The channel-billed cuckoo (Scythrops novaehollandiae) is a species of cuckoo in the family Cuculidae. It is monotypic within the genus Scythrops. The species is the largest brood parasite in the world, and the largest cuckoo.
It is found in Australia, New Guinea and Indonesia; additionally, it is vagrant in New Caledonia and New Zealand. The species is migratory over part of its range. There are three subspecies, one migratory, the other two resident. The species is listed as least concern by the IUCN.

He gave it the name Scythrops novaehollandiae in 1790. Its generic name is derived from the Ancient Greek skuthro-/σκυθρο- 'angry' or 'sullen', and ops/ωψ 'face', 'eye' or 'countenance'. The specific epithet novaehollandiae means of New Holland, hence Australian. John White, the surgeon-general of the First Fleet to New South Wales, wrote... Wikipedia →

With luck
About 10% of wildlife watchers report a Channel-billed Cuckoo sighting in Daintree National Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 83rd most-seen of the 208 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
February and March
In those months about 30% of wildlife watchers report a Channel-billed Cuckoo in Daintree National Park on a given day, against under 5% in April–June and August, the lowest months. Those are among Daintree National Park's wettest months, with about 290 mm of rain a month against 50 mm in September.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Channel-billed Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 10
Of the 10 parks where we can rate Channel-billed Cuckoo sightings, Daintree National Park ranks 6th at about 10%. The best odds are in Raja Ampat (Indonesia, about 20%), Kakadu National Park (Australia, about 10%) and Royal National Park (Australia, about 10%).
Same family: Cuculidae
The closest relatives of the Channel-billed Cuckoo that you can see in Daintree National Park (family Cuculidae, Cuckoos) are Pheasant Coucal (about 20%), Pacific Koel (about 20%) and Little Bronze Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Channel-billed Cuckoo is recorded against all the birds logged in Daintree National Park (151 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
