Elephants Call Each Other By Name, Study Says

Elephants encode names and other information in low-frequency rumbles that can be heard miles away. For social animals who live in large herds, it’s crucial to be able to address individuals.

Elephants are famously social animals, moving in matriarchal herds that can consist of as many as 70 of their kind.

They also communicate over long distances, emitting rumbles that can be heard miles away.

Because of their social and nomadic existence, it makes sense that elephants would need a way to single out individuals and address each other, and for the first time researchers say they’ve found evidence of Earth’s largest land animals calling each other by name.

“If you’re looking after a large family, you’ve got to be able to say, ‘Hey, Virginia, get over here!’” Duke University ecologist Stuart Pimm told the Associated Press.

The research involved field work and analysis using artificial intelligence. To record samples of elephants communicating, teams followed herds with recording equipment. Notably, elephant rumbles include sounds in frequencies lower than the human ear can detect.

The team paid close attention when one elephant vocalized and another responded, and recorded who initiated each rumble and who it was meant for.

Although elephants are best known for making loud “trumpeting” sounds, experts say those are more like exclamations while rumbles contain encoded information that African savanna elephants would need to communicate to each other.

“The rumbles themselves are highly structurally variable,” said Mickey Pardo, a biologist from Cornell University and co-author of the study. “There’s quite a lot of variation in their acoustic structure.”

A machine learning algorithm was then used to sort and categorize the large number of audio samples, looking for patterns that are difficult for human minds to detect.

“Elephants are incredibly social, always talking and touching each other — this naming is probably one of the things that underpins their ability to communicate to individuals,” said George Wittemyer, an ecologist at Colorado State University and co-author of the study. “We just cracked open the door a bit to the elephant mind.”

Notably, the elephant “names” are identifiers that they created for themselves, and are not the kind of human-bestowed names that cats and dogs respond to. The list of animals who have names for themselves is short, although likely to expand with further study. Dolphins, for instance, identify themselves with unique whistling patterns, and parrots have a similar method, but both species address individuals by imitating their calls. Elephants use their name analogs the way humans do, to directly address each other.

The research has the potential to raise public awareness of elephant intelligence and their plight as they face threats to their continued existence. Like almost all of the Earth’s iconic megafauna, elephants will become extinct if we don’t do a better job protecting them and ending the ivory trade. Every year about 20,000 elephants are slaughtered for their tusks to feed the demand for ivory, especially in China where it’s considered a status symbol, according to the World Wildlife Fund.

Yang Feng Glan, known as the”Queen of Ivory,” was sentenced to 15 years in prison by a Tanzanian court in 2019. Yang smuggled some 860 elephant tusks worth $6.5 million from Tanzania to China as the leader of one of the world’s most extensive poaching and ivory smuggling organizations.

During her years operating the smuggling ring, Yang presented herself as a successful businesswoman and ran in elite circles within China, authorities said. Two of her accomplices were also given 15-year sentences for their roles, but since then others have filled the vacuum left by Fang’s conviction, and elephant preserves are constantly under threat from heavily armed poachers.

Foundation Offers $10m For ‘Cracking The Code’ Of Animal Language

Think you can decipher the rhythmic clicks and whistles of dolphins or the grunts and alarm calls of monkeys? A foundation is offering big prizes for progress in communicating with animals.

Looking to prompt renewed efforts at decoding animal communication, a non-profit founded by an investor and a university are offering prizes — including a hefty $10 million — to teams that can figure out what animals are “saying.”

The Coller Dolittle Challenge for Interspecies Two-Way Communication is a collaboration between the Jeremy Coller Foundation and Tel Aviv University. (Yes, it’s named after that Dr. Dolittle.)

Entrants aren’t asked to come up with a Star Trek-like “universal translator” for animals. Rather, the people behind the Coller Dolittle Challenge want to see methods that allow for two-way communication between humans and individual species.

“We are open to any organism and any modality from acoustic communication in whales to chemical communication in worms,” said Yossi Yovel, a professor at Tel Aviv University and co-chairman of the challenge.

The grand prize is a $10 million grant or $500,000 in cash, chosen by the winner, while the Foundation will offer $100,000 prizes each year for the best entries that make significant progress toward communicating with animals. The yearly prizes will be assessed “for significant contributions to decipher, interface or mimic non-human organism communication.”

While it may seem far-fetched — and there are those who believe humans will never be able to fully understand animal communication in proper context — there have been efforts to communicate with and decode the communications of bats, dolphins, whales and some primate species. Scientists have also pushed the boundaries on understanding group communication, such as the coordination involved in avian murmurations.

The organizers believe artificial intelligence will be the tool that ultimately helps crack the communication barrier, but entrants aren’t required to use AI. The technology is incredibly useful for tasks involving pattern recognition and sorting large amounts of data, both of which are important in this kind of work when researchers are tasked with analyzing thousands of audio samples or hundreds of hours of footage.

Alas, we don’t think the foundation will be interested in the Buddinese language, which boasts 327 different ways of demanding food and features a timekeeping and calendar system based on meals and naps. A short trill followed by a series of staccato meows, for example, means “I expect prompt service at salmon o’clock,” while a truncated meow ending with a scoff is used to indicate displeasure when a human napping substrate tosses too much during sleep.

Still, maybe we’ll dress it up to make it look properly academic and give the challenge a try. Those prizes could buy a lot of Roombas!

Tribe Discovers Ancient Three-Toed Cat’s Fossilized Footprint Deep In Forest

The strange footprint may date back as far as 35 million years ago, according to a preliminary analysis.

Before house cats, tigers and lions, before sabretooth cats and their scimitar-toothed relatives, Pseudaelurus (pseudo-cat) stalked the forests and plains of Europe, Asia and North America between eight and 20 million years ago.

Before Pseudaelurus, Proailurus — an animal whose name literally means “before cats” — stalked the Earth beginning 30 million years in the past.

Proailurus was thought to be the earliest true feliform ancestor, but now there may be evidence of a felid or feliform animal that predates both Proailurus and Pseudaelurus. Feliform is a term that encompasses cat-like creatures both extinct and extant, from familiar felines to civets and mongoose.

Deep in South India’s Nallamala Forest, near one of the country’s largest tiger reserves, members of the aboriginal Chenchu tribe found a fossil that could put the cat lineage back even further.

The fossil is well-preserved and clearly defined, made by an animal whose paw was about the size of an adult man’s hand. It bears a striking resemblance to tiger pug marks, but perhaps the most striking feature is its three toes.

“Based on the distinctive characteristics of the sandstone, identified as the Cuddapah subgroup Quartzitic sandstone, the estimated rock’s age is approximately 35 million years,” archaeologist Arun Vasireddy told the Times of India. “It was around this time that sandstones were formed and it is likely that the animal would have cast its prints.”

Biologists have had to reshuffle their picture of felid lineage many times over the past century and a half as new discoveries uncover previously unknown species of cats and cat-like creatures. Since they first appeared, cats have taken hundreds of different forms with significant variations in size, appearance, hunting methods and preferred terrain.

The experts aren’t popping the champagne yet. There’s a lot more work to do before they can declare a newly-discovered species or even offer more than educated guesses about its niche and appearance.

Nallamala Forest may yet hold more secrets, and research teams will look for additional prints as well as potential remains. It’s a process that will unfold over years and decades, perhaps even longer.

Still, it’s a tantalizing clue about the past and the origin of some of Earth’s most iconic animals.

In the meantime, Vasireddy said, “nothing can be said clearly until further research.”

House Cat Mistaken For A Puma, Plus: The Late Novelist Caleb Carr On His Love For Cats

Caleb Carr credits cats for showing him love during his difficult childhood when he was frequently beaten by his father.

A “mountain lion” spotted near a trail in Ventura County, California, was actually just a house cat, authorities said this week.

California’s Department of Fisheries and Wildlife dispatched staff to the area in question, the Los Padres trail in Thousand Oaks, after neighbors there reported what they thought was a baby mountain lion. One family had footage of the interloper captured on a doorbell camera.

The alleged puma turned out to be a house cat, which is a surprisingly common outcome when authorities look into alleged mountain lion sightings. Despite their size, pumas are genetically closer to felines — small and medium-size cats that can purr and meow — than they are to panthera, the genus that includes tigers, lions, jaguars and leopards.

Their gait is almost identical to that of familiar felis catus, their golden coats can look dark at night, and cats can look like pumas — or the other way around — when there’s not enough visual context to gauge the animal’s size, especially in footage captured on cell phones and security cameras, which are almost always equipped with digital zoom instead of the true optical variety.

We know what you’re thinking: this house cat must have been an impressive specimen if it was mistaken for a puma, so there’s a good chance it was Buddy. However, we can confirm that Buddy the Cat definitely was not wandering around California this week.

Novelist found solace in the company of cats

Author Caleb Carr passed away on May 23, and the Los Angeles Times has a nice tribute to him by a reporter who bonded with Carr over their shared love of cats. The writer, 68, had been suffering from cancer for some time.

Carr was known for his crime thrillers (The Alienist, The Angel of Darkness) and military history books, and he spent part of his career teaching military history at Bard College in New York. (Just a short ride from our own alma mater, Marist College.)

Carr’s last book is a tribute to his cat and her species.

Despite his publisher requesting another crime thriller, Carr decided his last book would be about a cat. Specifically his rescue cat Masha, who helped him through difficult times, and the cats of his childhood who comforted him when he was beaten by his father, Beat Generation figure and author Lucien Carr.

“It’s amazing to think about it now, but there were cats, and other animals, that were trying to make me feel better,” Caleb Carr told the Times. “The idea of that was so at odds with everything I was experiencing.”

Carr credits those felines for helping him avoid the abyss, telling the interviewer he “could have been one of those dead-eyed drone troublemakers that comes out of an abusive household very easily, if it hadn’t been for cats.”

Some people were disappointed that Carr didn’t have another novel like The Alienist in him, but Little, Brown publisher Bruce Nichols liked the idea, and the finished book was titled My Beloved Monster: Masha, The Half-Wild Rescue Cat Who Rescued Me.

Puma P-22’s Potential Successor Tries Out Hollywood Range

The new puma will have big paw prints to fill if it decides to make its famous predecessor’s range its own. People in Los Angeles are thrilled to have another mountain lion prowling the Hollywood Hills.

When the mountain lion known as P-22 died in late 2022, people in Los Angeles were so distraught they painted murals of him on building facades, buried him after a indigenous tribal funeral and even held a festival in his honor.

The famous feline had already been the subject of books, documentaries and an iconic photograph by National Geographic’s Steve Winter. The image showed P-22 in mid-stride, perfectly centered in a small pool of light beneath the Hollywood sign in the hills of Los Angeles at night. It was a natural symbol of wildlife adapting and surviving.

The love for P-22 wasn’t only based on the incredible fact that a mountain lion had established his “range” in Griffith Park, an oasis of wilderness surrounded by urban landscapes. The puma had to cross Interstate 405 and Route 101, heavy-traffic highways that are famously lethal to his species, to get there. For the next decade he skillfully avoided cars and trucks as he went about his business, popping up on trail cameras or in the backyards of Los Angelinos.

Now there’s a potential successor to the vacant throne.

The new puma isn’t collared and wildlife experts don’t know where it came from, but like P-22 it had to cross several dangerous highways to reach the city.

It’s not clear yet if the mountain lion is male or female. Jeff Sikitch, a biologist with the National Parks Service who is part of an ongoing, decades-long study of pumas, told the Los Angeles Times that he thinks the cat is likely a young male, but there’s not much to go on so far except for witness sightings and a low-resolution video taken by a man who lives in an apartment building near the edge of Griffith Park.

“Will this cat be as skilled as P-22 was at avoiding cars for a decade?” the National Wildlife Federation’s Beth Pratt told the BBC. “We don’t know what’s going to happen here.”

For now, wildlife officials are waiting and watching to see if the potential puma successor puts down roots in P-22’s old hunting grounds or tries to make the dangerous trek out of the city.

If the new puma decides to stay, it will enjoy plentiful deer and a benefit most members of its species do not have — a local population that understands mountain lion attacks are extraordinarily rare, and will support them by giving them a wide berth.

On the other hand, despite the 4,000 acres of Griffith Park and the residential neighborhoods below, the cat’s inherited range would be much smaller than what’s typical for the species. Like humans cramming belongings into apartments, pumas sacrifice space when they live in or around cities.

Suzanne Pye, a local who admired P-22 from afar, said she welcomes the newcomer and isn’t worried about attacks on people. The presence of a mountain lion after almost 18 months without one prowling the hills, she said, will add “a frisson of excitement to the morning hikes.”
