About the Radde's Warbler

Radde's warbler (Phylloscopus schwarzi) is a leaf warbler which breeds in Siberia. This warbler is strongly migratory and winters in Southeast Asia. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific schwarzi commemorates German astronomer Ludwig Schwarz (1822–1894).

This is a warbler similar in size to a willow warbler. The adult has an unstreaked brown back and buff underparts. There is a very long prominent whitish supercilium, and the pointed bill is thicker than that of the similar dusky warbler. The legs are paler than those of the dusky warbler, and the feet look large, reflecting the more terrestrial lifestyle of this warbler. The sexes are identical, as with most warblers, but young birds are yellower below. The call is a soft chick.

Radde's warbler breeds in southern parts of Central and Eastern Siberia as far east as Korea and Manchuria. It is a migratory species and spends the winter in Bangladesh, Cambodia, Laos, Myanmar and Thailand. In its breeding range, Radde's warbler is found in open deciduous woodlands with some undergrowth and bushy woodland... Wikipedia →
