Sumatran Wren-Babbler

This large swallow has rusty-red underparts, a pale buff throat, and a white leading edge to the underwing that is obvious only in flight. It is mostly resident, although it is also a wet season migrant to the north of its range. Pairs prefer wooded savanna, nesting in banks, termite mounds, and often holes in trees, particularly baobabs. The Mosque Swallow may be confused with the juvenile Rufous-chested Swallow, but it lacks the latter species’ dark “ear-flaps” and buffy forward part of the underwing.

Tiny, drab bird with a sharp bill, a dull olive-green back, and buffy yellow underparts and forehead. Found in lowland rainforest, secondary forest, and sometimes plantations, usually in the canopy. Uncommon and inconspicuous, in pairs or small flocks. Similar to Yellow Penduline-Tit, but much duller and found in different habitat. Could be confused with Tit-Hylia, but duller overall, without streaking on the head and breast. Could also be confused with some dull sunbirds, but has a shorter, deeper-based, and sharper bill. The vocalizations are very high-pitched “sit” notes that are easily missed.

Small, with a long, often fanned tail. Mostly pale orange-red with a gleaming white throat and a black chest with gray sides. Note the small black eye mask. Mostly resident in forest, but sometimes forages in open scrub. Common vocalization is a soft whistle or raspy “me-EE-ow.”
