A survey of causes of mortality in budgerigars (Melopsittacus undulatus).
Lesions found in 257 post mortem examinations of budgerigars (Melopsittacus undulatus) are recorded. The commonest disease was neoplasia, principally of the gonads, kidneys and fat. Hepatitis and focal hepatic necrosis, thyroid dysplasias and septicaemias were also common. A great variety of other disease processes occurred; each affected only a few birds.
