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.

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....

Possible
About 20% of wildlife watchers report a Chestnut-breasted Malkoha sighting in Kubah National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 92 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Chestnut-breasted Malkoha in Kubah National Park on a given day, against about 10% in May–July, October and December, the lowest months. January–February, September and November have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Chestnut-breasted Malkoha sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 15
Of the 15 parks where we can rate Chestnut-breasted Malkoha sightings, Kubah National Park ranks 7th at about 20%. The best odds are in Way Kambas National Park (Indonesia, about 30%), Danum Valley Conservation Area (Malaysia, about 30%) and Sepilok (Malaysia, about 30%).

GBIF citizen-science records
It is estimated from how often the Chestnut-breasted Malkoha is recorded against all the birds logged in Kubah National Park (15 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.
