Ducks "Flying"

I live by the water and we have a lot of beautiful, graceful water fowl.  Most notably the amazing  Canadian Geese (who live here year round it appears), the Western Grebe, the Cormorants,  and even the Seagulls.  And then we also have the Ducks.

The Ducks are usually migratory and think it's perfectly fine to plop down in the middle of a busy parking lot for a nice rest.  They seem so puzzled when one of us humans gets out of the car to shoo them over to the side.  But what I love about the Ducks the most is just how distinctive their flying "style" is.  You can spot a Duck even in low light because of it.  Their wings are flapping very fast and the body language is almost as if they're shouting OMG Look!  I'm Flying!  Wow.  FlapFlapFlapFlap.

How they manage to migrate anywhere is just a little amazing to me as they appear to be the definition of using entirely too much energy to fly.  Maybe we have to shoo them out of the parking lot because they really are that tired.
