Very rare summer visitor to the UK, 5 pair breeding in a small part of SE England, otherwise widespread across middle Europe.
Prefers thick wetland vegetation, sedges, willow herb and nettles. Sometimes appears in other parts of the UK as a passage migrant.
The Marsh Warbler is very hard to distinguish from the Reed Warbler, however the Reed Warbler only reluctantly leaves reed bed areas, so any sighting outside of this habitat requires careful examination to establish species. The song of the Marsh Warbler consists of mostly mimicry, however it is likely to be different to the Reed Warbler which can in itself aid identification.
Species: A. palustris
