MetadataShow full item record
A wildlife species account for the osprey (Pandion haliaetus) is provided as Section 4.3.1 of the U.S. Army Corps of Engineers Wildlife Resources Management Manual. The account is developed as a guide to provide the biologist or resource manager with basic information on the biology, distribution, ecology, and management of the osprey. Major topics covered include status, characters and measurements, population attributes, distribution and abundance, habitat requirements, management, and census and sampling. The status of the osprey in the United States is described, and the importance of the species as an environmental indicator is discussed. The section on population attributes includes details on breeding biology, migration, dispersal of young, mortality, and impact of pesticides. The present nesting population in the contiguous United States is estimated at approximately 8000 pairs. The status of nesting populations is described regionally for the Pacific Northwest, Western Interior, Great Lakes, Atlantic Coast, and Florida and the Gulf Coast. The ecological requirements of ospreys and their association with marine environments, rivers, lakes, and reservoirs are discussed. Management objectives and strategies are presented, and basic procedures for conducting population surveys are described.
