How birds migrate
On the Wing: American Birds in Migration
by Carol Lerner
This is an in-depth look at the migration patterns of North American birds. Specific birds are used as examples to explain partial migration, migration within continents, east-west migration, and other seasonal movements. Accompanying maps show summer, winter, and year-round ranges. Other pictures and diagrams clarify flight patterns, diet changes, and ornithological experiments, which explain how birds find their way.
Well-researched and clearly written, this is an excellent book for beginner birdwatchers.
