Bristled Grassbird

The bristled grassbird is a large brownish warbler, 16 to 17cm in males and 14.5 to 15.5cm in females, with a dark-streaked crown and back, a buff brow, a pale underside and a white-tipped tail. It is sometimes babbler-like in appearance and is secretive, but males rise above the grass, zig-zag and then parachute back down. It forages for insects within grass clumps in tall grass in marshy areas (Wikipedia, general species account).

It breeds from May to September, building a ball of grass for a nest with four or five eggs incubated by the female. It is endemic to the Indian subcontinent, including Nepal, Bangladesh, India and Pakistan, and may be migratory. It was formerly placed in the genus Chaetornis (Wikipedia, general species account).
