Download or read book Population Trends of Blackbirds and Starlings in North America 1966 76 written by Richard A. Dolbeer and published by . This book was released on 1978 with total page 108 pages. 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.

Download or read book Birds of British Columbia Volume 4 written by Wayne Campbell and published by UBC Press. This book was released on 2001-02-23 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much-awaited final volume of The Birds of British Columbia completes what some have called one of the most important regional ornithological works in North America. It is the culmination of more than 25 years of effort by the authors who, with the assistance of thousands of dedicated volunteers throughout the province, have created the basic reference work on the avifauna of British Columbia. Volume 4 covers the last half of the passerines and describes 102 species, including the warblers, sparrows, grosbeaks, blackbirds, and finches. The text builds upon the authoritative format of the previous volumes and is supported by hundreds of full-colour illustrations, including detailed distribution maps, unique habitat shots, and beautiful photographs of the birds, their nests, eggs, and young. In addition, a species update lists and describes 27 species of birds new to the province since the first three volumes were published. The book concludes with Synopsis: The Birds of British Columbia into the 21st Century, which synthesizes data and information from all four volumes and looks at the conservation challenges facing birds in the new millennium. The four volumes in The Birds of British Columbia provide unprecedented coverage of the region's birds, presenting a wealth of information on the ornithological history, regional environment, habitat, breeding habits, migratory movements, seasonality and distribution patterns of 472 species of birds. It is the complete reference work for birdwatchers, ornithologists and naturalists.
