About Phylloscopus schwarzi (Radde, 1863)
Radde's warbler, with the scientific name Phylloscopus schwarzi (Radde, 1863), is a warbler that is similar in size to the willow warbler. Adult individuals have an unstreaked brown back and buff-colored underparts. They have a very long, prominent whitish supercilium. Their pointed bill is thicker than that of the similar dusky warbler. Their legs are paler than the dusky warbler's legs, and their feet appear large, which reflects this warbler's more terrestrial lifestyle. As with most warblers, the sexes of Radde's warbler are identical in appearance. Young birds, however, are yellower on their underparts. The call of this species is a soft chick. This species is migratory. It breeds in southern parts of Central and Eastern Siberia, ranging as far east as Korea and Manchuria. It spends the winter in Bangladesh, Cambodia, Laos, Myanmar and Thailand. Within its breeding range, Radde's warbler occurs in open deciduous woodlands with some undergrowth, as well as at bushy woodland margins, often located near water. In its wintering grounds, it occupies forest fringes, thick scrub, and bushy areas near woodland. Like most Old World warblers, this small passerine bird is insectivorous.
