GULLS OF THE AMERICAS STEVE N.G. HOWELL AND JON DUNN

Familiar to any beachgoer, gull species are nevertheless notoriously difficult to identify. At first glance, all gulls may appear to be the same. Howell, a birding-tour leader, and Dunn, chief consultant for and an editor of the National Geographic Field Guide to the Birds of North America, offer in this Peterson Reference Guide tips for identifying the 36 species of gulls that populate North America. The authors offer each photo as an aid to birdwatchers in appreciating the subtle variations among gull species. The guide contains vivid color plates with captions that highlight criteria for identifying each bird, text with detailed information including geographic range, plumage and other physical features, taxonomy, migration routes and timing, and maps of breeding and nonbreeding ranges. The book ends with a glossary and an extensive bibliography. Houghton Mifflin, 2007, 516 p., color plates, hardcover, $35.00.
