| Cygnus columbianus (Ord, 1815) |
The Whistling Swan (C. c. columbianus) is the nominate North American form, and the Bewick's Swan (C. c. bewickii) is the European subspecies. The latter is named after the engraver Thomas Bewick, who specialised in illustrations of birds and animals.
Bewick's is the smallest of the three British swans, similar in appearance to the Whooper Swan, but smaller, shorter-necked and with a more rounded head shape, with variable bill pattern, but always showing more black than yellow (the other way round with Whooper Swans). The bill pattern for every bird is unique, and scientists make detailed drawings of each and give them names to assist with studying this species.
Their breeding habitat is wetlandFlorida, USA, with an endangered American Crocodile. In physical geography, a wetland is an environment "at the interface between truly terrestrial ecosystems. and truly aquatic systems. making them different from each yet highly dependent on both" (Mitsc. They pair for life, and their cygnets stay with them all winter; they are sometimes joined by offspring from previous years.

Populations breeding in eastern Russia (roughly east of the Taimyr Peninsula) winter in Japan and China; these are sometimes separated as the race C. c. jankowski, but this is not widely accepted as distinct, most authors including them in C. c. bewickii.
They overwinter in England and Ireland, especially in the wildfowl reserves of the Royal Society for the Protection of Birds and of the Wildfowl and Wetlands Trust.
These birds feed mainly by grazing on farmland. They have a high pitched honking call.
