Kangaroo Island Glossy Black-Cockatoo

Calyptorhynchus lathami halmaturinus is found across 1 electorates.

The Glossy Black-Cockatoo is a medium-sized cockatoo about 48 cm in length and 510 to 515 g in weight, with a wing-span of approximately 90 cm. The adults are mainly black, with black-brown colouring on the head, neck and underbody, and panels of red or orange-red with black bars in the tail. The adult female also has conspicuous yellow patches on the head. These patches are absent from most males, but they may be expressed weakly in a few individuals. Juveniles of the Glossy Black-Cockatoo are similar in appearance to the adult male, but have tiny yellow spots on the head; yellow spots or bars on the breast, belly and flanks; yellow or orange spots on the wing; red or orange-yellow panels with black barring in the tail; a pale grey bill; and a pale pink-grey ring of skin around the eye. The Glossy Black-Cockatoo usually occurs in pairs, or in groups of three, which comprise a breeding pair and their offspring. Solitary males and small groups of juvenile males are also observed, as are loose flocks, which typically consist of 25 birds or less, but may comprise 50 or more birds in the post-breeding period.¹
