Dusky Warbler

The dusky warbler (Phylloscopus fuscatus) is a leaf warbler which breeds in the east Palearctic. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific fuscatus is from Latin fuscus "dark".

This warbler is strongly migratory and winters in South Asia and South-east Asia. It sometimes occurs in North America in Alaska, and has also occurred in California.
