How Four Wildcats Co-Exist In The Jungles Of Guatemala

Jaguars, pumas, ocelots and margays are able to thrive in the same jungles, a unique arrangement that sheds light on how each species lives.

The jungles of Guatemala are teeming with life.

The guttural calls of howler monkeys haunt the rainforest from above, where scarlet macaws hop branches in flashes of red, yellow and blue.

On the forest floor opossums, peccaries, and oversize rodents called pacas move through dense brush, occasionally picked out by the few shafts of light able to break through the canopy. Ocellated turkeys plumed in iridescent copper and emerald advertise themselves to potential mates with thumping sounds, while spider monkeys perch on the weathered stones of long-forgotten Mayan cities that were swallowed by the jungle centuries ago.

As in most tropics, the apex predators are cats — four different species, to be exact. Jaguars sit at the top, unchallenged. Pumas, close in size if not ferocity, also find sustenance in the rainforest alongside ocelots and margays.

The felids hunt at different levels of the jungle at different times of day, and while there’s overlap between prey, each species has its own distinct diet, according to a research team from Oregon State University. Their paper, Niche partitioning among neotropical felids, was published earlier this month in the Journal of Animal Ecology.

As the big kids on the block, jaguars primarily eat peccaries (pig-like ungulates that weigh up to 88 pounds), armadillos, deer and, sadly, ocelots. Apparently membership in Club Felid does not grant the smaller wildcats a pass. Ocelots top out at about 35 pounds, while the largest jaguars weigh in at about 350 pounds, making the smaller cats easy prey.

Pumas opportunistically prey on peccaries and brocket deer, but the majority of their diet is composed of monkeys, both spider and howler. Ocelots and margays naturally go for smaller prey, sticking mostly to rodents and opossums.

While jaguars hunt on the ground and have a well-documented habit of slipping into the water to prey on caiman and crocodiles, pumas, ocelots and margays take advantage of their climbing abilities and lighter frames to reach arboreal prey. That allows pumas, for example, to snag monkeys and arboreal opossum species from the canopy, so they don’t have to compete with jaguars.

The team verified the “spatial, temporal, and dietary niche partitioning” within the Maya Biosphere Reserve by using ground camera traps, arboreal camera traps and fecal samples, which allowed them to confirm the prey each species has been consuming.

Interestingly, margays are the pickiest — or perhaps most limited — of the bunch, preying on only seven species, while the other three cats regularly hunt between 20 and 27 different kinds of animals.

The information gleaned from the study not only helps researchers understand how these species interact with their environment, but also can help guide conservation decisions to safeguard them against extinction.

Wordless Wednesday: The Glorious Amur Tiger

Today we’re admiring photos of the majestic Amur (Siberian) tiger, a species that has been pulled back from the brink of extinction thanks to the hard work of conservationists.

The Amur tiger, panthera tigris altaica, is the largest subspecies of the largest cat in the world.

Facebook Is Flooded With Hoax Posts About A Supposed Black Mountain Lion

The purveyors of the deceptive posts want you to click, share and argue with other users about the veracity of the photos.

Not only is he the rarest puma in existence, he’s more well-traveled than most humans.

The mountain lion in question has a black coat, unprecedented for his species, and has been popping up all over Facebook. He’s photographed from the passenger seat of a truck cab, his tail in an unbothered curl, crouched amid the brush near a rural road.

Some posters claim they spotted the formidable feline in Mississippi. Others attribute the image to a sister-in-law who lives near Houston or a daughter in Charleston. A user in Louisiana claimed they took the photograph near the bayou, while another places the cat in Wyoming and claims he’s the first-ever documented “shadow cougar.” (Our friend Leah of Catwoods drew our attention to the images last week after seeing posts placing the cat in the south.)

In case it isn’t obvious, all the claims are full of it.

There is no such thing as a melanistic (black) mountain lion, and the big cat in the photo has the physical characteristics of a leopard, an animal that is not native to this hemisphere, let alone this continent.

The real story here is that Facebook remains a fountain of misinformation and Meta (its parent company) doesn’t care. Unscrupulous users will do anything to get attention and the clicks that come with it, and the average Facebook user is happy to indulge them, driving clicks by resharing the hoax content and juicing its algorithmic value by engaging in endless arguments with fellow users about the veracity and provenance of the photos.

Alleged big cat sightings are perfect for this sort of thing because they pique people’s natural curiosity, there’s a whiff of danger — especially when the poster claims the animal was spotted locally — and most people aren’t aware of telltale differences between cat species.

In many ways, the blurrier and more indeterminate the photo, the better: like Bigfoot and the Loch Ness monster, the idea of phantom cats is most fertile in the imagination.

These days you don’t even need a photo to get in on the click-baiting action. I asked Gemini to create an image of a jaguar-like big cat walking along a rural road at night, and this is what the LLM gave me:

In the image prompt, I asked it to make it look like an amateur photo taken with a midrange smartphone camera, but if we really wanted to get artistic, it’s simple enough to add noise, maybe some motion blur and digital artefacts to the image to make it look more like an authentically crappy, rushed shot of an unexpected animal.

Here’s the result of some simple efforts to en-crapify the “photo” further:

To give the image urgency and encourage people to engage with it, I can make it local and claim it was recent. Errors of grammar, spelling and punctuation add a nice seasoning of authenticity, along for feigned concern for others as the reason for sharing:

“Folks – just wanted to tell ya’ll to mind your pets an make sure of you’re surroundings bc theres a big cat on the lose!! my cousins GF took thus friday nite on Route 9 a few mile’s south of Dennies. a real honest to goodness black panther! BE SAFE!!!”

There’s a dangerous animal on the loose in your area! You know what you have to do: share it so others can bring their pets safely inside and stop their kids from playing outdoors, at least until it looks like the predator has moved on.

It’s your duty as a good American!

Since it doesn’t seem to matter if a quick reverse image search can settle the question of where an image came from, it’ll be interesting to see if anyone lifts the above image and text.

At the very least, maybe a few people who do think to run a search will find their way here, read about the hoax, and save themselves from getting drawn into online debates about the existence of cryptid cats.

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.

‘Best Video Of A Lynx We’ve Ever Captured’: Wild Cat Shows Off For Camera

The trail camera is operated by a team studying the behavior of wolves, but this felid became the main character for a short while, posing majestically right in front of the lens.

Happy Monday! We’re starting the week off in style with an amazing video courtesy of the Voyageurs Wolf Project.

As its name implies, the project is a collaboration between wildlife biologists, ecologists and academics to learn more about wolves, specifically how they survive in the summer months.

While there’s a wealth of research on the behavior of wolves during winter, the pack animals go their separate ways in the warm weather to raise newborn cubs and hunt smaller prey.

Because it’s much more difficult to track individual wolves under the cover of heavy brush compared to following entire packs in the snow, the project relies on a combination of GPS collars and trail cameras. The latter pick up all sorts of wildlife in the Minnesota wilderness, which is how the Voyageurs Wolf Project captured this clear, close-up footage of a stunning medium size wild cat:

That’s lynx canadensis, better known as the Canadian lynx, and the footage is so perfect it’s as if the wild cat said “Ah, a trail camera! I’m gonna sit right here and let the humans see how beautiful and regal I am!”

From its pronounced ear tufts to its snow-soft fur and dark stump of a tail, this lynx is a fantastic example of its species. Canadian lynx are well adapted to the demands of their environs in Canada and the northern US, with heavy coats and soft, wide feet that allow it to traverse snowy landscapes quickly and silently.

They’re famously elusive and difficult to track in the wild, but maybe all we have to do is give the lynx a chance to strut its stuff.
