Pairs defend a breeding territory of open water and tundra up to a half-acre in size and chase off other swans, geese and Long-tailed Ducks. Such encounters can get physical, with the swans tackling and trampling an intruder or grabbing the tail during an aerial defense.

What are the different types of tundra swans?

Two subspecies of this swan are recognized: the “Whistling” Tundra Swan ( Cygnus columbianus columbianus) of North America, and the “Bewick’s” Tundra Swan ( Cygnus columbianus bewickii ), which breeds in the Arctic regions of Siberia and winters in Western Europe and Asia.

What do Swans eat in the wild?

This species of swan is herbivorous, and eats primarily plant matter. They feed on weeds, grasses, sedges, flowers, roots, shoots, and stems. Some of their favorite foods are algae, pondweed, saltmarsh, and more.

What is the difference between tundra swans and Bewick Swans?

The Eurasian subspecies of the Tundra Swan is known as Bewick’s Swan. It is slightly smaller than the North American Tundra Swan and has more yellow on the bill. Individuals are occasionally found in western North America, usually in flocks of Tundra Swans.

Are tundra swans herbivores?

Mainly herbivorous, the Tundra Swan forages in shallow wetlands, seeking aquatic plants and roots as well as some arthropods, worms, and shellfish. It tips its body up and plunges its long neck underwater to forage, or uses its large webbed feet to dig up food items from the muck.

Tundra swans winter on the water and sleep afloat. They are strong and speedy swimmers that take to the air with a running start, clattering across the water’s surface with wings beating.

Where do swans migrate?

Their migrations can overlap areas where trumpeter swans have been nesting or wintering. Eastern tundra swans migrate across the continent to winter on the Atlantic coast. The western population of tundra swans migrates to wintering grounds from Southern British Columbia to Central California. Bewick and Whooper swans are found in Britain.

What predators do swans have?

Swans do not have many natural enemies, and are well equipped to defend themselves against most predators. The main predators are foxes, which from time to time take birds roosting in accessible places. The main threats come from pollution of freshwater areas, lead weights previously used by anglers, fishing tackle, and overhead power lines.
