The black-browed reed warbler is a small reed warbler, similar to and closely related to the more widespread Eurasian reed warbler. It was first described by Robert Swinhoe in 1860. The cached species account gives no detailed description of its plumage (Wikipedia, general species account).
It breeds from eastern Mongolia and south-eastern Russia to eastern China and Japan and winters in South-east Asia. It forages close to the ground inside undisturbed reedbeds. SoIB 2023 lists it as a winter migrant in India but gives no trend or priority (Wikipedia, general species account; SoIB 2023).
