This book is an authorized updated and expanded edition of Helen
Downing's Birds of North-Central Wyoming and the Bighorn National Forest
(1990). The Bighorn Mountains in Wyoming are more than 100 miles in
length with a maximum elevation of 13,167 feet. Flanked to the west by
the Bighorn River basin and to the east by the Powder River basin, they
have produced a wide variation of vegetation types and ecosystems,
including native grasslands and coniferous forest. At least 327 bird
species have been reported from the region, and breeding has been
confirmed for 190 species. Species descriptions indicate relative
abundance, breeding status by latilong, and locality/date records.
Regional birding areas are described and mapped, and results of recent
regional breeding bird surveys and seasonal bird counts are summarized.
Line drawings illustrate representatives of each of the 53 avian
families documented for the region, and there are 7 maps and more than
60 literature citations.
