“The Gorilla Foundation is sad to announce the passing of our beloved Koko,” the research center says, informing the world about the death of a gorilla who fascinated and elated millions of people with her facility for language.

Koko, who was 46, died in her sleep Tuesday morning, the Gorilla Foundation said. At birth, she was named Hanabi-ko — Japanese for “fireworks child,” because she was born at the San Francisco Zoo on the Fourth of July in 1971. She was a western lowland gorilla.

“Her impact has been profound and what she has taught us about the emotional capacity of gorillas and their cognitive abilities will continue to shape the world,” the Gorilla Foundation said.

Throughout her life, Koko’s abilities made headlines. After she began communicating with humans through American Sign Language, she was featured by National Geographic — and she took her own picture (in a mirror) for the magazine’s cover.

That cover came out in 1978, seven years after Koko was chosen as an infant to work on a language research project with the psychologist Francine “Penny” Patterson. In 1985, the magazine profiled the affectionate relationship between the gorilla and her kitten: Koko and All Ball.

In 2001, Koko made a fast friend in comedian Robin Williams, trying on his glasses, showing him around and getting him to tickle her. Then they made faces at each other — and the gorilla seemed to recall seeing Williams in a movie. Years later, in 2014, Koko was one of many who mourned Williams’ passing.


Koko amazed scientists in 2012, when she showed she could learn to play the recorder. The feat revealed mental acuity but also, crucially, that primates can learn to intricately control their breathing — something that had been assumed to be beyond their abilities.

Her ability to interact with people made Koko an international celebrity. But she also revealed the depth and strength of a gorilla’s emotional life, sharing moments of glee and sadness with researchers Patterson and Ron Cohn.

As Barbara J. King wrote for NPR about the BBC documentary Koko: The Gorilla Who Talks, when it aired on PBS in 2016:

Famously, Koko felt quite sad in 1984 when her adopted kitten Ball was hit by a car and died. How do we know? Here is nonhuman primate grief mediated through language: In historical footage in the film, Patterson is seen asking Koko, “What happened to Ball?” In reply, Koko utters these signs in sequence: cat, cry, have-sorry, Koko-love. And then, after a pause, two more signs: unattention, visit me.”


Now, it’s humanity’s turn to mourn Koko.

Thousands of people are commiserating on the Gorilla Foundation’s Facebook pageposting about Koko’s death. The top comment comes from Jess Cameron:

“Legit bawling like a baby right now. This news just breaks my heart. From an early age I was fascinated with Koko and she taught me so much about love, kindness, respect for animals, and our planet.”

With Koko’s passing, the Gorilla Foundation says it will honor her legacy, working on wildlife conservation in Africa, a great ape sanctuary in Maui, Hawaii, and a sign language app.

The foundation says those who want to share condolences can do so by emailing kokolove@koko.org.


Orca Learns to Say ‘Hello’

“Hello!” says the human. “Hello!” pipes the orca right back.

It’s not a children’s movie, but an actual orca emitting human(ish) words. An international team of researchers has taught Wikie, a 14 year-old killer whale in France, to mimic certain simple bits of speech, a discovery that gives them insight into wild orca dialects.

Repeat After Me

In all, Wikie learned six words, in addition to five orca sounds that she didn’t know before. The phrases included “hello,” “ah ha,” “one, two,” “Amy,” and “bye, bye.” She even nailed a few on her first try, though one took as many as 17 attempts to get right. The researchers taught her to “speak” by using a “copy” command that she had learned previously, though it had always been used to indicate that she should imitate physical actions, not sounds.

In a paper published Wednesday in Proceedings of the Royal Society B, the researchers detail how they first refreshed her memory on the “copy” command, and then had her repeat sounds made by her three year-old calf Moana, before progressing to unfamiliar killer whale noises. When Wikie demonstrated her imitation abilities with those sounds, the researchers moved on to human words.

When asked to say both “hello” and “one, two, three,” Wikie was able to say the phrases right back on the first try. The other words gave her a little more trouble, though she was able to repeat them with some practice. Still, Wikie was better at producing some sounds than others, though the researchers were nevertheless impressed by her ability to make human sounds given that orcas’ vocal systems look very different than ours. When asked to repeat the sounds, there was a fair amount of variability in her vocalizations, something the researchers say could be due to the simple difficulty of producing the sounds or even different levels of motivation between sessions.

Say What?

After recording her speech, the researchers had six independent judges listen to Wikie’s vocalizations to confirm that she was imitating the human sounds well enough to be understood. While the sounds may be accurate, there’s no evidence that Wikie actually understands what any of it means. Instead, it’s simply a demonstration of orcas’ ability to learn and repeat new sounds, a skill that may be at the heart of some puzzling behavior observed in the wild.


Researchers have long tracked pods of killers whales by their dialects. Each pod produces unique calls, and this research reveals that these vocalizations are passed down through learning, rather than being a genetic trait. Researchers suspected this was the case, but hadn’t gathered enough evidence of orcas learning and mimicking sounds.

Some species, though not many, can learn to repeat human sounds. Belugas and bottlenose dolphins have been observed doing it, as well as elephants. How, and why they are able to do so varies, though the researchers do note that Wikie was producing the sounds in the open air, as opposed to under water as she normally would. This could add another layer of difficulty, though it also raises questions as to whether she would learn and repeat sounds differently underwater.

Coyotes howl to chat with their neighbors

A coyote.

Coyotes are more than an icon of the American West. They are probably your neighbors.

More and more people are routinely hearing coyotes yip, bark and howl in their backyards or in other urban and suburban settings. In fact, Canis latrans, the scientific name for coyotes, means “barking dog.”

When you watch coyotes throw their heads back and sing to their heart’s content, they seem to enjoy it. That was Marc’s impression when he and his students studied wild coyotes in the Grand Teton National Park for more than eight years. It’s fun, it feels good, so why not howl?

But what are they saying?

Researchers have identified around a dozen or so coyote vocalizations. Some coyote sounds are used to defend their territory and dens and to tell other coyotes they’re around, but some vocalizations give away much more information.

There’s little evidence that vocalizations are used to coordinate pack hunting. Some research shows the alpha, or high-ranking, males and females and pairs do most of the vocalizing.

Based on extensive and detailed research that involved recording and playing back howls and yips and observing the behavior of captive and free-ranging coyotes, wildlife researcher Philip Lehner 40 years ago placed coyote sounds into three general categories:

Greeting: Sounds include low-frequency whining, wow-oo-wowing (often called a greeting song), and group yip-howling (when reuniting and greeting).

Agonistic: These are vocalizations used during aggressive interactions and when coyotes display submission. They include woofing, growling, huffing (high-intensity threat), barking, bark-howling, yelping (submission and startle), and high-frequency whining (usually given by a subordinate coyote).

Contact: Sounds include lone howling (one of the most common vocalizations), group howling (when reuniting or in response to lone or group howls or yip howls), and group yip-howling (which may announce territory occupancy and may help regulate density of population).

Howling sounds can travel around 1,000 yards and can be used by coyotes to identify who’s calling, their gender and perhaps their mood. Transient coyotes don’t usually vocalize as much as resident animals in order to avoid interactions. Lone howls can also announce the location of an individual separated from their group.

One interesting and useful discovery is that humans aren’t very good at estimating how many coyotes are around by listening to their howls. Indeed, they usually overestimate the number of individuals actually present. So the melodious cacophony and symphony of sounds shouldn’t be used to claim that numerous coyotes are all over the place.

The more we understand all aspects of coyote behavior, the easier it will be to peacefully coexist with them. We should use what we know to protect them. State and local policies should embrace our understanding of coyote behavior.

We’re fortunate to share our homes with coyotes and other animals, and it’s important that we come to appreciate and understand the fascinating animals with whom we share our magnificent planet.

Can Prairie Dogs Talk?

Con Slobodchikoff and I approached the mountain meadow slowly, obliquely, softening our footfalls and conversing in whispers. It didn’t make much difference. Once we were within 50 feet of the clearing’s edge, the alarm sounded: short, shrill notes in rapid sequence, like rounds of sonic bullets.

We had just trespassed on a prairie-dog colony. A North American analogue to Africa’s meerkat, the prairie dog is trepidation incarnate. It lives in subterranean societies of neighboring burrows, surfacing to forage during the day and rarely venturing more than a few hundred feet from the center of town. The moment it detects a hawk, coyote, human or any other threat, it cries out to alert the cohort and takes appropriate evasive action. A prairie dog’s voice has about as much acoustic appeal as a chew toy. French explorers called the rodents petits chiens because they thought they sounded like incessantly yippy versions of their pets back home.

On this searing summer morning, Slobodchikoff had taken us to a tract of well-trodden wilderness on the grounds of the Museum of Northern Arizona in Flagstaff. Distressed squeaks flew from the grass, but the vegetation itself remained still; most of the prairie dogs had retreated underground. We continued along a dirt path bisecting the meadow, startling a prairie dog that was peering out of a burrow to our immediate right. It chirped at us a few times, then stared silently.

“Hello,” Slobodchikoff said, stooping a bit. A stout bald man with a scraggly white beard and wine-dark lips, Slobodchikoff speaks with a gentler and more lilting voice than you might expect. “Hi, guy. What do you think? Are we worth calling about? Hmm?”

Slobodchikoff, an emeritus professor of biology at Northern Arizona University, has been analyzing the sounds of prairie dogs for more than 30 years. Not long after he started, he learned that prairie dogs had distinct alarm calls for different predators. Around the same time, separate researchers found that a few other species had similar vocabularies of danger. What Slobodchikoff claimed to discover in the following decades, however, was extraordinary: Beyond identifying the type of predator, prairie-dog calls also specified its size, shape, color and speed; the animals could even combine the structural elements of their calls in novel ways to describe something they had never seen before. No scientist had ever put forward such a thorough guide to the native tongue of a wild species or discovered one so intricate. Prairie-dog communication is so complex, Slobodchikoff says — so expressive and rich in information — that it constitutes nothing less than language.

Continue reading the main story

That would be an audacious claim to make about even the most overtly intelligent species — say, a chimpanzee or a dolphin — let alone some kind of dirt hamster with a brain that barely weighs more than a grape. The majority of linguists and animal-communication experts maintain that language is restricted to a single species: ourselves. Perhaps because it is so ostensibly entwined with thought, with consciousness and our sense of self, language is the last bastion encircling human exceptionalism. To concede that we share language with other species is to finally and fully admit that we are different from other animals only in degrees not in kind. In many people’s minds, language is the “cardinal distinction between man and animal, a sheerly dividing line as abrupt and immovable as a cliff,” as Tom Wolfe argues in his book “The Kingdom of Speech,” published last year.

Slobodchikoff thinks that dividing line is an illusion. To him, the idea that a human might have a two-way conversation with another species, even a humble prairie dog, is not a pretense; it’s an inevitability. And the notion that animals of all kinds routinely engage in sophisticated discourse with one another — that the world’s ecosystems reverberate with elaborate animal idioms just waiting to be translated — is not Doctor Dolittle-inspired nonsense; it is fact.

Like “life” and “consciousness,” “language” is one of those words whose frequent and casual use papers over an epistemological chasm: No one really knows what language is or how it originated. At the center of this conundrum is a much-pondered question about the relationship between language and cognition more generally. Namely, did the mind create language or did language create the mind? Throughout history, philosophers, linguists and scientists have argued eloquently for each possibility. Some have contended that thought and conscious experience necessarily predate language and that language evolved later, as a way to share thoughts. Others have declared that language is the very marrow of consciousness, that the latter requires the former as a foundation.

In lieu of a precise definition for language, many experts and textbooks fall back on the work of the American linguist Charles Hockett, who in the 1950s and ’60s proposed a set of more than a dozen “design features” that characterize language, like semanticity — distinct sounds and symbols with specific meanings — and displacement, the ability to speak of things outside your immediate environment. He acknowledged that numerous animal-communication systems had at least some of these features but maintained that only human language boasted them all. For those who think that language is a prerequisite for consciousness, the unavoidable conclusion is that animals possess neither.

To many biologists and neuroscientists, however, this notion smacks of anthropocentrism. There is now a consensus that numerous species, including birds and mammals, as well as octopuses and honeybees, have some degree of consciousness, that is, a subjective experience of the world — they feel, think, remember, plan and in some cases possess a sense of self. In parallel, although few scientists are as ready as Slobodchikoff to proclaim the existence of nonhuman language, the idea that many species have language-like abilities, that animal communication is vastly more sophisticated than Hockett and his peers realized, is gaining credence. “It’s increasingly obvious just how much information is encoded in animal calls,” says Holly Root-Gutteridge, a bioacoustician at the University of Sussex. “There’s now a preponderance of evidence.”

In the 1990s, inspired in part by Slobodchikoff’s studies, the primatologist Klaus Zuberbühler began investigating monkey vocalizations in the dense and cacophonous forests of the Ivory Coast in Africa. Over the years, he and his colleagues discovered that adult male Campbell’s monkeys change the meaning of their screeches by combining distinct calls in specific sequences, adding or omitting an “oo” suffix. Krak exclusively warns of a leopard, but krak-oo is a generalized alarm call; isolated pairs of booms are a “Come this way!” command, but booms preceding krak-oos denote falling tree branches. Studies of songbirds have also uncovered similar complexity in their communication. Japanese great tits, for example, tell one another to scan for danger using one string of chirps and a different set of notes to encourage others to move closer to the caller. When researchers played the warning followed by the invitation, the birds combined the commands, approaching the speaker only after cautiously surveying the area. In the South Pacific, biologists have shown that humpback-whale songs are neither random nor innate: rather, migrating pods of humpback whales learn one another’s songs, which evolve over time and spread through the ocean in waves of “cultural revolution.” And baby bottlenose dolphins develop “signature whistles” that serve as their names in a kind of roll call among kin.

With the help of human tutors, some captive animals have developed especially impressive linguistic prowess. Dolphins have learned to mimic computer-generated whistles and use them as labels for objects like hoops and balls. A bonobo known as Kanzi communicates with a touch-screen displaying hundreds of lexigrams, occasionally combining the symbols with hand gestures to form simple phrases. And over the course of a 30-year research project, an African gray parrot named Alex learned to identify seven colors, five shapes, quantities up to eight and more than 50 objects; he could correctly pick out the number of, for instance, green wooden blocks on a tray with more than a dozen objects; he routinely said “no,” “come here” and “wanna go X” to get what he desired; and on occasion he spontaneously combined words from his growing vocabulary into descriptive phrases, like “yummy bread” for cake.

Slobodchikoff’s studies on prairie dogs have long hovered on the periphery of this burgeoning field. Unknown to Slobodchikoff, around the same time that he began recording prairie-dog alarm calls in Flagstaff, Peter Marler, the renowned animal-communication expert and one of Slobodchikoff’s former professors, was working on a similar study, one that would eventually redefine the field. In the spring of 1977, Marler sent Robert Seyfarth and Dorothy Cheney — a young husband-and-wife duo of primate scientists — to Amboseli, Kenya, to study the alarm calls of small silver-haired monkeys known as vervets. Earlier research had hinted that vervet monkeys produced different vocal warnings for different predators: a kind of bark to warn of a leopard; a low-pitched staccato rraup for a martial eagle; and a high-pitched chutter for a python. Seyfarth and Cheney decided to further investigate these findings in a controlled field experiment.

The two scientists hid a loudspeaker in the bushes near different groups of vervets and played recordings of their alarm calls, documenting the monkeys’ responses. Even in the absence of actual predators, the recordings evoked the appropriate escape strategies. Leopard-alarm calls sent monkeys scampering into the trees. When they heard eagle-alarm calls, they looked up and took cover in the bushes. In response to the warning for snakes, the primates reared up on their hind legs and scanned the ground. Contrary to the consensus of the time, the researchers argued that the sounds animals made were not always involuntary expressions of physiological states, like pain, hunger or excitement. Instead, some animals systematically used sounds as symbols. In both academia and the popular press, vervet monkeys became celebrated mascots for the language-like abilities of animals.

While the vervet research won acclaim, Slobodchikoff’s remained frustratingly sidelined. Marler, Seyfarth and Cheney worked for the well-staffed and moneyed Rockefeller University in New York; Slobodchikoff conducted his studies on a shoestring budget, compiling funds from the university’s biology department, very occasional grants and his own bank account. Slobodchikoff did not collect enough data to formally present his research at a conference until 1986. And it was not until 2006 that he published a study with the same kind of playback techniques that Cheney and Seyfarth used in Kenya, which are essential to demonstrating that an animal comprehends and exploits the variation in its calls. Although many scientists attended Slobodchikoff’s talks at conferences and spoke with him about his research in private, they rarely referenced his studies when publishing their own. And despite a few news stories and nature documentaries, prairie dogs have not secured a seat in public consciousness as a cognitively interesting species.

It did not take long for Slobodchikoff to master the basic vocabulary of Flagstaff’s native prairie dogs. Prairie-dog alarm calls are the vocal equivalent of wartime telegrams: concise, abrupt, stripped to essentials. On a typical research day, Slobodchikoff and three or four graduate students or local volunteers visited one of six prairie-dog colonies they had selected for observation in and around Flagstaff. They usually arrived in the predawn hours, before the creatures emerged from their slumber, and climbed into one of the observation towers they had constructed on the colonies: stilted plywood platforms 10 feet high, covered by tarps or burlap sacks with small openings for microphones and cameras. By waiting, watching and recording, Slobodchikoff soon learned to discriminate between “Hawk!” “Human!” and so on — a talent that he says anyone can develop with practice. And when he mapped out his recordings as sonograms, he could see clear distinctions in wavelength and amplitude among the different calls.

He also discovered consistent variations in how prairie dogs use their alarm calls to evade predators. When a human appeared, the first prairie dog to spot the intruder gave a sequence of barks, which sent a majority of clan members scurrying underground. When a hawk swooped into view, one or a few prairies dogs each gave a single bark and any animal in the flight path raced back to the burrow. (Slobodchikoff suspects that, because of a hawk’s speed, there’s little time for a more complex call.) The presence of a coyote inspired a chorus of alarm calls throughout the colony as prairie dogs ran to the lips of their burrows and waited to see what the canine would do next. When confronted with a domestic dog, however, prairie dogs stood upright wherever they were, squeaking and watching, presumably because tame, leashed dogs were generally, though not always, harmless.

Something in Slobodchikoff’s data troubled him, however. There was too much variation in the acoustic structure of alarm calls, much more than would be expected if their only purpose was to distinguish between types of predator. Slobodchikoff arranged for various dogs — a husky, a golden retriever, a Dalmatian and a cocker spaniel — to wander through a prairie-dog colony one at a time. The recorded alarm calls were still highly variable, even though the intruders all belonged to the same predator class. “That led me to think, What if they are actually describing physical features?” Slobodchikoff remembers. What if, instead of barking out nouns, prairie dogs were forming something closer to descriptive phrases?

To find out, he became a participant in his own experiment. Slobodchikoff and three colleagues paraded through two prairie-dog colonies dressed in either jeans and white lab coats, or jeans and variously colored shirts: blue, gray, orange, green. The prairie dogs produced highly similar alarm calls for each person in the lab coat, except for one especially short researcher. But they chirped in very different ways for most of the different colored shirts. In a related experiment, three slender women differing in height by just a bit meandered through a prairie-dog habitat dressed identically except for the color of their T-shirts. Again the animals varied their calls. And in another study, prairie dogs changed the rate of their chirping to reflect the speed of an approaching human.

If prairie dogs had sounds for color and speed, Slobodchikoff wondered, what else could they articulate? This time, he and his colleagues designed a more elaborate test. First they built plywood silhouettes of a coyote and a skunk, as well as a plywood oval (to confront the prairie dogs with something foreign), and painted the three shapes black. Then they strung a nylon cord between a tree and an observation tower, attached the plywood figures to slotted wheels on the cord and pulled them across the colony like pieces of laundry. Despite their lack of familiarity with these props, the prairie dogs did not respond to the cutouts with a single generalized “unknown threat” call. Rather, their warnings differed depending on the attributes of the object. They unanimously produced one alarm call for the coyote silhouette; a distinct warning for the skunk; and a third, entirely novel call for the oval. And in a follow-up study, prairie dogs consistently barked in distinct ways at small and large cardboard squares strung above the colony. Instead of relying on a fixed repertory of alarm calls, they were modifying their exclamations in the moment to create something new — a hallmark of language Hockett called “productivity.”

How Fish Communicate


Credit Victoria Roberts

It is well known that fish communicate by gesture and motion, as in the highly regimented synchronized swimming of schools of fish.

Some species use electrical pulses as signals, and some use bioluminescence, like that of the firefly.

Some kinds of fish also release chemicals that can be sensed by smell or taste. In 2011, a scientist in New Zealand suggested that what might be called fish vocalization has a role, at least in some ocean fish.

In the widely publicized work, done for his doctoral thesis at the University of Auckland, Shahriman Ghazali recorded reef fish in the wild and in captivity, and found two dominant vocalizations, the croak and the purr, in choruses that lasted up to three hours, as well as a previously undescribed popping sound.

The sounds of one species recorded in captivity — the bigeye, or Pempheris adspersa — carried 100 feet or more, and the researcher suggested it could be used to keep a group of fish together during nocturnal foraging. Another species, the bluefin gurnard, or Chelidonichthys kumu, was also very noisy, he found.

“Vocalization” is a bit of a misnomer, as the sounds these fish make are produced by contracting and vibrating the swim bladder, not by using the mouth. question@nytimes.com

Wolves and Dogs Speak With Their Eyes


Wolves and dogs can communicate using their eyes alone, suggests a new study in the journal PLoS ONE.

The color of the face around the eye, the eye’s shape and the color and shape of both the iris and the pupil are all part of the elaborate eye-based communication system, according to the research, which could apply to humans as well.

Sayoko Ueda of the Tokyo Institute of Technology and Kyoto University led the study, which compared these characteristics of the face and eyes among 25 different types of canines.

Dolphin Speak: Did a Dolphin Really Say “Seaweed”?



”I don’t see a fundamental white line that distinguishes us from other animals.” Dr. Terrence Deacon
Dolphin tool use influences a population’s genetic structure and they may talk.
Dolphins are unquestionably highly charismatic animals. They have unique and sophisticated communication skills and also are known to use tools, including sponges to protect their sensitive beaks, when foraging for food.

During the past two weeks I came across two extremely interesting articles about these crafty cetaceans. The first, titled “Dolphin whistle instantly translated by computer” by Hal Hodson, considers the possibility that dolphins are able to whistle the same words we use to denote an object. The print version of the latter essay is called “Decoding dolphin.” The second, called “Cultural transmission of tool use combined with habitat specializations leads to fine-scale genetic structure in bottlenose dolphins” by Anna Kopps of the University of New South Wales and her colleagues, focuses on their use of protective sponges during foraging and its effect on the genetic structure of dolphin populations.

Say what? Did you really whistle seaweed?

Denise Herzing is well known for her and her team’s long-term field research on Atlantic spotted dolphins. Among many aspects of the amazing lives of dolphins, she has long been interested in dolphin communication and whether or not they and other animals use language to communicate with one another or can use language to communicate with us.

While it’s too early to know for sure, there is compelling evidence that some animals are language users (see, for example, a brief review of the research by Dr. Con Slobochikoff on prairie dogs). I found Hal Hodson’s essay called “Decoding dolphin” to be an extremely interesting, stimulating, and easy read. To wit, and I encourage you to take a few minutes to read it, Mr. Hodson begins: “IT was late August 2013 and Denise Herzing was swimming in the Caribbean. The dolphin pod she had been tracking for the past 25 years was playing around her boat. Suddenly, she heard one of them say, ‘Sargassum'”. And, what did Dr. Herzing exclaim? “‘I was like whoa! We have a match. I was stunned.'” Dr. Herzing “was wearing a prototype dolphin translator called Cetacean Hearing and Telemetry (CHAT) and it had just translated a live dolphin whistle for the first time.” So, “When the computer picked up the sargassum whistle, Herzing heard her own recorded voice saying the word into her ear.” I, too, would have been stunned and I can’t wait for more research in this fascinating area of study.

Perhaps we are not the only animals who use language. Dr. Terrence Deacon, a neuroscientist at the University of California, Berkeley, who also is an expert in animal communication, notes, “I don’t see a fundamental white line that distinguishes us from other animals.” Only time and research will tell if we’re alone in the language arena. For now it’s a good idea to keep the door wide open.

Cultural hitchhiking: Was there a “sponging Eve”?

An informative summary of the research on the genetics of tool use in dolphins living in Shark Bay in Western Australia can be found in an article called “Cultural hitchhiking: How social behavior can affect genetic makeup in dolphins.” It turns out that the culturally transmitted use of sponges—called vertical social transmission—can actually “shape the genetic makeup” of wild dolphins. Dolphins, who live deep in the bay, show mitochondrial DNA (mtDNA) types called Haplotype E or Haplotype F that are inherited solely from the mother, whereas non-sponging dolphins who live in shallower water mainly show Haplotype H. All of the 22 sponging dolphins who were observed turned out to be members of one matriline and were Haplotype E.

This novel and significant discovery demonstrates a strong correlation between haplotype and habitat. According to Dr. Kopps, “Our research shows that social learning should be considered as a possible factor that shapes the genetic structure of a wild animal population.” She also notes, “For humans we have known for a long time that culture is an important factor in shaping our genetics. Now we have shown for the first time that a socially transmitted behaviour like tool use can also lead to different genetic characteristics within a single animal population, depending on which habitat they live in.” This is one of the first demonstrations of what is called “cultural hitchhiking” in nonhuman animals.

What an exciting time it is to study the behavior of nonhuman animals. Stay tuned for more on their fascinating lives.

Computer Identifies Individual Wolves’ Howls

By Marc Lallanilla, Assistant Editor   |   July 23, 2013

The howl of a wolf in the wilderness may make your spine tingle — it has a similar effect on wolf conservationists, who have struggled for years to accurately analyze the sounds that wolves make. Researchers at Nottingham Trent University (NTU) in England have now developed a computer program that can identify the signature howl of an individual wolf with pinpoint accuracy. Just like a person’s voice, the howl of a wolf has a specific pitch and volume. But identifying each wolf’s howl has been difficult, especially in the wild, where wind and water can muffle and distort the sound. It gets even more challenging when a pack of wolves starts howling in unison. – See more at:
[Gee, maybe animals aren’t so dumb after all…On a related note]:

Scientists have found further evidence that dolphins call each other by “name”.

Research has revealed that the marine mammals use a unique whistle to identify each other.

A team from the University of St Andrews in Scotland found that when the animals hear their own call played back to them, they respond.

The study is published in the Proceedings of the National Academy of Sciences.

Dr Vincent Janik, from the university’s Sea Mammal Research Unit, said: “(Dolphins) live in this three-dimensional environment, offshore without any kind of landmarks and they need to stay together as a group.

“These animals live in an environment where they need a very efficient system to stay in touch.”

Signature whistles

It had been-long suspected that dolphins use distinctive whistles in much the same way that humans use names.

Previous research found that these calls were used frequently, and dolphins in the same groups were able to learn and copy the unusual sounds.

But this is the first time that the animals response to being addressed by their “name” has been studied.

Scientists Should Wake Up and Smell the Fish Farts

When studying something which can be tested in a lab, scientists don’t hesitate to employ the tried and true formula: if it looks like shit, and smells like it, chances are it’s actually shit. When it comes to literal excrement, some scientists are real whizzes. Even without a DNA test, they can tell you with near-certainty through which species of animal’s anus a particular scat has passed. But when it comes to animal sentience, some scientists still don’t know shit (pardon my French—throughout).

Thanks to his creator, author Arthur Conan Doyle, the criminologist Sherlock Holmes famously pointed out that, “If you’ve eliminated all other possibilities, whatever remains must be the truth.” Well, scientists have spent centuries toying with every other possibility to avoid the obvious fact that non-human animals are conscious, thinking, feeling beings.

Incredibly, there are some who’re still grappling with the question: “Are animals aware?” What the fuck—of course they’re aware! Most animals are far more aware of their surroundings than the average human, for that matter.

The science of animal behavior has come a long ways from the dark days of Rene Descartes, thanks to the likes of Donald Griffin, Marc Bekoff and other pioneers in the study of cognitive ethology. Just last summer, an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” The document stated that “humans are not unique in possessing the neurological substrates that generate consciousness,” and concludes that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”

Having witnessed remarkably intelligent actions on the part of individuals throughout the animal kingdom—from the family dog leaping to his feet at the whispered mention of a “walk” or “car ride,” to a herd of wild bison mourning over the remains of their dead—my response to the Cambridge Declaration on Consciousness in Non-Human Animals is, “Well duh, tell us something we don’t know.”

Speciously, the Cambridge Declaration drew an arbitrary line and left the world of fishes out in the cold when it comes to animal consciousness. Far too many of today’s “behaviorists” still ascribe to the long outdated notion of fish the way science had long thought of all non-human animals—as automatons: mindless machines going through life without any more than random responses to stimuli.

Now I’m in no way anti-science—far from it, in fact—I just think that sometimes a scientist will spend an exorbitant amount of time chasing his or her tail when the answer they’re looking for is as plain as the nose on their face.

Take the question of animal communication, for example. We all know whales and dolphins are able (when they can find a quiet stretch of ocean—devoid of the deafening drone of ships or navy sonar) to communicate with one another through songs or clicks, respectively. But lately observers have learned that even fish have devised clever ways to keep in touch. According to an article entitled “Fish Farts: Herring Use Flatulence To Communicate” in the Huffington Post, apparently some types of herring pass gas to “speak” to each other without alerting other fish.

Researchers Bob Batty, Ben Wilson and Larry Dill made that Nobel Prize-worthy discovery after studying Pacific and Atlantic herring in Canada and Scotland, noting (importantly) that the gas is not caused by the digestive process. Instead, the fish swallow air from the surface and emit it through a small opening near their bung holes. Thus, profound as they may be, the bubbles aren’t really farts in the stinky, human sense.

So, it seems to me a bit arrogant to write an entire class of animal life out of a “Declaration on Consciousness in Non-Human Animals.” Granted, herring may not be flatulent enough to recite the Preamble to the Constitution, but then, as Georg Christoph Lichtenberg wrote, “Only a man can draw a self-portrait, but only a man wants to.”

Time for skeptical scientists to wake up and smell the sentience when it comes to fish.
