Birdbath : No one likes to get splashed

We have a new birdbath. It's really more like a birdpool. I had fears it was too deep when I bought it, but went ahead with it. The only birds that actually bathe in it have been robins and thrashers. The rest (finches mostly) just seem to take a drink from the edge or from the rock I put in. Today a robin was taking a nice splashy bath when a titmouse landed on the edge in between splashes. The next three photos show that even birds don't like to get splashed when they are just sitting on the side of the pool. :) birdbath100 web Turning my face away from the splash birdbath101web Can you see who took flight? birdbath102 web
