The Bornean whistling thrush is a species of bird in the family Muscicapidae. It is found in Indonesia and Malaysia, where it is endemic to the island of Borneo. Its natural habitat is subtropical or tropical moist montane forests.
Region
Borneo (Maritime Southeast Asia)
Typical Environment
Occurs in the higher elevations of the island of Borneo across Malaysian states (Sabah, Sarawak), Brunei, and Indonesian Kalimantan. It is most often found in subtropical or tropical moist montane forests, especially along shaded, rocky streams and waterfalls. Prefers dense, mossy undergrowth and boulder-strewn ravines where clear water flows year-round. Typically avoids lowland forests and open areas, remaining within closed-canopy, humid habitats. Often uses streamside logs and rocks as hunting perches and retreats to thick vegetation when disturbed.

The Bornean whistling thrush is tied to fast-flowing montane streams and often perches on mossy rocks, flicking its tail while scanning for prey. Its clear, fluty whistles carry far through the forest, especially at dawn. The species is elusive but can be detected by its habit of foraging along streambeds and riverine trails.

Flight Pattern
short rapid wingbeats
Social Behavior
Usually encountered singly or in pairs, holding linear territories along streams. Breeding pairs nest close to water, often in crevices, on ledges, or among roots and mossy banks. They spend much time perched on rocks, repeatedly bowing and flicking the tail while scanning for prey.
Migratory Pattern
Resident
Song Description
A series of clear, fluty whistles delivered from a concealed perch, often at dawn and dusk. Also gives sharp metallic calls when alarmed or during territorial encounters.
Plumage
Mostly dark slaty to blackish-blue with a subtle cobalt sheen and spangling on the head, mantle, and wing coverts. Feathers appear slightly iridescent in good light, giving a scattered blue speckled effect. Plumage is dense and sleek, suited to damp, streamside habitats.
Diet
Feeds primarily on aquatic and terrestrial invertebrates, including insects, larvae, beetles, and snails. Will also take small crustaceans, earthworms, and occasionally small amphibians. Rarely consumes fruits when animal prey is scarce.
Preferred Environment
Forages along shaded, rocky streams, hopping between boulders and along muddy or leaf-littered banks. Often probes crevices, turns leaves, and picks prey from wet surfaces and shallow water.
