Channel-billed Cuckoo

Channel-billed Cuckoo belongs to cuckoo in the family Cuculidae. It is monotypic within the genus Scythrops. This species is the largest brood parasite in the world, and the largest cuckoo. Captain Arthur Phillip wrote of this (at the time) mysterious bird—calling it the 'psittaceous hornbill'—in his 1789 work The voyage of Governor Phillip to Botany Bay, consulting with ornithologist John Latham and deliberating that it had features of a parrot, hornbill or toucan, though conceding there were no toucans in the region.

24 adults were found to have averaged 684 g (1.508 lb) in body mass. The channel-billed cuckoo has a widespread distribution across northern and eastern Australia, New Guinea, the Bismarck Archipelago, and the islands of eastern Indonesia as far west as Sulawesi. Elsewhere within its range it is migratory. Birds breeding in Australia range from north eastern Western Australia through the Northern Territory and Queensland down into eastern New South Wales as far as Sydney.
