Some German birds winter in gardens in the British Isles. Birds from the colder areas of the range migrate, wintering in scrub in western Europe, around the Mediterranean and in Africa. The chicks fledge in 11–12 days, but are fed by both adults for some time after. The female lays four to six buff eggs, which hatch in about 11 days. The blackcap builds a neat cup nest in scrub, often in mature deciduous woodland. The male's song is a rich musical warbling.
It has grey upperparts and paler grey underparts, and the male has a black cap, while the female's is reddish-brown. The Eurasian blackcap ( Sylvia atricapilla) is a typical warbler in Europe, western Asia and northern Africa.
