Black-throated Wren-Babbler Turdinus atrigularis

Uncommon wren-babbler of Bornean lowland and foothill forests. Like most other wren-babblers, secretive and difficult to locate as it forages on the ground, usually in small groups. Best detected by its song, which takes two forms. “Short song” is a repetitive series of ten or so clear, hooting whistles, while “long song” can be up to three or four times the length and interspersed with more rising and falling notes. Duetting birds will often add an additional song element, a mellow rolling series of notes along the lines of “dee-dee-dee-da-doo-da-dih-doo.” If seen, note black throat, pale bluish-gray patch behind the eye, black-edged streaking with a “scaly” appearance, and chestnut wings.
