A striking black and white wagtail with black upperparts contrasting with white underparts, a white supercilium and a white patch in the folded wing. Juvenile birds are greyer, while birds of the nominate subspeciesshow grey flanks. They are long.
The African pied wagtail inhabits subtropical or tropical seasonally wet or flooded lowland grassland, rivers, and, sometimes, freshwater marshes. In some areas it is commensal with humans in towns and villages.
Biology
In Malawi African pied wagtails start breeding before the rains and continue to breed into the rainy season, they breed during six months of the year peaking in March and October. Both the males and females participate in nest building but only the female incubates but both sexes feed the young. The mean clutch in Malawi was found to be 3.9 eggs. The African pied wagtail is monogamous, the cup-shaped nest is lined with grass and feathers and is usually situated near water in a convenient tangle of sticks. In settlements the nest may be located on buildings. The nests of the African pied wagtail are parasitised by the red-chested cuckooCuculus solitarius and the diderick cuckooChrysococcyx caprius. While chicks have been recorded as prey of Burchell's coucalCentropus burchellii. The African pied wagtail is mainly insectivorous but also feeds on other invertebrates, grass seeds, tadpoles, small fish and scraps of human food.
Etymology
The scientific binomial for the African pied wagtail is Motacilla aguimp; Motacilla, the name of the genus containing all but the forest wagtail of Asia, is from the Latin for a “little mover” while the specific nameaguimp from the French for “with a wimple” which refers to the black hood of the African pied wagtail.
Taxonomy and subspecies
Among the wagtails the African pied wagtail is most similar in appearance to the recently discovered Mekong wagtail but genetic evidence suggests that the two are each other's closest relatives and are each just as related to other black and white wagtails such as the white wagtailM. alba complex or the white-browed wagtailM. maderaspatensis. There are currently two recognised subspecies of the African pied wagtail.
