WLicmetis is a subgenus of the white cockatoos. They are collectively known as corellas in Australia. Three of the six species are primarily – or only – found in Australia, while the Philippines, Indonesia, and the Solomons each have an endemic species. They are relatively small cockatoos and – unlike the members of the subgenus Cacatua – all have pale bills. While most show yellow-tinged underwings and some red to the face, none has conspicuously coloured crests.
WMuir's corella is a stocky, medium-sized white cockatoo endemic to Western Australia. It was the threatened nominate subspecies of the western corella. It was removed from the WA's threatened species list in November 2012 as a result of successful conservation efforts.
WThe little corella, also known as the short-billed corella, bare-eyed cockatoo, blood-stained cockatoo, and little cockatoo is a white cockatoo native to Australia and southern New Guinea. It was known as Birdirra among the Yindjibarndi people of the central and western Pilbara. They would keep them as pets, or traditionally cook and eat them. The downy feathers are used in traditional ceremonies and dances where they adorn head and armbands.
WThe long-billed corella or slender-billed corella is a cockatoo native to Australia, which is similar in appearance to the little corella. This species is mostly white, with a reddish-pink face and forehead, and has a long, pale beak, which is used to dig for roots and seeds. It has reddish-pink feathers on the breast and belly.
WThe red-vented cockatoo, also known as the Philippine cockatoo and locally katala, abukay, agay or kalangay, is a critically endangered species of cockatoo that is endemic to the Philippines. It is roughly the size and shape of the Tanimbar corella, but is easily distinguished by the red feathers around the vent. It is threatened by habitat loss and the cage-bird trade.
WThe Solomons cockatoo, also known as the Ducorps's cockatoo, Solomons corella or broad-crested corella, is a species of cockatoo endemic to the Solomon Islands archipelago. This small white cockatoo is larger than the Tanimbar corella yet smaller than the umbrella cockatoo. The species is common across most of the Solomons, absent only from Makira in the south. It inhabits lowland rainforests, secondary forests, cleared areas and gardens.
WThe Tanimbar corella, also known as Goffin's cockatoo, is a species of cockatoo endemic to forests of Yamdena, Larat and Selaru, all islands in the Tanimbar Islands archipelago in Indonesia. It has been introduced to the Kai Islands, Indonesia, Puerto Rico and Singapore. This species was only formally described in 2004, after it was discovered that the previous formal descriptions pertained to individuals of a different cockatoo species, the Ducorps' or Solomons cockatoo. Tanimbar corellas are the smallest of the white cockatoos. It is classified as Near Threatened due to deforestation and bird trade. It breeds well in captivity and there is a large avicultural population.
WThe western corella also known as the western long-billed corella, is a species of white cockatoo endemic to south-western Australia.
