โOne of the most interesting discoveries Iโve seen in animal sociobiology in years.โ โE.O. Wilson
Why do ravens, generally understood to be solitary creatures, share food between each other during winter? On the surface, there didnโt appear to be any biological or evolutionary imperative behind the ravenโs willingness to share. The more Bernd Heinrich observed their habits, the more odd the birdโs 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 ravenโs rather unconventional social habits.
โBernd Heinrich is no ordinary biologist. Heโs the sort who combines formidable scientific rigor with a sense of irony and an unslaked, boyish enthusiasm for his subject, and who even at his current professorial age seems to do a lot of tree climbing in the line of research.โ โDavid Quammen, The New York Times
