Mute Swan Facts

In the wild, Mute Swans will usually pair for a long time, although they have been known to change partners on occasion.

They are often quite tame outside of breeding season and accept food from visitors to ponds or parks. They usually eat aquatic plants, although sometimes-aquatic invertebrates are also consumed.

In order to obtain such food, Mute Swans simply plunge their necks into the water.

Sometimes, in places where water has a high mineral content, the swans will have brown colored necks or heads. In deep water, a swan may even tip most of its body under the surface, leaving only its hind end exposed.
