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.

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

This week we’re going to talk about a beautiful bird that almost everyone has seen pictures of, and a lot of people might have seen in zoos and parks. It’s a suggestion by Ari, who wants to learn about the peacock!

The name peacock is technically only used for the male bird, with the female called a peahen and the birds all together referred to as peafowl. Most people just say peacocks, though, because the male peacock has such a fabulous tail that it’s what people think of when they think of peafowl. I’m happy to report that baby peafowl are called peachicks.

The peacock most people are familiar with is native to India, specifically called the Indian peafowl. It’s a surprisingly large bird, with a big male weighing more than 13 lbs, or 6 kg. Females are smaller. It’s the size of a wild turkey and in fact it’s related to the turkey, along with pheasants, partridges, and chickens. Back in episode 144 we talked about a bird called the ocellated turkey, a brightly colored turkey that lives in the Yucatan Peninsula, which is part of Mexico. The male’s tail feathers have the same type of colorful eyespots seen on a peacock’s tail.

But the peacock’s tail is way bigger than any turkey’s tail. It’s called a train and most of the time it’s folded so that it’s not in the way. A big male can grow a train that’s much longer than the rest of his body, more than five feet long, or 1.5 meters. Most of the train’s elongated feathers end in a colorful eye-spot, around 200 of them in total. The eyespot pattern really does resemble a big eye, with a dark blue spot in the middle surrounded by a ring of blue-green and a bigger ring of bronze. The bronze color is surrounded by pale green and the rest of the feather is a darker green. As far as we know, the eyespots aren’t supposed to look like eyes the way some animal markings are. A leopard or other predator doesn’t attack the tail thinking it’s a peacock’s head. It’s just a pattern.

For a long time scientists were divided as to what the peacock’s train was really used for. Not everyone thought it was for showing off for peahens. Some thought it was just for camouflage in the jungle. The main confusion was why the peacock would grow such a long, conspicuous train, which can be a hindrance to him in thick undergrowth and can attract the attention of predators. But many male birds have long, ornamental tails that may impede their mobility, such as various bird of paradise species, that are definitely meant to show off for females. This appears to be the case for the peacock too.

During mating season, male peacocks gather at what’s called a lekking site, where they hang out waiting for females. When a female approaches a male, he spreads his train into a fan and shivers it, which rattles the feathers together and also shows off the iridescent colors. The male struts around, showing off his tail, and the female may ignore him completely or take a good look at his tail. In studies where scientists snipped all the eyespots off a male’s train feathers, females never bothered to even look at the male, but since immature males don’t have eyespots, it could be the females thought the eyespot-less male was just a kid.

A 2016 study took a closer look at the shivering motion that the male produces during displays. Not only does the sound interest the female, the study discovered that the eyespots are locked together with microscopic hooks that help them stay still while the remainder of any particular feather moves, since it isn’t locked with other feathers. This makes it look like the eyespots are floating against a shimmery green background. Who wouldn’t love watching that? The brighter the eyespot’s iridescence, the more attractive the male is to females.

The rest of the Indian peacock is bright too. His back and most of his body is bronze, while his long neck is a brilliant green-blue. He has white markings on his face and a crest growing from the back of his head. The crest consists of a bundle of mostly bare feather shafts, with a little tuft of blue-green at the end. The female has a similar crest but it’s brown in color along with most of the rest of her feathers, although she does have some metallic green on her neck. She doesn’t have a long train, but she will sometimes spread her tail feathers and rattle them to communicate warnings to other peafowl. A 2018 study learned that the crests of both male and female peafowl are sensitive to vibrations, specifically to the sound frequencies produced by tail rattling.

Peafowl eat plant materials like seeds, fruit, and flower buds, but they also eat a lot of worms, insects, frogs, and other small animals, including small snakes. Because they’re so beautiful and do well in captivity, lots of zoos and parks keep peacocks. They’ve even been selectively bred to produce different colors, including a white peacock and a mostly black peacock.

Ari specifically mentioned hearing that peacocks cry happy tears. Crying tears as a result of emotions, whether happy or sad, is very specific to humans, and scientists aren’t sure why we do it. It seems to be a visual signal to other humans that the person crying needs help or support in some way. Other animals sometimes have weepy eyes, but that’s due to simple eye discharge, not emotions.

The idea that peacocks cry tears dates back many centuries. Medieval bestiaries published in Europe said that the peacock was vain of his beauty and strutted around proudly, but whenever he noticed his ugly feet he would cry. Similar proverbs date back at least several thousand years from ancient Rome and India. Some proverbs say that the peacock tries to hide his feet and that’s why he doesn’t fly very often, or that he cries first thing every morning when he first wakes up, either because he sees his feet and thinks they’re ugly, or because he’s worried he’s lost his beautiful feathers overnight. Some proverbs say that when the peacock cries at his ugly feet, the peahen will swallow one of his tears and that’s how her eggs are fertilized instead of in the usual way.

These stories are interesting, but they don’t have any basis in fact. The peacock doesn’t care what his feet look like because he’s a bird, not a human. Anyway, he has big, handsome feet that let him walk around as much as he wants. The peacock also doesn’t actually cry tears, whether happy or sad.

What he does do, though, is make a wailing noise that can sound like someone crying. It sounds like this:

[peacock sound]

Most of the time it’s only the male bird that makes these calls, as a way to attract a mate or just announce that he’s around. It’s also an alarm call if the peacock spots a potential predator. People in the olden days observed this behavior and thought the peacock might really be crying. That led to the stories about his supposedly ugly feet, because the rest of the bird is so beautiful that he couldn’t possibly be crying about the rest of his appearance.

There’s another species of peacock that’s just as spectacular as the Indian peacock, although it’s less well known because it’s harder to keep in captivity. The green peafowl lives in many parts of southeast Asia and is endangered due to habitat loss, poaching, and capture for the illegal pet trade. It’s more lightly built than the Indian peacock but the male can have an even longer train, over six and a half feet long, or 2 meters. The male is green and blue all over. The female is also mostly green, but with coppery speckles on her neck. Both have crests, although they point straight up instead of back.

That brings us to a mystery peacock, although fortunately it’s not a mystery anymore, or not as much of one.

At the beginning of the 20th century, the Congo basin in central Africa was colonized by Belgium, and Belgian authorities kept hearing interesting reports from local people and colonizers alike about a strange, shy animal that lived in the forest. In 1913 a small expedition was sent to find the animal, but it failed. Eventually the animal was discovered by scientists, and we know it by the name okapi. We talked about it in episode 218. (It’s not a peacock, it’s a relative of the giraffe.) One of the scientists in the expedition was James Chapin, and while he was in Africa he bought some feather headdresses from local people and took them home to examine the feathers.

He was able to identify all but one of the feathers. The mystery feather looked like it came from a guineafowl or pheasant, but it was too big and didn’t quite match any known species. Chapin set the mystery feather aside to look at again when he had more time.

Twenty-one years later, in 1936, Chapin visited a museum in Belgium to study a big collection of taxidermied birds that had been donated in 1914. The museum specialized in items and animals from central Africa, so when Chapin noticed two stuffed birds that looked like pheasants, he knew there was something weird going on with them. True pheasants aren’t found in Africa. The card attached to the specimens said they were young peacocks, and that didn’t make sense either. Peacocks are only found in Asia.

Chapin examined the birds and realized that they really were an unusual type of peacock. Not only that, he recognized the feathers. His mystery feather from 1915 matched the mystery peacock.

The following year, Chapin traveled to the Congo to look for the bird in the wild. Sure enough, it was there!

The Congo peacock looks a lot like a turkey at first glance, or a big guineafowl. Instead of a long train, the male has a more turkey-like fan of tail feathers, but they’re deep blue and black in color. He also has blue on his wings and his neck is red, with a black head with a black and white crest. The female has a red neck with a red crest, and her back is green while the rest of her is a soft brown. We don’t know a whole lot about the bird, but it’s increasingly threatened by habitat loss and hunting.

The Congo peacock isn’t a true peacock, although it’s very closely related. While the male does fan his tail during courtship displays, he’s actually fanning a different set of feathers than true peacocks. A peacock’s train is actually made up of the upper tail coverts, a set of feathers near the tail but not actually making up the tail. A peacock’s actual tail feathers are shorter and bronzey-brown in color.

All peacocks can fly, even males with the longest trains, although they prefer to spend most of the time on the ground. Outside of mating season, males shed the long feathers of their train and regrow them the following year. Many zoos that keep peacocks will collect these shed feathers and sell them so that people can use them in crafts and decorations, because everyone loves peacock feathers.

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:

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

This week we’re going to revisit a bird that everyone’s heard of but no one has seen alive, because it’s famously extinct. We talked about the dodo way back in episode 19, so it’s definitely time we talked about it again. Thanks to Wilmer and Carson for suggesting it! We’re also going to learn about some of the close relations of the dodo.

The first report of a dodo was in 1598 by Dutch sailors who stopped by the island of Mauritius in the Indian Ocean. Mauritius is east of Madagascar, which is off the eastern coast of Africa. The last known sighting of a dodo was in 1662, just 64 years later. The dodo went extinct so quickly, and was so little known, that for a couple of centuries afterwards many people assumed it was just a sailor’s story. But there were remains of dodos, and in the 19th century scientists gathered up everything they could find to study the birds. More remains were found on Mauritius.

In the wild, the dodo was a sleek bird that could run quite fast. It may have eaten crabs and other small animals as well as roots, nuts, seeds, and fruit. It was also probably pretty smart. People only thought it was dumb because it didn’t run away from sailors—but it had no predators on Mauritius so never had to worry about anything more dangerous than an occasional egg-stealing crab before.

When humans arrived on Mauritius, they killed and ate dodos and their eggs. What the sailors didn’t eat, the animals they brought with them did, like pigs and rats. It was a stark and clear picture of human-caused extinction, shocking to the Victorian naturalists who studied it.

A lot of the drawings and paintings we have of dodos were made from badly taxidermied birds or from overfed captive birds. At least eleven live dodos were brought to Europe and Asia, some bound for menageries, some intended as pets. The last known captive dodo was sent to Japan in 1647.

The dodo grew over three feet tall, or almost a meter, with brown or gray feathers, a floofy tuft of gray feathers as a tail, big yellow feet, and a weird head. The feathers stopped around the forehead, making it look sort of like it was wearing a hood. Its face was bare and the bill was large, bulbous at the end with a hook, and was black, yellow, and green. The dodo looks, in fact, a lot like what you might expect pigeons to evolve into if pigeons lived on an island with no predators, and that’s exactly what happened.

The dodo’s closest living relation is the Nicobar pigeon, which can grow 16 inches long, or over 40 cm. Like other pigeons, the dodo’s feathers probably had at least some iridescence, but the Nicobar pigeon is extra colorful. Its head is gray with long feathers around its shoulders like a fancy collar, and the rest of its body is metallic blue, green, and bronze with a short white tail. Zoos love to have these pigeons on display because they’re so pretty. It’s a protected animal, but unfortunately it’s still captured for sale on the pet black market or just hunted for food. It only lays one egg a year so it doesn’t reproduce very quickly, and all this combined with habitat loss make it an increasingly threatened bird. Scientists are trying to learn more about it so it can be better protected.

The Nicobar pigeon lives on a number of islands in the South Pacific and it can fly. Sometimes an errant individual is discovered in Australia, often after storms. Imagine going into your back yard one day and seeing a 40-centimeter-long bird whose feathers shine like jewels! The Nicobar pigeon lives in small flocks and eats seeds, fruit, and other plant material.

An even closer relative to the dodo is also the most mysterious. We don’t even know for sure if it’s extinct, although that’s very likely. It’s the spotted green pigeon and we only have one specimen–and we don’t even know where it was collected, just that it was an island somewhere in the South Pacific. There used to be two specimens, but no one knows what happened to the second one.

For a long time researchers weren’t even sure the spotted green pigeon was a distinct species or just a Nicobar pigeon with weird-colored feathers, but in 2014, DNA testing on two of the remaining specimen’s feathers showed it was indeed a separate species. Researchers think the spotted green pigeon, the dodo, and another extinct bird, the Rodrigues solitaire, all descended from an unknown pigeon ancestor that liked to island hop. Sometimes some of those pigeons would decide they liked a particular island and would stay, ultimately evolving into birds more suited to the habitat.

The specimen we have of the spotted green pigeon is 13 inches long, or 32 cm. Its feathers are dark brown with green iridescence and it has long neck feathers like the Nicobar pigeon. It also has little yellowish spots on its wings and a yellow tip to its bill. Researchers think it was probably a fruit-eating bird that lived in treetops.

The only reason we know there were once two specimens of this mystery bird is from a book about birds published in 1783, where the author mentions having seen two specimens. There was also an 1823 book about birds with an illustration of the spotted green pigeon that differs from the known specimen in some details. Researchers think the illustration might have been painted from the now-missing specimen.

There’s more to this mystery, though, because in 2020 an ornithologist studied a 1928 book about Tahiti that mentioned a bird that sounds a lot like the spotted green pigeon. It was even called a pigeon in the book. Since the author of that book had drawn on studies made by her grandfather almost a hundred years before, and since her grandfather had interviewed Tahitians about their history and traditions and they told him about the pigeon, the ornithologist suggested the spotted green pigeon might actually be from Tahiti. Now that scientists have a clue about where to start looking for remains of the bird, we might learn more about it soon.

Also in 2020, a study was published about another pigeon from the Pacific Islands. Fossils of it were found on the island of Tonga, and the scientists determined that the bird probably went extinct soon after humans first arrived on the island 2,850 years ago. The pigeon has been named Tongoenas burleyi. It grew about 20 inches long, or 50 cm, not counting its tail. It could fly and probably spent a lot of its time in trees, eating fruit. There are lots of different trees on the island that produce really big fruit, some of it as big as a tennis ball. Scientists think the pigeon was adapted to swallow these huge fruits whole, digest them, and poop out the seeds. The trees still exist but they’re in decline and scientists think it may be because no birds remain on the island that can spread their seeds effectively.

We don’t have any feathers from the newly described pigeon, but it was probably colorful. We do have a lot of bones, because many charred bones have been discovered in cooking pits excavated by archaeologists.

We don’t know yet how or if Tongoenas is related to the dodo. The Pacific islands are home to at least 90 living species of pigeon, and many of them we don’t know much about. There are undoubtedly many more waiting to be discovered by scientists, whether living or extinct.

Episode 361: The New Hominin

Welcome to 2024! Let’s learn about some exciting new discoveries in our own family tree!

476,000-Year-Old Wooden Structure Unearthed in Zambia

Mysterious 300,000-year-old skull could be new species of human, researchers say

Show transcript:

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

It’s time to start the new year off with an episode that has me really excited. I was initially going to include this in the updates episode that usually comes out around summertime, but I just can’t wait. In 2023, scientists discovered what they think might be a new lineage of extinct human ancestors!

We’ll come back to that in a moment, but first I want to highlight another amazing human-relateded discovery from 2023.

And just to let you know, I am going to be using the words “humans” and “people” and “hominins” more or less interchangeably. I try to make it clear when I’m talking about Homo sapiens versus other species of ancient hominin, but these are all our ancestors–in many cases our direct ancestors–so they’re all people as far as I’m concerned.

As you may know, especially if you’ve listened to previous episodes where we’ve discussed ancient human ancestors, the ancestors of all humans evolved in Africa. Specifically, we arose in the southern part of Africa, in areas that had once been dense forest but gradually changed to open woodland and savanna. Because there weren’t very many trees, our far-distant hominin ancestors, the australopiths, no longer needed to be able to climb trees as well as their ape cousins. Instead, they evolved an upright stance and long legs to see over tall grasses, and the stamina to run after the animals they hunted until the animal was exhausted and couldn’t run anymore. Once our ancestors were walking on two legs all the time, their hands were free to carry babies and food and anything else they wanted.

Being fully bipedal meant that women had a harder time giving birth, since the pelvis had to change position to allow them to walk and run, so babies started being born when they were smaller. This meant the babies needed a whole lot more care for a lot longer, which meant that family groups became even more important and complicated. One thing we’ve learned about sociability in animals is that it leads to increased intelligence, and that’s definitely what happened with our long-distant ancestors. As their brains got bigger, they became more creative. They made lots of different types of tools, especially weapons and items that helped them process food, but eventually they also made artwork, baskets, clothing, jewelry, and everything else they needed.

All this took a long time, naturally. We know Australopithecus used stone tools over three million years ago, but we don’t have evidence of human ancestors using fire until a little over 1.5 million years ago. Homo sapiens was once thought to have only evolved around 100,000 years ago, maybe less, but as scientists find more remains and are able to use more sophisticated techniques to study those remains, the date keeps getting pushed back. Currently we’re pretty certain that actual humans, if not the fully modern humans alive today, arose about 300,000 years ago and maybe even earlier. Homo sapiens evolved from Homo erectus, which arose about two million years ago and went extinct about 100,000 years ago. They were probably the first hominin to use fire, which allowed humans to start migrating longer distances into colder climates. They might also have communicated with language. Basically, Homo erectus was a lot like us but not quite us yet.

The modern-day country of Zambia is in the middle of south-central Africa, and naturally it’s been home to humans and our ancestors for as long as humans have existed. One especially important part of Zambia is also one of its most beautiful places, Kalambo Falls, which is really close to the equally important and beautiful country of Tanzania. Scientists have known that humans of one kind or another have lived around Kalambo Falls for at least 447,000 years, long before Homo sapiens actually evolved.

When a team of archaeologists excavated a sandbar near the falls in 2019, they were surprised to find wooden artifacts. Wood doesn’t usually preserve for very long and the site they were excavating was quite old. In addition to wooden tools, they found two logs that had been shaped and notched to allow them to fit together securely. The researchers thought the logs had once been part of a structure like a walkway that would keep people’s feet out of the mud and water, or possibly the floor of a wooden structure used to store food. It might even have been the floor of a little house.

Wood can be dated with simple tests to find out its age, but the test is only useful for trees that died within the last 50,000 years. Anything older than that is just, you know, older than 50,000 years. The tools and logs tested as older, which the scientists expected. Fortunately there are other ways to date older wood, but the results of those tests were surprising even to the scientists. The tools were at least 324,000 years old, possibly as much as 390,000 years old, but the logs were even older, about 476,000 years old.

Remember, Homo sapiens didn’t even evolve until about 300,000 years ago. That means humans didn’t make those tools or build anything with those shaped logs. Some other hominin did, although we’re not sure who. Even more exciting, close examination of the logs suggests that they may have been subjected to fire at some point. That might mean a natural fire or it might mean that the people who were building with the logs were also using fire as much as two million years before we thought people were using fire.

Obviously scientists are going to look carefully for more clues about who might have shaped these logs and when. Hopefully we’ll learn more soon.

Around the same time that scientists uncovered the wooden items in southern Africa, another discovery was made in 2019, this one in East China. A team found a jaw, skull, and leg bones of a hominin that didn’t match up to any known human ancestor. The bones were dated to 300,000 years ago, at the dawn of Homo sapiens. Other hominins had migrated to eastern Asia long before this, however, including populations of Homo erectus.

The newly discovered bones don’t belong to Homo erectus, though. They don’t belong to Homo sapiens either, or any other known hominin. They represent a completely new hominin, and at the moment scientists don’t know where exactly they fit in our own family tree.

The bones show traits found in modern humans, like a flat face, but lack other uniquely human traits, most notably a chin. Homo sapiens have chins, unlike every other hominin, and no one’s sure why. It might have something to do with speech or maybe early humans with chins were just considered more attractive, and now everyone has a chin.

The mystery hominin is still being studied, but preliminary findings indicate that we might have discovered the ancestor of a very close relation. The bones show some traits also found in Neandertals, our very closest evolutionary cousins, even though they’re extinct. There’s a possibility that this new hominin gave rise to another line of very close human relations, one we don’t have any fossils of yet.

I know there are a lot of excited scientists wanting to learn more about the hominin bones. Hopefully more bones will turn up soon so we can get a better idea of who this distant relative is. It’s a little too early to throw them a welcome home party, but maybe we can start planning it now.

Episode 356: The Volcano Rabbit

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

This week we have a suggestion from Eva, who wanted to learn about volcano rabbits! What are volcano rabbits? Do they shoot lava at their enemies? Let’s find out! (No, they don’t shoot lava. Sorry. That’d be awesome!)

The most important thing to know about the volcano rabbit is how small it is. It’s almost the smallest rabbit known. It typically only grows about 9 inches long, or 23 cm, and that’s when it’s stretched out. Rabbits usually sit more bunched up, which makes it look even smaller. Its ears are small and rounded, its tail is short even for a rabbit, and its legs are short. Its fur is also short and very thick, mostly grayish-tan in color.

The second most important thing to know about the volcano rabbit is how rare and endangered it is. That’s because it only lives in one small part of Mexico, specifically on the upper slopes of four volcanoes. Because people also live in this area, which isn’t far from Mexico City, the rabbits’ natural range is fragmented by human-made obstacles like highways that are dangerous for it to cross, along with habitat destruction from logging, livestock grazing, and the building of new houses. People even hunt the rabbit even though it’s a protected animal. We don’t know for sure how many of the volcano rabbits are left in the wild, but the best estimate is around 1,200 rabbits in small populations that are often widely separated. It’s even been declared extinct on another volcano where it used to live, although there may be a small population still hanging on.

The volcano rabbit prefers open woodland in higher elevations where there’s plenty of tall, dense grass native to the area. It makes rabbit-sized tunnels through the grass so it can move around undetected by predators. It also mostly eats this grass. It’s most active at dawn and dusk, which also helps it hide from predators.

When a volcano rabbit does feel threatened, it doesn’t thump its feet to alert other rabbits of danger. Instead, it gives a little alarm squeal. This is really unusual in a rabbit, but it’s something the pika does, and the pika is closely related to rabbits. The pika lives in parts of central Asia and western North America, especially in cold areas like mountaintops. It’s so well adapted to the cold that it can die if the temperature climbs over about 78 degrees Fahrenheit, or 25 Celsius.

The American pika actually looks a lot like the volcano rabbit in some ways, although it’s less rabbit-like in shape and more rodent-like, although it’s not a rodent. It’s a lagomorph. It’s about the same size or a little smaller than the volcano rabbit, with short legs and dense grayish-brown fur that grows longer in winter. It especially likes places with a lot of rocks, since it makes its home in little cracks and crevices between rocks. It prepares for winter by harvesting the plants it eats and storing them in little haypiles. Since it doesn’t hibernate, it needs plenty of food for times when snow and ice make it hard to find plants.

The pika is intensely territorial, because it doesn’t want any other pikas sneaking around eating up its hay, but it does communicate with other pikas. During breeding season the males will make a singing call to attract a female, and all pikas will call to warn others of a predator nearby. I couldn’t find any recordings of a volcano rabbit, but this is what an American pika sounds like:

(wait for it…)

[pika beeping]

Like other rabbits, the volcano rabbit eats grass and other plant parts. The problem is that most of the plants in its habitat are not very high in protein. The more fragmented its habitat is, the harder it is for the rabbits to find enough food to survive, much less to also reproduce. Every time someone decides to let cattle or other livestock graze on the local plants, the rabbits have that much less food.

Fortunately, conservationists in Mexico are working on educating people so they know this cute little rabbit is a protected species. Captive breeding programs are underway too, and parts of the volcanoes where the rabbit lives are within the bounds of a national park. There are plans to create safe corridors to link the rabbit’s fragmented habitats so it can come and go without getting squished by cars, and to restore its range with more native plants so it has plenty of food.

You might worry that the volcano rabbit, besides having all these issues with habitat loss and habitat fragmentation, is also in danger of its volcano home erupting. The volcanoes where it lives are active, but only one of the four poses any danger, and that volcano has erupted repeatedly in the last several hundred years without affecting the volcano rabbit. It actually even had a small eruption in May 2023. Schools in the area were closed for a few days, but no one was hurt, not even a rabbit.

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

This week as monster month continues, we’ll learn about three more strange bipedal monsters suggested by Will and Pranav. This is another episode that I’ll give three out of five bats for spookiness. We’ve definitely got some spooky monsters this year (also you may be sensing a theme).

We’ll start with Will’s suggestion, the yara-ma-yha-who. We talked about it once before back in episode 219, but it’s such a strange monster that it definitely deserves more attention.

According to a 1932 book called Myths and Legends of the Australian Aboriginals, the yara-ma-yha-who is a little red goblin creature that stands about four feet tall, or 1.2 meters. It’s skinny all over except for its head and belly, and its mouth is especially big, like a frog’s mouth. It doesn’t have any teeth, but it can open its jaws incredibly wide like a snake, which allows it to swallow its food whole. And what is its food? People!

The yara-ma-yha-who was supposed to live in trees, especially the wild fig tree that has thick branches. In the summer when someone would stop under the tree for shade, or in the winter when it was rainy and someone would stop for shelter, the yara-ma-yha-who would drop down and grab the person.

The ends of the yara-ma-yha-who’s fingers were said to be cup-shaped suckers, and when the suckers fastened onto a person’s arm, they were able to suck blood right through the person’s skin. After the person became weak from blood loss and fainted, the yara-ma-yha-who was able to swallow them whole.

After that, the yara-ma-yha-who would drink a lot of water and fall asleep, and when it woke up it would vomit up its meal. If the person was still alive, they were supposed to lie still and pretend to be dead even while the yara-ma-yha-who poked at them to see if they responded. If the person moved, the yara-ma-yha-who would swallow them again and the whole thing would start over. But every time a person was swallowed by the little red goblin, when they were vomited up again they were shorter and redder, until after three or four times if they couldn’t get away, the person was transformed into another yara-ma-yha-who.

Some cryptozoologists speculate that the yara-ma-yha-who may be based on the tarsier, which is the subject of episode 219 and why we talked about this particular monster in that episode. The tarsier has never lived in Australia, although it does live in relatively nearby islands. Most tarsier species have toe pads that help them cling to branches, but so do many frogs that do live in Australia. It’s much more likely that the legend of the yara-ma-yha-who was inspired by frogs, snakes, monitor lizards, and other Australian animals. More importantly, the monster was used as a cautionary tale to warn children not to go off by themselves into the bush.

Unfortunately, the only information about the yara-ma-yha-who comes from this 1932 book. We don’t know which Aboriginal peoples this story was collected from, and we don’t know how much it was changed in translation to English. It’s still a fun story, though.

Next, we’ll talk about Pranav’s suggestions. Last week we talked about the monkey-man of New Delhi, and one of the monsters we’ll cover today is also a monkey-man from Asia, this time from Singapore. It’s the Bukit Timah Monkey-Man, said to mainly live in the Bukit Timah rainforest nature reserve but occasionally seen in the city surrounding the nature reserve.

The Bukit Timah Monkey-Man is supposed to look like a monkey the size of a human. It walks like a human on two legs and otherwise looks like a person, but is covered in gray hair and has a monkey-like face. It’s only ever seen at night and although people are scared when they see it, the monster has never attacked anyone and doesn’t seem to be interested in people at all. The oldest report possibly dates back to 1805, or to the 1940s according to other accounts, but sightings are rare.

One very common monkey that lives in Bukit Timah is the crab-eating macaque, also called the long-tailed macaque and I bet you can guess why. Its tail is longer than its body, although its arms and legs are shorter than in most monkeys. It mostly lives on the ground and eats pretty much anything, although most of its diet is fruit and other plant materials. It does sometimes eat crabs, and is good at swimming and diving to find them, but it also eats bird eggs and nestlings, lizards, frogs, insects, and other small animals. It even has a cheek pouch where it can store extra food to eat later.

Like the rhesus macaque we talked about last week, the crab-eating macaque is pretty small, with a big male weighing about 20 lbs, or 9 kg, at most. That’s about the size of a small dog. The fur on its back and head is a light golden brown, and its face, arms and legs, and underparts are gray with white markings. Its tail is usually darker brown. In other words, in the dark it might look like it’s pale gray all over but its tail is harder to see, and the monkey-man isn’t reported to have a tail.

The crab-eating macaque is common in the city of Bukit Timah, and in fact it’s common in a lot of cities and is even an invasive species in some parts of the world. People in Bukit Timah are used to seeing this particular type of monkey, but it’s so small that no one could mistake it for a human-sized monster. Then again, most of the stories about the monkey-man are friend-of-a-friend stories, often told by children to scare each other. It’s very likely that the Bukit Timah monkey-man is just an urban legend.

Our last monster this week is another suggestion by Pranav, the Honey Island Swamp monster. This one is from the United States, specifically the Honey Island Swamp in St. Tammany Parish, Louisiana.

In 1974, a couple of hunters claimed they found strange footprints in the swamp, and had seen the monster itself back in 1963. They said it stood seven feet tall, or over 2 meters, and was covered with long gray hair. Its eyes were a brilliant amber in color. The monster was on all fours at first, but when it heard the men talking it stood up to look at them, then ran away. Heavy rain later that day washed its tracks away.

When the men saw the same tracks in 1974, they used plaster to make copies of the footprints. But the footprints don’t look like plaster casts of other bigfoot-type tracks, which resemble giant human footprints. The swamp monster appears to have four toes that are spread widely apart, with one sticking out to the side like a thumb, and show the impression of webbing in between. It’s also not that big of a foot, not quite 10 inches long, or 25 cm.

Both the hunters were air traffic controllers, which is a job that requires people to make decisions carefully and remain calm in stressful situations, in order to keep airplanes from crashing into each other. These were the sort of people you’d trust if they told you they’d seen something really weird in the swamp. The two men were even interviewed for an episode of the TV show “In Search Of” that aired in 1978, which popularized the Honey Island Swamp monster outside of the local area. Both men continued to search for the monster, reporting that they’d caught at least one more glimpse of it and had even shot at it without apparently hitting it.

One of the men, Harlan Ford, died in 1980. He had taken up wildlife photography after his retirement and when his granddaughter was going through his belongings, she found some Super 8 film footage that showed something very peculiar. It was a brief video of the swamp, but if you look closely, a shadowy human-sized figure crosses behind trees from right to left, visible for maybe half a second. I put a link in the show notes if you want to look at the footage yourself. It took me two watches before I noticed the figure and to me it looks like the shadow of a human walking normally, but it’s so grainy it’s hard to tell.

It’s possible that the two men decided to have fun with a harmless prank about a monster in the swamp, but so many people took them seriously that it kind of got out of hand. Then again, maybe they did genuinely see something unusual. That doesn’t mean it was an actual monster, though. Black bears do live in the swamp, and my personal theory is that bears are responsible for a whole lot of bigfoot sightings.

The American alligator is also common in the area. The gator’s front feet have five toes, but the hind feet only have four. The toes are webbed to help the gator swim more easily, and the front foot’s pinkie toe usually sticks out to the side. Sometimes the first two toes of the front foot are held close enough together that they look like one big toe. Usually an alligator drags its tail as it walks, but it also has a gait called the high walk where its tail is completely off the ground. The plaster tracks found by the two hunters in 1974 look suspiciously like a really big alligator print, probably twice the size of an ordinary adult gator.

More importantly, people who have lived in the Honey Island swamp their entire lives, fishing and hunting and running boat tours, don’t report ever seeing an animal they don’t recognize. Maybe there is an incredibly rare monster that lives in the swamps and walks bipedally at least part of the time, but more likely the Honey Island Swamp Monster is a tall tale.

There are a lot of reasons why people tell stories about swamp monsters or monkey-men or murderous red goblins. It’s a good way to stop little kids from wandering around in dangerous places, and it’s fun to scare yourself and others with a story when you know you’re actually safe. There are plenty of dangerous animals in the world, many of which are completely unknown to science. I just don’t think these three are ones you need to worry about.

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

As monster month continues, this week we have a really spooky episode on a topic Pranav suggested a long time ago. I’m rating it three out of five bats, meaning that if you’re one of our younger listeners, you might want to skip this one or make sure to listen to it in the daytime with your favorite grown-ups around you. It’s about the monkey-man of New Delhi, but we’re also going to talk about one of my favorite monsters too as part of it.

In May of 2001, several families made a strange complaint to the police in the city of Ghaziabad in India, near the capital city of New Delhi. A masked man had sneaked into their homes and pushed and scratched people before running away into the darkness. No one was badly injured, but they were definitely scared.

Then other people started reporting something similar in parts of East Delhi. People were left with scratches and bruises caused by a masked man, according to some witnesses. But others said they were attacked by a monkey.

As the reports flooded in over the next few days, the reports got stranger and stranger. The attacker was said to be a man with a monkey-like face, a big monkey wearing skin-tight clothes and a helmet, a creature with black fur and glowing cat eyes, even a robot with metal claws. It could reportedly jump incredibly high and even disappear. No one could agree on what the attacker looked like, but before long everyone was jumpy and ready to run if they even thought the strange creature was nearby. This sadly led to at least two people dying on different occasions when they panicked and tripped down stairs.

The police tried their best to find the culprit, but it was always gone before they arrived. Meanwhile, the news media exaggerated the reports and whipped people into a frenzy of fear. But despite all the sightings, no one ever got even a blurry photo of the so-called monkey-man. When the police questioned people who were supposedly attacked, most of them admitted that they hadn’t really seen anything. Often they only felt the presence of the monkey-man, and later noticed bruises or scratches that might have been caused by ordinary events during the day.

Weird as all this sounds, it isn’t the first time such a strange situation has happened in a big city. In 1837, in London, England, a very similar creature caused a very similar panic. The main difference is that instead of a monkey-man, the London monster was more like a devil, sometimes said to have horns and bat wings. He was called spring-heeled Jack.

Spring-heeled Jack got his nickname because he was supposed to be able to jump incredibly high, as though he had springs in his boots. Some reports said the creature had claws, possibly metal ones, that he could shoot sparks or blue fire from his mouth, that he had glowing red eyes, and that his hands felt cold and clammy like a corpse. Some people even referred to him as a ghost.

The monster was supposed to have attacked young women in particular, scratching them with his claws. In the most famous case, a teenaged girl named Jane Alsop was at home in February 1838 when someone knocked on the door and shouted that he was a police officer who had caught spring-heeled Jack! The officer asked for a light, since it was a dark evening, but when Jane brought a candle outside, instead of meeting a valiant police officer who had caught a monster, she only encountered the monster himself. Spring-heeled Jack grabbed her by the neck!

With the help of her sisters, who heard her screams, Jane was able to tear herself away from the monster with only some scratches on her arms and neck. Spring-heeled Jack bounded away into the night. Another encounter only nine days later happened to eighteen-year-old Lucy Scales, who was returning home with her sister in the evening. As they passed an alley, a man wearing a large black cloak jumped out at Lucy, spat blue flame into her face, and hurried away when she collapsed in shock.

As in India over 150 years later, the newspapers printed sensationalized reports of the attacks that made things even worse. The police arrested various men at different times, but there was no evidence that any of them had attacked the women or had dressed up as spring-heeled Jack. The scratches and bruises reported by victims weren’t actually that bad, and might have been caused by anything. In the end, the reports gradually stopped, although there was a brief revival of reports in the 1870s, over 30 years later.

So what’s going on here? Could spring-heeled Jack and the monkey-man of New Delhi be reports of the same creature or entity, with details differing between the two monsters because of the cultural differences of people reporting those details? Where people in modern India might think they see a monkey-man, because monkeys are common in India, people in old-timey England might have though they saw a demonic man since devils and demons were a common aspect of English culture at the time.

Let’s look at the details that both monsters share. Both are mostly described as being human-like in shape. Both walk on two legs, have two arms and a head with human-like features, or at least primate-like features. This argues that the monsters must be some sort of primate. Spring-heeled Jack in particular was always mistaken for an ordinary man at first, so instead of a monkey, he must have been a great ape, and more likely a hominin, or human or human relation. The reports of the monkey-man of New Delhi are less detailed and more varied, but the initial reports and many later ones called him a man, meaning a human male.

In other words, logically both monsters can’t be extraterrestrial creatures or they wouldn’t look and act so similar to earth creatures. Both also had physical aspects, able to interact with people and things normally, so even though some people called spring-heeled Jack a ghost, he actually seemed to be a living creature. And both seemed to be human, or at least human-like.

Maybe the monsters in both cases were just humans.

Some historians think that both the monkey-man and spring-heeled Jack weren’t real monsters at all but urban legends, and most if not all of the reports were caused by mass hysteria. Mass hysteria is a real condition, although it’s rare, where a group of people become convinced that they’re in danger in some way despite a lack of real evidence. Sometimes the group of people will think they’ve been exposed to a dangerous chemical or poison, and will actually show physical symptoms of illness. The symptoms go away after a while with no lasting health issues, but for the people who feel sick, it’s completely real and very scary.

Mass hysteria happens when rumors of danger get repeated so much that people start to believe the danger even though there’s no evidence that it exists. Newspaper and social media reports contribute to the feeling that danger is imminent, and before long everyone’s jumpy and ready to believe any ridiculous story they hear.

In the case of spring-heeled Jack, the very first reports may have been real attacks on people by someone who was trying to scare them or even rob them. Once rumors and newspaper reports got started, before long people were convinced that a dangerous monster was bouncing around in London terrorizing people.

As for the monkey-man, there are many species of monkey that live in India, including some that have moved into cities as cities grow larger and the wilderness areas grow smaller. As many as 40,000 monkeys live in New Delhi alone, mostly rhesus macaques that often steal food, phones, and other items from people. It’s a brown or gray monkey with a pink face and a short tail, and in its natural habitat it spends most of its time in treetops. The rhesus macaque can walk on its hind legs pretty well, but it’s not very big, rarely weighing more than a domestic cat. It eats fruit and other plant material, and while it can be aggressive to humans, most of the time it’s not dangerous. Not only that, but people who live in Delhi and other cities are familiar with the macaques and aren’t afraid of them.

In other words, it’s not very likely that the monkey-man of New Delhi was an actual monkey. The initial reports might have been of a man who was trying to rob people’s homes, or it might even have started when someone had a bad dream. After that, rumors and media accounts made people think they were in danger from the monster.

The next time you start to hear rumors that people are in danger, and the rumors get wilder and wilder, remember the monkey-man and spring-heeled Jack. Take a moment to look at the situation logically, and decide if it’s more likely that a weird monster with metal claws and the ability to jump as high as a rooftop is really running around scaring people, or if that could be an urban legend. Urban legends are fun, but you don’t have to be afraid of them.

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

It’s officially monster month, also known as October, so let’s jump right in with a topic suggested by Anbo! Anbo wanted to learn about Australopithecus, and while we’re at it we’re going to talk about Gigantopithecus and Bigfoot. On our spookiness rating scale of one to five bats, where one bat means it’s not a very spooky episode and five bats means it’s really spooky, this one is going to fall at about two bats, and only because we talk a little bit about the Yeti and Bigfoot at the end.

In 1924 in South Africa, the partial skull of a young primate was discovered. Primates include monkeys and apes along with humans, our very own family tree. This particular fossil was over a million years old and had features that suggested it was an early human ancestor, or otherwise very closely related to humans.

The fossil was named Australopithecus, which means “southern ape.” Since 1924 we’ve discovered more remains, enough that currently, seven species of Australopithecus are recognized. The oldest dates to a bit over 4 million years old and was discovered in eastern Africa.

Australopithecus was probably pretty short compared to most modern humans, although they were probably about the size of modern chimpanzees. A big male might have stood about 4 ½ feet tall, or 1.5 meters. They were bipedal, meaning they would have stood and walked upright all the time. That’s the biggest hint that they were closely related to humans. Other great apes can walk upright if they want, but only humans and our closest ancestors are fully bipedal.

In 2008 a palaeoanthropologist named Lee Rogers Berger took his nine-year-old son Matthew to Malapa Cave in South Africa. Dr. Berger was leading an excavation of the cave and Matthew wanted to see it. While he was there, Matthew noticed something that even his father had overlooked. It turned out to be a collarbone belonging to an Australopithecus boy who lived almost 2 million years ago. Later, Dr Berger’s team uncovered more of the skeleton and determined that the remains belonged to a new species of Australopithecus, which they named Australopithecus sediba. More remains of this species were discovered later, including a beautifully preserved lower back. That discovery was important because it allowed scientists to determine that this species of Australopithecus had already evolved the inward curve in the lower back that humans still have, which helps us walk on two legs more easily. That was a surprise, since A. sediba also still shows features that indicate they could still climb trees like a great ape.

It’s possible that Australopithecus, along with other species of early humans, climbed trees at night to stay safe from predators. In the morning, they climbed down to spend the day mostly on the ground. One study published only a few weeks ago as this episode goes live suggests that the flexible shoulders and elbows that humans share with our great ape cousins originally evolved to help apes climb down from trees safely. Monkeys don’t share our flexible shoulder and elbow joints because they’re much lighter weight than a human or ape, and don’t need as much flexibility to keep from falling while climbing down. Apes and hominins like humans can raise our arms straight up over our heads, and we can straighten our arms out completely flat. Australopithecus could do the same. The study suggests that when another human ancestor, Homo erectus, figured out how to use fire, they stopped needing to climb trees so often. They evolved broader shoulders that allowed them to throw spears and other weapons much more accurately.

Australopithecus probably mostly ate fruit and other plant materials like vegetables and nuts, along with small animals that they could catch fairly easily. This is similar to the diet of many great apes today. The big controversy, though, is whether Australopithecus made and used tools. Their hands would have been more like the hands of a bonobo or chimpanzee, which have a lot of dexterity, but not the really high-level dexterity of modern humans and our closest ancestors. Stone tools have been found in the same areas where Australopithecus fossils have been found, but we don’t have any definitive proof that they made or used the tools. There were other early hominins living in the area who might have made the tools instead.

We also don’t really know what Australopithecus looked like. Some scientists think they had a lot of body hair that would have made them look more like apes than early humans, while some scientists think they had already started losing a lot of body hair and would have looked more human-like as a result.

There’s no question these days that Australopithecus was an early human ancestor. We don’t have very many remains, but we do have several skulls and some nearly complete skeletons, which tells us a lot about how our distant ancestor lived. But we know a lot less about a fossil ape that lived as recently as 350,000 years ago, and it’s become confused with modern stories of Bigfoot.

Gigantopithecus first appears in the fossil record about 2 million years ago. It lived in what is now southern China, although it was probably also present in other parts of Asia. It was first discovered in 1935 when an anthropologist identified two teeth as belonging to an unknown species of ape, and since then scientists have found over a thousand teeth and four jawbones, more properly called mandibles.

The problem is that we don’t have any other Gigantopithecus bones. We don’t have a skull or any parts of the body. All we have are a few mandibles and lots and lots of teeth. The reason we have so many teeth is because Gigantopithecus had massive molars, the biggest of any known species of ape, with a protective layer of enamel that was as much as 6 mm thick. Some of the teeth were almost an inch across, or 22 mm. A lot of the remaining bones were probably eaten by porcupines, and in fact the mandibles discovered show evidence of being gnawed on. This sounds bizarre, but porcupines are well-known to eat old bones along with the shed antlers of deer, which supplies them with important nutrients. The teeth were too hard for the porcupines to eat.

We know that Gigantopithecus was a big ape just from the size of its mandible, but without any other bones we can only guess at how big it really was. It was potentially much bigger and taller than even the biggest gorilla, but maybe it had a great big jaw but short legs and it just sat around and ate plants all the time. We just don’t know.

What we do know is that its massive jaw and teeth were adapted for eating fibrous plant material, not meat. The thick enamel would help protect the teeth from grit and dirt, which suggested it ate tubers and roots that would have had a lot of dirt on them, although its diet was probably more varied. Scientists have even discovered traces of seeds from fruits belonging to the fig family stuck in some of the fossilized teeth, and evidence of tooth cavities that would have resulted from eating a lot of fruit long before toothpaste was invented.

Many scientists thought at first that Gigantopithecus was a human ancestor, but one that grew to gigantic size. It was even thought to be a close relation to Australopithecus. Other scientists argued that Gigantopithecus was more closely related to modern great apes like the orangutan. The debate on where Gigantopithecus should be classified in the ape and human family tree happened to overlap with another debate about a giant ape-like creature, the Yeti of Asia and the Bigfoot of North America.

We talked about the Yeti way back in episode 35, our very first monster month episode in 2017. Expeditions by European explorers to summit Mount Everest, which is on the border between China and Nepal, started in 1921. That first expedition found tracks in the snow resembling a bare human foot at an elevation of 20,000 feet, or 6,100 meters. They realized the tracks were probably made by wolves, with the front and rear tracks overlapping, which only looked human-like after the snow melted enough to obscure the paw pads. Expedition leader Charles Howard-Bury wrote in a London Times article that the expedition’s Sherpa guides claimed the tracks were made by a wild hairy man, but he also made it clear that this was just a superstition. But journalists loved the idea of a mysterious wild man living on Mount Everest. One journalist in particular, Henry Newman, interviewed the guides and specifically asked them about the creature. He wrote a sensational account of the wild man, but he mistranslated their term for it as the abominable snowman.

The word Yeti comes from a Sherpa term yeh-teh, meaning “animal of rocky places,” although it may be related to the term meh-teh, which means man-bear. But the peoples who live in and around the Himalayas belong to different cultures and speak a lot of different languages. There are lots of stories about the hairy wild man of the mountains, and lots of different words to describe the creature of those stories. And the idea of the Yeti that has become popular in Europe and North America doesn’t match up with the local stories. Locals describe the Yeti as brown, black, or even reddish in color, not white, and it doesn’t always have human-like characteristics. Sometimes it’s described as bear-like, panther-like, or just a general monster.

The abominable snowman, or Yeti, became popular in newspaper articles after the 1921 Mount Everest expedition, and it continued to be a topic of interest as expeditions kept attempting to summit the mountain. It wasn’t until May 26, 1953 that the first humans reached the tippy-top of Mount Everest, the New Zealand explorer Edmund Hillary and the Nepali Sherpa climber Tenzing Norgay. Many other successful expeditions followed, including some that were mounted specifically to search for the Yeti.

In the meantime, across the planet in North America, a Canadian schoolteacher and government agent named John W. Burns was collecting reports of hairy wild men and giants from the native peoples in British Columbia. He’s the one who coined the term Sasquatch in 1929. In the 1930s, a man in Washington state in the U.S, which is close to British Columbia, Canada, carved some giant feet out of wood and made tracks with them in a national forest to scare people, leading to a whole spate of big human-like tracks being faked in California and other places. But it wasn’t until 1982 that the hoaxes started to be revealed as the perpetrators got old and decided to clear up the mystery.

But in the 1920s and later, the popularity of the abominable snowman in popular media, giant gorillas like King Kong in the movies, the Yeti expeditions in the Himalayas, the mysterious giant footprints on the west coast of North America, and John Burns’s articles about the Sasquatch all combined to make Bigfoot, a catchall term for any giant human-like monster, a modern legend. People who believed that Bigfoot was a real creature started looking for evidence of its existence beyond footprints and reports of sightings. In 1960, a zoologist writing about a photograph of supposed Yeti tracks taken in 1951 suggested that the Yeti might be related to Gigantopithecus.

On the surface this actually makes sense. The Yeti, AKA the abominable snowman, is reported in the Himalayan Mountains of Asia. The mountain range started forming 40 to 50 million years ago when the Indian tectonic plate crashed into the Eurasian plate very slowly, pushing its way under the Eurasian plate and scrunching the land up into massively huge mountains. It’s still moving, by the way, and the Himalayas get about 5 mm taller every year. The eastern section of the Himalayas isn’t that far from where Gigantopithecus remains have been found in China, and we also know that at many times in the earth’s recent past, eastern Asia and western North America were connected by the land bridge Beringia. Humans and many animals crossed Beringia to reach North America, so why not Gigantopithecus or its descendants? That would explain why Bigfoot is so big, since in 1957 one scientist estimated that Gigantopithecus might have stood up to 12 feet tall, or 3.7 meters.

Some people still think Gigantopithecus was a cousin of Australopithecus, that it walked upright but was huge, and that its descendants are still around today, hiding in remote areas and only glimpsed occasionally. But people who believe such an idea are stuck in the past, because in the last 60 years we’ve learned a whole lot more about Gigantopithecus.

These days, more sophisticated study of Gigantopithecus fossils have allowed scientists to classify it as a great ape ancestor, not an early human. Gigantopithecus was probably most closely related to modern orangutans, in fact, and may have shared a lot of traits with orangutans. It probably could walk upright if it wanted to, but it wasn’t fully bipedal the way humans and human ancestors are. One theory prevalent in 2017 when we talked about the Yeti before was that Gigantopithecus mostly ate bamboo and might have gone extinct when the giant panda started competing with its food sources. This theory has already fallen out of favor, though, and we know that Gigantopithecus was eating a much more varied diet than just bamboo.

We also know that Gigantopithecus lived in tropical broadleaf forests common throughout southern Asia at the time. About a million years ago, though, many of these forests became grasslands. Gigantopithecus probably went extinct as a direct result of its forest home vanishing. It just couldn’t find enough food and shelter on open grasslands, and even though it held on for hundreds of thousands of years, by about 350,000 years ago it had gone extinct. Around 100,000 years ago the forests started reclaiming much of these grasslands, but by then it was too late for Gigantopithecus. Meanwhile, the oldest evidence we have of the land bridge Beringia joining Asia and North America was 70,000 years ago.

There is no evidence that any Gigantopithecus descendant survived to populate the Himalayas or migrated into North America. For that matter, there’s no evidence that Bigfoot actually exists. If a live or dead Bigfoot is discovered and studied by scientists, that would definitely change a lot of things, and would be really, really exciting. But even if that happened, I’m pretty sure we’d find that Bigfoot wasn’t related to Gigantopithecus. Whether it would be related to Australopithecus and us humans is another thing, and that would be pretty awesome. But first, we have to find evidence that isn’t just some footprints in the mud or snow.

Some Bigfoot enthusiasts suggest that the reason we haven’t found any Bigfoot remains is the same reason why we don’t have Gigantopithecus bones, because porcupines eat them. But while porcupines do eat old dry bones they find, they don’t eat fresh bones and they don’t eat all the bones they find. For any bone to fossilize is rare, so the more bones that are around, the more likely that one or more of them will end up preserved as fossils. Bones of modern animals are much easier to find, porcupines or no, but we don’t have any Bigfoot bones. We don’t even have any Bigfoot teeth, which porcupines don’t eat.

Porcupines can be blamed for a lot of things, like chewing on people’s cars and houses, but you can’t blame them for eating up all the evidence for Bigfoot.

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

It’s the end of September and you know what that means: we’re about to start Monster Month! This year I have so many awesome ideas for episodes that we’re starting monster month early, with a non-spooky episode about two sort of spooky-looking amphibians. Thanks to Max for suggesting one of the animals we’re about to talk about!

Instead of rating the monster month episodes on a spookiness scale from one to five ghosts, this year we’re rating them on a spookiness scale of one to five bats, which seems more appropriate. This episode is only one bat, meaning even our younger listeners shouldn’t find it scary.

But first, a quick correction. Thanks very much to Mary for catching a mistake I made in last week’s rhinoceros episode. I said that black rhinos can weigh 18 kilograms, when I should have said 1800 kilograms. 18 kg is about 40 pounds, so I think you can agree that I made a BIG mistake.

Now, on to the “spooky” amphibians.

Lots of amphibians live in southeast Asia, many of them never seen by scientists. In 2018, a team of scientists were studying crocodile newts in Vietnam when they discovered one that didn’t look like any of the many other crocodile newts that live in Asia. Since there are over 30 species known, with new ones being discovered all the time, including seven others from Vietnam alone, they suspected this might be a species new to science.

The new newt lives in high elevations in the central highlands in Vietnam, much farther south and in much higher elevations than the other known crocodile newt species. After the initial finding in 2018, the lead scientist, an amphibian and reptile expert named Phung My Trung (apologies because I probably pronounced his name wrong) spent four years searching for more specimens and learning about them before he described it as a new species.

One thing I love is that he was quoted as saying that the adult newts “were so beautiful that I was shaking and could hardly believe I was holding a live specimen in my hand.” And it is absolutely a gorgeous animal. It’s black with orangey-red markings on its back, lovely Halloween colors, and in fact the markings sort of look like the skull, backbone, and ribs of a cartoon skeleton. Females are bigger than males, and a big female can grow as much as 3 inches long, or 7.5 cm, from snout to vent, not counting its tail that’s almost as long as its body.

That’s pretty much all we know so far about this newt. Because it appears to have such a restricted range, it’s most likely endangered due to habitat loss and climate change, but now that we know it’s there, scientists and conservationists can work to keep it and its habitat safe.

Our other amphibian this week is one suggested by Max. Max, by the way, is an incredible artist who specializes in making reptiles and amphibians out of clay. Max asked specifically about the giant screaming frog, which definitely sounds like a Halloween-themed animal.

The giant screaming frog isn’t the actual name of the frog, or at least I couldn’t find a frog with that specific name. I think it’s from an awesome video posted in 2017. I’ll put a link in the show notes if you want to watch the video, which is a YouTube channel called Brave Wilderness. In the video, a man called Coyote Peterson catches a giant frog called the Smoky Jungle Frog. When he does, the frog makes this sound:

[screaming frog!]

That doesn’t actually sound all that spooky. But it is a warning call so I bet other smoky jungle frogs think it’s terrifying!

The smoky jungle frog lives in tropical and subtropical areas of Central and northern South America, where it lives in swamps, ponds, and even rivers, especially in rainforest environments. It’s a bit unusual in that males are larger than females, although only slightly. Both males and females grow about 7 inches long from snout to vent, or 18 cm, and are a mottled brown with darker spots and stripes that help them blend in with dead leaves on the forest floor.

The smoky jungle frog is nocturnal, and during the day it stays hidden in a burrow or buries itself in fallen leaves. At night it comes out to find food, and because it’s such a big, strong frog, it eats animals much larger than insects. It’s been observed eating small birds, especially baby birds, bats, snakes up to 19 inches long, or 50 cm, lizards, and sometimes even other frogs, including poison dart frogs. How embarrassing would that be if you were a bat, with strong wings and the amazing ability to echolocate, and you got eaten by a frog.

When a frog feels threatened, it has several ways to deter potential predators. It can make itself look even bigger by puffing its body up and standing up higher on its legs instead of sitting in a typical frog squat. It also secretes a toxin through its skin, which not only makes it really slippery but also makes it taste awful. It’s not dangerous to humans but can result in a painful burning sensation and rash if the toxin gets into a cut on the skin. If any of the mucus gets into your eyes, they will swell up painfully for hours.

The frog will also give its alarm call if something grabs it. Let’s listen to it again:

[frog ‘screaming’]

During mating season, the male develops little spikes near his wrists and on his chest. This helps him grasp a female without slipping off so he can fertilize her eggs as she lays them. The male uses his back legs to churn up the water and mix it with mucus and sperm to create a foamy nest for the female’s eggs, which protects the eggs from predators and makes sure they won’t dry out. The eggs hatch a few days later, and the tadpoles stay in the nest at first where they eat…well, they eat each other. The tadpoles that hatch first eat the other eggs, and the bigger tadpoles eat the smaller tadpoles. Soon, though, rain washes them out of the nest into open water, where they spend the next month or so eating small insects and algae until they metamorphose into little frogs that live on land. Unlike many frogs, the toes of the smoky jungle frog aren’t webbed since they don’t spend much time in the water.

So many times in this podcast I have to explain that an animal is endangered, so I’m happy to report that the smoky jungle frog is doing just fine. It’s a common animal throughout its range.
