Gang Gang Cockatoo (Callocephalon fimbriatum)

short-tailed stocky cockatoo with a grey body and scarlet head, cheek and fuzzy crest. This is the male of the species and it was spotted another with a grey head and crest which was probably a female. The back feathers have a pale edge giving them a barred appearance. The belly feathers of the female have a scarlet edge which to me looks like dying out embers - an attractive feature. The two were seen grooming each other.
Spotted on tall gum trees near their nesting hollow in a nature reserve.
