Birds of Oregon A General Reference

Birds of Oregon is the first complete reference work on Oregon's birds to be published since Gabrielson and Jewett's landmark book in 1940. Five years in the making, this comprehensive volume includes individual accounts of the 485 species now known to occur in Oregon (about 150 more than in 1940), including detailed accounts of the 350 species that regularly occur and briefer accounts of another 135 species that are considered vagrants and wanderers, and thus accidental in Oregon. A separate chapter covers extirpated and questionable species as well as those which have been introduced but have not become established.Oregon is long overdue for a book of this kind. Although northern states generally support fewer species of birds than more southerly ones, Oregon ranks fifth behind only Florida, New Mexico, Texas, and California in terms of numbers of species. This is due to its varied climate, its wide range of habitats, and the mild winters over much of the state, which make it an important wintering area.Birds of Oregon is not a field guide for identifying birds, although it describes the appearance and any unique or special characteristics of each species, and approximately 100 species are illustrated with attractive line drawings. Instead, it compiles and presents in a single large volume what is known today about the population status and distribution of each species, as well as their habitat requirements and diet, their seasonal activities and behavior, where and how they might be found, and any conservation problems. It includes about 200 range maps that reflect the work of more than 700 volunteers who participated in the Oregon Breeding Bird Atlas project, as well as othersources. Subspecies -- of which Oregon has many because of the variability of the state's avian habitats -- are listed with their ranges, thus providing the first accounting of subspecies in the state since 1957.In additiMarshall, David B. is the author of 'Birds of Oregon A General Reference' with ISBN 9780870714979 and ISBN 087071497X.
