For years, we've been using a heater in our birdbath during the cold months. This year, I'm using a babbling brook water wiggler along with the heater during the cold nights. We've been using the original water wiggler since it 'came out' for the warm/hot days.
When we had to replace our water wiggler this Spring, we decided to spend a little more and get the babbling brook water wiggler and it's worth every penny! We've seen more birds, more different birds and birds that never used the birdbath come to birdbath!
We always get our heater at Duncraft, but the one we got there isn't available for sale, but if we had to replace it this Winter, the link below is for the one we'd replace it for.
