Eastern Crowned Warbler

The eastern crowned warbler is a medium-sized, rather robust, brightly coloured leaf warbler, dark olive-green above and white below, with a strong head pattern of dark grey lateral crown stripes and an indistinct yellowish median stripe. The square tail shows a slight fork (Wikipedia, general species account).

It breeds in eastern Siberia from the Argun River eastwards and southwards into western Manchuria and central Sichuan, the Korean Peninsula and Japan, and winters in South-east Asia from eastern India and Bangladesh to Java. It forages quite low in vegetation and joins mixed flocks of small birds in winter (Wikipedia, general species account).
