Description
At 58 - 65 cm, the Channel-billed Cuckoo is the largest parasitic cuckoo in the world. Apart from its large size, its massive pale, down-curved bill, grey plumage (darker on the back and wings) and long barred tail, make it impossible to confuse it with any other bird. In flight the long tail and long wings give the bird a crucifix-shaped silhouette. The 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.

Young Channel-billed Cuckoos have more mottled buff, brown and grey plumage. (I definately saw a young one then..:-)

Distribution and Habitat
The Channel-billed Cuckoo migrates to Australia from New Guinea and Indonesia between August and October each year. It is found in tall open forests, in northern and eastern Australia, usually where host species occur. The birds leave Australia in February or March. (That makes me doubly fortunate to have seen him,-he'll be back across the ocean anytime now....:-)

Food and feeding
The favoured foods of the Channel-billed Cuckoo are native figs and native fruits, though some seeds, insects and even baby birds are also taken. The birds take figs from the tree with their massive bills.
