Rock Kestrel

A slender, medium-sized kestrel, between 30 and 33 centimeters tall. Adult male kestrels weigh between 183g and 254g, while females weigh between 190g and 280g.

The species occurs from Angola, south through the Democratic Republic of Congo as well as Tanzania, further south to South Africa, and in most of the places between. Noticeable places of scarcity include north and north east Namibia, Botswana, south Mozambique and tropical Lowveld, while in Zimbabwe it is restricted to high-lying central and eastern regions. The kestrel is usually associated with arid areas, but may also be found in open and/or semi-arid areas.

Rock kestrels feed on a wide variety of organisms. They eat primarily invertebrates, but have been known to consume rodents, reptiles and birds. Two primary forms of hunting are employed: hover hunting and perch hunting. Hover hunting describes the method whereby the kestrel remains stationary in the air with minimal wing flapping by utilizing updrafts. Hover hunting generally happens at medium to high windspeeds. It is usually small prey (such as insects) which are caught via this method, and are subsequently eaten during flight. Perch hunting is when the kestrel utilizes either natural (for instance cliffs and trees) or artificial (for instance electricity pylons and telephone poles) perches to scan the surrounding area for prey. Rock kestrels have been observed following baboons through grasslands and catching the insect species flushed out. There are also reports of rock kestrels robbing nests for young birds and eating termites on the floor. Their call is a harsh chay-chay-chay, especially when scaring off intruders, unlike the common kestrel's kee-kee-kee.
