These are grey birds with wispy crests.
Adult Sexual Dimorphism

Similar Species Distinction
Gang-gang cockatoos are not easily confused with other cockatoo species, though they may look similar to Galahs when in flight.
Social Behavior and Vocalization
They are very social birds, and are not overly noisy.
Native Range
This species is endemic to coastal regions of south-eastern Australia.
Extirpated Population
It once inhabited King Island off the coast of Tasmania, but is now extinct there.
Introduced Population
It is an introduced species on Kangaroo Island.
Preferred Habitat
Gang-gang cockatoos prefer mountain forests and woodlands with dense shrub understories.
Migration and Breeding Habitat Requirements
They make short-distance migrations to more open habitats in winter, but must return to denser forests to breed, because they require tall trees to build their nests.
