Tundra swans (Cygnus columbianus)
Tundra swans are on their way back to North America's high tundra, here stopping to rest a while before continuing their journey.
Swimming in a pond with Canada geese
Tundra swans eat aquatic plants, tubers and roots as well as shellfish. In some places they also eat grains they find on farms.
Four swans a-swimming and one goose
They look meek and mild but they can be ferocious if threatened.
We have three kinds of swans in Ontario. Many Mute and Trumpeter swans are here all year round, but these Tundras migrate between the Arctic and the Atlantic coast so will not be here very long.
Added later in responce to MB: Tundra swans do look a lot like trumpeter swans. One telltale sign on some Tundra swans is the yellow teardrop on their eyes. They don't all have the yellow teardrop though. It may be something that happens as the tundra swans age. Dunno. You can see the yellow teardrop on the lead swan in the first photo.
