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.

This bibliography lists 261 references on the food habits of nine North American blackbird species (Icteridae) and on related subjects such as examination techniques, seed dispersal, and sources of bias. The references, which include those published through 1974, are listed alphabetically by author, and brief annotations are given for most of them.

"The basis for this book began twenty years ago when I enrolled in the College of Charleston's summer archaeological field school. After spending the first half of the semester honing our technique by digging five-foot by five-foot units, identifying soil stratigraphy, and collecting artifacts at the Charleston Museum's Stono Plantation, the archaeologists reoriented us students to a new site. For the remainder of the field school we investigated Willtown Bluff on the Edisto River, an early-eighteenth century township surrounded by plantations. My interest in inland rice cultivation grew from our work at the James Stobo site, a 1710 plantation located on the edge of the Willtown township and one mile from the tidal river. For three archaeological seasons between 1997 and 1999, I participated in excavations of the Stobo Plantation house foundation located on a hardwood knoll surrounded by a sea of low-lying Cypress wetlands. During this time, I had a unique opportunity to walk off the dry terra firma and explore miles of inland rice embankments sprawling to the east and to the south of the house site. Major embankments traverse the wetlands on a magnetic north/south and east/west axis, intersected by smaller check banks and drainage canals as far as the eye can see under the dense cypress and hardwood canopy"--

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.

« This report is a compilation and analysis of the results of nearly 10 years of testing the lethal dietary toxicities of pesticidal and industrial chemicals to young bobwhites (Colinus virginianus), Japanese quail (Coturnix c. japonica), ring-necked pheasants (Phasianus colchicus), and mallards (Anas platyrhynchos). A total of 131 compounds were tested. » --

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.
