Blyth's Reed Warbler
Acrocephalus dumetorum
It breeds in temperate Asia and easternmost Europe. It is migratory, wintering in India and Sri Lanka. It is one of the most common winter warblers in those countries. It is a rare vagrant to western Europe. This is a medium-sized warbler, 12.5-14 cm in length. The adult has a plain brown back and pale underparts. Like most warblers, Blyth's reed warbler is insectivorous, but will take other small food items, including berries.
