title: Lead poisoning in sandhill cranes.
abstract: Seven Florida sandhill cranes (Grus canadensis pratensis) and 6 greater sandhill cranes (Grus canadensis tabida) were exposed to lead-base paint containing 27% lead. One bird of each subspecies died enroute to the hospital, with a clinical history of anorexia, weakness, and open-mouth breathing of 36 hours' duration. There were no gross lesions, and microscopic lesions were limited to focal hepatic necrosis and hemosiderosis. Two of each subspecies of cranes developed clinical signs of lead poisoning, which included anorexia, weakness, green diarrhea, regurgitation, and open-mouth breathing. Diagnosis of lead poisoning was confirmed on the basis of blood lead concentrations ranging from 146 microgram/100 ml to 378 microgram/100 ml. These 4 cranes were treated successfully with calcium disodium edetate intramuscularly. Seven of the birds remained clinically normal despite high blood lead levels, especially in the greater sandhill cranes.
