I missed this when it came out — Virgina Morell, "Elephants Have an Alarm Call for Bees", Science Now 4/26/2011:

East Africa’s elephants face few threats in their savanna home, aside from humans and lions. But the behemoths are terrified of African bees, and with good reason. An angry swarm can sting elephants around their eyes and inside their trunks and pierce the skin of young calves. Now, a new study shows that the pachyderms utter a distinctive rumble in response to the sound of bees, the first time an alarm call has been identified in elephants.

… [T]he study suggests that this alarm call isn’t just a generalized vocalization but means specifically, “Bees!” says Lucy King, a postgraduate zoologist at the University of Oxford in the United Kingdom and the study’s lead author.

When they hear buzzing bees, the pachyderms turn and run away, shaking their heads while making a call that King terms the “bee rumble."

For years, the extraordinary ability of parrots to mimic sounds has raised an intriguing but largely unanswered question: what role does this ability play in the wild? This question has been difficult or impossible to study, because most parrots live in dense vegetation and move around a lot, so that no one has been able to get good records of who chirped what to whom, when and under which conditions.

Some recent work makes a start on this problem, as explained by Virginia Morrell, "Why Do Parrots Talk? Venezuelan Site Offers Clues", Science (News Focus) 7/22/2011:

Shermin de Silva, who finished her PhD in biology at Penn last year and is now the director of the Uda Walawe Elephant Research Project at Udawalawe National Park, Sri Lanka, is featured in this slide show explaining some of her research:

[Below is a guest post by Mark Seidenberg, following up on Geoff Pullum's post "Nim: the unproject", 8/16/2011.]

Nim Chimpsky and I met when I was a graduate student at Columbia. “Project Nim” is an excellent documentary, a deeply sad story leavened with humor and astonishment at the behavior of the personalities involved . The parts of the movie that cover events I observed—the period when Nim lived at the Delafield Mansion in Riverdale NY and was driven down to Columbia for teaching—was accurate as far as it went. It’s a documentary, not a detailed record of what happened, and it is stronger on Nim’s personal history and the foibles of his human caretakers (and I use the term loosely) than on the science.

I was preparing to write a commentary on the movie and the project, but then Peter Singer’s piece appeared in the New York Review of Books ("The troubled life of Nim Chimpsky", 8/18/2011). Singer is the Princeton philosopher famous for “Animal Liberation” and other influential, controversial books. His blog post about Nim got many facts wrong and I was moved to write a short response. It might be of interest to Language Log readers.

Today's SMBC:

The documentary Project Nim, about Herbert S. Terrace's effort to have a chimpanzee reared from birth like a human child and taught sign language, is an excellent piece of film-making, and you should see it. But if you go to it expecting to see something about research and data and results, there's a surprise in store for you. I now think this was not an experiment, there are no results, there is no Project Nim.

I sometimes make my way to the multiplex to see and report to you on important films that bear on language-related matters. (Sometimes unsuccessfully. You may recall my glowing account of The Oxford Murders back in 2008. I do hope the director hasn't got out of hell yet.) Back in June I tried to report to you on a special advance showing of a documentary about a chimpanzee sign-language training experiment, Project Nim, but couldn't get in. I had forgotten to allow for the fact that it was part of the Edinburgh Film Festival and (typical of the intellectual enthusiasm of this city) the place was thronged. Not a ticket to be had for love or money. (I will try to catch Project Nim soon; it is on wider release in the UK as from today.) But last night I had a significant success in that I managed to actually get in through the doors (vital prerequisite for really informed movie review) for a screening of one of the most important recent films on primatology research.

Yes, I went to see Rise of the Planet of the Apes. A rare chance to see a depiction of the actual emergence of language in a new primate species in real time. I promise that very little of the plot will be spoiled if you read on.

Christine Vendel, "Escaped chimpanzee causes a ruckus", Kansas City Star, 10/20/2010:

A 300-pound chimpanzee escaped from its owner Tuesday afternoon and ran rampant through a Kansas City neighborhood, scaring walkers, pounding on passing cars and breaking a police car’s windshield.

The 21-year-old ape, named Sueko, also pointed and laughed at residents and flipped off an animal control officer near 78th Street and Indiana Avenue, witnesses said.

If you read German or Dutch, you may be interested in the recent spate of articles about the newly-compiled Cow/German Dictionary.  I'll wait to comment until after the BBC has scrutinized the story.

No, really, I'll wait until after today's meetings are over, and I've caught up with a few chores after taking the red-eye home last night from Albuquerque via Phoenix. Anyhow, I'm guessing that the dictionary's author, Gerhard Jahns, didn't get a press release into the channels that the BBC reprints…

In fact, Dr. Jahns' research seems to be a serious and long-established project that has reached a new stage, rather than the cheese-company PR stunt behind the BBC's previous cowlingual scoop. At an earlier stage, Jahns' work got extensive coverage back in 2002.

Debate rages among philosophers, linguists, and psychologists: does Quigley know that he knows that he will die?

Nicholas Wade, "Deciphering the Chatter of Monkeys", NYT, 1/11/209, starts out with a Dr. Dolittle trope that may raise a red flag or two among those who are tired of facile anthropomorphizing in stories about animal communication:

Walking through the Tai forest of Ivory Coast, Klaus Zuberbühler could hear the calls of the Diana monkeys, but the babble held no meaning for him.

That was in 1990. Today, after nearly 20 years of studying animal communication, he can translate the forest’s sounds. This call means a Diana monkey has seen a leopard. That one means it has sighted another predator, the crowned eagle. “In our experience time and again, it’s a humbling experience to realize there is so much more information being passed in ways which hadn’t been noticed before,” said Dr. Zuberbühler, a psychologist at the University of St. Andrews in Scotland.

Do apes and monkeys have a secret language that has not yet been decrypted? And if so, will it resolve the mystery of how the human faculty for language evolved?

A Bizarro leap forward in animal abilities:
