About Falco concolor Temminck, 1825
Falco concolor Temminck, 1825 is an elegant bird of prey, measuring 32–37 cm in length with a 78–90 cm wingspan. It has a body shape similar to a large Eurasian hobby or a small Eleonora's falcon, featuring long pointed wings, a long tail, and a slim body. Adult individuals are blue-grey, and do not have the black underwing coverts that characterize Eleonora's falcon. Juvenile Falco concolor resemble large juvenile Eurasian hobbies, or small juvenile Eleonora's falcons. A dark trailing edge along the wings and tail distinguishes juvenile Falco concolor from juvenile Eurasian hobbies, and it lacks the underwing contrast created by the dark coverts of the larger Eleonora's falcon. This species occurs across Southwest Asia and North Africa. It breeds on islands, and on coastal or desert cliffs, ranging from Libya to Pakistan. It is a long-distance migrant that winters in east Africa, ranging south to Madagascar and southeastern South Africa. Increasingly regular recent sightings paired with a lack of older historical records indicates that its wintering range has expanded southward over recent decades. It is a rare vagrant in areas north of its breeding range.
