The sedge warbler is a medium-sized warbler of marshes, reedbeds and wetlands that can be spotted singing from perches on reeds and willow bushes. A great mimic, the male sedge warbler introduces random phrases into its repertoire, never singing the same song twice; he attracts more mates the more phrases his song has. Sedge warblers are summer visitors to the UK, breeding in wetland habitats from April onwards.
