Gang-gang Cockatoo
Callocephalon fimbriatum
The gang-gang cockatoo is 32–37 cm (13–15 in) in length with a 62–76 cm (24–30 in) wingspan, and weighs 230–334 grams. They are grey birds with wispy crests. The head and crest are bright red in males, but dark grey in females. The edges of feathers in the underparts have edges of yellow or pink. The edges of feathers on the upperparts are slightly paler grey than the rest of the feather, which makes the bird look somewhat barred. Juvenile males can be distinguished by their brighter crowns and shorter crests, but otherwise look similar to the adult female.

Glossy Black Cockatoo
Calyptorhynchus lathami
Like the related red-tailed black cockatoo, this species is sexually dimorphic. The male glossy black cockatoo is predominantly black with a chocolate-brown head and striking caudal red patches. The female is a duller dark brown, with flecks of yellow in the tail and collar. The female's tail is barred whereas the male's tail is patched. An adult will grow to be about 46–50 cm (18–19.5 in) in length.
