Occasional respites in the weather offer at least temporary relief from the bushfires a full assessment of the status of the Kangaroo Island subspecies and its supporting ecosystem will take place after the ongoing bushfire crisis has passed. As of 6 January 2020, at least 170,000 hectares (one third of the island's area) had burnt. In early 2020, during the 2019-2020 Australian bushfire season, bushfire warnings were issued for the entirety of Kangaroo Island, giving rise to warnings from scientists that the continued viability of this subspecies in the wild might be doomed as its drooping she-oak food supply undergoes destruction by the fires. It holds the cones in its foot and shreds them with its powerful bill before removing the seeds with its tongue. It feeds on the drooping she-oak ( Allocasuarina verticillata) and the sugar gum ( Eucalyptus cladocalyx) In particular, the bird specialises in the most recent season's cones of Allocasuarina verticillata over older cones of that species and Allocasuarina littoralis. Restricted to the northern and western parts of the island, the population was as low as 158 individuals at one point but recovered to about 370 in 2019. halmaturinus: (endangered) The Kangaroo Island subspecies has been listed by the Australian Government as endangered. erebus: Occurs in central Queensland from Eungulla near Mackay south to Gympie It is associated with casuarina woodland. lathami: (rare) The eastern subspecies found between southeastern Queensland and Mallacoota in Victoria, with isolated pockets in Eungella in central Queensland and the Riverina and Pilliga forest. in 1993, although parrot expert Joseph Forshaw has reservations due to their extremely minimal differences. The three subspecies were proposed by Schodde et al. They are distinguished from the other black cockatoos of the genus Zanda by different tail colour and head pattern, significant sexual dimorphism, and differences in two juvenile call types, a squeaking begging call and a vocalization when swallowing food. The glossy black cockatoo's closest relative is the red-tailed black cockatoo the two species form the genus Calyptorhynchus. The scientific name honours the English ornithologist John Latham. The glossy black cockatoo was first described by Dutch naturalist Coenraad Jacob Temminck in 1807.
