The black saw-wing, also called the blue saw-wing or black rough-winged swallow, is an African swallow noted for the tiny serrations along the outer primaries that can make a faint buzzing sound in flight. It is a sleek, uniformly dark swallow with a subtle steel-blue sheen, most often seen coursing low over forest edges and streams. Pairs are typically monogamous and often nest in cavities or small burrows in banks or road cuttings. It is widespread and adaptable in montane regions.
