The images shows a Rosa Bourke one of several man developed colour varieties. The wild colour form is a dove grey to fawn with a slight pink on the lower abdomen and blue tints on the face, rump and flight feathers. They are members of the Grass Parakeet genus closely related to budgerigars.
A flock can migrate long distances to find water and seeds,. The mature males have blue feathers above their beaks, while the females and juveniles have little or no blue colouring.
They nest in trees and are very territorial when breeding.
They have been kept and bred as cage birds because of their beautiful plumage, placid nature and fairly quiet calls.
