Five, no six. And I just bid on and got a beautiful small glass one with inlaid butterflies at a Church auction. Most are plastic. One is on the ground and I just loved it. It had tile in the bottom and the design was two goldfish. For some reason a swellling started in the bottom, pushing the tiles off :o(
My immediate thought was a garden with two or more birdbaths in the bed. But I love the plants you selected to surround yours.
The robins and sparrows actually prefer the one on the ground.
