Informations supplémentaires

The smallest swan in the UK, the Bewick arrives in Britain in mid-October after spending the breeding season in Siberia. It has more black on its bill than mute and whooper swans and is considerably smaller and more like a goose in shape. Increasingly threatened by loss of habitat and man's activities, and with significant numbers in the UK, it is on the Amber List. Each swan can be identified by their individual bill pattern.
