Glossy Black Cockatoo - Calyptorhynchus Lathami
The glossy black cockatoo (Calyptorhynchus lathami), is the smallest member of the subfamily Calyptorhynchinae found in eastern Australia. Adult glossy black cockatoos may reach 19.5 in in length. They are sexually dimorphic. Males are blackish brown, except for their prominent red tail bands; the females are dark brownish with some yellow spotting. Three subspecies are recognized.
The glossy black cockatoo's closest relative is the red-tailed black cockatoo; the two species form the subgenus Calyptorhynchus within the genus of the same name. They are distinguished from the other black cockatoos of the subgenus Zanda by their significant sexual dimorphism and calls of the juveniles; one a squeaking begging call, the other a vocalization when swallowing food.
C. l. lathami: (rare) The eastern subspecies found between southeastern Queensland and Mallacoota in Victoria.
C. l. erebus: Occurs in central Queensland from Eungulla near Mackay south to Gympie.
C. l. halmaturinus: (endangered) The Kangaroo Island subspecies has been listed by the Australian Government as endangered.
Like the related red-tailed black cockatoo, this species is sexually dimorphic. The male glossy black cockatoo is predominantly black with a chocolate-brown head and striking caudal red patches. The female is a duller dark brown, with flecks of yellow in the tail and collar. The female's tail is barred whereas the male's tail is patched. An adult will grow to be about 46–50 cm (18–19.5 in) in length. The birds are found in open forest and woodlands, and usually feed on seeds of the she-oak (Casuarina spp.)
