Collins Field Guide: Birds of North America

Covering most of North America, including Greenland and the highlands of Mexico, the latest Collins Field Guide focuses on the rich and diverse birdlife of what is known as the Nearctic region.
Every species found in the area is illustrated in every plumage in which they can be seen in the wild. The accompanying text concentrates on the specific characteristics and appearance of each species that allow identification in the field, including voice and distribution maps.
