Flocks of these feral parrots are a regular and noisy feature of this part of the foothills. This is one of four that chose to serenade us this morning from a roost high in a large eucalyptus (sorry, I don't have a telephoto lens so this is a grainy image). Their raucous and persistent call is what led me to id it as this species. Please correct this identification, if I am wrong.
