The Black Saw-wing is a dark swallow with a long forked tail. It flies over forests and plantations and is native to wooded parts of Africa. The amount of pale color on the underwing varies geographically.
It is all black with a long forked tail. The underwing is dark in most areas, but some regional forms have a white or pale-gray patch at the front of the underwing.
It flies over forests, plantations, and thick woodland and is sometimes seen perched on a dead tree. Its flight is described as weaker and more fluttery than that of a typical swallow.
