A birder's history of one of Canada's most famous birding spots Birding at Point Pelee traces Point Pelee's story from the 1870s, to the national park's establishment in 1918, to present day, when as many as 50,000 birders visit the park in May during spring migration. The book portrays the backdrop against which the park was evolving, the scientific discoveries and changes in ornithological methods through the decades -- early specimen-collecting, bird banding, the development of binoculars and telescopes, the growth of nature photography, the shift from birding as science to birding as hobby -- as well as philosophical shifts and debates about amateur versus professional credentials, and the balance to strike between conservation and recreation. Thoroughly researched and lively, the story takes readers from the earliest days, when the birders were few but fervent, to today's international tourism phenomenon.

This book discusses emerging advances in HIV-AIDS management to support strategies for control and elimination.
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.

This book represents the proceedings of the firstGreat Lakes Costal Wetlands Colloquium (November 5-7, 1984; East Lansing, Michigan). The theme wasNatural and Manipulated Water Levels in Great Lakes Wetlands. This material constitutes both Great Lakes wetlands and the state of understanding about them. It is intended to provide fisheries and wildlife biologists, ecologists, aquatic resource managers and planners and environmental scientists information about the coastal wetlands in regard to eight priority areas. The colloquium and publication of the proceedings were cosponsored by Sea Grant Program and Environment Canada.
