Mute Swan - Norfolk Broads - England Stock Image
Description
Mute Swans - Cygnus olor - on the River Ant on the Norfolk Broads in the United Kingdom. The Mute Swan is a Eurasian member of the duck, goose and swan family - Anatidae. Although they tend to be quieter than other kinds of swans, they are not mute, and do vocalize. The Mute Swan is one of the heaviest flying birds, with males (known as cobs) averaging about 12 kg (27 lbs) and females (known as "pens") more than 8 kg (19 lbs). An unusually big Polish cob weighed almost 23 kg (50 lbs), surpassing the longer-bodied Trumpeter Swan to make it the heaviest waterfowl ever recorded. Its size, orange-reddish bill and white plumage make this swan almost unmistakable at close quarters. Surveys done by airplane, however, often mistake the species, creating questionable counts. The most similar species is the Whooper Swan, but it has a yellow and black bill, lacks the curved "swan" neck, is longer and heavier, and lacks the characteristic projection above the bill.
