Hi, I've been reading everyone all summer and feel like an eavesdropper, but have really enjoyed all the conversation. Lots of learning. Because of this I've changed my feeders to the Humzingers. I don't know if I picked up more birds, but I see more at the same time! There seems to be a ton of them right now and they are really busy. Anyway, last week I went to a hummingbird festival and the Audubon Society was banding birds. It was a great thing to watch and participate in. There was a cage around the feeder where the bird was caught. It was then banded, measured and if you'd made a donation you had that bird "assigned," (for lack of a better word) to you and then you released it. I heard one man had a letter that his bird had been to Costa Rica! Don't they get around!
