Common name: Eurasian Blackcap Scientific name: Sylvia atricapilla

The Eurasian blackcap — Sylvia atricapilla — is one of Europe’s finest songsters, sometimes called the “northern nightingale” for the quality and richness of its song. The male is unmistakable: plain grey-brown above, pale grey below, crowned with a jet-black cap. The female and immatures wear a warm chestnut-brown cap instead.

A typical warbler of woodland edges, scrub, and parks, the blackcap is a summer visitor across most of Europe that winters in sub-Saharan Africa and around the Mediterranean. In Portugal, resident populations have grown, and a remarkable adaptation has emerged: a proportion of the population originating from Central Europe now winters in Britain and Ireland rather than Africa, navigating using a genetically shifted migratory direction.

Its song is a rich, melodious warble that accelerates into a loud, fluting finish — quite distinct from other warblers and often the first clue to its presence in dense vegetation.
