Psittacine beak and feather disease was first described in the early 1980s and has become recognised as the dominant viral pathogen of psittacine birds worldwide. In wild red-rumped grass parakeets (Psephotus haematonotus), a case of feather loss syndrome that was highly suggestive of PBFD was first recorded in South Australia in 1907. [2]
