Besides being objects of wonder, hummingbirds, says Sheri L. Williamson in the Peterson Field Guide: Hummingbirds of North America, are unique to the New World, range in size from the smallest warm-blooded animal (Cuba's Bee Hummingbird) to outsizing songbirds (South America's Giant Hummingbird), can fly backwards and side to side, and still defy category among ornithological types. The habits, habitats, migratory patterns, physical traits, diet, mating practices, where to find them in short, all the information that a good wildlife guide offers are the stuff of Williamson's book. Clear, engaging prose and 180 full color photographs make this a natural for birdwatchers everywhere.
