The Rock Martin (Ptyonoprogne fuligula) is a small passerine bird in the swallow family that is resident in central and southern Africa. It breeds mainly in the mountains, but also at lower altitudes, especially in rocky areas and around towns, and, unlike most swallows, it is often found far from water. It is 4.7–5.9 in long, with mainly brown plumage, paler-toned on the upper breast and underwing coverts, and with white "windows" on the spread tail in flight. The rock martin hunts along cliff faces for flying insects using a slow flight with much gliding. Its call is a soft twitter.
This martin builds a deep bowl nest on a sheltered horizontal surface, or a neat quarter-sphere against a vertical rock face or wall. The nest is constructed with mud pellets and lined with grass or feathers, and may be built on natural sites under cliff overhangs or on man-made structures such as buildings, dam walls, culverts and bridges. It is often reused for subsequent broods or in later years.
