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. 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.
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.
