Tigers Make A Triumphant Return To Russia’s Far East, Bringing Hope To The Species’ Future

For the first time, humans have successfully returned orphaned tiger cubs to the wild after raising them and training them to hunt.

For more than 50 years, tigers were absent from Russia’s Pri-Amur region.

Sparsely-populated, mountainous and blanketed in forest, the domain borders the heart of the Russian Far East, offering hundreds of thousands of contiguous square miles for the most robust sub-species of Earth’s most magnificent predator.

Here, tigers can roam without fear of conflict with local farmers, or roads that carve up habitat and pose a danger to animals trying to cross. Prey is abundant, and adaptations for surviving in the local terrain are coded into the tigers’ DNA.

Now that scientists have proven for the first time that tigers can be successfully reintroduced into such an environment, big cat advocates imagine Russia’s Far East as a haven for the large felids. It’s a place where tigers can thrive, mate, reproduce and change the outlook for their species, which has dwindled to only 4,000 or so remaining in the wild.

The project to reintroduce Amur tigers to their native habitat is a cooperative Russian-American endeavor. The team started by building a tiger conservation center in the Amur oblast a decade ago.

The facility is built in a way that orphaned tigers can be raised and taught how to hunt without directly interacting with their human caretakers. That’s a crucial component, because tigers who see humans as potentially friendly or sources of food have drastically reduced chances of surviving in the wild, and are easier marks for poachers.

After 18 months, the cubs are brought to remote locations in Pri-Amur and released. Of the first group of orphan tigers released into the wild, 12 were able to survive on their own.

One gluttonous tiger failed: he crossed over the border into China and began eating domesticated animals, including 13 goats in what researchers called “a single event.”

The fattened tiger then retraced his steps to Pri-Amur, and when he didn’t show fear of humans, the team decided he had to go. They captured him and sent him to a zoo, where he gets all the free meals he wants and contributes to the captive breeding program helping his species maintain genetic diversity.

With 12 out of 13 tiger re-introductions successful, the program provides “a pathway for returning tigers to large parts of Asia where habitat still exists but where tigers have been lost,” said Viatcheslav V. Rozhnov, who leads the reintroduction project.

The successful reintroduction has also led to some surprising developments. Two of the cubs, Boris and Svetlaya, were unrelated but were rescued at about the same time and raised in the Russian orphanage for their species.

Using tracking devices they’d placed on the newly-released young tigers, the research team watched as Svetlaya settled into a home range and Boris made a beeline for her, “almost in a straight line,” crossing 200km (120 miles) of terrain to reunite.

The team’s hopes were confirmed six months later, when Svetlaya gave birth to a healthy litter of cubs, the first natural-born tigers to result from the reintroduction project.

Another tigress, Zolushka, also gave birth to a healthy litter when she was reintroduced in an area closer to a still-extant population of Amur tigers. The researchers believe the father was born wild in the region and was not part of the reintroduction program.

The wilderness in Pri-Amur and its environs is so vast, untouched and undesirable to human habitation that it could be home to generations of tigers, securing their future after so many decades of grim news for the iconic big cats.

“The grand vision is that this whole area would be connected,” Luke Hunter, executive director of the Wildlife Conservation Society’s Big Cats Program. “There’s lots of habitat that could be recolonized by tigers.”

Paleontologists Recover Shockingly Intact Saber-Toothed Kitten Buried For 35,000 Years

The find is extraordinary, allowing scientists to directly study the extinct cat’s musculature, fur, head shape, and even its claws and whiskers.

A team in Russia stumbled on the find of the century when they located the stunningly well-preserved remains of a saber-toothed kitten in Siberia.

The kitten, which was found near the Badyarikha River in northeastern Siberia, was about three weeks old when it died, scientists estimate.

Unlike typical finds — a fang here, a mandible or partial skeleton there — this specimen still had its fur, claws, whiskers and muscles, which means scientists have already learned more about the species, Homotherium latidens, than they have with almost any other long-extinct animal.

While the saber-toothed cub is a true felid, it boasts adaptations unlike any surviving member of the panthera genus.

It has wide paws wrapped in heavy fur, a short tail and a stockier, lower-to-the-ground build than modern lions and tigers. Those adaptations, scientists believe, made it easier for Homotherium latidens to traverse environments with ice and heavy snow.

Its head shape is slightly different, with smaller ears than modern big cats, and its neck is enormous, more than twice as thick as the neck of a comparable three-week-old lion cub which was used for comparison. Likewise, its mouth is capable of opening significantly wider, although the team did not compare it to the jaguar, which has the widest-opening jaw among extant felids.

The frigid, arid clime of Siberia made it possible for the cub’s body to endure for so long. The team that made the discovery conducted radiocarbon dating that puts the cat at between 35,000 and 37,000 years old, according to reports.

It’s not clear how the cub died, although its species went extinct about 10,000 years ago, likely as a direct result of fewer prey animals in the frigid zones it occupied. Additional bones belonging to the rear of the cub skeleton were encased in a large cube of ice immediately next to the intact upper body.

The cub’s remains were recovered in 2020, but the results of the research team’s analysis were just released on Nov. 14 and published in the journal Nature. The paper’s authors have a lot more to share about the species’ physical characteristics, they noted in the text, and plan to follow up soon with a second paper going into more detail about what they learned from the cat’s intact musculature.

Recent News Stories Claim People Have Spotted A Type Of Cat That Doesn’t Exist

It’s easy to mistake house cats for larger wildcats when photos and videos are blurry and lack familiar items to establish a sense of scale. The same phenomenon is responsible for UFO sightings and cryptid creatures like the Loch Ness Monster.

Recently several reports have been making a big deal about blurry videos of black cats, claiming they’re “black mountain lions” or “black panthers” roaming in places like Missouri and Louisiana.

The footage of the first video was shot in Missouri, where pumas once ranged, were extirpated in the 20th century, and have returned in small numbers in recent decades. Like most photos and videos of cryptid or unidentified animals, this one is blurry, taken from a distance, and lacks any object near the animal to provide a sense of scale. The second video is simply a black house cat with her kitten in rural Louisiana.

Our brains are pattern recognition machines and when the information we’re looking for — be it spatial, detail or contextual data — isn’t present, our minds tend to fill in the gaps. That’s the reason why we see faces in clouds, creatures in shadows, men on the moon and the Virgin Mary on grilled cheese sandwiches. (The technical term for “perception imposing meaningful interpretation on a nebulous stimulus” is “pareidolia,” from the Greek for “instead of” and “image.”)

Compounding the problem is the fact that the word “panther” is one of the most confusing of felid descriptors, a word that vaguely refers to physically large cats but doesn’t refer to any particular species, coat pattern or color.

The word panther can refer to a puma, a jaguar or a leopard, but only the latter two species can have melanistic (black) coats.

Contrary to popular belief, even a black cat’s fur is not entirely black — you can still see the rosettes and spots of their coat patterns up close and in certain light conditions.

However, jaguars don’t range in Missouri, leopards are not native to the Americas, and if someone indeed spotted one of the very rare pumas in Missouri, it could not be black because melanistic pumas do not exist.

Mountain lions (Puma concolor in taxonomic nomenclature) are physically large and are the second-biggest cats by size and weight in the western hemisphere after jaguars, but they are not technically “big cats” because they are not part of the pantherinae subfamily. Pumas cannot roar like big cats, but they’re capable of the classic wildcat “scream,” and they can even meow like small cats.

By process of elimination — and the cat’s physical shape — we can conclude the Missouri video shows a house cat that looks larger because there’s nothing nearby to give us a sense of scale.

It may seem unlikely that someone confuses a house cat, which weighs an average of 10 pounds, with a puma, which weighs on average more than 100 pounds, with the largest males pushing 220 pounds.

But it happens all the time even in close encounters, like the incident this summer in which a man riding a dirt bike swore he was ambushed by a puma only for DNA to establish beyond doubt that his attacker was a domestic kitty. For what it’s worth, he still swears it was a mountain lion.

Amazing Cats: The Adorable Colocolo, Feline Of The Pampas

With a perpetual kitten-like appearance and mismatched coat patterns, colocolos may look like the product of AI or Photoshop, but these little ones are very real — and very feisty.

We’re heading back into obscure territory with this edition of Amazing Cats, focusing on a little-known species that ekes out an existence in the forests and plains of South America.

The colocolo, also known as the Pampas cat, superficially resembles the familiar house cat, but a closer look reveals some striking differences.

Colocolos are small, about the same size and weight as felis catus, but their tails can be quite a bit shorter and extremely fluffy.

Colocolo full — Colocolos have pattern and color combinations seen only in their species. This one has rosettes on his body and tabby stripes on his limbs and tail. Some colocolos have thick tails with tabby-like rings, while others have bushy tails more commonly associated with long haired domestic cat breeds.

There are at least five variations of fur color and pattern, ranging from marbled to jaguaresque rosettes and, most strikingly, a seemingly mismatched pattern in which the legs have dark stripes over rusty/cinnamon-colored fur, which contrasts dramatically with the gray, gold, silver or tan of their bodies. The overall effect makes some colocolos look like they’ve been photoshopped, or assembled from spare parts.

Some colocolos appear to have solid-color coats which are actually an agouti pattern with barely visible bands of slightly darker fur.

While the species may look stocky, conservationists say it’s smaller than it appears, with its fur making up the majority of its “bulk.”

Colocolo color variant — This photo might look like a fake, but it’s a documented combination of coat pattern and color among colocolos.

As if that wasn’t enough to distinguish them, Pampas cats have neotenous features that give them an even stronger kittenlike appearance compared to house cats and comparable species like the rusty spotted cat.

In other words, they’re very cute and looking at them can trigger the same protective instincts we feel when we see kittens and cute adult cats. But don’t let their disarming features deceive you — these little guys are not cuddly, don’t respond well to people who get close, and will turn aggressive if you encroach on their space.

Cute colocolo — This adorable colocolo appears to be giving the side-eye to someone. Note the slight suggestion of the classic tabby “M” on the forehead.

While they’re alternately called the Pampas cat, the word “colocolo” comes from the language of the Mapuche, an indigenous group that lived in lands that are parts of modern day Chile and Argentina.

In the Mapuche language, Colo Colo was the name of a Mapuche warrior who led his people in their resistance against Spanish conquistadors in the 16th century, but it’s also the name of an evil rat-like creature in Mapuche folklore. It’s not clear how a feline came to bear the name, but the species — leopardus colocolo — is often called gato colocolo to distinguish between the historical figure and the modern-day Chilean football club, Colo-Colo.

Although they’re associated with the pampa, the flatlands in and around Peru best known for the mysterious Nazca lines, colocolo are adaptable and thrive in forests, jungles, wetlands, and mountain ranges like the Andes, among other terrain.

Their range stretches from Argentina in the south through Chile, Bolivia, Paraguay, Ecuador, western Brazil and an isolated population in Uruguay.

Despite their relatively wide distribution and variety of habitat, colocolos are not well understood. Experts still haven’t settled the question of whether they’re all one species or whether subgroups qualify as their own subspecies. Their hunting habits are not well-documented, although it’s known they prefer small rodents, and there is ongoing debate about whether they are crepuscular, like most felid species, or nocturnal.

Colocolo share a continent with jaguars, pumas, ocelot, jaguarundi, margay, oncilla, kodkod, Geoffrey’s cat and the Andean cat, and the fact that they live in the deep wilderness makes them more difficult to study.

Because their coloration and coat patterns can vary so widely, Pampas cats are often mistaken for other small wildcats living in South America, and people unfamiliar with their species sometimes mistake them for domestic felines.

They’re also very rare in zoos, with only one US zoo (Cincinnati) counting them among their exhibits, and only four Pampas cats in captivity worldwide. (Excluding private captivity by poachers and illegal wildlife traders.)

Like virtually every species of wildcat, the colocolo’s numbers are declining due to a number of factors, primarily human activity like habitat destruction, sport hunting and development cutting populations off from each other.

The more people are aware of these beautiful and little-known felines, the better their chances for long term survival as conservation groups receive more donations to help protect them, and lawmakers are pressured to protect the wilderness where they live.

Yawning colocolo — Like all cats, colocolos appreciate the value of a nice nap.

Amazing Cats: The Sunda Clouded Leopard

Amazing Cats: The Sunda Clouded Leopard

This singular species of wildcat exists only on two islands and has evolved to live a semi-arboreal existence deep in the jungle.

While tigers, lions and domestic cats are the stars of the felid world and command the lion’s share (pun intended) of the attention, even from cat lovers, there are obscure species living in far-off locations where they’re rarely glimpsed by human eyes.

There’s the fishing cat, the black-footed cat and the sand cat, and then there are species that are obscure even among the obscure. The Sunda clouded leopard fits into that category, inasmuch as the unique felid can fit into any category.

Like orangutans, the Sunda clouded leopard can be found in only two places in the world: the Indonesian islands of Borneo and Sumatra. They’re faced with the same existential threat that has pushed orangutans dangerously close to extinction, which is the relentless destruction of old-growth jungle to clear land for more palm oil plantations.

Palm oil is coveted by multinational corporations in the food and cosmetics businesses, and it’s in everything from chocolate and instant noodles to lipstick and margarine, according to the World Wildlife Fund.

The problem with razing old growth jungle and forest is that it doesn’t just grow back. They’re extremely delicate ecosystems that have arrived at a natural balance over thousands of years, with every species of animal and plant contributing something vital to the vibrant tapestry of life the jungles host and support. You can’t just plant trees and usher animals to a new home. It would take hundreds of years for those new jungles to even superficially resemble the lifegiving old growth jungle.

There are heartbreaking images of shocked orangutans sitting in the ruins of their former homes, with nothing but the stumps of trees and dozer-trodden vegetation as far as the eye can see.

Those are the lucky ones. The loggers who work for massive multinational corporations aren’t bound by rules or ethics, and they won’t wait for animals to clear out before they destroy. They often shoot orangutans on sight regardless of whether the animals are carrying young.

That’s the primary reason why Borneo and Sumatra are now home to entire academies for orangutan orphans, who spend at least eight years learning how to fend for themselves with the help of specialists who teach lessons that would normally be taught by the orphan orangutans’ mothers. They include the very basics, like how to move and climb through the jungle, as well as crucial information such as which berries to avoid while foraging.

While there’s no “academy” for clouded leopards and the felids are more adept at avoiding human wrecking crews, they’ve suffered the same fate as orangutans when it comes to dwindling jungles.

This is the situation Sunda clouded leopards find themselves in, so when a trail camera recently captured footage of a mother and her two cubs, conservationists were thrilled.

The footage comes from camera traps belonging to the Orangutan Foundation, and it’s the first time anyone’s managed to obtain video of the Bornean clouded leopards with cubs in tow. The brief video shows the little family bounding through the jungle. They quickly move past the camera, but not before one of the cubs stops to look right at it with typical kitten curiosity.

Sunda clouded leopards are extraordinary cats. Size-wise, they are firmly in the “medium size wildcat” category, with males weighing about 50 pounds. Despite that, they are members of pantherinae, the genus of big cats, having diverged from a common ancestor shared with tigers, leopards, lions and jaguars.

As further proof of their in-between status, Sunda clouded leopards can neither purr nor roar. Typically, each species of felid can do one or the other. Even the species’ scientific nomenclature, neofelis nebulosa, references its intermediate status. (If you encounter alternate taxonomy for them, it’s because the clouded leopards of Borneo and Sumatra are considered distinct subspecies.)

“Due to a different bone structure in their neck, the clouded leopard cannot roar like the larger cats, but also cannot purr because it lacks the fully ossified hyoid bone that allows small cats this ability,” the Smithsonian National Zoo’s keepers explain.

Sunda clouded leopards have several unique adaptations that allow them to thrive in arboreal environments. Their massive tails act as crucial counterweights, allowing them to traverse branches high above the ground without falling. Their paws and paw pads are specialized for gripping tree branches, and their ankles can articulate in ways other felid ankles cannot, allowing the jungle-dwelling wildcats to descend from trees head-first.

Domestic cats infamously lack this adaptation, which is why firefighters are also part-time cat rescuers, coaxing the terrified little ones down from trees, utility poles and rooftops.

The clouded leopards of Borneo and Sumatra are also undeniably cute. People have noticed, which is why one of Google’s auto-complete suggestions for Sunda clouded leopard suggests the word “pet” as an addition. It’s okay to fantasize about having a clouded leopard buddy, but in addition to the fact that they are endangered, they’re also wild animals.

Consider the fact that across the estimated 200,000 years of our species’ existence, homo sapiens have domesticated precisely one felid species, and even that’s not entirely accurate. Felis catus played just as much of a role — and arguably more — than humans did in their own domestication. As predators and obligate carnivores, they are unique among domestic animals, and it took and equally unique set of circumstances to bring cat and man together.

Instead of lamenting the fact that Sunda clouded leopards can’t be pets, we can admire them in the best way possible, from a distance, while helping ensure the survival of this extraordinary, distinctive species by donating to groups like Panthera, the WWF and Global Conservation.
