Maps give the location of the area in which the bird is found. Bird-watchers have relied on the Peterson Guides over the years to identify birds, giving names, habitat, descriptions, and distribution information. However, no guide has gone that additional step to describe what the bird is doing at the time it is being observed. The book is organized so that when a particular page is consulted, it is easy to understand without referrring to other parts of the book. Each family has a brief overview that describes the bird and its feeding, nesting, and displaying characteristics.
Additional information is given for the genus, followed by detailed facts about each species.
Illustrations are clear but small, with only one per species. Of particular interest is information on certain behavior and movement characteristics, which includes how food is acquired, how young are fed, mating rituals, what the young look like and how soon they leave the nest, and how they interact with other species in the competition for food and nesting sites. Additionally, there may be information on specific species about territory claiming, social aspects, songs and calls, pairing, courtship, eggs, clutch size, incubation, number of broods per year, what they eat, how they find food, molting, roosting, and life span. Part of the Peterson Natural History Companion series, this is a must-have book to supplement any field guide. It could be used as a general field guide, although it is too big to fit into a coat pocket.
