The tundra swan is large with pure white plumage, except for a yellow spot below the eye. Its bill is black.
Habitat and Habits
This species was once known as the "whistling swan," although the sounds they make are more reminiscent of geese, or perhaps dogs heard from afar. "Tundra" is a much more appropriate moniker, as this species nests in the extreme northern reaches of North America. They are usually found in open marshes, lakes, or flooded fields. They sometimes forage in agricultural fields.
Reproduction and Care of the Young
Breeding takes place in northern Canada and Alaska. Nests are large mounds of grass on an island or next to a marsh. Both parents care for the young, which usually hatch in late June.
