The mute swan has an orange beak once fully adult, as compared to the other two species native to the UK, the Bewick and the Whooper swans. The Bewick has a predominantly yellow beak and the whooper has a black beak with a strong yellow triangular section. When cygnets, the mute swan is grey in colour and has a black beak which only becomes orange after losing its cygnet feathers and reaching maturity.
