We also enjoy our birdbath and it is only a flower pot bottom. We keep it filled year round. Even with ice in it, the sparrows will still take a cold bath. We had so many birds such as robins, cardinals, bluejays, mocking birds, sparrows of all kinds, dark eyed junkos, warblers, flickers, starlings, grackles, turtle neck doves, morning doves, goldfinches and even hawks. We have taken pictures of all these birds and I am sure I have left out a few. Then we made a video called Backyard Birdbath. At one time we had to put rocks in it before the smaller birds would get into it but now they are used to it and climb on it. There is only room for 1 or 2 robins so they stand in line waiting to take their baths. We love watching the variety of birds this has brought to our home.
