One notable Eleonora cockatoo is Snowball, a bird recently demonstrated to be capable of beat induction – in other words, that the bird is capable of perceiving a musical beat and dancing to it. Both parents incubate the eggs and in turn provide for the chicks. The female lays 2–3 white oval eggs, which hatch after a period of 30 days. ![]() The birds build their nests in a tree hollow or rock crevice. The breeding season of this cockatoo is mainly from September to January. It feeds on nuts, berries, flower buds, flowers, seeds and insects. In the wild, the Eleonora cockatoo is found in open woodlands, forests, and semi-arid forested areas, as well as partially cleared forest areas. The Eleonora also has a bald patch behind its crest. ![]() The Eleonora cockatoo often has pale yellow ear patches, and yellow diffusion throughout the body, especially under the wings and tail. Although a smaller and lighter bird, in practice it may be difficult to differentiate this subspecies from the Triton cockatoo. Apart from the size difference, the Eleonora differs from the greater sulphur crested in that it doesn't have as prominent white eyerings (they often are a pale blue), the crest of an Eleonora is often less curved and it doesn't have the pointy upper mandible, which is only found in Cacatua galerita galerita. It is the smallest of the four subspecies of Cacatua galerita, at approx. Characteristics Head and upper body detail This subspecies was accepted by Gerlof Mees in 1972 and Joseph Forshaw (1989) and recognised by Edward C. He discovered the subspecies in Amsterdam's Artis zoo and named it after Maria Eleonora van der Schroef, the wife of the then director of the zoo. ![]() The Eleonora cockatoo was named by Otto Finsch. Avicultural populations are well-established in Europe and the United States. It is native to the Aru Islands in the province of Maluku in eastern Indonesia, but has also been introduced to Kai Islands. The Eleonora cockatoo, Cacatua galerita eleonora, also known as medium sulphur-crested cockatoo, is a subspecies of the sulphur-crested cockatoo. ![]()
