I echo what others have said lately about how well fountains draw birds.
My design is basically the same as what Steve showed yesterday, though with
one considerable imperfection: There's no easy way to change the water.
That's what I'd do differently now that I've had this one for several years
and every time I need to change the water it's a hassle. So that's my
design tip - think through a way to make that easy.

Good fountaining to ya.
