The male is a gaudy medium-sized parrot, dark green above with a red cap, lime green cheeks and rump, blue-purple breast and red underparts. The female is duller, with a greenish crown and cheeks and pale mauve underparts. Both have a distinctive long pale bill, with a long upper mandible, giving them the common name of Hookbill. They are known as King Parrots in WA. Their flight is undulating and fluttering. When disturbed, they will fly to the top of nearby trees and perch in a typical upright stance, calling loudly.
