Glossy Black-Cockatoo Facts


Did you know?

Glossy Black-Cockatoo, Calyptorhynchus lathami, are one of the more threatened species of cockatoo in Australia and are listed as vulnerable under QLD and NSW legislation.

There are 3 subspecies recognised across their distribution range with two of these occurring in QLD (see table).

Sub Species
Not listed


C.lathami lathami is located in the South-Eastern corner of Queensland, Eastern and Northern New South Wales, extending slightly into Victoria with populations known in South Australia and Kangaroo Island. South East Queensland and Northern NSW is a stronghold for the species.

Feeding and Breeding

Glossy Black-Cockatoo have a very restricted diet, feeding only on the seeds in cones of she-oaks (Casuarina and Allocasuarina) and only on selected individual trees.

They are one of the friendliest birds and are not easily disturbed when feeding

They will sit quietly and the only noise you will hear is the soft sound of cracking cones, people often do not even realise they are there.

In South-east Queensland Glossy Black-Cockatoos' favoured food trees are the black she-oak (Allocasuarina littoralis) and forest she-oak (Allocasuarina torulosa). In the SEQ and northern NSW regions they have also been known to feed on C. cristata and C.equisetifolia.

They will return to the same food tree time and time again, often ignoring nearby trees that are full of cones, but these patterns of feeding are poorly understood.

They can fly more than 10km to feeding areas.

Breeding occurs every two years with a single egg being laid in late January to early June with a longer nestling period then any other cockatoos (up to 90 days). The young are dependent on the parents for at least 12 months.

Large hollow bearing trees are needed for breeding, emphazising the need to retain remnant vegetation in these areas just as much as food trees. Glossy Black-Cockatoo are known to have a life span that can exceed 30 years.

Some of the most important information is being able to correctly identify the species (as well as the sex and age of individuals) as well as their feeding trees. Recognising their characteristic feeding evidence is also useful to identify important habitats. Happy reading!
