What are the types of swans?

There are about seven types of swans.

1. Mute Swan -- the entirely white swan that is found mostly in Europe and Asia; this is the type of swan that is revered in a number of cultures and that has been immortalized in The Ugly Ducking and Swan Lake.

2. Black Swan -- found mostly in southern Australia and has been reintroduced into New Zealand

3. Black-necked Swan -- native to South America

4. Trumpeter Swan -- found in North America, particularly in Alaska

5. Whooper Swan -- essentially the European/Asian counterpart to the Trumpeter Swan

6. Tundra Swan -- split into two types (Bewick's Swan and the Whistling Swan); large numbers found in Arctic areas

7. New Zealand Swan -- extinct; fossils suggest that it was a subspecies of the Black Swan

And then there is of course the Natalie Portman Swan -- the Swan Queen ;)
