what is it?

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).
