Physical description Click here for a physical description Red-tailed Black-Cockatoos are noisy, large Black-Cockatoos that usually live in flocks. Their plumage is dimorphic, i.e. males and females are slightly different. Male Red-tailed Black-Cockatoos have glossy black plumage, with a big crest. Females are spotted (head, wings) or barred (front) yellow. While males have solid red undertail panels, those of females are barred, with a colour gradient from orange to red. Males have dark-grey bills, females light-grey ones. The irises of both sexes are dark, the legs and feet grey. Juveniles resemble female Red-tailed Black-Cockatoos, with a darker head. Twitcher's tip Compared with Glossy Black-Cockatoos, Red-tailed Black-Cockatoos have a much more pronounced crest and larger red tail panels.

Taxonomy, classification See Red-tailed Black Cockatoo at Wikipedia .

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 Red-tailed Black-Cockatoo is available HERE . Red-tailed Black-Cockatoos are endemic to the Australian continent. There are five races - for details see a field guide. Nominate race "banksii" is found basically only in QLD, except the south-western corner of the state (the Lake Eyre Basin). Along the tropical North of Australia, from the southern tip of the Gulf of Carpentaria in the East to about the Kimberley in the West, and across the northern half of the NT, race "macrorhynchus" is found. In the western half of WA (except a narrow coastal strip and the south-western corner) race "samueli" is present. This inland race also inhabits the arid centre, in the border regions between the NT, SA and QLD, and also along parts of the Darling River (notably in Walgett, NSW) and some of its tributaries. Race "naso" is found only in the south-western corner of WA and race "graptogyne" in the coastal region near the SA/VIC border. Red-tailed Black-Cockatoos can be found in various types of forest, from open to dense, often with cypress and/or black pine. In the interior of the continent, they are often found in River Red Gums along rivers and creeks. They also go into areas with human activity (farms, parks) to feed on other seeds, such as e.g. those of the White Cedar tree. Where to look? How to find this species? Red-tailed Black-Cockatoos are most easily found near major inland watercourses, e.g. along the Darling River. There they will often be perched in River Red Gums. In general, when not feeding they will usually be perched high up in the crowns of tall trees. In townships they can be found feeding on seeds, e.g. of White Cedar trees. At sunset they can often also be found drinking water from rivers, creeks or dams.

Sightings Click here for sighting information Race "banksii" Red-tailed Black-Cockatoos, nominate race "banksii", were spotted by L. Tonnochy 20 km West of Townsville, QLD, in May 2012. M. Mearns reports spotting Red-tailed Black-Cockatoos, nominate race "banksii", near Croydon, QLD, in July 2016 and again in September 2019, and at Cobbold Gorge, QLD, in July 2016. A. Campbell reports finding Red-tailed Black-Cockatoos, nominate race "banksii", at Mount McEuen, QLD, in December 2016. M. Eaton reports spotting Red-tailed Black-Cockatoos, nominate race "banksii", at Bunya Mountains NP, QLD, in March 2018. They were also found in Windorah, QLD, in August 2022. A. Ross-Taylor found Red-tailed Black-Cockatoos, nominate race "banksii", at Taylors Beach, near Ingham, QLD, in November 2021, and on the Atherton Tablelands, QLD, in May 2022. Race "macrorhynchus" Red-tailed Black-Cockatoos, race "macrorhynchus", were observed by S. Kirkby in the NT, about 100 km South of Darwin, NT, in June 2011. B. Hensen reports spotting race "macrorhynchus" in Darwin, NT, in July 2013. We have found them in the Darwin area again in August 2014. J. Greaves reports spotting Red-tailed Black-Cockatoos, race "macrorhynchus", at Yellow Water, Kakadu NP, NT, in November 2014. P. Brown found Red-tailed Black-Cockatoos, race "macrorhynchus", along the Marrakai track, Top End, NT, in August 2018, and along the Bird Billabong, Adelaide River, Mary River NP, Top End, NT, in November 2019. M. Eaton reports finding Red-tailed Black-Cockatoos, race "macrorhynchus", in Keep River NP, NT, in July 2020. Race "samueli" Red-tailed Black-Cockatoos, race "samueli", were first spotted by us on a trip to western NSW in March 2008. There were tens of birds along the banks of the Darling River in the township of Bourke, NSW, plus many more farther South-West, following the Darling River. In October 2010 there were at least 100 Red-tailed Black-Cockatoos, race "samueli", in the township of Walgett, western NSW, feasting on the previous year's White Cedar fruit. Small flocks of Red-tailed Black-Cockatoos, race "samueli", were again present in Brewarrina and Walgett, NSW, feeding in flowering White Cedar trees in September 2012. They are found along the Barwon/Darling River system regularly. J. Greaves reports spotting Red-tailed Black-Cockatoos, race "samueli", at Merredin, WA, in February 2015. Race "naso" J. Greaves reports spotting Red-tailed Black-Cockatoos, race "naso", at Mundaring, 35 km East of Perth, WA, in December 2014, and in Bungendore Park, SE of Perth, in June 2015. M. Eaton found a Red-tailed Black-Cockatoo, race "naso", in Perth, WA, in April 2019. C. Pears reports finding Red-tailed Black-Cockatoos, race "naso", in Swanbourne and at Lake Claremont, Perth, WA, in April 2021. They were also found at Mellenbye Station, ca. 50 km NE of Morawa, WA, in September 2022. 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 to be Red-tailed Black-Cockatoos.
