Summary, Etc. Note: |
Abstract: 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. |

Abstract: Depletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes. |
