Pale-headed Rosella
Platycercus adscitus
Family: Psittaculidae
Tropical and subtropical woodlands of eastern Australia.
© BirdLife International 2016
Inhabits open woodlands and other mixed habitats, including agricultural and settled areas.
Widely distributed in Queensland and northern New South Wales from Cape York south in the interior to Gundabooka and Warrumbungle National Parks and along the coast to Port Macquarie.
An introduced population existed on Maui, Hawaii, from around 1877 into the mid-1900s. It was reportedly numerous from the 1890s until at least the 1920s. The cause and timing of its disappearance are unknown.
Identification
A mostly blue-and-yellow parakeet, but highly variable in the balance, distribution, and intensity of those colors. Northern populations tend to be more extensively yellow.
True to its name, the head is predominantly whitish or yellow. The upperparts are otherwise mostly scaly with large black feather-centers fringed with yellow or aqua-blue. The rump is usually bluish in southern population and yellow in the north.

The underparts are mostly bluish with red undertail coverts. However, the throat and chest can be either yellow or blue. Northern birds typically have a yellow chest and contrasting blue throat. Southern birds tend to be yellow above and blue below, but the location of the transition varies.
The intensity and tones of colors throughout the plumage also vary widely.
The wings and tail are mostly blue.
