An all-new holistic approach to identifying shorebirds.

Join the experts in birding by impression, a revolutionary approach to bird identification. Experienced birders use the most easily observed characteristics size, structure, behavior, and general color patterns to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the...

In this companion volume to Bird Coloration: Volume 1, Mechanisms and Measurements, Geoffrey E. Hill and Kevin J. McGraw have assembled some of the world's leading experts in the function and evolution of bird coloration to contribute to a long-overdue synthesis of a burgeoning field of inquiry. In Volume 2, the authors turn from the problem of how birds see and produce color and how researchers measure it, to what is the function of the colorful displays of birds and what are the factors that shape the evolution of color signals.

The contributors to this volume begin by...

This engaging chronicle of how the author and the great horned owl "Bubo" came to know one another over three summers spent in the Maine woods--and of how Bubo eventually grew into an independent hunter--is now available in an edition that has been abridged and revised so as to be more accessible to the general reader.

This is the first field guide to the identification of the birds of the islands of the tropical Pacific, including the Hawaiian Islands, Fiji, Samoa, Tonga, southeastern Polynesia, and Micronesia. It is intended both as a reference for the expert and as an introduction to birding in the region for the novice. Small enough to be carried afield, it contains much previously unpublished information about behavior, vocalizations, ecology, and distribution. The forty-five color plates depict all plumages of all bird species that breed in the islands, as well as of those that regularly visit them...

This is the first paperback version of the second edition of the popular A Guide to the Birds of Panama. In the second edition, published in 1989, the authors expanded information on the birds of Costa Rica, Nicaragua, and Honduras: approximately 200 new species were added to the material in the 1976 edition. Over 300 additional species, some of them Panamanian, were illustrated. Sixteen new plates were added, and three of the original plates were replaced by improved versions. Throughout the book changes were made to accommodate the explosion in knowledge of the birds of Panama and nearby...

Florida Scrub Jays are an excellent example of a cooperative-breeding species, in which adult birds often help raise offspring not their own. For more than a decade Glen E. Woolfenden and John W. Fitzpatrick studied a marked population of these birds in an attempt to establish a demographic base for understanding the phenomenon of "helping at the nest." By studying both population biology and behavior, the authors found that habitat restraints, rather than kin selection, are the main source of the behavior of Florida Scrub Jays: the goal of increasing the number of close relatives other...

Ever since the acorn woodpecker was observed and described by Spanish explorers, its behavior--particularly the unique habit of caching acorns in specialized storage trees or granaries--has impressed observers. Acorn woodpeckers are also one of the few temperate zone species in which young are reared communally in family groups. This demographic study investigates the complexities of acorn storage and group living in acorn woodpeckers at Hastings Reservation in central coastal California. It is one of the most thorough studies of any avian social system to date.

This is the first comprehensive field guide to the birds of the West Indies to appear in more than fifty years. It covers all 564 bird species known to occur in the region (including migrants and infrequently occurring forms). Each species is represented by a full description that includes identification field marks, local names, status, habitat, voice, nesting, range, and comments about the bird. A map showing the bird's distribution accompanies each species account. Plumages of all species are depicted in eighty-six beautifully rendered color plates. Twelve of these plates feature...
