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 \u003ci\u003eRavens In Winter\u003c\/i\u003e, the first research of its kind, explores the fascinating biological puzzle of the raven's rather unconventional social habits. \u003cp\u003e\u003c\/p\u003e\"Bernd Heinrich is no ordinary biologist. He's 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.\" --David Quammen, \u003ci\u003eThe New York Times\u003c\/i\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Bernd Heinrich\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1476794561\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781476794563\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Simon \u0026amp; Schuster\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/07\/2014\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 400\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.80lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.30h x 5.40w x 1.10d","brand":"Bernd Heinrich","offers":[{"title":"Paperback","offer_id":44051582058751,"sku":"9781476794563","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_556709a4-3a57-4117-ab95-1c049965c8a9.jpg?v=1685013941","url":"https:\/\/www.whiterainbookhouse.com\/products\/ravens-in-winter-bernd-heinrich-9781476794563","provider":"WR Book House","version":"1.0","type":"link"}
