Available in PDF, EPUB and Kindle. Book excerpt: Bald eagle productivity surveys were conducted annually from 1972 through 1980 within Seymour Canal, southeast Alaska. The 56 miles of coastline support roughly 90 nests averaging 30 percent active and 1.58 eggs or downy young per active nest. Productivity dropped precipitously to 19 percent in 1979 and 1980. Nest loss due to natural causes averaged 5 percent per year.

Available in PDF, EPUB and Kindle. Book excerpt: Nest occupancy and reproductive success of the large breeding populations of bald eagles (Haliaeetus leucocephalus) within parks in the Southwest Alaska Network (SWAN), including Katmai National Park & Preserve (KATM), have been selected as a “vital sign” for monitoring as they are indicative of the health of both freshwater and marine ecosystems. Records of nesting activity were collected from 1974-1997 in KATM, but monitoring lapsed from 1998- 2010. In 2011, we reinitiated eagle surveys in KATM following a standardized sampling protocol with an initial double-count aerial survey in May to determine nest locations and occupancy, and a follow-up survey in July to assess productivity. Objectives of this report were to: (1) map all empty and incubating eagle nests located in the Naknek drainage of KATM in 2011, (2) summarize historic KATM bald eagle nesting data, and (3) discuss techniques that can be used for future consistent monitoring.

Book excerpt: 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.
