Water is a vital resource to birds in the winter. Offer fresh water to birds and squirrels through the winter months with a heated pan. Long-lasting Western Red Cedar frame and post. The post is hollow so the 12 inch electric cord, and fully-grounded outdoor extension cord -not included, can be placed out of sight. Assembly required. Comes with two hold-down stakes to secure feet to the ground. Guaranteed to provide your birds with water down to -10 degrees F or -23 C. The insulated 60-watt heating element is thermostatically-controlled, enclosed and sealed inside the pan, and activated when water temperature goes below 35 degrees. Removeable, 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.
