Psittacine Beak and Feather Disease (PBFD)
What is it?
PBFD is a viral disease (circovirus) affecting parrots, especially cockatoos, African greys, and lovebirds. It damages feathers, beak, and the immune system and is highly contagious via feather dust and droppings.
What signs should I watch for?
Signs to watch for include abnormal, pinched, or missing feathers; lack of powder down; overgrown, cracked, or fragile beak; and recurrent infections.
How is it diagnosed and treated?
PCR testing of blood or feathers confirms infection. There is no cure; care is supportive.
Can it be prevented, and what's the outlook?
- Some birds clear the virus, but many are affected for life.
- Test and quarantine new birds and keep infected birds apart.
