Today's Liberty Meadows:

Headline from the Bangor Daily News (Feb. 13, 2019): "Maine now holds the world record for most people calling a moose at the same time."

Screenshot for posterity:

Update: The headline has been changed to read, "Maine now holds the world record for simultaneous moose-calling."

When human beings hear others speaking but are unable to comprehend what is being said, to what do they compare such speech?  We will gain one common characterization from this article about a prematurely dying Iraqi dialect:

"Iraqis amid Mosul's silent ruins fear the loss of a dialect", by Sam Kimball, SFGate (2/1/19)

It begins thus:

For centuries, residents of Mosul have spoken a unique form of Arabic enriched by the Iraqi city's long history as a crossroads of civilization, a singsong dialect that many now fear will die out after years of war and displacement.

Much of Mosul's Old City, where speakers of the dialect are concentrated, was completely destroyed in the war against the Islamic State group. Thousands of residents were killed in months of heavy fighting, and tens of thousands fled, taking with them the city's local patois and memories of its more cosmopolitan past.

"Koko, the Gorilla Who Knew Sign Language, Dies at 46", Associated Press 6/21/2018:

Koko the gorilla who mastered sign language, raised kittens and once playfully tried on the glasses of the late actor Robin Williams, has died. She was 46.

The Gorilla Foundation says the western lowland gorilla died in her sleep at the foundation's preserve in California's Santa Cruz mountains on Tuesday.

Koko's capacity for language and empathy opened the minds and hearts of millions of people, the foundation said. She appeared in many documentaries and twice in National Geographic. The gorilla's 1978 cover featured a photo that the animal had taken of herself in a mirror.

Yesterday's edition of the comedy radio news quiz "Wait, wait, don't tell me" featured some discussion of the Talking Orcas story that Geoff Pullum discussed a few days ago in "Orca emits speech-like sound; reporters go insane", 1/31/2018. The whole discussion is worth a listen:

Sometimes a new experimental result suggests a very different way of interpreting older results. On a visit a couple of days ago to Ofer Tchernichovski's lab at Hunter College, I encountered a striking example of this effect.

The background is the experimental literature on zebra finch song learning. If one of these birds is raised in acoustic and social isolation, it never learns to sing a species-typical song, but rather continues to produce "proto-song", which is a sort of songbird equivalent of grunts and groans. In contrast, with a relatively brief exposure to an example of adult song during a "critical period" early in life, a bird will (later on) learn to sing properly, in fact imitating the tutor's song quite closely. Crucially, species-typical zebra finch song is made up of discrete "syllables" arranged in regular "motifs", whereas proto-song is relatively diffuse and non-categorical at all time scales.

A decade ago, I reported on some fascinating work from Ofer's lab showing that species-typical song can emerge over a few generations in a colony raised in acoustic isolation, never encountering any external adult models ("Creole birdsong?" 5/9/2008).

Now a newer experiment (Olga Fehér et al., "Statistical learning in songbirds: from self-tutoring to song culture", Phil. Trans. R. Soc. B 2016) adds a result that makes us think differently about the earlier work.

"Who'll win at Wimbledon? Just listen to the pitch of the grunts", University of Sussex press release 7/4/2017:

Never mind counting aces and killer shots. If you want to predict the outcome of a tennis match, pay attention to the players’ grunts.

As Wimbledon prepares for another year of the on-court cacophony from the likes of Rafael Nadal and Victoria Azarenka, a new study has revealed that grunts produced by players during tennis matches they lost were higher in voice pitch than during the matches they won.

What’s more, psychologists at the University of Sussex found that players displayed differences in their grunt pitch long before the scoreboard made it clear whether they would win or lose.

From an anonymous correspondent:

I had wanted to ask you about niǎoyǔ 鸟语 ("bird language") after listening to an interview with Garry Kasparov. During the interview, he and the interviewer, the economist Tyler Cowen, get into a fairly abtruse discussion of chess. I'll paste the most relevant part of the transcript:

Ferris Jabr recently published in the New York Times Magazine an interesting article about the field research of Con Slobodchikoff, professor emeritus of biology at Northern Arizona University, on prairie dog alarm calls. The article title is "Can Prairie Dogs Talk?"

It is an interesting question. People who have read my earlier posts on animal communication have been pressing me to say something about my reaction to it. In this post I will do that. I will not be able to cover all the implications and ramifications of the question, of course; for one interesting discussion that has already appeared in the blogosphere, see this piece by Edmund Blair Bolles. But I will try to be careful and scholarly, and in an unusual departure (disappointingly, perhaps, to those who relished my bitterly sarcastic remarks on cow naming behavior), I will attempt to be courteous. Nonetheless, I will provide a clear and explicit answer to Jabr's question.

At last, an animal communication story involving healthy skepticism rather than vacant-eyed credulity, and human sagacity rather than wondrous communicative brilliance by our furry, finned, or feathered friends. Read on to be reassured about the intelligence of your species.

Rachel Premack, "Watch: This orangutan is uprooting what we previously knew about language", Washington Post 7/28/2016:

At first glance, this video of an orangutan imitating a trainer’s grunts may not seem incredibly significant. But primate researchers say Rocky, the 11-year-old orangutan in the video, could fundamentally alter how we think about spoken language.

“We don’t know exactly how human language emerged, but we do know that great apes have the cognitive ability to understand language,” said Robert Shumaker, executive vice president and zoo director at the Indianapolis Zoo. “We can no longer say that humans are the only species who can learn new vocalization and control [it] using the vocal folds or voice box.”
