This grass warbler occurs widely in tropical Africa. Its black moustache-like stripe and broad, rounded dark tail are distinctive. Records in southern Africa are localized to tall grass near streams and wetlands.
A fairly large, plain warbler with a broad, rounded dark tail. A black moustache-like stripe runs beside the bill, while the breast and back are unstreaked.
In the southern African atlas region, it is solitary and skulking, hiding in tall grass, bracken, or other dense herbs on marshy ground near streams. It is easier to see when it sings from the top of a tall plant early or late in the day.
