Avian Bornavirus was discovered in the summer of 2008. It is a virus exclusive to members of the psittacine
family, and is believed to be the precursor to PDD
in affected parrots
As of yet, it is unknown how Avian Bornavirus spreads amongst birds, and there is no treatment for the disease it causes. If you suspect that your bird may have PDD, contact an avian veterinarian
Scientists identified Avian Bornavirus in over 70% of samples collected from birds infected with PDD.
