| clinal genetic variation at enzyme loci in bald eagles (haliaeetus leucocephalus) from the western united states. | five polymorphic enzyme loci of about 50 sampled were discovered in blood extracts of bald eagles from alaska, washington, oregon, and arizona, representing the first biochemical genetic variation described for the species. all five loci exhibited trends of north-to-south clinal geographic variation in gene frequencies. gene frequencies at three loci culminated in fixation in the arizona population, which consists of 12 known breeding pairs. the arizona birds were maximally heterozygous at the o ... | 1985 | 4015622 |
| lead poisoning of bald (haliaeetus leucocephalus) and golden (aquila chrysaetos) eagles in the u.s. inland pacific northwest region--an 18-year retrospective study: 1991-2008. | to determine risk factors and seasonal trends of lead poisoning in bald (haliaeetus leucocephalus) and golden (aquila chrysaetos) eagles, blood lead levels were evaluated in eagles admitted from the inland pacific northwest region of the united states to the raptor rehabilitation program, college of veterinary medicine at washington state university from 1991 to 2008. admissions were from washington (32 bald eagles, 27 golden eagles), northern idaho (21 bald eagles, 25 golden eagles), northeaste ... | 2010 | 21302758 |
| polybrominated diphenyl ethers in bald (haliaeetus leucocephalus) and golden (aquila chrysaetos) eagles from washington and idaho, usa. | little is known about the exposure and accumulation of polybrominated diphenyl ethers (pbdes) in the 2 species of eagles inhabiting north america. the authors analyzed the livers of 33 bald eagles and 7 golden eagles collected throughout washington and idaho, usa, for 51 pbde congeners. total pbdes ranged from 2.4 ng/g to 9920 ng/g wet weight. bald eagles and eagles associated with large urban areas had the highest pbde concentrations; golden eagles and eagles from more sparsely populated areas ... | 2014 | 25367115 |
| a capture to remember: monitoring the health of avian scavengers on the pacific coast. | because of concern over risks to the health of avian communities on the washington and oregon coasts, the nonprofit coastal raptors and other partners initiated a study where, to date, coastal raptors has live-captured and sampled 27 bald eagles (haliaeetus leucocephalus), 27 turkey vultures (cathartes aura), and 6 common ravens (corvus corax) for contaminants and disease study. in this article, the author highlights the events of one of the nearly 100 days on which trapping has occurred. an adu ... | 2015 | 26378672 |
