 The corn crake is <unk> with the African crake on the wintering grounds , but can be distinguished by its larger size , paler upperparts , tawny <unk> and different underparts pattern . In flight , it has longer , less rounded wings , and shallower <unk> than its African relative , and shows a white leading edge to the inner wing . In both the breeding and wintering ranges it is unlikely to be confused with any other rails , since <unk> species are smaller , with white markings on the upperparts , different underparts patterns and shorter bills . A flying corn crake can resemble a <unk> , but its chestnut wing pattern and dangling legs are diagnostic .
