Histopathology of American kestrels (Falco sparverius) exposed to brodifacoum
July 17, 2019
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, chronicity, and distribution as appropriate.

Brodifacoum toxicity in American Kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure
A seminal question in ecotoxicology is the extent to which contaminant exposure evokes prolonged effects on physiological function and fitness. A series of studies were undertaken with American kestrels ingesting environmentally realistic concentrations of the second-generation anticoagulant rodenticide (SGAR) brodifacoum (BROD). Kestrels fed BROD at 0.3, 1.0 or 3.0 µg/g diet wet wt for...
