Book excerpt: The North American Breeding Bird Survey (BBS) is run by approximately 2,000 skilled amateur ornithologists and is coordinated cooperatively by the U.S. Fish and Wildlife Service and the Canadian Wildlife Service. Since 1966. BBS cooperators have been collecting standardized information on North American bird populations. The BBS is a roadside survey, comprised of permanent routes that are surveyed yearly. Each route is 39.4 km (24.5 miles) long and consists of 50 stops spaced 0.8 km (0.5 mile) apart. All birds heard or seen during a 3-min observation period at each stop are recorded, and, for each species, the sum of the counts on individual stops is used as an index of species density on the route. Survey routes occur throughout the continental United States and most of Canada (see map in Droege and Sauer 1989). Here, we present the population changes of the 251 bird species reported on the 50 or more BBS routes in the survey region during 1988 and 1989. Population trends for 1966-89 are presented for comparison. The direction and significance of population changes between the years for the 306 species occurring on 10 or more routes within States arid Provinces are summarized in Appendix B. The pattern of population changes for selected species is graphically summarized on maps by physiographic stratum (Droege and Saner 1959). Detailed State, provincial, and physiographic strata changes are available to interested readers.

Book excerpt: "The North American Breeding Bird Survey (BBS) has been the cornerstone of continental bird conservation and management for hundreds of North American bird species in the United States and Canada for more than 50 years. This strategic plan was developed in collaboration with key partners and stakeholders and charts the ambitious course for the BBS over the next decade (2020-30). Using this plan as a guide, the BBS program will set out to improve the breadth and depth of standardized data collection and analytical products; ensure its products are widely used and recognized as the authoritative source for long-term population change information for most birds; and secure adequate resources, internally and through partnerships, to realize the expanded vision of the BBS intended to support avian management needs through 2030"--

This book was released on 2017-09-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category The various species of new world blackbirds, often intermingled in large foraging flocks and nighttime roosts, collectively number in the hundreds of millions and are a dominant component of the natural and agricultural avifauna in North America today. Because of their abundance, conspicuous flocking behavior, and feeding habits, these species have often been in conflict with human endeavors. The pioneering publications on blackbirds were by F. E. L. Beal in 1900 and A. A. Allen in 1914. These seminal treatises laid the foundation for more than 1,000 descriptive and experimental studies on the life histories of blackbirds as well as their ecology and management in relation to agricultural damage and other conflicts such as caused by large winter roosting congregations. The wealth of information generated in over a century of research is found in disparate outlets that include government reports, conference proceedings, peer-reviewed journals, monographs, and books. For the first time, Ecology and Management of Blackbirds (Icteridae) in North America summarizes and synthesizes this vast body of information on the biology and life histories of blackbirds and their conflicts with humans into a single volume for researchers, wildlife managers, agriculturists, disease biologists, ornithologists, policy makers, and the public. The book reviews the life histories of red-winged blackbirds, yellow-headed blackbirds, common grackles, and brown-headed cowbirds. It provides in-depth coverage of the functional roles of blackbirds in natural and agricultural ecosystems. In doing so, this authoritative reference promotes the development of improved science-based, integrated management strategies to address conflicts when resolutions are needed.

Available in PDF, EPUB and Kindle. Book excerpt: Reaching from interior Alaska across Canada to Labrador and Newfoundland, North America’s boreal forest is the largest wilderness area left on the planet. It is critical habitat for billions of birds; more than 300 species regularly breed there. After the breeding season, many boreal birds migrate to seasonal habitats across the United States, Mexico, the Caribbean, and Central and South America. This volume brings together new research on boreal bird biology and conservation. It highlights the importance of the region to the global avifauna and to the connectivity between the boreal forest and ecoregions throughout the Americas. The contributions showcase a unique set of perspectives on the migration, wintering ecology, and conservation of bird communities that are tied to the boreal forest in ways that may not have been previously considered.

Available in PDF, EPUB and Kindle. Book excerpt: We used the North American Breeding Bird Survey to estimate trends of red-winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), brown-headed cowbirds (Molothrus ater), and starlings (Sturnus vulgaris) for 1966-76 in the United States and Canada. Extended to a continental scale, the survey indicated significant increases in the mean number of redwings, cowbirds, and starlings observed per route. Starlings had the greatest increase, 4.96 birds per route or a 19.4% increase. The starlings' greatest regional increases occurred in the western United States. Populations of redwings increased most in the St. Lawrence Valley and parts of the Midwest and Lower Plains regions. Cowbirds increased the most in the plains from Iowa to Saskatchewan and decreased over parts of the eastern and midwestern United States. Grackle populations indicated no change on a continental scale but did show strong increases in the Midwest and Lower Plains regions and declines in Appalachia. This knowledge of blackbird and starling population trends in specific areas should improve our ability to understand increasing bird-man conflicts, to evaluate proposed bird-damage control strategies, and to develop more effective, long-term solutions than are available at present.

Available in PDF, EPUB and Kindle. Book excerpt: This volume updates and expands a portion of P. A. Johnsgard's 1975 Waterfowl of North America. It includes two species of the perching duck tribe Cairinini: the muscovy duck and the wood duck, which forage on the water surface but perch in trees and nest in elevated tree cavities. It also includes the dabbling, or surface-feeding, duck tribe Anatini, that forage on the water surface but nest on the ground. The species that breed in North America include the familiar mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided. Five additional Eurasian and West Indian species that have been reported in North America have also been included with more abbreviated accounts. The updated bibliography contains more than 1,000 references. There are 12 maps, 31 drawings, 28 photos, and 58 anatomical or behavioral sketches.

This book was released on 2014-09-05 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats. The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover: The changing abundance of cowbirds and the ways in which their numbers can be estimated. Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior. Behavioral interactions between cowbirds and specific host species. Patterns of cowbird abundance and host use across varying landscapes. Management programs designed to control cowbirds and protect threatened songbirds.

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.
