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:
“What would we not give for some great poem to read now, which would be in harmony with the scenery,—for if men read aright, methinks they would never read anything but poems. No history nor philosophy can supply their place.”
—Henry David Thoreau (1817–1862)
“Three million of such stones would be needed before the work was done. Three million stones of an average weight of 5,000 pounds, every stone cut precisely to fit into its destined place in the great pyramid. From the quarries they pulled the stones across the desert to the banks of the Nile. Never in the history of the world had so great a task been performed. Their faith gave them strength, and their joy gave them song.”
—William Faulkner (1897–1962)
“The only thing worse than a liar is a liar that’s also a hypocrite!
There are only two great currents in the history of mankind: the baseness which makes conservatives and the envy which makes revolutionaries.”
—Edmond De Goncourt (1822–1896)
