The Yellow-browed Warbler is a tiny, energetic leaf warbler of the Siberian taiga that winters mainly in South and Southeast Asia. It is greenish above and whitish below, with two bold wing bars and a long, yellowish supercilium. Its high, piercing call often reveals it. It has become a common autumn migrant in western Europe, where small numbers now also winter.

Did you know?

  • Birds wintering in western Europe are now thought to be a regular migration route, not just vagrants.
  • Its name inornatus means “plain”.

About the species

Identification

A small, greenish-grey leaf warbler: the back is greenish and the underparts pale. A prominent pale supercilium and a dark eye stripe; the wing shows two clear pale wing bars set off by darker areas. The tertial edges, legs and bill base are pale, and the rump is the same colour as the back. The call is a loud, high, Coal Tit-like “tsweest”. It lacks the pale crown stripe and yellow rump of Pallas's Leaf Warbler.

About the habitat

Breeds in taiga of spruce, larch and birch; on migration and in winter many kinds of woodland, parks, gardens, coastal scrub and forest edges.

Diet

Small insects and other arthropods picked from leaves and twigs or snatched in short sallies.

Behaviour

Almost constantly on the move, flitting through the canopy and understorey, often more easily heard than seen. On migration it often joins mixed flocks of tits and kinglets. The song is a high, wheezy whistle, and the call a sharp, carrying “tsweest”.
