The white-bellied cuckooshrike (Coracina papuensis) is a species of bird in the family Campephagidae. It is found in Australia, the Moluccas, New Guinea and the Solomon Islands.
This species exhibits a short black mask extending from the beak to the eyes (Lores) but not beyond with a fine white rear eye-ring. The head and upperparts including upper wings are pale blue-grey with tail feathers tending towards darker grey. Despite the name, the belly can be white to grey depending on region and subspecies. The subspecies Coracina papuensis robusta can present with a dark morph that has extensive black plumage on the neck and chest that can be barred at the edges. There is little variation between the sexes. Immature birds can have the underparts lightly barred and appear duller than adults with a less distinct black mask. This species can be mistaken for the black-faced cuckooshrike due to similar markings but is smaller with a more compact build.
The white-bellied cuckooshrike has a characteristic call that is described as a peevish ‘kissik kissik’ or ‘quiseek’. It also produces a weak, squealing, slurred, repeating ‘whee-eeyu’ or ‘wee-year’ that has been likened to that of a parrot (Psittacidae). It is often spotted flying due to its distinct undulating pattern of flight where the species gains altitude by flapping its wings then holding its wings stiffly downward to glide.
