Sedge Warbler

Acrocephalus schoenobaenus


The Sedge Warbler is a medium-sized warbler of marsh, reedbeds and wetlands, which 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 and attracting more mates the more phrases it has. Sedge Warblers are summer visitors to the UK, breeding in wetland habitats from April onwards.

How to identify
