This report serves as a source manual of raptors occurring on Army Corps of Engineers lands in the Pacific Northwest. It consists primarily of a comprehensive literature review covering aspects of the biology of 35 species of eagles, hawks, falcons, vultures, and owls. The manual was developed to provide biologists and resource managers with background information to facilitate the application of sound raptor management practices on project lands. While the literature is cosmopolitan, references are applicable to species found in, but not limited to, the Pacific Northwest. Approximately 4,000 citations, compiled through 1983, are included. General guidelines on raptor management and survey techniques are provided. An outline of techniques is given for habitat assessment, development, and management applicable to Federal lands, and recommendations are provided for management needs regarding various land use practices and recreational activities. Basic procedures for conducting raptor nesting surveys, migration counts, and winter surveys are outlined. Raptor studies conducted on project lands in the US Army Engineer Division, North Pacific, are summarized.
