Last year I bought a fancy bird bath.
That was stupid. I knew as the sale's clerk was ringing the purchase up, that no bird in its right mind was gonna use the bird bath I was buying. For one thing it was deep. It was sort of two level, with a deeper part in the center. To make matters worse, it was plated in a slick blue coating. I can't imagine a bird with sense is going to walk around on some slick surface, and risk breaking those tiny legs.
