Long-tailed Sibia
Heterophasia picaoides
Truly long-tailed, even for a sibia, this bird appears rather dainty and small-headed in comparison with most of its relatives. Gray overall, darker on the wings and tail. Mostly lacks the contrasting patterns of other sibias, with only a small white patch near the wingtip. Forages in flocks in open hill forests, edges, and adjacent scrubby second growth. Despite striking appearance, often heard before it’s seen: listen for its loud chittering rattle.
Short-tailed Parrotbill
Suthora davidiana
A tiny pingpong ball of a bird, this parrotbill flits amongst bamboo stands, usually in hilly mixed forest. Tends to be quiet and retiring but can small roving flocks often be detected by chattering twitter. Small and brownish overall, with a black throat and an orange-toned head. Short tail (unusual amongst parrotbills) gives it a bulbous-headed appearance.
Yellow-browed Bunting
Emberiza chrysophrys
Small, modestly attractive bunting of brushy areas and open forests. Brown overall with a paler belly and bright yellow-suffused supercilium. Male has mostly black head, female has a predominantly brown head, but the sexes are otherwise rather similar. Head pattern recalls Rustic and Tristram's Buntings, but neither has yellow in the supercilium. Largely solitary, but may appear in small flocks on migration.
