Beak and Feather Disease Virus (BFDV) is a virus that primarily affects psittacine birds, such as parrots and cockatoos. It causes a range of symptoms, including feather loss, beak deformities, and immune system suppression. The virus is highly contagious and can spread through direct contact or contaminated environments. Infected birds may show signs of illness, but some can be asymptomatic carriers. There is no specific treatment for BFDV, making prevention crucial. Keeping birds in clean environments and monitoring their health can help reduce the risk of infection and protect vulnerable populations.
