Keep water available for your birds year round with the Farm Innovators All Seasons Decorative Bird Bath with Deck Mount. The 18" diameter and 2.25" depth is perfect for any size bird, and the color mimics concrete and blends with any outdoor décor. A heating element hides between two layers of sturdy plastic, and is thermostatically controlled to only operate when the temperature nears or drops below freezing. A plug on the bottom of the bath connects to any properly grounded outdoor extension cord, and a grommet through the deck mount allows the cord access to the plug. The deck mount connects to any railing from 2.75" to 6" wide with the included thumb screws. Uses 120 Watts. 3-year manufacturer's warranty.
