How to identify

The Mute Swan is a very large white waterbird. It has an S-shaped neck and an orange bill with a black base and a black bump. It flies with its neck outstretched, making regular, slow wingbeats. The population in the UK has increased recently, perhaps due to better protection of this species. The problem of lead poisoning on lowland rivers has also largely been solved by a ban on the sale of lead fishing weights. Some birds stay in their territories all year, while others move long distances and form winter flocks. In cold weather, some birds arrive from Europe into eastern England.

Did you know?

Newly hatched cygnets often hitch a ride on their parents’ backs for warmth, protection and to save energy. Paddling is tiring work when you’re only the size of a grapefruit!

Where and when to see them

Mute Swans live in the UK all year round and are widespread across the UK. You could see one on almost any stretch of fresh water, including lakes, rivers, canals and urban park ponds.

Behaviour

One of the UK’s most iconic and familiar birds, often seen gliding across village ponds or cruising down canals. But don’t let their serene appearance fool you! During the breeding season they’re incredibly protective of their patch, and will see off almost anything that gets too close, from rival swans to curious ducks.

Mute Swans spend much of their day searching for food, dipping their heads underwater and sometimes tipping forwards so that only their tail feathers poke up above the surface. They feed mainly on aquatic plants, but also graze on grass in nearby fields and meadows.

Call/song

Despite their name, Mute Swans aren’t actually silent. They often grunt softly while feeding and will hiss loudly if disturbed – especially when protecting their young. While flying, their wings make a dramatic whooshing sound, so you might hear them coming before you see them!

Nesting

Each spring, pairs perform a beautifully synchronised courtship display out on the water, bowing to each other with wings held aloft, before entwining their necks, often forming a heart shape.

Together, the pair builds an impressive nest from reeds and other plant material, usually hidden among waterside vegetation. The female lays a clutch of four to seven eggs, which she incubates while her partner stands guard.
