The blue-crowned racket-tail (Prioniturus discurus) is a parrot found on all the larger islands of the Philippines except Palawan and Panay islands. It is 27 cm, basically green with a blue crown, bluish undertail, whitish beak, and dark underwings with green coverts. The blue-headed racket-tail (P. platenae) was formerly included in this species.
