Claim:
A birdbath comprising: a base including an input to receive water and a conduit operatively coupled to the input to receive water through the input; a bowl including a circumference, the bowl coupled to the base; a barrier attached to a surface of the bowl so as to be centered within a mass of water to be held by the bowl; and a first nozzle mounted on the circumference of the bowl and operatively coupled to the conduit to receive water and provide a first stream; wherein: the first nozzle is operative during a cleaning phase to stream water at a first pressure such that water is sprayed into the bowl of the birdbath with sufficient force to cause water to swirl around the barrier, wherein the swirling water cleans the bowl and debris and contaminated water in the bowl are discharged when such debris and contaminated water cross in line with the water stream from the first nozzle, the cleaning phase operating for a pre-determined cleaning time, and the first nozzle is operative during a filling phase to stream water at a second pressure, which is lower than the first pressure, such that water is sprayed from the nozzle to fill the birdbath bowl with water for a pre-determined fill time.
