An unusual case of lead poisoning in a honey buzzard (Pernis apivorus).

The diagnosis and treatment of a case of lead poisoning in a honey buzzard (Pernis apivorus) are described. Presenting signs were diarrhoea and weakness. Lead poisoning was suspected after radiography and confirmed by measuring the lead concentration in a venous blood sample. Comparison values of venous lead concentrations in healthy racing pigeons (Columba livia) were established. A method for the removal of lead shor from the gizzard of birds with a bronchoscope and grasping forceps under fluoroscopic control is described.
