Paperback. Condición: Good. "One of the most interesting discoveries I've seen in animal sociobiology in years." --E.O. Wilson Why do ravens, often considered solitary birds, share food with one another in the harsh months of winter? At first glance, the behavior seemed to defy the rules of evolutionary biology. Yet the more biologist Bernd Heinrich observed these intelligent corvids, the more fascinating the puzzle became. In Ravens in Winter, Heinrich presents the groundbreaking ornithological research that redefined our understanding of raven social behavior. Blending meticulous science with vivid storytelling, he explores how ravens cooperate, communicate, and thrive in ways that challenge long-held assumptions about animal behavior. "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, The New York Times.…

Hardback. Condición: Good. In essays that span several decades, Heinrich finds himself at home in his beloved camp in Maine, where he plays host to annoying visitors from Europe (the cluster flies) and more helpful guests from Asia (ladybugs); and as far away as Botswana, where he unravels the far-reaching ecological consequences of elephants? bruising treatment of mopane trees. Heinrich turns to his great love, the extraordinary behaviors of ravens, some of them close companions for years. Finally, he asks ?Where does a biologist find hope?? while delivering an answer that informs and inspires.…

Paperback. Condición: Very Good. "Each new page [is] more spellbinding than the one before--this is surely one of the most interesting books I've ever read."--Elizabeth Marshall Thomas, author of The Hidden Life of Dogs When Bernd Heinrich decided to write a memoir of his ultramarathon running experience he realized that the preparation for the race was as important, if not more so, than the race itself. Considering the physiology and motivation of running from a scientific point of view, he wondered what he could learn from other animals. In Why We Run, Heinrich considers the flight endurance of birds, the antelope's running prowess and limitations, and the ultra-endurance of camels to understand how human physiology can or cannot replicate these adaptations. With his characteristic blend of scientific inquiry and philosophical musings, Heinrich offers an original and provocative work combining the rigors of science with the passion of running.…
