The Gull Guide: North America

It is packed with the very latest research on field identification, updated taxonomy, current distribution trends, color maps, and helpful notes on natural history, aging, and molt. The Gull Guide integrates the essential elements that are critical to understanding gulls, setting an entirely new standard for identifying and enjoying these marvelous birds.
