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.

Possible
About 20% of wildlife watchers report a Red-tailed Black-Cockatoo sighting in Perth on a given day, based on 2,358 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 162 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Red-tailed Black-Cockatoo in Perth on a given day, against about 20% in April–July and September–December, the lowest months. That is one of Perth's driest months, with about 15 mm of rain against 130 mm in July.
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.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Red-tailed Black-Cockatoo sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Psittacidae
The closest relatives of the Red-tailed Black-Cockatoo that you can see in Perth (family Psittacidae, New World and African Parrots) are Coconut Lorikeet (about 80%), Galah (about 50%) and Little Corella (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 Perth (2,358 verified sightings), 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.
