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 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.
