I have 2 heated dog water bowls for all the birds that come to my yard every day, one in the front yard and one in the back yard.
It gets in the minuses, but these water bowls keep the water at 50 degrees so there is always fresh water every day this way for all the many beautiful birds. I refresh it every day.
What a wonderful idea. Thank you Mary for taking the trouble to get in touch.
They are something I have never heard of. I will have to see if I can find any. A Christmas present to myself!
Can I ask where you live?
Thanks and also have a Lovely Christmas
