Sedge Warblers are one of the commoner warblers in the UK, albeit limited mainly to reed-bed. Possibly slightly easier to see than the other major reed specialist (the reed warbler) it does share the disadvantage of all reed-bed species that it very much depends on how obliging the individual is on how easy they are to get a look at - they can vary wildly between skulking and singing from prominent positions.  This is a Summer migrant, and so only present for half the year, but can be differentiated from the Reed Warbler by the prominent pale eye-stripe and more mottled plumage.  Despite the name, it's not in any way confined to sedges, and can be found in much the same habitat as the Reed Warbler.
