Wow, that is SO awesome!!!! I'll quit complaining about constantly refilling the feeders for the five or so we have around here all summer!! Thanks for taking care of our travel-weary buddies! In case you haven't tried this, there's a magazine called "Birds and Blooms", and they have a website; not sure of the address, but you can google it. They have a Q & A thing in their magazine for readers, and I think they may also have a forum on their website for questions like yours; you might be able to find an answer there as to where to get a big feeder like the one you describe. I bet they'd love to have a copy of your pics for their magazine, too! What a story!
