Another use of the birdbath warmer: I wire one underneath the flat bottom
of the red part of my 1 quart hummingbird feeder which is hung near enough
to the house all year round to have access to electricity. It works great
and then I just remove the wires and heater during warmer times. Bob

P. S. Perhaps this has been mentioned before but if a hummingbird feeder
starts freezing it's pure water that freezes and the remaining liquid
becomes more and more concentrated in sugar. There is a potential if
there's just a little bit of liquid left that the solution would be
damaging to hummingbirds.
