The Channel-billed Cuckoo (Scythrops novaehollandiae) is a species of cuckoo in the Cuculidae family. It is monotypic within the genus Scythrops. The species is the largest brood parasite in the world, and one of the largest cuckoos.
It is found in Australia, Papua New Guinea and Indonesia, additionally it is vagrant in New Caledonia and New Zealand.[1][2] The species is migratory over part of its range. There are three subspecies, the nominate Scythrops novaehollandiae novaehollandiae of Australia, New Guinea and the Moluccas, Scythrops novaehollandiae fordi in Sulawesi and Scythrops novaehollandiae schoddei in the Bismarck Archipelago.[3] Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. The species is listed as least concern by the IUCN.[4]
Description
The Channel-billed Cuckoo is a massive cuckoo, between 58-66 cm long, with a large slightly curved bill. The bill is straw-coloured and reminiscent of the bills of hornbills, in fact the bird is sometimes erroneously referred to as a hornbill.[5] The plumage of the adult is pale grey on the head, chest, belly and back, becoming paler and barred lower down on the belly. The wings are darker grey with dark tips on the feathers. The tail is dark grey on top and barred underneath with a black band and white tip at the end. The feet and legs are black, and the eye is surrounded by prominent red skin.
The juvenile is similar to the adult but has pale tips to the feathers of the wings, and the rest of the plumage is buff instead of pale grey. The bill is less massive and the skin around the eye is not red.
