accounts of not-deer in 1971, although he didn’t call them not-deer because that term wasn’t invented yet.

To give you an idea of what we’re talking about, here are three accounts from a Reddit thread. I’ve reworded the stories to make them shorter and more appropriate for a general audience, but I haven’t changed any details.

First is a 2020 report from a Redditor in northern Georgia:

“I live at the foothills of the Appalachian mountains halfway in between Chattanooga and Atlanta and sometimes my family takes trips to the mountains. One day up there me and my cousin drove around to just take in the views. At around 8pm we were headed back and were nearly at our cabin when we saw a deer on the side of the road. We slowed down but as we got close, it walked into the road. I hit the brakes and then it stood up and started walking around on its back legs. My cousin and I have been out in nature with animals our whole lives but we’d never seen anything like it. It just looked so wrong! Its joints didn’t move right and it had arms not front legs, and its upper half was like a human excluding the head.”

The next story is from a Redditor in Virginia, who at the time of their encounter was riding a motorcycle slowly along the Skyline Drive in Shenandoah National Park at night, although when they encountered the deer they stopped to get a better look.

“It was like a deer drawn by someone who had never seen a deer after someone else described it to them. It stood on the left side of the road on the mountainside, and I saw the eyes long before my headlight showed it fully. It was easily the biggest deer I’ve seen, and the lack of any antlers that time in the year suggested that it was a doe. The head was almost bovine in shape, the legs seemed too long in proportion to the body (think maned wolf proportions), and the body was extremely barrel chested.

“As soon as I crossed into the other lane, it rose up onto its hind legs. It took two jerky, unnatural steps towards the center of the lane on 2 legs and froze again, staring directly at me. It suddenly shook its head wildly like a dog with a toy, took another short step, then HOPPED on two legs several times until it disappeared into the darkness on the right side of the road.

“I turned the light towards the side of the road. On that side, there was a sheer drop off compared to the roadway, and the deer’s head was just peeking over the edge, still looking at me. The drop off was about 40 to 50 feet [that’s about 12 to 15 meters], so there’s no way it was standing at the base of the mountainside.”

Finally, in June of 2023 a Redditor wrote:

“I believe I saw a not-deer 3 weeks ago on KY 10 just outside of Lenoxburg. I was driving home to Cincinnati and decided to take the back route. It was dusk and the deer were out and moving. I looked out to my driver’s side and saw a few deer in the field, however there was one closer to the road that was…off. It had small squatty hind legs and long almost ape-like front legs and its neck was too long. The second I laid eyes on it my stomach dropped and I felt a fear I’ve never experienced before. My dogs began to tremble and whine and the feeling didn’t go away until I got back across the river to Ohio.”

The most common deer in the Appalachian Mountains is the white-tailed deer. It’s common throughout most of North and Central America down into northern South America. It’s also an invasive species in some parts of the world where people have introduced it as a game animal. Different populations and subspecies vary in size, but the Virginia subspecies found in Appalachia generally grows up to 4 feet tall at the shoulder at most, or about 1.2 meters. Males are larger than females on average. It’s crespuscular, meaning it’s most active at dawn and dusk.

In summer the white-tailed deer is reddish-brown, and in winter its coat is more gray-brown. It gets its name from the underside of its tail, which is bright white. When a deer feels threatened, it raises its tail to warn other deer to be alert, and to warn a potential predator that the deer has spotted it. Baby deer, called fawns, are born in spring and have white spots that help camouflage them in dappled sunlight and shade under trees.

The male white-tailed deer, called a buck or stag, starts growing a new set of antlers in the summer. Antlers are made of bone, but they grow faster than any other mammal bones. While they’re growing, they’re covered in a special type of highly vascularized skin called velvet. The velvet supplies nutrients and oxygen to the antler as it grows, and since the antlers grow so fast, they need a whole lot of nutrients. A deer in poor health or who can’t find enough to eat will grow small antlers, while a healthy deer who has lots to eat will grow larger antlers. Older males usually have bigger antlers than younger males too. The female deer, called a doe, is attracted to bucks with bigger antlers because she can be sure he’s healthy.

Once the antler has finished growing, it actually dies. The velvet dries up and the deer will rub his antlers on a branch or other object to help remove it. Because there are so many blood vessels in the velvet, sometimes a deer who is shedding the velvet has his antlers, head, and face splattered in blood, but he’s not hurt, just messy. Bucks use their antlers to fight each other, although they also use them to attack potential predators. Around the end of winter or early spring, the buck sheds his old antlers in preparation for growing a new set.

Many sightings of not-deer are probably due to people seeing diseased or injured deer. Two diseases that are especially hard on deer are Epizootic Hemorrhagic Disease, or EHD, and Chronic Wasting Disease, or CWD.

EHD is a virus spread by biting flies and midges, and while many species of deer can catch it, white-tailed deer are especially vulnerable to it. Humans can’t catch it, so don’t worry unless you are a deer. Symptoms of EHD include lameness, swelling of the head and neck, a lack of fear of humans, drooling and a runny nose, panting, and fever, which leads to sick deer sometimes lying down in water to cool off. Many deer who catch EHD eventually recover.

CWD is a more serious disease, sometimes called zombie deer disease. It’s related to the so-called mad cow disease found in cattle, and scrapie found in sheep and goats, and it can affect various species of deer. It’s always fatal but it can take a long time to develop, up to two years after exposure until the first symptoms. It’s caused when a protein in the animal’s nervous system is abnormally folded, a condition that spreads and causes neurodegeneration and holes in the brain. CWD is spread from animal to animal, but it can also spread through the environment in water and soil. So far the disease hasn’t been found to spread to humans.

Variations of CWD have been around for a very long time in various animals, but it was first identified in 1967 in a population of captive mule deer in Colorado. By 1981 it had spread to wild elk and it continues to spread in both wild and captive deer, although it’s still very rare. Symptoms include trembling and staggering, repetitive motions like walking in circles, grinding of teeth, drooling, confusion, and loss of fear of humans.

In addition to all this, perfectly healthy deer can have unusual behavior that isn’t witnessed by humans very often. Deer can and do stand and even walk short distances on their back legs, mostly to reach food growing up high. Does in particular will sometimes fight by standing on their hind legs and boxing each other with their front hooves. I own an amazing book called The Deer of North America by Leonard Lee Rue III, and here’s an interesting quote from that book:

“The oddest example of deer locomotion I ever heard of…was witnessed by five people. In July of 1967, the group had been out looking for deer when their trip was cut short by heavy rain. On the way home they saw two deer in a field of high weeds. Suddenly one of the deer raised both of his hind feet in the air, as if it were doing a handstand, balancing and walking on its forefeet. They thought the deer was injured and had to walk that way, but then the second deer did the same thing. Both deer walked on just their front legs for a distance of about 75 feet to where they could no longer be seen. […] We are constantly learning new things about deer.”

Leonard Lee Rue III suggested that the deer were just playing around and having fun.

Most people don’t know a whole lot about deer behavior. Most not-deer reports come from people who witnessed the creature while driving in the dark, so they didn’t get a very good look at it. Plus, as I’ve said over and over, people see what they expect to see. The not-deer has become popular online over the last few years, which means when someone is driving along and sees a deer behaving in what they think is an unusual manner, they remember the not-deer stories. Their brain automatically fills in details they can’t really see, leading to the person remembering things like a deer with human arms or six eyes.

In addition, people like telling spooky stories to scare each other. It’s probable that at least some of the scariest not-deer accounts are fiction. So if you see a deer, you don’t have to be scared. Just observe it and you might just learn something new about deer behavior. (Or something spooky will happen, in which case you have a great opportunity for a TikTok video.) Happy Halloween!
