The Bornean ground cuckoo (Carpococcyx radiceus) is a large, terrestrial species of cuckoo in the family Cuculidae.

It is threatened by habitat loss. It was formerly considered conspecific with the Sumatran ground cuckoo.
The Bornean ground cuckoo was described as Calobates radiceus by the Dutch zoologist Coenraad Jacob Temminck in 1832 based on a female specimen from Pontianak district in Borneo. In 1840, George Robert Gray established it as the type species of a new genus, Carpococcyx, because Calobates was similar to the fly genus Calobata. Additionally, it is also a junior homonym of the genus Calobates, established by the German naturalist Johann Jacob Kaup in 1829. The specific name, radiceus, is either from the Neo-Latin radius (rod or staff) or radicis (foundation). It is thought to be an error for radiatus or radiosus, with Temminck himself referring to the species by those names in other writings, but the original description does not provide enough evidence to emend...

Rare
Under 5% of wildlife watchers report a Bornean Ground-Cuckoo sighting in Danum Valley Conservation Area on a given day, based on 70 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 168th most-seen of the 258 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January–March, May, August and October
In those months about 10% of wildlife watchers report a Bornean Ground-Cuckoo in Danum Valley Conservation Area on a given day, against under 5% in April, June–July, September and November–December, the lowest months.
2nd of 2
Of the 2 parks where we can rate Bornean Ground-Cuckoo sightings, Danum Valley Conservation Area ranks 2nd at under 5%. The best odds are in Kinabatangan Wildlife Sanctuary (Malaysia, about 10%).
Same family: Cuculidae
The closest relatives of the Bornean Ground-Cuckoo that you can see in Danum Valley Conservation Area (family Cuculidae, Cuckoos) are Raffles's Malkoha (about 30%), Chestnut-breasted Malkoha (about 30%) and Greater Coucal (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bornean Ground-Cuckoo is recorded against all the birds logged in Danum Valley Conservation Area (70 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.
