L. LEUCOCEPHALUS (southern U.S. and Baja California) and H. L. ALASCANUS (northern U.S. and Canada) intergrade broadly in the central and northern U.S. Constitutes a superspecies with H. ALBICILLA (AOU 1998). G5 G5 Secure 2005-03-11 2005-03-11 Widespread distribution in North America; large numbers of occurrences, many of high quality, particularly in Alaska and British Columbia, but suffered great decline in southern and eastern part of range earlier this century; still susceptible to a number of threats, particularly environmental contaminants and excessive disturbance by humans; recent rangewide improvement in numbers and the protection offered by governments prevent it from being ranked any higher. F 10,000 - 100,000 individuals F Gerrard (1983) estimated that Alaska and British Columbia have approximately 48,000 bald eagles. Blood and Anweiler (1991) gave North American estimates of 70,000, with 21,000 in British Columbia. Alaska population is about 30,000, and perhaps almost that many occur in western Canada. Estimated number of breeding pairs in Canada in the early 1990s was 15,000-20,000 (Kirk et al. 1995). The reported number of nesting territories in the lower 48 states in 1990 was 3,014 (Kjos 1990). Population estimates (number of occupied territories) based on the 1990 breeding season survey were as follows: northern states, 1165; Chesapeake Bay, 235; Pacific states, 861; southeastern states, 722; southwestern states, 27; total, 3010 (USFWS 1990). In 1992, there were 149 nesting pairs in New England. NON-BREEDING: The winter count for 1992-1993 was about 400 in Maine, 70 in Massachusetts, 61 in Connecticut, 23 in New Hampshire, 12 in Vermont, and a few in Rhode Island (End. Sp. Tech. Bull. 18(2):20). Winter count in late 1980s yielded about 11,250 bald eagles in the lower 48 states.See Busch (1988) for information on status in the southwestern U.S. See Brown et al. (1988) for status in Sonora, Mexico. E >300 E BREEDING AREA occurrences probably number over 150 in British Columbia and Alaska. The total number of occupied territories (not equivalent to breeding area occurrences) in British Columbia and Alaska is probably at least 7000 (Gerrard 1983); there are about 1000 on Vancouver Island alone (British Columbia CDC 1993). Kjos (1992) estimated there were 3,014 occupied bald eagle territories in the lower 48 states. EF Stable to increasing (+/-10% fluctuation to >10% increase) EF As of early 1990s, populations in many areas had rebounded from the low levels that occurred before DDT use was banned in the U.S. The population increase in recent years has been accomplished through protection and active management, as well as through enhanced reproduction after the DDT ban. Populations have been increasing in the contiguous 48 states: the number of nesting territories nearly tripled between 1980 and 1990 (Kjos 1992). In the lower 48 states, breeding population has doubled every 6-7 years since the late 1970s (USFWS, Federal Register, 12 July 1994, p. 35585). In Alaska and British Columbia numbers have been generally stable at about 48,000 (Gerrard 1983, Campbell et al. 1990). Populations are stable and "healthy" in Alaska and western Canada. As of the early 1980s, most Canadian populations were reasonably stable, and problem populations in southwestern Ontario and the maritime provinces were showing signs of recovery (Brownell and Oldham, 1984 COSEWIC report). Overall, populations have increased in Canada in recent decades (Kirk et al. 1995, Hunter and Baird 1995). A significant increase was recorded in migration counts in northeastern North America, 1972-1987 (Titus and Fuller 1990). The breeding population in the Chesapeake Bay region increased 12.6% per year from 1986 to 1990; the mean minimum survival rate of all eagles was 91%; however, eagle habitat there is being converted to human development at a rapid rate (Buehler et al. 1991). In California in the late 1980s, the winter population was stable, and the breeding population was increasing in numbers and range (California DF&G 1990). Increasing in Arizona in the 1980s (Forbis 1988). DE Moderate decline to relatively stable (25% change to 50% decline) DE String Needs annual or biannual inventory until recovery goals are reached in the U.S. Then inventory could be reduced to longer (5-10 year) intervals at most locations. DE Many to very many (13 to >40) occurrences appropriately protected and managed DE Protected in the United States by the Bald Eagle Protection Act, the Migratory Bird Treaty Act, and the Endangered Species Act. Listed as Endangered or Threatened in the lower 48 States, but proposed to be downlisted to Threatened in all 48 states except portions of the American southwest, and proposed to list eagles in adjacent Mexico as endangered. Protected in Canada by the Migratory Bird Treaty and the Wildlife Act. Protected in Mexico by the Migratory Bird Treaty. Many occurrences are protected in wildlife refuges, National, state, and Provincial parks, private nature reserves, and on some TNC-owned property. Acquisition of breeding territories is always a priority and is necessary for further improvement. Acquisition of other types of protection of winter foraging habitats and winter roosts advisable. E Localized substantial threat Low Moderate Moderate Major threats include habitat loss, disturbance by humans, biocide contamination, decreasing food supply, and illegal shooting (Evans 1982, Green 1985, Herkert 1992). In 1992, many died in northern Utah after eating poisoned bait set out by ranchers. Breeding success still is being affected by environmental contaminants in the diet along Lake Superior in Wisconsin (Kozie and Anderson 1991). Greatest potential threats in Florida include urban development and commercial timber harvest (Wood et al. 1989). The Chilkat Bald Eagle Preserve, Alaska, which supports the largest wintering population anywhere, was threatened by a proposed copper mine in the early 1990s (Ehrlich et al. 1992). See Witmer and O'Neil (1990) for information on estimating cumulative impacts of multiple hydroelectric development and logging activities in Washington. See Montopoli and Anderson (1991) for a model used to evaluate the cumulative effects of selected forms of human disturbance in the Greater Yellowstone ecosystem. As of the mid-1990s, the population in the southwestern U.S. continued to face threats and required intensive management to maintain current population levels (1994 End. Sp. Tech. Bull. 19(5):18). Generally susceptible to human intrusion, but "show a high degree of adaptability and tolerance if the human activity is not directed toward them" (Beebe 1974). However, chronic disturbance results in disuse of areas by eagles (Fraser 1985).
