There were no records in the first national bird atlas, and a record(s) in only one extreme north-eastern one-degree grid, at the lowest reporting rate, in the second national atlas (Blakers et al. The other two are probably correct, because one (at Wilsons Creek north of Alstonville) was made by a knowledgeable observer, and the other at Cabarita on the Tweed coast described feeding on a known food source (Horsetail She-oak) of the Red-tailed Black-Cockatoo which has not been recorded for the Glossy Black-Cockatoo. Of the four valid or probably valid records of the coastal Red-tailed Black-Cockatoo since 1980, only one sighting, at Bungawalbin Nature Reserve, was supported by an expert identification eliminating the Glossy Black-Cockatoo, and one other, at Round Mountain (Bogangar), was an expert identification by a CSIRO biologist during the State Forests Murwillumbah District environmental assessment. Since that time there have been very occasional sightings in extreme north-east NSW, around the Tweed and lower Richmond Valleys (NSW Wildlife Atlas). The Red-tailed Black-Cockatoo (coastal subspecies) Calyptorhynchus banksii banksii has been confirmed as historically occurring in NSW south to Sydney (McAllan 2002), but it rapidly contracted to the far North Coast (Bellinger and Macleay River valleys), and was last seen regularly on the Tweed River in the 1970s (Higgins 1999). The Red-tailed Black-Cockatoo is distributed throughout much of Australia, but its southern and inland populations are fragmented into isolates that constitute separate subspecies (Higgins 1999). The Yellow-tailed Black-Cockatoo has a yellow ear patch and tail panel, and loud wailing calls.Ģ. It is very similar to the smaller Glossy Black-Cockatoo, which has a small crest, softer and less discordant calls, and females have a grey bill and large yellow blotches on the head. The Red-tailed Black-Cockatoo is a large (60 cm) black cockatoo with a bushy crest and a red tail panel the female has a white bill, fine yellow spots and bars on the head and body, and an orange tail panel with fine black bars. ![]() NSW Scientific Committee - final determinationġ. Listing of Critically Endangered species is provided for by Part 2 of the Act. The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the Red-tailed Black-Cockatoo (coastal subspecies) Calyptorhynchus banksii banksii (Latham, 1790) as a CRITICALLY ENDANGERED SPECIES in Part 1 of Schedule 1A of the Act, and as a consequence, to omit reference to Calyptorhynchus banksii (Latham, 1790) from Part 1 of Schedule 2 (Vulnerable species) of the Act.
