Johnsgard discusses the natural history, ecology, social behavior, and reproductive biology of each species and provides up-to-date estimates of current North American populations and trends. Separate complete accounts and range maps for the forty-four species of waterfowl known to breed in the continental United States and Canada are included, as well as identifying information on eight additional species that occasionally reach North American shorelines but are not known to breed here. The book also features an identification key, ninety head profiles, over sixty line drawings, and thirty-one color illustrations. An extended essay on the biology of waterfowl surveys variations in reproductive ecology, pair-forming behavior, flight and diving adaptations, and migratory mechanisms that are exhibited by this fascinating group of birds...."
