Chickadees and Nuthatches Join Forces

I love birds and feed many. Two of my favourites are chickadees and nuthatches so I found the following information really interesting.

Chickadees sound alarm calls—”chick-a-dee”—that vary in speed and the number of “dee” syllables depending on the threat. New research by scientists at the universities of Washington and Montana has found that nuthatches can decipher chickadee calls—the first known example of such sophisticated interspecies eavesdropping. When chickadees warn that, say, an agile owl is nearby, the nuthatches join forces with them and surround the predator, which happens to be both species’ best hope of driving it away. -> Source
