There are three subspecies of Red-tailed Black Cockatoo in Western Australia. It has declined due to destruction of forests and woodlands, also competition for nest hollows with native and exotic species and the impact of fire. Usually seen in pairs or small flocks, seldom large flocks (up to 200). It was formerly common, but is now rare to uncommon and patchily distributed over a range which has become markedly reduced. “Vulnerable: under Federal Environmental Protection and Biodiversity Conservation Act”. “Listed Vulnerable: Schedule 1 – Western Australian Wildlife Conservation Act”.
The south-western population naso (referring to its large bill) was named by John Gould in 1837. Pair of Forest Red-tailed Black Cockatoosĭownload Forest Red-tailed Black Cockatoo factsheet Other Names Forest Red-tailed Black Cockatoo Forest Red-tailed Black Cockatoo
