![]() This biological relation to other cockatoos is further supported by the existence of at least one documented case of a successful hybrid between a cockatiel and a galah, another cockatoo species. The cockatiel is now biologically classified as a genuine member of Cacatuidae on account of sharing all of the cockatoo family's biological features, namely, the erectile crest, a gallbladder, powder down, suppressed cloudy-layer (which precludes the display of blue and green structural colours), and facial feathers covering the sides of the beak, all of which are rarely found outside the family Cacatuidae. Cockatiels are native to Australia, favouring the Australian wetlands, scrublands, and bushlands. It is, therefore, now classified as the smallest of the Cacatuidae (cockatoo family). It was previously considered a crested parrot or small cockatoo however, more recent molecular studies have assigned it to its own subfamily, Nymphicinae. The cockatiel is the only member of the genus Nymphicus. As a caged bird, cockatiels are second in popularity only to the budgerigar. They are prized as household pets and companion parrots throughout the world and are relatively easy to breed. “There’s already been two sightings in the last six months of juvenile males, which are possibly scouting potential sites for feeding, and they’ve both been luckily close to areas where we’re rolling out the project.The cockatiel (Nymphicus hollandicus), also known as weiro bird, or quarrion, is a bird that is a member of its own branch of the cockatoo family endemic to Australia. The new habitats would be an “insurance policy” for the population, Woodroffe said. Then they find landholders happy for them to use large swathes of their land to plant trees. They have been collecting seeds from different temperature and rainfall zones to buffer against “whatever climate change brings”. Woodroffe said they picked sites based on proximity to the island and the needs and preferences of glossies. The different sites should help the glossies chance on a new habitat if they make the 14km flight from Kangaroo Island. If the plan succeeds, there will be a dense cover of sheoaks within five years. They will plant 19,000 trees across three sites – drooping sheoaks for food and eucalypts such as river red gum and pink gum for nesting hollows. “Greening Australia and WWF are rebuilding quality habitat and we’re really excited that this could potentially bring glossy black cockatoos back to the mainland,” he said. The WWF Australia forests program manager, Ben Sanders, said only about 2% of the original 22,000 hectares of sheoak woodland remains on the Fleurieu. But against all expectations, in 2020 there were 454 birds. In 2019, bushfires destroyed more than half of the sheoak feeding habitat and almost four in 10 nesting spots. The population slowly built up to more than 350 by 2016. In the 1970s much of the glossies’ SA habitat was cleared for development.īy 1995, when recovery efforts began, there were just 158 birds left. They feed almost exclusively on the seeds of the drooping sheoak and nest in hollows in eucalyptus trees. ![]() ![]() The SA subspecies is smaller than those on the east coast, has a more bulbous bill and is endangered whereas the others are listed as vulnerable. They are vulnerable to habitat destruction through development and flooding, the possums that eat their eggs and young chicks, and threats from galahs, little corellas, sulphur-crested cockatoos and feral honeybees. Young birds have yellow spots on their heads, breasts, bellies and flanks.īird pairs mate for life and raise just one fledgling a year. ![]() The males have red or orange stripes on their tails and the adult females have yellow patches on their heads. Glossy black cockatoos are the smallest of Australia’s black cockatoo species.

Now, Greening Australia and the WWF Australia are planting almost 20,000 trees in the hope of tempting the birds across Backstairs Passage to the Fleurieu Peninsula. Glossy Black-Cockatoos are less gregarious and quieter than their Yellow-tailed or Red-tailed relatives and generally travel in small groups of two or three. For now, the SA subspecies of “glossies” exists only on Kangaroo Island, where it rose from the ashes of the 2019-20 bushfires that destroyed much of its habitat. ![]()
