With the Allied Four Seasons Heated Bird Bath the birds get ice-free water all winter long. The 70-watt heating element is completely enclosed within the bird bath and is fully tested at below zero conditions. This bird bath comes with EZ-Tilt mounting hardware for easy cleaning and storage. Mounts to 2"x 4" or 2"x 6" rails, or on the included 36" stand. The 14 inch diameter and 2 inch deep bath has a contoured edge to fit the average talon and encourages birds to land. The gradual slope of the bath and textured surface both encourage bathing. Great for year around use and will not crack in the winter.
