Hume's Leaf Warbler

Hume's leaf warbler is a very small, active insect-eating warbler with greenish upperparts and off-white underparts. A long supercilium, crown stripe and yellow-edged wing feathers resemble those of the yellow-browed warbler, but Hume's has duller colours, one strong pale wing bar, only a faint second bar, dark legs and a dark lower mandible. It breeds in inner Asian mountains, winters chiefly in India and builds its nest on the ground. (Wikipedia, general species account)
