The Sooty Falcon (Falco concolor ) is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis. Eleonora's Falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species.

This species breeds on islands and coastal or desert cliffs in northeast Africa from Libya to Israel and the Red Sea. It is a long-distance migrant, wintering in east Africa and south to Madagascar. It is a rare vagrant north of its breeding range.

The Sooty Falcon is an elegant bird of prey, 32-37 cm long with a 78-90 cm wingspan. It is shaped like a large Hobby or a small Eleonora's Falcon, with its long pointed wings, long tail and slim body. The adults are blue-grey, and lack the black underwing coverts of the Eleonora’s Falcon. The young bird is like a large juvenile Hobby, or small juvenile Eleanora’s Falcon. Its dark trailing edge to the wings and tail distinguish it from the former species, and it lacks the underwing contrast caused by the dark coverts of the larger falcon.

The Sooty Falcon eats mainly birds, but it will take large insects, such as dragonflies, which are transferred from talons to beak and eaten in flight. It nests on a ledge or on rocks, laying up to four eggs.
