Almost four hours later, to the minute, and I just saw my first hummingbird. I'm so excited. I was afraid I would only get bees and ants.
UPDATE: WhooHoo. There were two guys fighting over it this morning. Now I'm really excited. Looks like all that work to get the silly thing up is going to be worth it. I'm loving how the feeder looks from the street too. It reminds me of those little water powered rockets we used to play with as kids.
