The black-and-yellow broadbill (Eurylaimus ochromalus) is a species of bird in the typical broadbill family Eurylaimidae. A small, distinctive species, it has a black head, breastband, and upperparts, a white neckband, yellow streaking on the back and wings, and vinous-pink underparts that turn yellow towards the belly. The beak is bright blue, with a green tip to the upper mandible and black edges. It shows some sexual dimorphism, with the black breastband being incomplete in females.
Native to Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand, it inhabits evergreen forest, dipterocarp forest, swamp forest, heath forest, and forest edge, along with secondary forest and plantations that contain large trees. Mainly inhabiting lowlands, the species is found up to elevations of 1,220 m (4,000 ft). The black-and-yellow broadbill is mainly insectivorous, but also feeds on molluscs and incidentally takes fruit.
The black-and-yellow broadbill breeds during the dry season throughout its range, with both sexes helping build a large, untidy, pear-shaped nest out of moss, fungal mycelia, and leaves. Eggs are laid in clutches of two or three, sometimes containing a fourth runt egg, and are incubated by both sexes. The species is listed as near-threatened by the IUCN because of a decline in its population caused by habitat loss. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black-and-yellow Broadbill is recorded against all the birds logged in Kinabatangan Wildlife Sanctuary (708 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.
