Scythrops novaehollandiae

General description: 

He call of the Channel-billed Cuckoo, a loud 'kawk' followed by a more rapid, and weaker 'awk-awk-awk...', is as distinctive as the bird's appearance. The call may be given when perched, but is most often given in flight. Apart from the Channel-billed Cuckoo's large size, its massive pale, down-curved bill, grey plumage (darker on the back and wings) and long barred tail make it difficult to confuse it with any other bird. In flight the long tail and long wings give the bird a crucifix-shaped (cross-shaped) silhouette. Young Channel-billed Cuckoos have more mottled buff, brown and grey plumage. Although they are not nocturnal birds (night birds) in the strict sense, Channel-billed Cuckoos are notorious for calling all night long during the breeding season. This species is sometimes known as the Storm-bird or Stormbird.

Conservation status: 

Not Threatened.

Taxonomy:

    Scythrops novæ Hollandiæ Latham, 1790, New South Wales. Monotypic. (source: Handbook of the Birds of World)
Distribution: 

Distribution:

    Breeds in Sulawesi, Buru and Flores, and N & E Australia; rarely occurs in Tasmania. Winters in Moluccas, Lesser Sundas, Aru Is, New Guinea and Bismarck Archipelago.
Habitat: 

It is found in tall open forests, usually where host species occur.

Trophic strategy: 

Insects, mainly caterpillars, also flying ants. Gleans prey from foliage, branches or bark.

Reproduction: 

Aug-Sept. The Channel-billed Cuckoo lays its eggs in the nests of the Australian Magpie, Gymnorhina tibicen, the Pied Currawong, Strepera graculina and members of the crow family (Corvidae). Unlike many other cuckoos, the young birds do not evict the host's young or eggs from the nest, but simply grow faster and demand all the food, thus starving the others. Often the adult female will damage the existing eggs in the nest when she lays her own and she may even lay more than one egg in a single nest.
