Golden-winged Sparrow

With its long curved bill, this uncommon Sumatran mountain forest endemic is unique within its limited range. Forages alone or in pairs, often in dense undergrowth where it can be difficult to see; listen for its song, a well-spaced series of even, clipped whistles that sound like they should be coming from a small owl. If lucky enough to catch a glimpse, look for a streaky dark brown body, very short tail, and bright white throat.

Tiny stump-tailed flycatcher; one of the smallest birds on earth. Minute size and compact body give it a unique appearance, in some ways looking more like a bumblebee than a bird. Whitish underparts with green back, gray head, and white spectacles. Found in mature and secondary rainforest, especially in areas with tall trees. Usually perches in the rainforest midstory and can be tricky to spot. Its song is a soft pair of short trilled notes “trrr-trrr,” sounding rather insectlike.

Tiny, nondescript, gray bird with a small, sharp bill. Most notable for its lack of distinct marks or coloration! The underparts vary geographically, from whitish to rich buff. Found in savanna and broadleaved woodland. Usually in small, active flocks. Most common vocalization is a series of high-pitched “tsu-tsu-tsii” triplets. Similar to Mouse-colored and Southern penduline-tits, but paler below and browner above than Mouse-colored, and lacks the black facial marks of Southern.
