At 9.5-11 cm long and weighing 4-9 g it is distinctly smaller than a Chiffchaff but slightly larger than Pallas's Leaf Warbler. Like many other leaf warblers, The Yellow-browed Warbler has overall greenish upperparts and white underparts. It also has prominent double wing bars formed by yellowish-white tips to the wing covert feathers (a long bar on the greater coverts and a short bar on the median coverts), yellow-margined tertial feathers, and long yellow supercilium. Some individuals also have a faint paler green central crown stripe though many do not show this.

Habitat and Distribution

This is a bird of lowland and montane forests and woodlands. In winter it may also be found in more open woods. Its breeding range extends from west of the Ural Mountains to eastern Siberia, Mongolia and northeastern China. Its winter habitat is lowland broadleaf or coniferous forest, from West Bengal and Assam in northeastern India east through southern China to Taiwan, and south to the Malay Peninsula. In summer, it occurs at altitudes of up to 2,440 m, and in winter, up to 1,525 m.


The Yellow-browed Warbler is insectivorous.


The nest is built in dense vegetation often at the base of a tree or old stump; two to four (occasionally more) eggs are laid, hatching after 11-14 days, with the chicks fledging when 12-13 days old.

Calls and Songs

Its song is a high pitched medley of whistles; the call is piercing, often disyllabic `tseeweest`, strikingly loud for the bird's small size.
