Redhead Aythya americana
(cheesy ass super long link because I'm at work and thus too lazy to figure out how to html it...)
*edit*
OK, so cheesy ass super long link because I'm at work and thus too lazy to figure out how to html it was forking up my friends page so I'm guessing it might do the same to some of yours so you'll have to google search the bird yourselves to see what it looks like. It's basically a duck. With a red head. Shocking, I know.
/ *edit*
But he flew off before I had a chance to get a picture. So besides the everyday Mallards & Canada Flying Vermin that we always have, that's 4 other kinds of ducks I've seen this year...
