During the 20th century, however, it has expanded its range to the west. Its varied song contains masterful mimicry and is performed from a song perch in a bush or from a small tree. This song virtuoso resembles Eurasian Reed-warblers and Marsh Warblers, from which it is extremely difficult to distinguish. The short wings are the best characteristics apart from its song.
