Red-tailed Black Cockatoo

Calyptorhynchus banksii

The red-tailed black cockatoo 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. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 29°C (typically 20 to 32°C, from 6 areas). That range is wide, so temperature alone does not explain when it turns up.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
