Abstract

A birdbath is disclosed that recirculates water and includes a substantially hollow pedestal that supports a basin. The pedestal forms a water reservoir therein and has an open top end and a sealed bottom end. The basin has an inner wall and an outer wall, both of which are joined at least at a peripheral edge of the basin and separated by a distance sufficient to allow the water to flow therebetween. The outer wall is open at a central portion and is adapted for engaging the open top end of the pedestal for attaching the basin thereto. The inner wall has an aperture formed therethrough at a center portion thereof, and at least one drainage aperture formed proximate the peripheral edge of the basin. A water pump is disposed within the reservoir of the pedestal for pumping water from the reservoir through a basin supply conduit, through the aperture of the inner wall, and into the basin. Once the water reaches the at least one drainage aperture, it drains between the inner and outer walls, and flows through the central portion of the outer wall and back into the reservoir.
