Raffles's malkoha (Rhinortha chlorophaea) is a species of cuckoo (family Cuculidae). It was formerly often placed in Phaenicophaeus with the other malkohas, but it appears to not be very closely related to the true malkohas. It exhibits several autapomorphies and sexual dimorphism (which its presumed relatives all lack).
It is found in Brunei, Indonesia, Malaysia, Myanmar, and Thailand. It was once found in Singapore but is now considered extirpated. Its natural habitat is subtropical or tropical moist lowland forests. Its diet consists of insects, including caterpillars, cicadas, crickets, beetles, and locusts.
During courtship, the male Raffles's malkoha has been observed to stand on the base of the female's outstretched wings and hold a frog in its bill. It is unclear whether the frog is a gift to the female or whether the male keeps it afterward. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Raffles's Malkoha is recorded against all the birds logged in Danum Valley Conservation Area (557 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.
