註釋

This report presents the distribution ecology, management and status of 12 species of raptors, compiled largely from the literature, and an extensive bibliography on each species. Earlier declines in the bald eagle, Cooper's hawk, merlin, osprey, peregrine falcon, and the sharp-shinned hawk appear to have ended with restrictions on organochlorine biocide use, and most populations appear to be recovering. However, continued use of organochlorine biocides in South and Central America has the potential of negating this positive trend.
