Status Of Rare Birds In Montana With Comments On Known Hybrids

Handbook of Avian Hybrids of the World

With more than 5,000 works cited, Handbook of Avian Hybrids of the World is the greatest compendium of information ever published on hybridization in birds. Worldwide in scope, it provides information on all reported avian crosses, not only those occurring in captivity, but also in a natural setting (approximately 4,000 crosses are covered). This book is a basic reference, intended both for the serious birder and the professional biologist. McCarthy's work fills a need for reference material that takes into account the last half century of data. It will be of interest to workers in a wide variety of fields, ranging from animal behavior to genetics, ecology, zoology, and systematics. In fact, it will make fascinating reading for anyone interested in birds and the natural world.

Status of Rare Birds in Montana, with Comments on Known Hybrids

I provide detailed records for 113 bird species of rare occurrence (? 20 records each) in Montana. Twenty-seven of these species are no longer regarded as rare in the state, based on the additional records provided in this paper, and 1 species (Iceland gull [Larus glaucoides]) should be regarded as hypothetical. Ninety-one species not recorded by Saunders (1921) have been documented, including 3 loons, 3 jaegers, 8 gulls, and 18 warblers. I also review the status of 5 "non-rare" species whose abundance and distribution have changed markedly during the 2nd half of this century and discuss hybrids of 16 species pairs.
