Several national parks provide protection of their habitat, including Rawa Aopa Watumohai National Park on Sulawesi, Komodo National Park on Komodo Island, the national parks of Manupeu Tanah Daru and Laiwangi Wanggameti on Sumba, and the Nino Konis Santana National Park in East Timor (Timor-Leste). The decline results from trapping and logging, especially of mangrove ( Avicennia apiculata) and kapok trees. Its population on this tiny island (about 5 km 2 or 1.9 mi 2) had fallen to 10 as of June and July 2008. abbotti is found only on the island of Masakambing. The current population is estimated at fewer than 2,500 individuals and is thought to be declining in number. Between 19, over 100,000 of these birds were legally exported from Indonesia, yet a German proposal submitted to CITES to move it to Appendix I was not approved. Numbers have declined dramatically due to illegal trapping for the cage-bird trade. The yellow-crested cockatoo is critically endangered. Status and conservation Ī legally owned family pet from the United Kingdom The eggs are incubated for about 28 days and the chicks leave the nest about 75 days after hatching. The incubation is shared by both parents. The eggs are white and usually two in a clutch. The yellow-crested cockatoo nests in tree cavities. The subspecies paulandrewi, thought to be endemic to the Tukangbesi Islands and also recognized in the 2014 study, is not recognized by the IOC. Previously, only 4 of these were recognized, but djampeana and occidentalis were recognized in 2022 based on a 2014 phylogenetic study. citrinocristata ( citron-crested cockatoo) ( Fraser, 1844) – Sumba parvula (Timor yellow-crested cockatoo) ( Bonaparte, 1850) – Sumbawa, Komodo, Flores, Timor, and various other islands in the Lesser Sundas

The type locality is the island of Sulawesi, Indonesia. He placed it with the parrots in the genus Psittacus and coined the binomial name Psittacus sulphureus. When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1788 he included the yellow-crested cockatoo based on the accounts by earlier naturalists. Then in 1764 George Edwards included the "Lesser white cockatoo with a yellow crest" in his Gleanings of natural history from a pet bird kept at a home in Essex, and in 1779 French polymath Comte de Buffon included the bird in his Histoire Naturelle des Oiseaux. In 1760 the French zoologist Mathurin Jacques Brisson included "Le Kakatoes à hupe jaune" in his Onithologie based on a live bird that he had seen in Paris. In 1738 English naturalist Eleazar Albin included a description and illustration of the "Cockatoo or White crested parrot" in his A Natural History of Birds based on a bird displayed at "The Tiger" tavern on Tower Hill in London. In the 18th century yellow-crested cockatoos was imported into Europe as pets and these birds were described by various naturalists. The yellow-crested cockatoo's diet consists mainly of seeds, buds, fruits, nuts, and herbaceous plants. The citron-crested cockatoo, which is a subspecies of the yellow-crested cockatoo, is similar, but its crest is clearly orange. Also, the yellow-crested cockatoo's crest is a brighter color, closer to orange. It is easily confused with the larger and more common sulphur-crested cockatoo, which has a more easterly distribution and can be distinguished by the lack of pale yellow coloring on its cheeks (although some sulphur-cresteds develop yellowish patches). The yellow-crested cockatoo is found in wooded and cultivated areas of East Timor and Indonesia's islands of Sulawesi and the Lesser Sundas. The yellow-crested cockatoo ( Cacatua sulphurea) also known as the lesser sulphur-crested cockatoo, is a medium-sized (about 34-cm-long) cockatoo with white plumage, bluish-white bare orbital skin, grey feet, a black bill, and a retractile yellow or orange crest.
