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. 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 other birds. The African pied wagtail is mainly insectivorous but also feeds on other invertebrates, grass seeds, tadpoles, small fish and scraps of human food.
