Abstract

Two wild and two captive sandhill cranes (Grus canadensis) were diagnosed by National Wildlife Health Laboratory personnel as having died from lead toxicity. Ingestion of lead fishing weights by the wild cranes and of unspent .22 caliber shell cartidges by the captive cranes were responsible for these deaths. One crane force-fed lead pellets showed an increase of blood lead levels from 0.77 ppm to 23.8 ppm (wet weight) just before its death 15 days following exposure. Liver lead concentrations of sandhill cranes dying of causes other than lead toxicity are presented.
