Pathology of aging psittacines.

Authors: Reavill, Drury R; Dorrestein, Gerry M

Abstract: Aging processes leading to specific organ problems are not obvious in aging psittacines. In general, birds live long and age slowly despite their high metabolic rates and very high total lifetime energy expenditures. Most pathologic processes seen in older parrots are generally not specific for aging because they are seen in young birds as well. Pathologic processes that have a tendency to occur more in older psittacines are atherosclerosis and repeated injury processes, such as chronic pulmonary interstitial fibrosis, pneumoconiosis, liver fibrosis, and lens cataracts. Also, some neoplasms are more often seen at an older age.
