The red-tailed black cockatoo (Calyptorhynchus banksii) also known as Banksian- or Banks' black cockatoo, is a large black cockatoo native to Australia. Adult males have a characteristic pair of bright red panels on the tail that gives the species its name. It is more common in the drier parts of the continent. Five subspecies are recognised, differing chiefly in beak size. Although the more northerly subspecies are widespread, the two southern subspecies, the forest red-tailed black cockatoo and the south-eastern red-tailed black cockatoo are under threat.
The species is usually found in eucalyptus woodlands, or along water courses. In the more northerly parts of the country, these cockatoos are commonly seen in large flocks. They are seed eaters and cavity nesters, and as such depend on trees with fairly large diameters, generally Eucalyptus. Populations in southeastern Australia are threatened by deforestation and other habitat alterations. Of the black cockatoos, the red-tailed is the most adaptable to aviculture, although black cockatoos are much rarer and much more expensive in aviculture outside Australia.

Likely
About 50% of wildlife watchers report a Red-tailed Black-Cockatoo sighting in Nitmiluk National Park on a given day, based on 265 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 70% of wildlife watchers report a Red-tailed Black-Cockatoo in Nitmiluk National Park on a given day, against about 40% in January, March, July and November, the lowest months. That is one of Nitmiluk National Park's driest months, with about 25 mm of rain against 270 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Red-tailed Black-Cockatoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Red-tailed Black-Cockatoo sightings, Nitmiluk National Park has the highest daily chance: about 50%. Next come Kakadu National Park (Australia, about 50%) and Litchfield National Park (Australia, about 40%).
Same family: Psittacidae
The closest relatives of the Red-tailed Black-Cockatoo that you can see in Nitmiluk National Park (family Psittacidae, New World and African Parrots) are Red-collared Lorikeet (about 80%), Sulphur-crested Cockatoo (about 60%) and Galah (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-tailed Black-Cockatoo is recorded against all the birds logged in Nitmiluk National Park (265 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
