The Dambo Cisticola has a very long black tail, and the breeding male gives a distinctive song and aerial display. In a 1931 survey along the Congo–Zambezi divide, birds bred in open flats with short grass; records extended from Nasondoye to eastern Angola.
Adults have a very long tail that is black in both sexes. Lynes described the breeding male’s distinctive song and aerial display as useful for separating it from related cisticolas. The account focuses on adults in summer plumage.
In January 1931 at Nasondoye, in what is now southern DR Congo, observers recorded a breeding pair and a nest with two eight-day-old young and one addled egg. They found the birds where open flats of short grass occurred and also noted the male’s song and aerial display.
