Where do Glossy Black-Cockatoos live?
Habitat
Woodland dominated by Allocasuarina and in open forests. Often confined to remnant Allocasuarina patches surrounded by cleared farmlands.
Distribution
There are three recognised subspecies of the Glossy Black-Cockatoo. The Glossy Black-Cockatoo as it occurs on Kangaroo Island is recognised as subspecies Calyptorhynchus lathami halmaturinus and is a threatened species.
The south-eastern subspecies C. l. lathami found from south-eastern Queensland to eastern Victoria is also a threatened species. A third subspecies found in the coastal areas of central-eastern Queensland is subspecies C. l. erebus.
What do Glossy Black-Cockatoos eat and how do they mate?
Feeding and diet
The Glossy Black-Cockatoo's diet is almost exclusively Allocasuarina seeds.
Breeding behaviours
Quieter and less raucous than other black-cockatoos, they can be detected by the clicking of their bills and the falling debris of casuarina cones and twigs. These birds mate for life, with pairs maintaining their bond all year round. The female prepares the nest hollow and incubates the eggs, only leaving the nest to feed after the newly-hatched nestlings are a week old. Males feed the female and nestlings throughout the incubation and brooding period.
