The Mute Swan (Cygnus olor) is a large, distinctive water bird, and the commonest swan in Britain. The adult has pure white plumage, black legs and an orange-red bill. While swimming the birds hold their neck in a distinctive and elegant curve. It is called a mute swan because it doesn't make any noise, although when threatened it will hiss with its beak wide open and attack people fearlessly showing incredible arrogance as though aware of its Royal protective status in Britain.
