National Geographic Field Guide To The Birds Of Eastern North America

Because many birds vary in color and size in different parts of their range, the National Geopgraphic bird guides offer the widest variety of images of each species to help sort out that confusion.

This essential guide features in-depth information on every bird officially recorded in eastern North America. Illustrated accounts of their plumages and life stages, and hundreds of color-coded range maps.
A full-color visual index and annotated artwork of birds' key physical features makes the content visually accessible. Thumb-tabs help readers find information fast. Durable covers stand up to outdoor use, with integrated quick-reference flaps that double as place-markers.
