A Reference Guide to Gulls of the AmericasBook - 2007
"This guide brings together identification criteria for the 36 species of gulls that occur in the Americas - 22 that breed in North America, 10 that breed in South America, and another 4 that have occurred as visitors from the Old World. The 1,160 photographs were selected to show a representative range of plumages, with an emphasis on birds of typical appearance. Species accounts include comprehensive information on field identification, status and distribution, habitat and behavior, molt, and hybrids." "The only guide that so thoroughly covers the gulls of North and South America, this authoritative reference is an essential addition to every birder's library."--BOOK JACKET.
