Seawatching is the challenging act of identifying waterbirds in flight. Since more than one hundred different species can fly past an observation point, often at great speed or in tightly packed, mixed-species flocks, identification of these distant shapes can be a mystery.
Warblers are among the most challenging birds to identify. They exhibit an array of seasonal plumages and have distinctive yet oft-confused calls and songs. The Warbler Guide enables you to quickly identify any of the 56 species of warblers in the United States and Canada. This groundbreaking guide features more than 1,000 stunning color photos, extensive species accounts with multiple viewing angles, and an entirely new system of vocalization analysis that helps you effectively learn songs and calls.
