My solution to this was to add hot water (just off the boil for making coffee) to the birdbath on truly cold (10-25 F) mornings. If you truly get a lot of strong winter sunlight on freezing winter mornings, the solar heater could work - but check our local climate data for of cloud-free sub-freezing days before you invest too much effort.

If you're really want it to be heated you could do it caveman style, fire. If you can rig a low heat fire to a NONFLAMMABLE bird bath and kept it from over heating of exploding, I suppose it's possible.

Paint the bottom of the bowl black to absorb more sunlight. As lemonie says, you could use a pump, and you could supplement the power for it from the mains when there is not enough from the solar source.
