Physical description Click here for a physical description Glossy Black-Cockatoos, although not much smaller than other species of Black-Cockatoos, are the smallest Black-Cockatoos in Australia. Their plumage is dimorphic, i.e. males and females are slightly different. While the body of both sexes is near-black dark-brown, the head of males is all dark-brown, whereas the head of females is brown with irregular yellow blotches. The head plumage of both sexes can show quite some colour variation. Adults have two solid-red panels on their undertail. Bill, legs and feet are grey, the irises are dark. Juvenile Glossy Black-Cockatoos have plumage similar to adult males, but with small silvery specks, while their tail panels are barred red. Twitcher's tip Compared with Red-tailed Black-Cockatoos, Glossy Black-Cockatoos have a much less pronounced crest and have smaller red tail panels. Apart from juveniles, they are also much less speckled.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Glossy Black-Cockatoo is available HERE . Glossy Black-Cockatoos are endemic to the Australian continent. There are three races of Glossy Black-Cockatoos. Nominate race "lathami" is found along the coastal strip from about the NSW/VIC border in the South to the south-eastern corner of QLD. They also live in the hills of the Great Dividing Range behind these coastal areas, into parts of the Murray-Darling Basin. In a roughly triangular area in QLD, with Bundaberg, Moranbah and Roma as its corners, with a coastal extension to Townsville, race "erebus" is found. Race "halmaturinus" populates Kangaroo Island. Note that, despite the fact that in the 21st century there are, with the exception of the far north-eastern corner at the border with NSW, no Glossy Black-Cockatoos in VIC, the existence of race "halmaturinus" on Kangaroo Island suggests that the species was once found all through VIC. This is also reflected in the fact that a western Victorian Aboriginal language has a name for the species that translates into "eater of she-oak cones". Glossy Black-Cockatoos can be found in various types of forest, often open, sometimes also denser. They have a strong preference for the seeds of Casuarina trees and are therefore often found around such trees, especially if they have mature cones. Where to look? How to find this species? Glossy Black-Cockatoos are found most easily at dams or waterholes around sunset in forests and woodland with significant numbers of casuarinas.

Sightings Click here for sighting information Race "lathami" Glossy Black-Cockatoos, race "lathami", were first found by us in Jack's Creek State Forest (20 km South of Narrabri) in 2003, other parts of the Pilliga scrub and also about 20-30 km West of Narrabri. Glossy Black-Cockatoos, race "lathami", are found in various places around Narrabri, NSW, especially in areas with casuarinas. Although sighted regularly by us in these areas in the years 2003-2006, in general Glossy Black-Cockatoos are quite rare. They live in small groups; typical sightings are of two or three individuals, sometimes small groups of up to six birds. In the Pilliga NR, South of Narrabri, flocks of up to tens (probably consisting of subgroups that will disperse again at some point) have been spotted at various dams. C. Pears reports finding Glossy Black-Cockatoos, race "lathami", in Katoomba, NSW, in March 2010. Glossy Black-Cockatoos, race "lathami", are also infrequently seen by us in the foothills of the Nandewar Range, e.g. at Eulah Creek, where they can sometimes be seen flying over. In the timeframe December 2014 to March 2015, when it was particularly dry in one of their strongholds, the Pilliga scrub, and when bushfires had destroyed part of the native vegetation, increased numbers were seen by us flying over Eulah Creek towards the hills and large contiguous forests of the Great Dividing Range. In the timeframe December 2017 to January 2018 we have also seen them twice at Yarrie Lake, on the northern edge of the Pilliga scrub. C. Hayne reports that Glossy Black-Cockatoos, race "lathami", are occasionally seen in the area of Moree, NSW. In April 2014 a pair of Glossy Black-Cockatoos was spotted in the Gwydir Wetlands, about 70 km North-West of Moree, NSW. A. Ross-Taylor reports spotting Glossy Black-Cockatoos, race "lathami", at Nerang NP, Gold Coast, QLD, in October 2013. A group of 7 Glossy Black-Cockatoos, race "lathami", was spotted by us in the Goonoo NP, between Dubbo and Mendooran, NSW, in October 2015. M. Windeyer reports that Glossy Black-Cockatoos, race "lathami", are regularly found in the Gilgandra Flora Reserve, near Gilgandra, NSW. M. Eaton reports finding Glossy Black-Cockatoos, race "lathami", at O'Reilly's Plateau, Lamington NP, Gold Coast, QLD, in January 2020. Another pair was found at Port Macquarie, NSW, in January 2021. Race "erebus" In July 2009 Glossy Black-Cockatoos, race "erebus", were seen by us in two locations in QLD, namely at Mt. Archer NP, eastward of Rockhampton, QLD, and on the eastern outskirts of Kroombit Tops NP, QLD. C. Linfoot reports finding a juvenile Glossy Black-Cockatoo, race "erebus", at Hervey Range, near Townsville, QLD, in September 2022. This location is near the northern end of the species'/race's range. Race "halmaturinus" J. Greaves reports spotting a small family clan of Glossy Black-Cockatoos, race "halmaturinus", at Lathami Conservation Park, Kangaroo Island, SA, in March 2016. Twitcher's tip If you see black cockatoos with red tail markings in a group of only a few, it is likely that you are looking at Glossy Black-Cockatoos. If they come in a big flock, they are likely Red-tailed Black-Cockatoos.

Behaviour

Social behaviour: Communal

Mobility: Sedentary/dispersive

Elementary unit: Pair/family clan

When courting a female, the male Glossy Black-Cockatoo intonates a monotonous song reminiscent (to humans) of a car alarm. Upon the last intonation of the refrain, which increases in volume, the male bows and displays his crest and the red patches on the underside of its tail to the female (see photo). After a few seconds, and possibly after a move to a more advantageous point, the whole routine starts all over.

Similar to other cockatoo species, Glossy Black-Cockatoos also show playful behaviour, like the male bird in the photo below.

Food, Diet

Adults: Casuarina seeds

Dependents: Regurgitated seeds

Water intake: Daily

Like basically all cockatoos, Glossy Black-Cockatoos are seed-eaters. They have a strong preference for the cones of casuarinas ("She-oaks").

[Nerang NP, QLD, October 2013]

Contrary to other birds eating cones of conifers, Glossy Black-Cockatoos do not crack casuarina ("She-oak") cones to extract the seeds, but instead eat the whole lot. Below a close look at such a cone, which is about 10 mm long.
