The chestnut-breasted malkoha (Phaenicophaeus curvirostris) is a species of cuckoo in the family Cuculidae. Found in Southeast Asia from Myanmar through to eastern Java, the Philippines and Borneo, it is a large cuckoo measuring up to 49 cm (19 in) with grey and dark green upperparts and chestnut underparts, and a large curved pale upper mandible. The male and female are similar in plumage. Unlike many cuckoos, it builds its nest and raises its own young.
The chestnut-breasted malkoha was first described from a specimen collected in western Java by English naturalist George Shaw in 1810 as Cuculus curvirostris, before the genus Phaenicophaeus was erected by English naturalist James Francis Stephens in 1815. Its specific epithet is derived from the Latin words curvus "curved", and rostrum "beak". The genus name is derived from the ancient Greek phoiniko- "crimson", and phaes "eyes" or "face", referring to the red-faced malkoha. However, the 'œ' was transcribed incorrectly as 'æ'.
Five subspecies are recognised: P. c. singularis: from southern Myanmar and Thailand, through the Malay Peninsula and into Sumatra, as well as the Anambas archipelago. P. c.... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Chestnut-breasted Malkoha is recorded against all the birds logged in Kinabatangan Wildlife Sanctuary (118 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.
