Psittacine Circoviral (beak and feather) Disease

Just observed a Sulfur Crested Cockatoo with minimal feathers, deformed,
cracked and huge beak, being chased by a cluster of Noisy Miners, Magpies,
Currawong, Ravens and Butcherbirds. Very disturbing sight I must say, with
the bird looking so odd with its grey skin visible, bearing very few
feathers at all on the head or body, and with very few on the wings but
presumably just enough to ensure "flight".

At first I thought the bird was a raptor because of size and the response
of the Noisy Miners in particular: closer examination revealed one very
ill-looking Cockatoo who flew off in the direction of large roosting
colonies of Sulfur Crested Cockatoo and Corella in Blackbutt Reserve at
Kotara, a green forest oasis in a suburb nearby.

Anyone else witnessed/noticed the agitation reaction of other species to
infected Psittacines?
