Gang –gang cockatoos range through south eastern Australia. They spend the warmer months at higher altitudes and we see them in autumn and winter when they move downland. The male (top) has red head feathers whilst the female (see left) does not.
This pair (below), a male (red crest) and younger male (red crest not so much in evidence), were feeding in a eucalypt in the warm June sunshine at the Edward Hunter Heritage Bush Reserve.
We were alerted to their presence not by their call, which apparently sounds like a rusty gate, but by a rain of falling gumnut debris. They looked down at us, continuing to feed, but did not oblige with a clear side view.
Gang-gangs, Callocephalon fimbriatum, pair for life. Breeding takes place between October and January with birds often returning to the same tree each year. They’re omnivores, eating from introduced and native vegetation as well as insects.
