"Paul A. Johnsgard's Hummingbirds of North America is the only book devoted to the identification, distribution, and biology - both individual and comparative - of all hummingbirds that breed in North America. First published in 1983, this acclaimed volume now has been revised and expanded to include twenty-five Mexican species, such as the long-billed starthroat and the fork-tailed emeralds, thereby more than doubling the species coverage of the original edition. Full species-by-species accounts survey the evolutionary history, anatomical and physiological specializations, and comparative ecology, behavior, and reproduction biology of this largest family of nonpasserine birds. Individual accounts are complemented by 24-full-color paintings." "Including updated range maps, identification keys, and a bibliography that has been broadened to include literature on the little-known Mexican species, the book is both accessible to amateur birders and an authoritative volume for ornithologists."--Jacket.
