Subspecies description
-
Calyptorhynchus lathami lathami
(Temminck, 1807) – The nominal.
-
Calyptorhynchus lathami halmaturinus
(Mathews, 1912) – Medium-size ones 48 cm. length and 510 to 515 weight g, with a wing of approximately 90 cm.. The of adults they are mainly black, dark brown in the head, the neck and the bottom of the body, and Red panels (in males) or orange-red with bars Black (in females) on tail. The female adult is also conspicuous in the head. These patches are absent from most males., Although they can be expressed faintly in a few individuals (Higgins 1999).
The immature are similar in appearance to the male adult, but have small stains yellow in it head; spots or bars yellow in the chest, belly and flanks; yellow or orange spots on the wing (mainly on the bottom); Red or orange-yellow panels with black bars at the tail; One bill pale grey (instead of dark); And a ring of skin around the eye pale grey (instead of grey dark) (Higgins 1999, L. Pedler 2007, com. Pers.).

Areas forested frequently dominated by casuarinas of which are highly dependent for its food. These are small shrubs commonly known as the Sheoaks, wood for beef (Beefwood) or Australian pine. These shrubs are widespread in tropical and subtropical regions.
They are also distributed in open humid forests, difficult terrain where deforestation has not been too great. They have an imperative for natural tree cavities to nest.
Reproduction:
Forman couple during all the life. The couple has relationships throughout the year. This type of family of them parrots prefers to nest in cavities natural of the eucalyptus, whether dead or in full vitality. The nest usually placed at an altitude that ranges between the 3 and 30 meters above the ground. The cavity is filled with leaves and branches. Sometimes, together with other breeding pairs, they share the same tree year after year.
In New South Wales the season extends from March to August. The spawning It consists of a single egg white. It is the female that takes charge of most of the tasks.: It prepares the nest and incubates herself. Never leave the nest until the small is reached the age of one week. In most cases, the male provides the female with food and assistance until the young can fend for itself, normally four months which remains with them until the next breeding season.
Food:
It feeds almost exclusively on the seeds several species of She-oak (Casuarina and Allocasuarina). You can also sometimes eat larvae of wood-boring. They feed in threes, less frequently in pairs, small groups or flocks of up to 60 birds. They can be detected by the snapping of their beaks and the remains of the casuarina cones and twigs that fall.
Distribution:
Size distribution (reproduction / resident): 770.000 km2
The species is Rare Although widespread in suitable forests of the central coast and forest habitats of Queensland and in the interior of the southern plateaus and Plains of the Midwest's New South Wales, with a small population in the Riverina. There is an isolated population in the Kangaroo Island, South of Australia.

Like most parrot species, the Glossy black cockatoo is protected by the Convention on international trade in endangered species of Fauna and Flora Silvestres ( CITES ), with its inclusion in the list of the Appendix II of vulnerable species, What makes the import, the export and trade of animals captured in the wild is illegal.
Justification of the population
Garnett and Crowley (2000) estimated the size of the population in the following way: 12.000 individuals of the subspecies lathami, 70 breeding pairs of the subspecies halmaturinus (equivalent to 140 individuals) and 5.000 individuals of the subspecies erebus giving a total of 17.140 individuals.
Justification of trend
They suspected that the population is declining in general Since the largest subpopulation, lathami, It is slowly decreasing throughout its range. However it is believed that the subspecies Erebus is increasing and the subspecies halmaturinus It is increasing as a result of conservation efforts in the Island Ganguro (Garnett and Crowley 2000).
"Glossy black cockatoo" in captivity:
