About

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.

What to look for

Sedge warblers are sandy brown. They are paler underneath and streaky above, with a dark, streaked cap. They have a distinctive white eyestripe.

Where to find

A widespread summer visitor.
