History
The first report of featherless, dirty-looking birds in Australian bush was in 1907 by Edwin Ashby. He described apparently PBFD-infected Red-rumped Parrots in the Adelaide Hills, South Australia in 1888.
The condition is more prevalent in widely occurring Australian species such as the Sulphur-crested Cockatoo, Little Corella and Galah.
At one time, Australian birds with PBFD signs were thought to be suffering from a condition caused by an exclusive sunflower seed diet, which is often the main source of food for Australian cockatoos in captivity. This is now known to be false.
The first case of chronic PBFD was reported in a Control and Therapy article in 1972 for the University of Sydney by Ross Perry FACVSc (Avian health), in which he described it as "Beak Rot in a Cockatoo". Dr. Perry subsequently studied the disease and wrote extensively about its clinical features in a range of psittacine birds in a long article in which he named the disease "Psittacine Beak and Feather Disease Syndrome" (PBFDS). This soon became known as Psittacine Beak and Feather Disease (PBFD).

Famous quotes containing the word history:
“Universal history is the history of a few metaphors.”
—Jorge Luis Borges (1899–1986)
“The myth of independence from the mother is abandoned in mid- life as women learn new routes around the mother—both the mother without and the mother within. A mid-life daughter may reengage with a mother or put new controls on care and set limits to love. But whatever she does, her child’s history is never finished.”
—Terri Apter (20th century)
“There is no example in history of a revolutionary movement involving such gigantic masses being so bloodless.”
—Leon Trotsky (1879–1940)
