Major Mitchell Cockatoo 4
"Few birds more enliven the monotonous hues of the Australian forest than this beautiful species whose pink-coloured wings and flowing crest might have embellished the air of a more voluptuous region" - Major Sir Thomas Mitchell.
Wikipedia says: "Where Galahs readily occupy cleared and part-cleared land, Major Mitchell's Cockatoo requires extensive woodlands, particularly favouring Callitris, Allocasuarina and Eucalyptus." Which is exactly where this pair were, in a small piece of remnant woodland made up of Callitris, Allocasuarina and Eucalyptus. Nice to see theory coincide with what you find in the field.
As PB says, this is the male.
