Oceanic birds are among the most remarkable but least known of all birds, living at sea, far from the sight of most people. They offer unusual identification challenges--many species look similar and it can be difficult to get good views of fast-flying birds from a moving boat. The first field guide to the world's oceanic birds in more than two decades, this exciting and authoritative book draws on decades of firsthand experience on the open seas. It features clear text filled with original insights and new information and more than 2,200 carefully chosen color images that bring the ocean and its remarkable winged inhabitants to life.
