Interested but I wonder how does the water stay cool if I live where the outside temperature gets over 100 degrees during the summer?
Just put a bag of ice in the bird bath, about once every 5 minutes. That should keep the water cool for the birds. 
It doesn’t just like any other birdbath. At least this one gets some air cooling.
Maybe you can just go throw some ice cubes in it I guess if your birds want a cool bath not sure what you normally do
Bought one of these little suckers last year as a joke for my friends pool. Kind of pathetic but loved it. Its still going with the cutest littlist struggle of spraying up the water a year later. Would pay the 9 bucks but not the 20 it usually goes for. Solar powered. Unfortunately I 'm tired of downloading apps to get this deal
If the birds in your area are not penguins, they should be okay
