Thanks for the review on solar pumps. I had also read that they don't work very well. I did try a battery powered 'wriggler' in my birdbath. Can't recommend that either. It worked, but I couldn't keep it out of the water. I'm not always home when a sudden thunderstorm might dump lots of rain and raise the level in the birdbath. Guess I'll just keep wanting for now. Will possibly look into how much running a line might cost, because I think you get a lot more bird activity when you have moving water.
