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

This is our fifth annual updates episode, where I catch us up on new studies published about various animals we’ve talked about before. This is mostly just whatever happens to catch my eye and isn’t comprehensive by any means. Also, because things have been so busy for me the last few weeks, I decided to just go with what I’d already finished and not try to add more.

We’ll start as usual with corrections, then do some updates, then learn about a parrot from New Zealand, which was a suggestion from Pranav. This part of the episode started as a Patreon episode from 2019, so patrons, I promise your October bonus episode will be brand new and interesting and in-depth!

First, both Llewelly and Zachary pointed out that there are lions living in Asia, not just Africa. It’s called the Asiatic lion and these days, it only lives in a few small areas in India. It’s a protected animal but even though their numbers are increasing, there are probably still no more than 700 Asiatic lions living in the wild.

Next, Nicholas points out that vitiligo isn’t a genetic condition, it’s an autoimmune disorder that can be caused by a number of different diseases and conditions. You still can’t catch it from other people, though. We talked about vitiligo briefly in episode 241, about squirrels. Nicholas included a link, which I’ll put in the show notes for anyone who’s interested in learning more.

For our final correction, Simon questioned whether there really are only six living species of macaw known. This was polite of him, since I was completely wrong about this. In fact, there are six genera of macaws and lots of species, although how many species there are exactly depends on who you ask. Since this mistake made it into the Beyond Bigfoot & Nessie book, I am very irritated at myself, but thank you to Simon for helping me clear this up.

Let’s start our updates with the animal who gets an update every single time, Tyrannosaurus rex. A study published in February 2022 examined the fossilized remains of 37 T. rexes and suggested that there may actually be three distinct species of T. rex instead of just one. The study focused specifically on differences in teeth and leg bones that don’t seem to have anything to do with the individual’s age when it died or whether it was male or female.

However, in July 2022, another study found that all the T. rexes found so far do indeed belong to the same species. This is how science works, because new information is always being discovered and that means we have to reassess the things we thought we knew.

In other dinosaur news, in episode 240 we talked about the last day of the dinosaurs. Results of a study released in February 2022 suggest that the asteroid struck in early spring in the northern hemisphere. The asteroid hit the earth so hard that it rocked the entire continental plate that it struck, which caused massive waves unlike any other waves, since all the water above the continental plate was pushed upwards at once. This pushed all the sediment lying quietly on the bottom of the ocean up into the water, so much of it at once that it actually buried a lot of fish alive. The same thing happened in lakes and every other body of water. The fossil site we talked about in episode 240 is still being studied, the one that appears to date to literally the day of the asteroid impact, and preserved soft tissues in some of the fish have been discovered. Careful analysis of the fish show evidence that they all died in early spring. Researchers suggest that the time of year may have been especially bad for many dinosaurs, who were probably just starting to lay eggs and have babies.

In even more recent last-day-of-the-dinosaurs news, in August 2022 a study was released about a newly discovered crater off the coast of West Africa. Researchers are pretty sure it was from an asteroid impact, although much smaller than the big one that hit what is now Mexico and led to the extinction of all non-avian dinosaurs. They’re also not completely certain when it formed, since it’s deep under the sea floor these days and was only discovered when scientists were examining seismic survey data of the sea floor. But it does seem to have formed about 66 million years ago, and another crater found in Ukraine is also about the same age. In other words, there may have been more than one asteroid that hit earth at the same time, either because a bigger asteroid broke into pieces as it entered earth’s atmosphere, or because smaller asteroids were orbiting the bigger one.

We’ve talked about the monarch butterfly several times, especially in episode 203. The monarch is a beautiful orange and black butterfly that migrates from the United States and Canada into central Mexico for the winter, where it gathers in huge groups. The monarch butterfly caterpillar primarily eats the milkweed plant, which contains toxins that the caterpillar stores in its body. Those toxins remain in the body even after the caterpillar has transformed into a butterfly, meaning the butterflies are toxic too. Birds and other animals learn to recognize the bright orange and black pattern of the butterfly and avoid eating it, because it tastes bad and makes them sick.

But a study from December 2021 determined that one animal does eat monarch butterflies, and a whole lot of them. Many species of mouse that live where monarch butterflies spend the winter, in a few spots in Mexico and California, will eat the butterflies, especially ones that fall to the ground either by accident or because they’re unhealthy and weak. The mice show resistance to the butterfly’s toxins.

Research into the small hominin remains on the island of Flores is ongoing, and the most recent findings shed some light on what might have happened about 60,000 years ago. The so-called Hobbit fossils have all been found at Liang Bua, a giant cave, but lots of other fossils have been found at the same site. A whole lot of those are from various species of rodent, especially rats, ranging in size from mouse-sized to ordinary rat-sized to giant rat sized, over two feet long including the tail, or about 75 cm.

Because we know a lot about the rats that lived on Flores, and in some cases still live there, we can infer a lot about what the area around Liang Bua was like over the centuries. Until about 60,000 years ago, most of the rat remains found were of medium-sized species that like open habitats. That means the area around Liang Bua was probably pretty open. But after about 60,000 years ago, there’s a big shift in what kind of rodents appear in the fossil record. More rats of smaller size moved in, ones that were adapted for life in forests, while the medium-sized rats moved out. That corresponds with other animals disappearing from the fossil record in and around the cave, including a species of Komodo dragon and a subspecies of Stegodon, an elephant relation that exhibited island dwarfism and was about the size of a cow. The Flores little people remains also vanish from the cave during this time, until by 50,000 years ago there are no signs of them.

But that doesn’t mean that H. floresiensis went extinct at that time. Researchers now think that as the land around the cave became more heavily forested, the Flores little people moved to other parts of the island that were more open. We don’t know where yet, and as a result we don’t know when exactly they went extinct. They might even have left the island completely. One neighboring island is Sulawesi, and researchers have found small stone tools on that island that are very similar to those made by H. floresiensis.

Modern humans probably arrived on the island of Flores about 46,000 years ago, and it’s possible that when they did, their small-statured cousins were still around.

We’ll finish with Pranav’s suggestion, a New Zealand parrot called the kea!

The kea is a type of parrot, but it doesn’t look much like a parrot at first glance. Parrots usually have brightly colored feathers but the kea appears more drab initially. It’s olive green with black-laced feathers, but it has bright orange feathers under its wings that show when it flies and the tips of its wings are blue. It’s a big, heavy bird with a wingspan more than three feet across, or one meter, and it has a big hooked beak like other parrots. It lives in the mountains of New Zealand’s South Island, the only parrot that lives in such a cold environment.

The kea is an omnivore but it mostly eats plants and insects. It will eat roadkill, small animals like rabbits, chicks of other species of bird, and trash. For over a century there were rumors that the kea would attack sheep, which led to the New Zealand government paying a bounty for dead keas that wasn’t lifted until 1970. By the time the bounty ended, there were only around 5,000 keas left, and even then the bird wasn’t fully protected until 1986.

So does the kea kill sheep or was that just an excuse to kill birds? Actually, the kea does attack sheep, or at least some keas do. Most of the attacks aren’t fatal, but we definitely know it happens because someone got it on video in 1992.

The keas land on the sheep’s back and pull out hunks of wool, which exposes and injures the skin underneath. Then they use their sharp beaks to dig into the wound and eat the fat from the living sheep. This can result in the sheep dying from infection and shock, naturally, so it’s no wonder sheep farmers disliked the kea. But the sheep is not an animal native to New Zealand while the kea is, plus the kea primarily eats plants—and sheep destroy the plants the kea eats, especially the ones high in vegetable lipids that provide the same high energy food that sheep fat does.

Besides, there’s some tantalizing evidence that the kea used to do the same thing to the moa, a huge flightless bird that lived in New Zealand until it went extinct after humans arrived. Moa bones dating to 4,000 years ago and found in a swamp along with lots of other well-preserved bones show markings on the pelvis that may be from kea beaks.

Like other parrots, the kea is remarkably intelligent and known for its tool use. It’s also infamous for its curiosity and willingness to disassemble things, including cars. I found an article about the kea in New Zealand Geographic that has some awesome stories about the bird, like this one that I’ll quote.

“In September 1983, the Old Pompolona Hut on the Milford Track was destroyed by flood when the pent-up Clinton River broke through its winter avalanche dam. The walking track season was only six weeks away. Planners, builders and helicopter crews worked night and day to complete a new hut complex before the first walkers arrived.

“The local clan of kea took a keen interest in all this frantic activity after a cold and quiet winter. Just what were these people up to? One bird, for whom building materials seemed to hold a particular attraction, began stealing nails. So persistent was the bird’s thievery that an exasperated carpenter chased it (in vain) over the roof of the new main hut. While his back was turned, another kea stole his packet of roll-your-owns, shredding tobacco and papers to the raucous approval of spectator kea perched in nearby trees.

“Weeks later, after the new hut had been completed, the purloined nails were discovered. They had been neatly laid in the gutters of an outbuilding’s iron roof, sorted according to size.”

The kea’s intelligence, tool use, and problem-solving abilities line up with those in corvids like crows and ravens. Studies show that corvids are more successful figuring out tasks that require them to make pecking motions in one way or another while parrots, including the kea, are more successful when the tasks require pulling motions. This makes sense, since parrots have a hooked beak that they use to pull things apart, like rotting logs to get at grubs, while corvids have straight beaks that they use to stab through things to find food.

The kea is also really sociable. Young keas play together, often using items as toys. For instance, from the same article, witnesses at a ski resort watched a kea steal a plastic mug, fly off with it, and start up a game of catch with it with a group of other keas.

The kea even has a particular call it makes to encourage other keas to play. In a recent study, when the call was broadcast to some captive keas over a loudspeaker, the keas immediately started a game of chase. Researchers think the call isn’t so much an invitation to play but is more like laughter which makes other keas want to laugh along, or in this case play.

This is what the play call sounds like:

[kea call]

The kea builds its nests in burrows it digs in the ground, with some burrows 20 feet long, or 6 meters. The nesting chamber is lined with soft plant material. Females lay two to five eggs, which hatch in about three weeks. Despite the parents’ care, more than half of babies don’t survive their first year, mostly due to introduced predators like rats, stoats, and possums. But if a kea survives to grow up, it can live up to 50 years or possibly more.

Young keas, like young adult humans, can cause a lot of mischief that sometimes leads to tragedy. A lot of keas are killed by cars because they find cars and roads interesting. They especially like to move road cones, which of course is also dangerous to humans. One community set up a kea jungle gym well off the road to give keas a safe place to play, and it succeeded so well that other communities have built kea jungle gyms too.

Kea numbers are improving slowly, with an estimated 7,000 individuals alive today. Part of the problem is that keas find humans interesting. They like our things, which they want to steal or destroy, and they like our junk food, which they want to eat. In other words, they’re suspiciously like us. Only they can fly.

Show transcript:

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

This week I had planned to release our updates episode, but I didn’t have time to finish it. The 2022 updates episode will run in September instead, since we’re doing Invertebrate August again this year!

Way back at least a year ago and possibly more, Vaughn suggested we do an episode about “rare two-tone animals like Venus the cat.” I put the suggestion on my list and totally forgot about it until today, when I saw it and thought, “hmm, who’s Venus the cat?”

If you don’t already know, Venus is a beautiful cat whose coloration is mostly what’s called tortoiseshell, meaning she has a mixture of colors on her body, in her case black and orange. But Venus’s face is completely black on one side with a green eye, but orange tabby on the other side with a blue eye. She also has a white bib and white on her paws.

Venus became famous after the family who adopted her as a stray in 2009 posted pictures of her online. Her coloration is so unusual that everyone wondered what caused it. The answer is that we aren’t exactly sure, but veterinarians and experts in cat genetics do have some pretty good ideas.

There are probably several things going on genetically with Venus that resulted in her interesting coloration. Her different-colored eyes are one result. When an animal has different-colored eyes, called heterochromia iridis, there are a number of possible causes, from an injury to one eye to various genetic conditions. Sometimes it’s not complete, meaning one eye may be partly a different color. It even happens in people sometimes, although it’s rare.

In Venus’s case, researchers think her heterochromia may be due to a gene that produces what’s called piebaldism. A piebald animal has white markings when an ordinary animal of the same species doesn’t have any white markings. Some animals who naturally have a white pattern may have the word pie or pied or just bald hidden in their name, such as the magpie and the bald eagle, because it used to mean just an outfit with different contrasting colors. In the story of the pied piper, the piper had on a suit made of different colors.

The white patches of a piebald animal actually don’t have any pigment, and if a white patch is over an eye, the eye may also lack pigment and appear blue. That’s pretty common in piebald or pinto horses or in some dog breeds with white markings. The piebald gene may also affect one or both eyes even if a white patch doesn’t cover the eye, which some researchers think may be the case in Venus. Her left eye is blue even though the left side of her face is orange tabby.

Venus’s unusual facial fur coloration may be due to a condition called chimerism. Chimerism happens long before an animal is born—in fact, it happens within a few hours after an egg cell is fertilized. I’ll do my best to explain it. A lot of the next section comes from a Patreon episode from 2018, and if you want to listen to the original I’ve unlocked it for anyone to listen to and put a link in the show notes.

As soon as an egg cell is fertilized, it starts to divide into more cells, which divide into more cells, which divide into more cells, and on and on. After a while, the groups of cells start to differentiate into parts of the body. Some cells become a heart, others become toes, and so on. Eventually there’s a whole finished baby ready to be born or hatched.

If there are two fertilized egg cells, they develop into two separate babies, which are fraternal twins that don’t necessarily look alike. Occasionally, a fertilized egg cell will split and each of the two resulting cells will start to develop separately. In that case, you get identical twins.

But very rarely, you start with two egg cells that should develop into fraternal twins—but for some reason, in those very first hours when each egg cell has only divided a few times, the egg cells fuse together. The cells continue to divide and develop into not two babies, but one that contains the genetic markers for both twins.

Since the resulting single baby has genes for both twins, sometimes it will show physical traits of both twins. For instance, if one twin’s genetic makeup would have developed into a green budgie, and the other twin’s genetic makeup would have developed into a blue budgie, you get a budgie that’s green on one side and blue on the other. Occasionally one side has the markings and coloration of a male, and the other side has the markings and coloration of a female. An animal with this kind of genetic anomaly is properly called a tetragametic chimera, but it’s often called a half-sider.

This doesn’t just happen in birds. Occasionally someone will come across a butterfly where the pair of wings on one side is colored like a male of that species and the pair of wings on the other side is colored like a female. Occasionally someone will adopt a kitten that’s one color on one side and a totally different color and pattern on the other side.

So I bet now you’re wondering if it happens in humans. Yes, it does! It happens occasionally in everything, including plants. Usually no one knows if a particular animal is a chimera because most of the time it doesn’t show. It’s only when it produces a spectacular coloration difference like in half-siders that anyone takes a second look.

Venus’s facial markings look a lot like those of a half-sider, but the markings on the rest of her body don’t, so she’s probably not a half-sider. That doesn’t mean she isn’t a chimera, since while all half-siders are chimeras, not all chimeras are half-siders. However, she might have a genetic mutation called mosaicism instead.

Mosaicism is similar to chimerism, but instead of being caused by two fertilized egg cells fusing together, it’s caused by a chromosomal mutation in one cell during the embryo’s very early development. The mutation is replicated as that cell divides, and then replicated in the divided cells, and so on, so that when the organism has finished developing into a baby, part of its body contains the mutation while the rest doesn’t. The part of the body with the mutation has a different genetic profile from the rest of the body.

Mosaicism can result in various physical conditions, but for the most part you can’t tell by looking if an organism exhibits mosaicism. But sometimes you can. In 1975 a lion cub was born in Glasgow Zoo in Scotland, and he had a big black patch on his chest and right front leg, with a less dark patch on his left hind leg. Since black lions are rumored to exist but have never been scientifically documented, or even photographed, this was a big deal. When Ranger the lion grew up he was introduced to several different females in hopes that he would sire cubs that also had black patches, or which were even black all over. Unfortunately Ranger seemed to be sterile and none of his mates got pregnant.

Ranger lived to be 22 years old but died before genetic testing became widespread and sophisticated. These days we know a lot more about big cat genetics and researchers are pretty sure Ranger’s black patches resulted from somatic mosaicism, which affected some of his skin cells. Since the right side of Venus’ face is solid black, some researchers think she might have a similar condition.

Whatever the cause or causes of Venus the cat’s coloration, though, one thing is for sure. She’s an absolutely beautiful cat!

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

This week we’re going to learn about some mystery big cats. We’ve touched on big cats before in various episodes, including the British Big Cats phenomenon in episode 52. We’re definitely going to see some more out of place animals this week, along with lots of information about big cats of various kinds. Thanks to Damian who requested an episode about lions and tigers ages ago.

I’ve also unlocked three Patreon episodes so that anyone can listen to them. They won’t show up in your feed, but there are links in the show notes and you can click through and listen on your browser without needing a patreon login. The first is about marsupial lions and the second is about blue tigers and other big cats with anomalous coat colors. The sound quality on the blue tigers episode is not that great, but it’s a long episode with lots of information about blue tigers, white tigers, black tigers, white lions, king cheetahs, and lots more. The third is about the Queensland tiger, an Australian animal that’s not a feline of any kind, but why not?

The term big cat refers to tigers, lions, leopards, snow leopards, and jaguars, but it can also include cheetahs and cougars depending on who you ask. Big cats have round pupils instead of slit pupils like domestic cats and other smaller cats.

Lions, tigers, leopards, and jaguars can all roar. Snow leopards, cheetahs, and cougars can’t. But snow leopards, cheetahs, and cougars can purr, while lions, tigers, leopards, and jaguars can’t. The ability to roar is due to special adaptations in the larynx, but these adaptations also mean big cats can’t purr. So basically a cat can either roar or purr but not both.

The word panther, incidentally, refers to any big cat and not to a specific type of animal. So a black panther, in addition to being an awesome movie, is any kind of big cat exhibiting melanism, which causes the animal’s fur to be black all over. Leopards and jaguars are most commonly referred to as black panthers. Lions, tigers, and cheetahs do not exhibit true melanism as far as researchers have found.

Let’s start with lions. Lions live only in Africa these days, but were once common throughout parts of southern Asia too and possibly even parts of southern Europe. The lion is most closely related to the leopard and jaguar, less closely related to the tiger and snow leopard, but it’s so closely related to all those big cats that it can interbreed with them in rare cases.

There are two species of lion, the African and the Asian. Until recently there were also several subspecies of African lions, including the American lion, which once lived throughout North and South America. It only went extinct around 11,000 years ago. The American lion is the largest subspecies of lion ever known, about a quarter larger than modern African lions. It probably stood almost four feet tall at the shoulder, or 1.2 meters. Cave paintings and pieces of skin preserved in caves indicate that its coat was reddish instead of golden. It lived in open grasslands like modern lions and even in cold areas. There are reports of a reddish, short-maned cat supposedly called a “jungle lion” sighted in South America, but I can’t find much information about it and it’s much more likely to be a jaguar or cougar than a relic population of American lions. But wouldn’t that be awesome if it was.

The Barbary lion was a subspecies of African lion that lived in northern Africa until it was hunted to extinction. The Barbary lion was the one that battled gladiators in ancient Rome and was hunted by pharaohs in ancient Egypt, a big lion with a dark mane. The last one was supposedly killed in 1922, but recent research indicates that they survived much longer—maybe as late as 1958 or later. The last recorded sighting was in 1956, but the forest where it was seen was destroyed two years later.

One zoo in Morocco claims that their lions are purebred Barbary lions, descended from royal lions kept in captivity for centuries. But since we don’t have a full genetic profile of the Barbary lion to start with, it’s hard to determine whether the royal lions are Barbary lions. So far a 2005 DNA test on five of the royal lions indicates they probably aren’t, but DNA testing has come a long way since then and new tests on the royal lions and on preserved Barbary lion skins will hopefully be done soon.

The Sumatran golden lion, also called the cigau [pronounced chee-gow] is a mystery lion that is supposed to be golden in color with no markings, a relatively short tail, and with a mane or ruff of fur that’s sometimes described as white. It’s only about the size of a small donkey or large goat, but stocky like a lion. The most recent sightings are from the 1960s, where one supposedly attacked and killed a man. Some researchers think it may be a subspecies of the nearly extinct Asiatic lion, but others say it’s more likely to be an animal of folklore. Then again, there are tigers on Sumatra and it’s always possible it’s an anomalous coated tiger with no stripes, or stripes that are almost the same color as its coat. Tigers do have a white ruff around the face.

Lions are well known to live on the savanna despite the term king of the jungle, but they do occasionally live in open forests and sometimes in actual jungles. In 2012 a lioness was spotted in a protected rainforest in Ethiopia, and locals say the lions pass through the reserve every year during the dry season. That rainforest is also one of the few places left in the world where wild coffee plants grow. So, you know, extra reason to keep it as safe as possible.

Let’s talk about tigers next. Tigers are awesome animals, with the Bengal tiger being the biggest big cat alive today—on average even bigger than the lion. Tigers are good swimmers and most really like the water, unlike most cats. They live throughout Asia but once were much more common and widespread. I’ve found a lot of mystery tiger reports, but if you’re interested in tigers of unusual colors, I really do recommend you go listen to the unlocked Patreon episode about blue tigers.

The so-called beast of Neamt is a modern mystery from Romania. In spring of 2016, farmers started finding livestock killed during the night, but not eaten. The predator was clearly extremely strong, much stronger and larger than a dog. Its method of killing didn’t suggest a bear, which locals were familiar with anyway.

Some of the sightings seem normal, of a catlike animal the size of a calf. Other sightings were more bizarre. Some people reporting seeing a huge animal running on two legs, one guy said he’d wounded it with an axe but it didn’t bleed, and of course there were the predictable reports that animals it killed were drained of blood.

But in this case, DNA testing solved the mystery of what was killing the animals. The beast was injured by a barbed-wire fence, and a test of its blood indicated it was a Siberian tiger. The Siberian tiger is also called the Amur tiger, which we talked about in episode 44, Extinct and Back from the Brink. But there are probably no more than 500 Siberian tigers alive in the wild, and none of them live within 3,000 miles of Romania, or 5,000 km. So while we know what the beast of Neamt is, we don’t know how it got there. Out of place tigers, hurrah!

Another mystery tiger is from Chad in Africa. This one is sometimes called the mountain tiger, and it’s supposed to be the size of a lion but with reddish fur, white stripes, no tail, and huge fangs.

This doesn’t sound like anything alive today—but it does sound like an extinct cat called Machairodus. It was the size of a lion, or over 3 feet tall at the shoulder, or 1 meter, and around 6 ½ feet long, or 2 meters. It was a type of saber-toothed cat like Smilodon, although it wasn’t closely related to Smilodon and its fangs weren’t as big. It probably had a short tail. But Machairodus and its relatives died out probably a million years ago, although it might have persisted to only 130,000 years ago. That’s still a lot of years, so it’s not too likely that a population of its descendants still lives in Chad. For one thing, northern Chad is part of the Sahara, while southern Chad is a savanna. It’s not dense jungle or remote mountains.

But there are similar reports of the mountain tiger in other parts of Africa, where there are steep mountain ranges that aren’t well explored. And, oddly enough, similar reports also come from South America and even from Mexico. Machairodus did live in Africa, Eurasia, and North America, although its fossils haven’t been found in South America. Maybe the reports aren’t of a living animal but were inspired by fossil remains. Hunters who stumbled across fossil machairodus bones would recognize them as similar to tiger or lion skeletons, but wouldn’t know that the living animal was long gone.

Another South American big cat report comes from Ecuador. It’s called the rainbow tiger or rainbow jaguar, and it sounds really pretty. In the Macas region in southeastern Ecuador, in the Amazon jungle, locals have a story about a big cat properly called Tshenkutshen. The cat is the size of a jaguar, or up to six feet long not counting the tail, or 1.85 meters, but instead of having a pattern of dark rosettes on a tawny background coat, the rainbow tiger is black with stripes on its chest. The stripes are different colors: white, red, yellow, and black, which gives it the rainbow name. One report I saw says it’s white with black spots in addition to the stripes on its chest. It lives in the trees in remote areas, is rare, and at least one report says it has a hump on its shoulders and monkey-like forepaws but with claws. One was supposedly shot and killed in 1959, but there are no pictures of the carcass and no one knows where it went, if it even existed in the first place.

Naturally, the rainbow tiger isn’t actually a tiger since tigers don’t live in South America. If it is a real animal and not a folktale, it’s probably a type of jaguar. But the whole monkey hands thing implies it’s probably more of a mythological creature than a flesh and blood one, because no feline of any kind has forepaws that resemble hands.

There’s an interesting addition to the rainbow tiger mystery. Dutch primatologist Dr. Marc van Roosmalen spotted a strange jaguar during an expedition through Brazil in the late 1990s. It was mostly black, but had a white pattern around its throat.

There are plenty of other South American big cat mysteries, including the yemish that we covered in episode 59 along with the onza, a mystery cat from Mexico and central America. But one especially interesting report is from Peru. Peter Hocking is a Peruvian ornithologist, or someone who studies birds, but he’s also interested in other animals. In 1996 he got his hands on two skulls that were similar to jaguar skulls but reportedly not from jaguars, but from strange striped big cats instead.

In 2010, zoologist Darren Naish asked for and finally received high-quality plaster replicas of the skulls so he could study them. His conclusion is that both skulls are actually from jaguars, but he points out that most big cat species do occasionally produce anomalously striped individuals. No one knows where the pelts of these two jaguars are, unfortunately. Hopefully they’ll turn up eventually, or another striped jaguar will be found and can be studied so we can learn if it’s just an individual with an anomalous coat pattern, or an actual subspecies of jaguar with stripes instead of spots.

I couldn’t find any mystery cheetah reports beyond one called the Tennessee red cheetah. That excited me because I live in Tennessee and I’d never heard of it before. The Tennessee red cheetah is supposed to resemble the cheetah, golden brown with black spots, but with a reddish dorsal stripe and tail. Some reports say it’s reddish-brown all over with black spots.

That’s it. That’s all the information I can find. I was so disappointed, but basically it sounds like a tall tale or maybe a sighting of a jaguar. That’s the problem with mystery big cat reports. There are so many reports of so many animals that don’t correspond to any known species or subspecies of big cat, with few concrete details. In the case of the Tennessee red cheetah, the only details I could find were vague stories about one being shot and skinned, but the skin was missing. No date, no place, no names, nothing.

You can’t treat a report like that with anything but skepticism, so let’s move on to another mystery big cat, the Zanzibar leopard. When I was making notes for this episode, I wrote “probably extinct, may be too depressing to use.” But there’s always a chance it’s not extinct.

The Zanzibar leopard lives on Zanzibar Island off of Tanzania. It’s not a big island, only around 50 miles long, or 85 km, and 20 miles wide, or 30 km. The Zanzibar leopard was probably separated from the mainland population of leopards when sea levels rose after the last ice age. It’s smaller than a mainland leopard, with smaller spots, but not much is known about it since it hasn’t been studied in the wild and it may be extinct now. Unfortunately, many people on the island believed that the leopards were witches’ familiars, and that they should be killed. In 1964 the islanders overthrew the government, but also unfortunately, the newly installed government persecuted people it decided were witches. This included a government-run campaign to kill all leopards on the island. By the mid-1990s, conservationists suspected the Zanzibar leopard was extinct.

But there is hope. Earlier this year an Animal Planet show caught footage on a camera trap of what appears to be a Zanzibar leopard. Hopefully there are still some of the leopards remaining, and if so, hopefully they can also be protected.

Speaking of Tanzania, let’s finish with a big cat that might very well be a real animal—or something even more mysterious. The nunda is supposed to be a huge gray cat with tabby stripes, reported in Tanzania. Its paw prints are supposed to resemble a leopard’s, but are as big as a lion’s.

In a 1927 article, a British administrator named William Hichens reported about his investigation into nunda attacks around the village of Lindi in Tanzania. The attacks occurred in 1922, and started with a night watchman who was found dead one morning. Clutched in the dead man’s hand was a tuft of gray fur that Hichens thought might have been torn from a lion’s mane. But lions were rare in that part of Tanzania, and two locals reported seeing a huge brindled cat attack the man during the night. A few nights after that, another watchman was also killed in the same way, including the tuft of hair clutched in one hand, and that was followed by more attacks in other villages over the next several weeks. The attacks stopped, but resumed in the 1930s. Some huge footprints and more of the gray fur were found by a British hunter who tried to track the animal.

So what might the nunda be? The description doesn’t sound like any known big cat. Cryptozoologist Bernard Heuvelmans suggested it might be a huge African golden cat with anomalous markings. The African golden cat is related to the caracal and the serval, both fairly small, long-legged cats. It has variable markings and coloring, from reddish to grey, from spotted to nearly plain. But it’s only about twice the size of a domestic cat. Its paws are large for its size, but it’s not anywhere near the size of a leopard, much less a lion.

Of course, it might be a larger subspecies of golden cat, or a totally different species. But there is another possibility, one that’s far creepier and darker than an unknown big cat.

According to a book called Wild Cats of the World by Mel and Fiona Sunquist, published in 2012, in the early 20th century a group of witch doctors in that part of Tanzania ran an extortion racket. They demanded money from people and threatened to turn into lions and kill them if they didn’t pay up. And they did kill people—over 100 of them, according to the book. The murders were committed by young men who dressed like lions, including wearing lion paws on their feet so they left lion paw prints.

That would explain the rash of murders in a localized area, and the fact that so many of the victims were found clutching gray fur. The fur was never tested and could have come from any animal and been planted on the victims.

Zoologist Karl Shuker suggests that if the deaths weren’t due to these lion-men, the mystery big cat might be a type of leopard with stripes instead of spots. Leopards with stripes due to genetic coat anomalies are extremely rare, but they aren’t unheard-of. They’re sometimes referred to as king leopards. I have a picture of one in the show notes. While leopards can cross-breed with tigers, tigers don’t live in Africa, so a striped leopard-tiger hybrid wouldn’t be hanging around in Tanzania, certainly not in the 1920s.

Whatever the cause, no one has reported a nunda sighting in about 80 years.
