About Acrocephalus bistrigiceps Swinhoe, 1860
The black-browed reed warbler, with the scientific name Acrocephalus bistrigiceps, is a species of marsh-warbler belonging to the family Acrocephalidae. This species was formally first described by Robert Swinhoe in 1860. It was previously grouped into the broader 'Old World warbler' assemblage. This warbler breeds across a range extending from eastern Mongolia and southeastern Russia to eastern China and Japan, and migrates to Southeast Asia to spend the winter. It is closely related to, and similar in appearance to, the more common and widespread Eurasian reed warbler. The black-browed reed warbler forages near the ground within undisturbed reed beds. Like many other wetland bird species, it is a species of conservation concern. This conservation status stems from habitat loss: native marsh vegetation where it lives is being destroyed and replaced by rice paddies and fishponds.
