Requirements: .ePUB, .MOBI/.AZW reader, 21.8 MB
Overview: Why should ravens–which are usually solitary birds–share valuable food in the dead of winter? How clever are these birds?

Why do ravens, generally understood to be solitary creatures, share food between each other during winter? On the surface, there didn’t appear to be any biological or evolutionary imperative behind the raven’s willingness to share. The more Bernd Heinrich observed their habits, the more odd the bird’s behavior became. What started as mere curiosity turned into an impassioned research project, and Ravens In Winter, the first research of its kind, explores the fascinating biological puzzle of the raven’s rather unconventional social habits.

Do they have a language?

These are some of the riddles that noted sociobiologist Bernd Heinrich, author of Bumblebee Economics and winner of the John Burroughs Medal, explores in this intriguing book. 16 pages of drawings.
