While pleasing to the human race, this isn't too practical for the hummingbirds. I wondered why they didn't come back when I changed out my plastic red one with this one. I researched it and they really do love their brightly colored red one. So, I tested it. I put both of them back up, filled with fresh food and waited. Over the next few days, the hummingbirds came back, but they spent most of their time on the red plastic one and only occasionally dipped their beak into this one. So, this one now resides in my garage, packed away.
