(according to the fossil record) or 66 m.y.a. While psittaciform parrots (true parrots) and cockatoos have many common anatomical attributes such as zygodactyl feet and hooked bills, the cockatoos and true parrots diverged from the ancestral parrots as separate lineages as early as 45 m.y.a. The term "white cockatoo" has also been applied as a group term to members of the subgenus Cacatua, the genus Cacatua as well as larger groups including Major Mitchell's cockatoo and the galah cockatoo. It lies in the subgenus Cacatua within the genus Cacatua.
Its species name alba is a feminine form of the Latin adjective albus for "white". The white cockatoo was first described in 1776 by German zoologist Philipp Ludwig Statius Müller. The white cockatoo is known as ayab (plural form: ayot) in the Burmeso language of Papua, Indonesia.
It is similar to other species of white cockatoo such as yellow-crested cockatoo, sulphur-crested cockatoo, and salmon-crested cockatoo, all of which have yellow, orange or pink crest feathers instead of white. The wings and tail have a pale yellow or lemon color which is exposed when they fly. When surprised, it extends a large and striking head crest, which has a semicircular shape (similar to an umbrella, hence the alternative name).

Its presence not only confirms the interests and purchasing power of Mantegna and his patrons, the Gonzagas, it reveals the complexity and range of South-East Asian trading networks prior to the establishment of European trading posts in the region. The Sulphur-crested Cockatoo in the Madonna della Vittoria provides a unique opportunity to place fifteenth-century Italy in its global context. I also explore the intriguing issue of how a creature native to regions generally considered to have been beyond Europe's trading reach in 1496 could have appeared in a Renaissance artwork. In this article, I consider why Mantegna would have included parrots in his altarpiece and the symbolic significance of the cockatoo's position in the composition. Although Mantegna's altarpiece has been the subject of attention in modern scholarship, the significance of the Sulphur-crested Cockatoo has not been explored. This article focuses on that image – a small but significant detail in Andrea Mantegna's Madonna della Vittoria, completed in Mantua in 1496. The earliest image of an Australasian parrot by a European artist predates the arrival of Vasco de Gama's fleet at Calicut on the Malabar Coast in 1498.
