Though swans are in the same family as ducks and geese, Anatidae, there are none native to North America. There is, however, one species that’s distributed around southern South America: the Black-Necked Swan. Interestingly, swans in the Northern Hemisphere are usually all-white, while this and other Southern Hemisphere species have at least some black on the feathers.
The species we do have in North America, the Mute Swan, was introduced from Europe to here and Australia. Despite its name, it is not mute, although its calls do not carry well over water. It can be considered an invasive species, as it is very agressive and can out-compete native water birds.
