Can animals learn another species' 'language?' | Live Science | Metaglossia: The Translation World | Scoop.it
Animals hear other species communicate around them every day. Do they understand what they're saying?

"... Communication in the animal kingdom is complex. But with all of these unique ways to communicate, is it possible for an animal to learn the "language" of another species?...


First off, it's important to note that, although "language" is a useful metaphor when we're thinking about one species understanding another, animals don't actually have languages in the way humans do...


When it comes to picking up on sounds from other species, birds are one of the best-studied animals. One study on songbird migration suggested that solitary birds could understand the calls of other bird species on their migration pathway, perhaps helping them to stay safe and navigate the long journey...


The research dispels the notion that songbird migration is a lonely journey, as was once thought. However, their data still isn't able to decode exactly what the birds are "saying."


"It's logical to wonder if there are social connections among species," Van Doren said. "I think these calls could contain more information than we currently understand."


But learning a "language" is about more than just understanding what you hear; it's about being able to speak it, too. That's where the fork-tailed drongo (Dicrurus adsimilis) — a small, black bird found across Africa — excels.


Drongos have a habit of following other animals around in the hope of stealing some of their food. Thomas Flower, a biology instructor at Capilano University in Canada, studied these birds in the field as they followed a mob of meerkats. He found that the drongos would use their own alarm calls — a squawk that indicates a predator is approaching — to scare the meerkats into their holes, allowing the drongos to swoop in and grab any food scraps.


But that strategy eventually leads to a "boy who cried wolf" situation, Flower said. The meerkats realize the drongo-specific alarm calls are a ruse, so they stop dropping their food and hiding when they hear one.


This is where the drongos' special talents come in. Fork-tailed drongos not only recognize the warning calls of the other animals around them, but they also learn to replicate those calls to their own advantage. When the birds realize their own alarm call is no longer working, they start mimicking the alarm calls of other birds — or even replicating the meerkats' own alarm call. By regularly swapping out alarm calls from different species, the drongos keep the meerkats on edge and keep the food flowing...


Flower said he still hasn't seen evidence that young drongos understand that they're deceiving other animals when they start mimicking alarm calls. But he pointed out that young humans also repeat noises they don't understand and eventually learn meaning through trial and error. For now, drongos do show some of the hallmarks of "language" learning, but much remains a mystery."
