Marsh Warbler - European Mockingbird. Birds singing in spring

Bird sounds - Marsh warbler (Acrocephalus palustris). Singing and chirping birds in spring. One of the best European Mockingbird. The Marsh Warbler is best known for the highly imitative song uttered by males, and very occasionally by females. Each male marsh warbler incorporates imitations of a wide range of other birds into its song. Other passerines are most commonly imitated, but the calls of other kinds of bird such as waders, hornbills and pigeons have been noted too. On average, each male bird incorporates imitations of 75 other species into its song, with rather more African than northern species mimicked. All learning seems to take place in the summer the bird is hatched in Europe or Asia, and in its first winter in Africa. The calls of birds heard in subsequent years are not added to the warbler’s repertoire (Wikipedia).
