Fairly common summer migrant from winter grounds in Africa. Found in wide variety of wooded habitats, where often rather sluggish and easily overlooked. Pleasant, rich warbling song much like song of Blackcap but tends to be more even-paced, less emphatic. Appears rather plain brownish overall, without any striking features—in itself a field mark. Note hint of paler eyering, diffuse gray patch on side of neck, and relatively stubby bill for a warbler.
