Cyanide poisoning of a Cooper's hawk ( Accipiter cooperii)

Abstract

A Cooper's hawk ( Accipiter cooperii) was found dead in a ditch leading from a heap leach pad at a gold mine in Nevada. Observations at autopsy included an absence of external lesions, traces of subcutaneous and coronary fat, no food in the upper gastrointestinal tract, and no lesions in the viscera. Cyanide concentrations (µg/g ww) were 5.04 in blood, 3.88 in liver, and 1.79 in brain. No bacteria or viruses were isolated from tissues, and brain cholinesterase activity was within the normal range for a Cooper's hawk.

Keywords: Blood; Cooper’s hawk; brain; cyanide poisoning; liver.
