Item #22463 Ravens in Winter. Bernd Heinrich.

Ravens in Winter

New York: Summit Books, 1989.

First Edition. Hardcover. Fine in a fine dust jacket. First printing. 379 pp, indexed and illustrated. Fine copy in fine dust jacket protected by a new mylar cover. A well written and engaging study of raven behavior in the woods of Maine. Publisher's description: "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."
