USGS National Wildlife Health Center necropsy and contaminant results for bald and golden eagles collected in 8 States from January 1, 2014, through December 31, 2017 to determine cause of illness/death and lead, mercury, and anticoagulant rodenticide exposure
The U.S. Geological Survey National Wildlife Health Center (NWHC) measured environmental contaminants in bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) to evaluate dietary exposure to lead, mercury, and anticoagulant rodenticides (AR), which was identified by U.S. Fish and Wildlife Service (USFWS) as a priority issue of concern for the Mountain Prairie Region 6. Carcasses of bald eagles (n = 172) and golden eagles (n = 142) collected from North and South Dakota, Montana, Wyoming, Colorado, Utah, Nebraska, and Kansas between 2014-2017 were assessed for cause of death and liver lead, mercury, and AR levels. Trauma, electrocution, and lead poisoning were the 3 leading causes of death,...
Anticoagulant rodenticide concentrations in blood and tissue of California condors and turkey vultures (ver. 2.0, May 2023)
The dataset includes specifics on liver tissue and blood plasma anticoagulant rodenticide concentrations measured using high-performance liquid chromatography-tandem mass spectrometry. This data release supersedes Herring, G., and Eagles-Smith, C.A., 2022, Anticoagulant rodenticide concentrations in blood and tissue of California condors and turkey vultures: U.S. Geological Survey data release, https://doi.org/10.5066/P9NHPLHX.

This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels exposed to the second-generation anticoagulant rodenticide brodifacoum (BROD). The goal of the study was to determine the toxic range of brodifacoum by feeding birds a diet containing 0.3, 1.0, or 3.0 ug BROD/g wet weight. Birds were necropsied and examined grossly for hemorrhages or anemia, and liver, kidney, heart, pectoral muscle, and intestine was collected for histopathological evaluation. Tissues were scanned at least 100x magnification and all lesions, including hemorrhage, inflammation, and degenerative changes, were described and assigned a morphologic diagnosis with severity,...
Anticoagulant rodenticide exposure in Barred Owls (Strix varia) collected in Washington and Oregon 2015-2017
This dataset includes anticoagulant rodenticide (AR) screening results of 40 Barred Owls (Strix varia) collected in forested landscapes of Washington and Oregon from 2015-2017. Liver tissue was collected from each owl and screened for exposure to eight AR compounds, including 4 first-generation ARs (warfarin, diphacinone, chlorophacinone, and coumachlor), and 4 second-generation ARs (brodifacoum, bromadionlone, difethialone, and difenacoum). Additionally, this dataset includes geographic, temporal, environmental, and biological attributes of individual owls that were identified as potential sources of variation in AR exposure and/or useful measurements for assessing AR exposure risk of sympatric northern spotted...
Assessing Exposure, Physiological Effects, and Geographic Scope of Anticoagulant Rodenticides in the Critically Endangered California Condor
-Test subject identification information (sample collection site and date, test subject identification number, and sample number) -Clotting time parameters and comments (prothrombin time, Russell’s viper venom time, fibrinogen concentration, and coefficient of variation for replicate analyses)
