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 The Ecology of a Tallgrass Treasure Audubon s Spring Creek Prairie written by Paul Johnsgard and published by Lulu.com. This book was released on 2018-08-29 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the major plant and animal components of Spring Creek Prairie Audubon Center, an 850-acre National Audubon Society tallgrass prairie in Lancaster County, southeastern Nebraska. In addition to providing a species list of the area's plants (368 species), there are comprehensive annotated lists of its birds (240), mammals (43), reptiles (23), and amphibians (10). There are also variably complete annotated lists of the area's butterflies (76), sphinx moths (30), silk moths (7), dragonflies (24), damselflies (11), grasshoppers (9), katydids (11), mantids (2), and walkingsticks (2). Brief profiles of life histories and ecologies of 55 animal and 7 plant species are included, as well as information on nearly 100 public-access native grasslands in eastern Nebraska. The text comprises more than 68,000 words, 400 references, and a glossary of 125 biological/scientific terms as well as more than 40 line drawings by the author.

Download or read book Birdlife of the Gulf of Mexico written by Joanna Burger and published by Texas A&M University Press. This book was released on 2018-01-02 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf of Mexico is one of the most important ecological regions in the world for birds. The mosaic of diverse habitats in the region provides numerous niches for birds. There are productive salt marshes, barrier islands, and sandy beaches for foraging and nesting; a direct pathway between North and Central and South America for migrating; and warm, tropical waters for wintering. Many species are residents all year around, some migrate through, and still others spend the winter along the shores. The Gulf Coast is home to a significant portion of the world’s population of Reddish Egret and Snowy Plover and a significant portion of the US breeding populations of certain birds, including the Sandwich Tern, Black Skimmer, and Laughing Gull. In total, there are more than 400 bird species that rely on the Gulf at some time during the year. Drawing on decades of fieldwork and data research, renowned ornithologist and behavioral ecologist Joanna Burger provides detailed descriptions of birdlife in the Gulf of Mexico. Burger records trends in bird population, behavior, and major threats and stressors affecting birds in the region, including the effects of the Deepwater Horizon oil spill in 2010. While some of this data exists in journal articles, research papers, and government reports, this is the first volume to weave together a comprehensive overview of the birds and related natural resources found in the Gulf of Mexico. Illustrated with over 900 color photographs, charts, and maps, this landmark reference volume will be immensely important for researchers, conservationists, land managers, birders, and wildlife lovers.

Download or read book The North American Perching and Dabbling Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

Download or read book Neotropical Migratory Birds written by Richard DeGraaf and published by Cornell University Press. This book was released on 2019-06-07 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrushes, warblers, vireos, and tanagers are probably the most familiar of the Neotropical migrants—birds that breed in the United States and Canada, then journey to spend the winter in the Caribbean, Mexico, or southward. But this extraordinary group actually comprises a large number of diverse species, including waterfowl, shorebirds, terns, hawks, flycatchers, and hummingbirds. In their compendious review of information on these birds, Richard M. DeGraaf and John H. Rappole illuminate the need for a thorough understanding of the ecology of each species, one that exte4nds throughout the entire life cycle. The authors argue convincingly that conservation efforts must be based on such an understanding and carried out across a species' range—not limited to the breeding grounds. This book is the first to summarize in one volume much-needed practical data about the distribution and breeding habitat requirements of migratory birds in North and South America. The body of the book consists of natural history accounts of more than 350 species of Neotropical migrants, including a brief description of each bird's range, status, habitats on breeding grounds, nest site, and wintering areas. The authors provide a complete range map of each species' distribution in the Western Hemisphere as well as notes on the distribution—basic data that until recently have largely been unavailable in usable form to ornithologists and land and resource managers. An appendix lists species that are increasing or decreasing at significant rates in various physiographic regions of North America.
