Simple Solar Bird Bath Heater

This is Jim's nice simple solar bird bath heater that keeps the  bird bath water unfrozen during the daytime in cold PA winters.

The finished birdbath with collector panel facing right.

This shows the internal construction -- its a passive thermosyphon solar collector that circulates the solar heated air across the bottom of the metal bird bath container.
