    Eurasian Blackcap

    Sylvia atricapilla

    Information

    Due to its adaptability, the Eurasian Blackcap faces a favourable future. It is one of our most widespread breeding birds and even enriches parks and gardens in large cities with its clear, sonorous fluting song phrases. This species is a favoured object for studies in bird migration research because a new strategy of autumn migration has established itself for a few decades with part of the breeding birds migrating towards the northwest in the direction of the North Sea and the British Isles instead of the Mediterranean.
