Book Description
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.

Book Description
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.
