The Major Mitchell's Cockatoo, Lophochroa leadbeateri, also known as Leadbeater's Cockatoo or Pink Cockatoo, is a medium-sized cockatoo restricted to arid and semi-arid inland areas of Australia. It is here placed in its own monotypic genus Lophochroa, though to include it in Cacatua as others do is not wrong as long as the corellas are also included there.[1][2]

Description

Adult perched on a tree in Melbourne Zoo

With its soft-textured white and salmon-pink plumage and large, bright red and yellow crest, it is generally recognised as the most beautiful of all cockatoos. It is named in honour of Major Sir Thomas Mitchell, who wrote "Few birds more enliven the monotonous hues of the Australian forest than this beautiful species whose pink-coloured wings and flowing crest might have embellished the air of a more voluptuous region".

Systematics and naming

It is possibly (though not certainly) a little closer related to Cacatua than the Galah, and its lineage diverged around the time of or shortly after the acquisition of the long crest – probably the former as this crest type is not found in all Cacatua cockatoos and therefore must have been present in an early or incipient stage at the time of the divergence of the Major Mitchell's Cockatoo's ancestors. Like the Galah, this species has not lost the ability to deposit diluted pigments dyes in its body plumage, although it does not produce melanin coloration anymore, resulting in a lighter bird overall compared to the Galah. Indeed, disregarding the crest, Major Mitchell's Cockatoo looks almost like a near-leucistic version of that species (see also "External links" below). Another indication of the early divergence of this species from the "white" cockatoo lineage is the presence of features found otherwise only in corellas, such as the plaintive yodeling cry, as well as others which are unique to Major Mitchell's and the true white cockatoos, for example the large crest and rounded wing shape.[1]

The scientific name commemorates the British naturalist, Benjamin Leadbeater. In Central Australia south of Alice Springs, the Pitjantjatjara term is kakalyalya.[3]

Distribution and habitat

Unlike the Galah, Major Mitchell's Cockatoo has declined rather than increased as a result of man-made changes to the arid interior of Australia. Where Galahs readily occupy cleared and part-cleared land, Major Mitchell's Cockatoo requires extensive woodlands, particularly favouring Callitris, Allocasuarina and Eucalyptus. In contrast to other cockatoos, Major Mitchell pairs will not nest close to one another; in consequence, they cannot tolerate fragmented, partly cleared habitats, and their range is contracting.

In the Mallee region of Victoria where the Galah and Major Mitchell's Cockatoo can be found to be nesting in the same area, there has been on occasion where the two species have interbred and produced hybridised offspring[4]

Aviculture

Cookie, a cockatoo that is 78 years old, housed in Brookfield Zoo

One Major Mitchell's Cockatoo that has become quite famous is "Cookie," a beloved resident of Illinois' Brookfield Zoo near Chicago since it opened in 1934. As of 25 June 2011, Cookie is 78 years old and has retired from actively being displayed. He currently resides in the keeper's office at the Perching Bird House.
