The Dickinson's kestrel, or Falco dickinsoni, is a bird of prey from the falcon family Falconidae, named in honor of John Dickinson, an English physician and missionary. This species, also known as the white-rumped kestrel, is a relatively small and robust kestrel with a distinctive large, square head. Adults measure between 27 to 30 centimeters in length, with a wingspan of 61 to 68 centimeters, and weigh from 167 to 246 grams. The females are marginally larger and heavier than the males. Their plumage is predominantly dark grey, with a paler head and rump. The tail features grey with narrow black bars and a broad subterminal band, while the underside of the flight feathers are barred. The cere and feet are a striking yellow, with bare yellow skin encircling the eye. The bill is dark grey, and the eyes are a deep brown. Juvenile birds present a grey-brown coloration with barred flanks, lacking the paler head and rump of adults, and have a greenish cere and eye-ring.

When identifying Dickinson's kestrel, look for the pale head and rump contrasting with the darker grey body. The yellow cere and feet, as well as the yellow skin around the eye, are key features. In flight, observe the barred underside of the wings and the broad subterminal band on the tail.

This kestrel favors savanna and open woodland habitats, particularly those that are swampy and near water. It has a strong association with miombo woodland and is often seen around palm trees, such as Hyphaene and Borassus species, as well as baobab trees. It can also be found in coconut plantations in certain regions.

The Dickinson's kestrel's range extends across much of Mozambique, Zimbabwe, Zambia, and Malawi, with its presence also noted in northeastern South Africa, northern Botswana, northeast Namibia, eastern Angola, southern Democratic Republic of the Congo, and parts of Tanzania. It is an occasional visitor to Kenya, with a total range of about 3.4 million square kilometers.

This kestrel typically hunts from a perch rather than by hovering. It preys on large insects like grasshoppers, as well as lizards, amphibians, and occasionally birds, bats, rodents, and snakes. It is known to be attracted to grass fires, seizing the opportunity to capture insects and other prey in flight.

The Dickinson's kestrel is usually silent but emits a high-pitched alarm and contact call. At the nest, a soft, mewing call is used to attract the young for feeding.

The breeding season varies by region, occurring from July to October in Tanzania and from September to December further south. The nest is a simple scrape, often located in the crown of a dead palm or in a baobab hole, and sometimes in an old Hamerkop nest. It is placed 2 to 18 meters above the ground. The female lays one to four cream-colored eggs with reddish-brown markings and incubates them for at least 30 days. The fledging period for the young is approximately 33 to 35 days.

The diet of Dickinson's kestrel is predominantly composed of large insects, with grasshoppers being a staple. It also consumes a variety of other prey including lizards, amphibians, and occasionally birds, bats, rodents, and snakes.
