bonus...

...to add to the feather collection from a mob of Red Tailed Black Cockatoos yelling and generally carrying on in the eucalyptus trees towering above  our afternoon walk.
They do tend to hangout in the uppermost branches but little miss RTBC (extra) was close enough to see her tail feathers known apparently as the 'Opal' gem of the feather world.

Blimey these sell on ebay for some serious dosh!
Eeeek
