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. Until 2023, the citron-crested cockatoo ( Cacatua citrinocristata) was considered by the IOC to be a subspecies of yellow-crested cockatoo. 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. parvula (Timor yellow-crested cockatoo) ( Bonaparte, 1850) – Sumbawa, Komodo, Flores, Timor, and various other islands in the Lesser Sundas

abbotti (Abbott's yellow-crested cockatoo) ( Oberholser, 1917) – Masalembu Islands sulphurea ( nominate subspecies) ( Gmelin, JF, 1788) – Sulawesi and nearby smaller islands A yellow-crested cockatoo (left) and a sulphur-crested cockatoo in a Hong Kong parkĪccording to the International Ornithological Congress, 5 subspecies are recognized: The yellow-crested cockatoo in now one of 11 species placed in the genus Cacatua that was introduced in 1817 by Louis Jean Pierre Vieillot. 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 were 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 used to be considered 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.
