I came across a small flea market in a church parking lot and saw some really interesting bird feeders made of glass ware - plates and bowls - and colorfully painted chick feeders to dispense the seed from a Mason Jar. I asked the couple if I could take pictures, and they were agreeable. We joked about how the fellow drills the plates. bowls and jars inside a cardboard box to make the clean up easier if the piece being drilled broke in the process. He says he uses a diamond hollow point bit in case you're interested. I have some lovely old glassware, but this is not my field of expertise.
On the way back through the park I saw lots of ducks on the banks of Orange Lake and lots of kids playing in the play structure built maybe 12 or 15 years ago by volunteers.
