Acute beak and feather disease in juvenile African Grey parrots--an uncommon presentation of a common disease

Psittacine Beak and Feather Disease is commonly diagnosed all over the world as a viral disease of psittacine birds that primarily results in abnormalities of the feathers and beak. The clinical presentation of this disease varies between species and age groups, but in the majority of cases the course of the disease is chronic. This case report documents an acute form of the disease in African Grey parrots (Psittacus erithacus erithacus) that resulted in death without lesions in the feathers and beak.
