カオグロバンケン Centropus melanops

A large, long-tailed bird of forest tangles in the lowlands and lower mountains of the southern Philippines. Distinguished by black belly and tail, chestnut wings, cream color from the upper back and chest up to the top of the crown, and a triangular black mask on the face reaching a point at the back of the head. No other similar species in range. Skulking and more often heard than seen. Gives a deep, rapid “wup-wup!” or a lazy, upslurred “woooop!”
