Companion Parrot Beak and Feather Disease: Welfare and Prevention

Psittacine beak and feather disease (PBFD) is a serious viral infection in parrots causing significant welfare harm. Prevention through testing and quarantine protects both individual birds and collections.

Key Facts

PBFD is caused by circovirus and affects over 60 parrot species
The virus causes feather deformity, beak lesions, and immunosuppression
Infected birds become susceptible to secondary infections and die within months to years
There is no cure; prevention through quarantine of new birds is essential
PBFD is widespread in wild populations in Australia and has spread through the pet trade
Testing new birds before introduction protects existing collections

Welfare Considerations

PBFD causes progressive suffering as feathers fail to develop normally and the immune system collapses. Affected birds cannot regulate temperature, preen effectively, or exhibit normal social behaviours. Secondary infections cause additional suffering in immunocompromised birds. The welfare case for testing and quarantine is strong. Responsible breeders test all stock, but the trade in untested wild-caught and poorly monitored captive-bred birds continues to spread disease.

What You Can Do

Ensure new parrots are PBFD tested before introduction to existing birds
Source parrots from breeders who routinely test their breeding stock
Support campaigns for PBFD testing requirements in parrot import and sale regulations
