This is And same goes for the bird world. Each bird species has effectively its own language.

Andy Radford, a professor of behavioral ecology at the University of Bristol.

And there might be similarities between some languages, just as there are in the human world,

and then there are other languages that sound extremely different even though they're conveying exactly the same meaning.

In fact, some birds are known to pick up on the language of other species.

In particular, they've learned to detect danger by eavesdropping on the alarm calls of other birds.

Radford and his colleagues wanted to investigate how that learning occurs,

so they first played an alarm call

that Fairy Wrens, an Australian bird, shouldn't be familiar with with a computer-generated alarm call meant to mimic a

birds. As expected the unfamiliar sound had no effect on the fairy rents but then the

researchers paired the synthetic call,

where the chorus of alarm calls the rents would recognize.

And after the training, the sound of the initially unfamiliar synthetic call alone was enough

to send the birds ducking for cover.

The results are in the journal Current Biology.

Radford says the study shows birds can learn from their peers

without ever seeing them, or a predator either.

And so I think that's the coolest thing of all,

is that you can learn with your eyes shut about something really important in the natural world.
