Leaves, Pool Vacuum and Ducks?

I looked out the window this morning because I saw something in the pool. At first, I thought it was just a toy that landed in the water. When I took a closer look, I noticed there was a duck swimming around. I grabbed my camera to take a picture and discovered there wasn't one duck, but two ducks in our pool.

I contemplated feeding them, but as much as I love wild life and animals, I wasn't too fond of their "surprises" they left for me at the bottom of the pool.

What does that mean? The ducks will have to find another home. Fortunately for me, they flew off the moment I got near the pool. They sure are beautiful to look at though.
