The Sibley Guide to Bird Life and Behavior

From the creator of the seminal field guide, The Sibley Guide to Birds, comes another indispensable book for bird watchers. This veritable bible to the world of birds is the collaborative effort of 48 expert birders and biologists, who combine scientific accuracy and detail with an easily readable and well-organized format. How does a tiny chickadee survive subzero temperatures? How do flocks of birds synchronize their flights? How can an albatross cross miles of ocean without flapping its wings? Which bird brains are actually intelligent? It's all here in essays giving an overview of avian evolution, biology, and the aerodynamics of flight and in chapters devoted to the 80 bird families of North America, each one detailing taxonomy, habitats, feeding, breeding, vocalizations, migrations, and more. Concerned about declining populations, Sibley also discusses the conservation status of each species and the factors that threaten them. This fascinating source of information is destined to be a well-thumbed companion. -- Lesley Reed
