In reply to Crow Lady:
Hi Marina -have you had a look at the Bernini fountains? They are not solar powered but run on a rechargeable battery pack (40 hrs per charge). I personally didn't like the solar one I bought (my garden is quite shaded so they may work better in sunnier gardens). I recently bought a Bernini one-they are not sold as bird baths but the birds drink from it and are slowly starting to use it for bathing- they are good quality and have a remote control. I bought mine through QVC, but here's their official website
