We lost Jim's very nice passive solar bird bath for a while, but is back now.
The passive solar bath provides some unfrozen water in the winter for the birds to drink. Its a nice simple design that is easy to build and has worked well for Jim.
Thanks very much to Jim for documenting this project!
The solar collector on the bottom heats the drinking dish on the top.
If you have any ideas for improvements or any questions, or have a design of your own that you would like to report on -- please use the Comments section on this page...
