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 is a warbler similar in size and shape to a chiffchaff. The adult has an unstreaked brown back and buff underparts. There is a prominent whitish supercilium, and the bill is fine and pointed. The sexes are identical, as with most warblers, but young birds are more olive-tinged above. Like most warblers, it is insectivorous, but will take other small food items, including berries.
The song is a monotonous whistle, and the call is a harsh check. The call is often the first clue that this typically skulking species is present, away from the breeding grounds.
