About

The mute swan is among the heaviest of all flying birds, instantly recognised by its pure white plumage, orange bill with a black knob, and the elegant S-curve of its neck. A familiar sight on rivers, lakes and park ponds, it glides with serene grace.

Despite its name it is not silent, producing hisses, grunts and a distinctive throbbing of the wings in flight.

Behaviour

Mute swans form strong, long-lasting pair bonds and fiercely defend their nest and cygnets, threatening intruders with arched wings and loud hissing. Both parents care for the young, who may ride on the adults' backs when small.

They feed by up-ending in shallow water to reach submerged plants.
