Notes
Common crane, although occurring in fluctuating numbers as a scarce spring and autumn migrant through Britain, with occasional individuals or pairs wintering or summering, has only established a single breeding population, in the Norfolk Broads (see Cranes in Britain for more details); the species was thought to be quite widespread in the Middle Ages, but the term 'crane' was also often applied to grey heron, making a reliable determination of historical status difficult.
