Sedge Warbler in summer
Its song is a noisy rambling warbler compared to the more rhythmic song of the reed warbler.
Male sedge warblers commence singing only a few hours after arriving on their breeding territory. The song is given from a bare perch such as a reed stem or bush.
Song-flights are also performed: while singing, the bird takes off, rises to a height of around 2–5 meters and then after a short circling flight, makes a slow, ‘parachuting’ descent.
They feed on most insects including mayflies, dragonflies, damselfies, grasshopper, bugs and moths.
