I have an Owl family that shows up each year due to my fountain, a large tree for sleeping, and access to preserve.  Though small, the old fountain was tough to keep filled, so upgraded to a larger one that I could set up an autofill on.  This new one is the perfect size, but I removed the top piece after a Raven knocked it over.   Only issue is the plug to seal the power cord hole didn't fully seal, so had to use some silicone on the back side to plug it.
