Description

A relatively small, dark grey cockatoo, 33 - 36 cm in total length. Feathers are distinctively squarish on the ends, with a lighter coloured margin producing a scalloped appearance. Males have a bright red head and crest. Females have a grey head and crest and the scalloped margins of females breast feathers are reddish - pink.

Distribution

This endangered population is found in the Ku-ring-gai and Hornsby local government areas. The population is believed to be largely confined to an area bounded by Thornleigh and Wahroonga in the north, Epping and North Epping in the south, Beecroft and Cheltenham in the west and Turramurra/South Turramurra to the east. It is known to inhabit areas of Lane Cove National Park, Pennant Hills Park and other forested gullies in the area.

Habitat and ecology

  • Occurs within a variety of forest and woodland types. Usually frequents forested areas with old growth attributes required for nesting and roosting purposes.
  • Also utilises less heavily timbered woodlands and urban fringe areas to forage, but appears to favour well timbered country through which it habitually flies as it moves about.
  • Individuals of this population are likely to move outside the 'defined' population boundary in the general area and should still be considered of this population.
  • Significant as it is the last known breeding population in the Sydney Metropolitan area.
  • Has a small population size, estimated to be between 18 - 40 pairs.
