A reed warbler with a relatively long bill and tail. Museum research supports breeding in Central Asia, although the precise breeding range and habitat remain unresolved.
Compared with Blyth's Reed Warbler, its bill is longer, slightly broader, and duller. Its tail is longer and more graduated, with shorter outer feathers, and its hind claw is longer.
Reidentified specimens collected in Central Asia during the breeding season support that region as its breeding area. Nests, exact boundaries, and habitat are still unresolved.
An extinction-risk assessment has not been added yet.
