Water is an important resource to birds year around. Offer fresh water to birds and squirrels through the winter months with a heated pan. Made of beautiful red cedar and designed to keep water thawed down to -20, this top-of-the-line wooden birdbath is well made and makes an attractive addition to any bird watcher's yard. In winter birds will flock to fresh water, and this Heated Cedar Birdbath has exactly what they need. The insulated 60-watt heating element is thermostatically-controlled, enclosed and sealed inside the pan. Activated when water temperature goes below 35 degrees, the movable, heavy-duty, forest-green, bird bath pan is 14 inches diameter, 1 inch deep. It holds .5 gallons of water that stays thawed, but does not get warm.
