Abstract

Lead poisoning from feeding on carcasses shot with lead‐based ammunition is a well‐known threat to wildlife. Thus, nonlead (e.g., copper‐based) ammunition is promoted as a safe alternative. We present a unique situation of a male California condor (Gymnogyps californianus) discovered with both a lead fragment and a copper bullet in his digestive tract simultaneously. We show that ingestion of a copper bullet did not result in elevated blood copper concentrations, while ingestion of a lead fragment contributed to lead toxicity. Our findings can inform nonlead ammunition outreach efforts by demonstrating that ingestion of a copper‐based bullet did not result in the poisoning of a California condor.

加州秃鹰中毒的铅，而不是铜，当两者摄入:一个案例研究

以含铅弹药射击的尸体为食导致的铅中毒对野生动物是一种众所周知的威胁。因此，无铅(如铜基)弹药作为一种安全的替代品而得到推广。我们提出了一个独特的情况，雄性加利福尼亚秃鹰(Gymnogyps加利福尼亚)发现铅碎片和铜子弹同时在他的消化道。我们表明，摄入铜弹不会导致血铜浓度升高，而摄入铅碎片会导致铅中毒。我们的研究结果可以通过证明摄入铜基子弹不会导致加利福尼亚秃鹰中毒，从而为无铅弹药的推广工作提供信息。
