While wintering in Africa, the corn crake occupies dry grassland and savanna habitats, occurring in vegetation 30–200 cm (0.98–6.56 ft) tall, including seasonally burnt areas and occasionally sedges or reed beds. It is also found on fallow and abandoned fields, uncut grass on airfields, and the edges of crops. It occurs at up to at least 1,750 m (5,740 ft) altitude in South Africa.[3] Although it sometimes occurs with the African crake, that species normally prefers moister and shorter grassland habitats than does the corn crake.[5] On migration, the corn crake may also occur in wheatfields and around golf courses.[3]
