Breeding information

Breeding season: Aug - Jan Eggs: 1 - 2 / nest Incubation period: ? Fledging age: ?

All parasitic cuckoos must obviously adapt their breeding seasons to those of their potential hosts. The host eggs are removed or destroyed and replaced by the cuckoo's. Channel-billed Cuckoos host on birds such as Pied Currawong, Australian Magpie, Magpie-lark, White-winged Chough, Collared Sparrowhawk. They are also known to host on various species of corvids (ravens and crows).

Type: Host Material: Depends on host Height above ground: Depends on host

Like all parasitic cuckoos, Channel-billed Cuckoos do not have their own nests, but lay their eggs into the nests of host birds.

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 43 x 30 mm Colour: Light-brown, with brown speckles Shape: Long tapered oval

The colours and shape of the eggs roughly match those of potential hosts. However, the cuckoos' eggs are usually larger than the hosts' and their chicks stronger than the hosts'. The hosts' chicks are pushed out of the nest by the young cuckoo, if the hosts' eggs had not been destroyed by the female cuckoo in the first place.


Social behaviour: Territorial Mobility: Migratory Elementary unit: Solitary/pair

One of the few diurnal bird species that we have found to also be active at night, especially near full moon.

Channel-billed Cuckoos are known to be fruit eaters and as such they are very adaptable. They liked the mulberries in our garden (see photo below) and also the fruit of Californian pepper trees, both of which are species introduced to Australia by white settlers. They are also fond of the fruit of the native fig tree.

In 2008 we had to defend our mulberries against Channel-billed Cuckoos ourselves; in 2010 a pair of Australian Magpies took up residency in one of our trees and did the job for us. Only when the Magpie chicks were big enough to follow their parents around, they did not chase the cuckoos any longer.

V. Bowe has kindly provided us with a video showing in detail how a pair of Channel-billed Cuckoos raided the nest of a pair of Pied Currawings. The photo displayed below is a capture from the video. The cuckoos attacked the 2-week old chicks despite their parents' attempts to defend them, first breaking their necks by grabbing the chicks' heads and breaking their necks, before throwing them out of the nest for good measure.

Food, Diet

Unlike most other cuckoos, Channel-billed Cuckoos are primarily fruit eaters, but they are known to also take large insects (e.g. stick insects) and there are reports of them feeding on chicks and eggs of other bird species.
