| secondary poisoning of eagles following intentional poisoning of coyotes with anticholinesterase pesticides in western canada. | records of eagles, coyotes (canis latrans), and red foxes (vulpes vulpes) necropsied at the western college of veterinary medicine, saskatoon, saskatchewan, canada, between 1967 and 2002 were reviewed for cases suggestive of anticholinesterase poisoning. from 1993 to 2002, 54 putative poisoning incidents involving 70 bald eagles (haliaeetus leucocephalus) and 10 golden eagles (aquila chrysaetus) were identified. of these, 50 incidents occurred in saskatchewan, two were in manitoba, and one occur ... | 2004 | 15362815 |
| mercury risk to avian piscivores across western united states and canada. | the widespread distribution of mercury (hg) threatens wildlife health, particularly piscivorous birds. western north america is a diverse region that provides critical habitat to many piscivorous bird species, and also has a well-documented history of mercury contamination from legacy mining and atmospheric deposition. the diversity of landscapes in the west limits the distribution of avian piscivore species, complicating broad comparisons across the region. mercury risk to avian piscivores was ... | 2016 | 26996522 |
| hemograms for and nutritional condition of migrant bald eagles tested for exposure to lead. | plasma proteins, hematocrit, differential blood counts were examined and nutritional condition was estimated for bald eagles (haliaeetus leucocephalus) trapped (n = 66) during antumn migration, 1994-95 at galloway bay (saskatchewan, canada), for the purposes of estimating prevalence of exposure to lead. sex and age differences in hematocrit and plasma proteins were not observed; however, female eagles exhibited larger median absolute heterophil counts than males. hematologic values were similar ... | 2001 | 11504222 |
| a comparison of blood lead levels in bald eagles from two regions on the great plains of north america. | the connection between bald eagles (haliaeetus leucocephalus) and the consumption of waterfowl, lead shotshell pellet ingestion, and subsequent lead exposure is well documented in the united states and is presumed also to be widespread in canada. we compared blood lead concentrations in samples from bald eagles ranging in age from 0.5- to 1.5-yr-old at galloway bay, saskatchewan, canada (n = 97) during october-november, 1992-95 and hauser lake, montana, usa (n = 81) during october-december, 1990 ... | 1998 | 9813839 |
