Genus: Callocephalon | Species: fimbriatum The Gang-gang Cockatoo ( Callocephalon fimbriatum ) stays without any further changes.Related publications: Callocephalon fimbriatum Within three following generations, their population should have a half size. According to the prediction of ornithologists from Perth, both cockatoo species are under a serious threat of loosing their original habitats, nesting opportunities and food sources. In the case of the the Short-billed Black Cockatoo, the estimates are more promising – about 40 thousands. The BirdLife International estimates the size of population of the Long-billed Black Cockatoo on 1000 to 1500 individuals. Soon after the new taxonomy arised, both white-tailed cockatoos were classified in the IUCN Red List as „endangered“ (EN). That’s one of the several causes why they were separated. Both white-tailed black cockatoos are far more rare then the yello-tailed. The Long-billed Black Cockatoo live occurs in inland of southwestern Australia while the Short-billed Black Cockatoo lives on the coast in the same area. As the name say, the first cockatoo species has a longer beak than the second. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable. Another distinct characteristic is the length of the beak. Cockatoos are monogamous and nest in tree hollows. The Yellow-tailed Black Cockatoo ( Zanda funerea ) has the yellow ear marking while the Long-billed Black Cockatoo ( Zanda baudinii ) and the Short-billed Black Cockatoo ( Zanda latirostris ) the white instead. ![]() White-tailed Black Cockatoo and Yellow-tailed Black Cockatoo represent a new taxon ZandaĪll three species look alike. All subspecies of the Glossy Black Cockatoo stay without any change – Calyptorhynchus lathami lathami, Calyptorhynchus lathami erebus and Calyptorhynchus lathami halmaturiunus. They are Calyptorhynchus banksii banksii, Calyptorhynchus banksii naso, Calyptorhynchus banksii macrorhynchus, Calyptorhynchus banksii samueli, and Calyptorhynchus banksii graptogyne. The Red-tailed Black cockatoo has five subspecies now, not four as it used to be. However, the last three species have been replaced to the new genus Zanda. The first two cockatoo species stay in the same taxon. The second genus of black cockatoos containted five separated cockatoo species up to the last year – the Red-tailed Cockatoo ( Calyptorhynchus banksii ), Yellow-tailed Black cockatoo ( Calyptorhynchus funereus ), Long-billed Black Cockatoo ( Calyptorhynchus baudinii ) and Short-billed Black Cockatoo ( Calyptorhynchus latirostris ). Only the new subspecies occurs in Australia, the rest we will find on New Guinea and surrounding islands. Two old subspecies Probosciger aterrimus goliath and Probosciger aterrimus stenolophus stay without any change.
