Book excerpt: Singing-ground surveys of the American woodcock indicate that breeding populations have increased gradually over the past 7 years while production, as indicated by wing-collection surveys, has remained relatively stable. The woodcock harvest, meanwhile, has probably more than doubled during the past decade. This suggests that while woodcock are probably becoming more important to North American sportsmen, hunting mortality is still relatively unimportant.

Download or read book Wyoming s Ucross Ranch Its Birds History and Natural Environment written by Paul Johnsgard and published by Lulu.com. This book was released on 2019-02-28 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book profiles 60 of the most abundant, characteristic, and interesting birds that have been regularly reported from the Ucross Ranch and the adjacent Powder River Basin. The 20,000-acre Ucross Ranch lies on the western edge of the Powder River Basin of northeastern Wyoming. Ucross is a textbook example of the prairie grassland/shrubland habitat type referred to as the sagebrush steppe, a landscape that is an icon of Wyoming's vast open spaces.We focus especially on those species that occur year-round or are present as breeders during the summer months, and we place emphasis on a unique group of sagebrush steppe-adapted birds.
