Black-browed reed warbler, Schrenk's Reed Warbler 
(Chích đầu nhọn mày đen, Acrocephalus bistrigiceps)

The black-browed reed warbler (Acrocephalus bistrigiceps) is a marsh-warbler in the family Acrocephalidae.
The bird breeds from eastern Mongolia and south-eastern Russia to eastern China and Japan, and winters in Southeast Asia.

The family is from the name of the genus Acrocephalus from Ancient Greek akros, "highest", and kephale, "head". 
It is possible that the Naumanns thought akros meant "sharp-pointed".
bistrigiceps: Latin bi-: double; striga: furrow; -ceps: -capped (caput head).
