This thermostatically controlled all-season birdbath with built-in perch costs only pennies a day to operate. Its large 1.5 gallon capacity means filling less often. With its hidden electrical connection, simply plug your extension cord into the built-in connection on the bottom side of the unit. The basin easily removes from the “twist-on” deck mount for convenience and cleaning. An optional matching pedestal, model Ped II, is also available. Three year limited warranty.
