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...

With luck
About 10% of wildlife watchers report a Bornean Ground-Cuckoo sighting in Kinabatangan Wildlife Sanctuary on a given day, based on 194 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 88th most-seen of the 231 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.

GBIF citizen-science records
It is estimated from how often the Bornean Ground-Cuckoo is recorded against all the birds logged in Kinabatangan Wildlife Sanctuary (194 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.
