The National Geographic Guide to Birding in North America

Begin by delving into the history of birdwatching in the U.S., from the early naturalists of the 18th century to today's highly organized activity. Then look into the origins of birds, and how they are linked evolutionarily to dinosaurs and early reptiles. Finally, explore bird taxonomy, and how their scientific classification aids us in identifying them in the field.

Investigate the anatomy of birds, and how understanding anatomical features aids us in identification. Then learn about the fascinating range of bird feathers, and their different functions. Observe how understanding the flight patterns of birds helps identify them in the field. Last, compare two common birds, as an exercise in using the knowledge you've learned so far.

Look first at three physical tools that you can use right away to become a more effective birder. Consider how familiarity with the shape or silhouette of bird families, as well as bird size, aid you in focusing in on exact species. Study the color factors of pigment and keratin, as they produce the dazzling range of bird coloration, and investigate color as an identification tool.

Take account of three further aids for bird identification. See how charting birds' distribution or geographical range provides much useful information about specific species. Grasp the benefits of knowing a bird's status, or abundance vs. rarity, and how status can change. Also study the factor of endemism, where birds are limited to one specific region, and the uses of this information.

Explore the North American habitats of forest, grasslands, desert, sagebrush, chaparral, and tundra, distinguishing their specific features and the amazing birds that are native to each of these environments. Add to this knowledge by investigating the roles of habitat specialization, the seasons, and migration patterns as they help us in identifying bird species.

Discuss the core optical tools that aid us in observing birds in the field. Study the parts of a pair of binoculars, and the pros and cons of different types of binoculars. Learn how to use binoculars for birding, highlighting matters such as magnification, field of view, and depth of field. Also take account of spotting scopes, and how they provide detail that binoculars can't.
