Hornsby Council wants residents to report sightings of the gang-gang cockatoo, which has a scarlet head and slate-grey body.

The council’s environmental scientist Alex Fraser said the bird’s habitat was mainly in the Pennant Hills, Thornleigh, Beecroft, Epping and Cheltenham areas. Similar in size to a galah, they have a call resembling a creaky hinge.

Gang gang cockatoos predominantly feed on plants, fruits, berries, insects and larvae.

“They’re a fascinating creature. They form close, monogamous pairs and nest in the hollows of tall trees,” Mr Fraser said.

The information collected by the council will be used in its biodiversity planning and management.
