I'm clueless again. The glass is about 5 1/2" long with a 1" opening at bottom(bad 2nd pic of neck isn't chipped but mold marks, glass swirls & bubbles).
What is it? TIA Katrinka
It's part of a humminmgbird feeder; I have one like yours in red that I bought a few years ago. I don't remember how it worked - or rather how it didn't - but I hang the glass piece as an attraction next to my other feeders.
That makes sense. Just need a stopper with a red tube through it. Now I know what to look for. THANKS BUNCHES!
