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 2019-02-14 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.

To provide an introduction to the state’s major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.

Brauning provide a wealth of information for both the professional ornithologist and the amateur birder. This book treats all 428 species seen in the state, including breeding and wintering birds, migrants, and vagrants. Each entry provides the general status of a species; the locations where it is most commonly found; its natural habitat, migratory patterns, breeding habits, and seasonal status and distribution; and a summary of the bird's history in Pennsylvania. With clear descriptions of physiographic regions as well as 44 breeding distribution maps for the most commonly seen birds and 67 photographs of many rare and hard-to-find species, this volume is an indispensable resource about Pennsylvania's bird life.

Available in PDF, EPUB and Kindle. Book excerpt: This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

Download or read book The Iowa Breeding Bird Atlas written by Laura Spess Jackson and published by University of Iowa Press. This book was released on 1996 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Iowa Breeding Bird Atlas"—the first comprehensive statewide survey of Iowa's breeding birds—provides a detailed record of the composition and distribution of the avifauna of the Hawkeye State. The atlas documents the presence of 199 species, 158 of which were confirmed breeding. This landmark volume will alert Iowans to the limited distribution of numerous species and serve as a guide to the management practices—such as forest and wetland management, set-aside programs, reduction in farm chemical use, and crop diversity—which could help insure that many future changes are positive ones. "The Iowa Breeding Bird Atlas" provides a welcome and much-needed baseline for future comparisons of changes in Iowa's birdlife and, by extension, the lives of all animals in the state.
