Cranes are large, long-legged and long-necked birds of the order Gruiformes. Two species occur as wild birds in Great Britain: the common crane (Grus grus), a scarce migrant and very localised breeding resident currently being reintroduced to the country, and the sandhill crane (Antigone canadensis), an extreme vagrant from North America. A third species, the demoiselle crane (Grus virgo), has been recorded on a number of occasions, but these birds have not generally been accepted as being of wild origin.
