Pallas's leaf warbler is one of the smallest Palearctic warblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. It breeds in mountain forests from southern Siberia east to northern Mongolia and north-east China (Wikipedia, general species account).
It is strongly migratory, wintering mainly in south China and adjacent areas of South-east Asia. The female builds a cup nest in a tree or bush and incubates four to six eggs for 12–13 days, with nesting from June to July. The chicks fledge at 12–14 days and are fed mainly by the female at first. It is insectivorous (Wikipedia, general species account).
