Hummingbird

We have had a hummingbird feeder out for a few months now, but I had never seen any hummingbirds at the feeder. I stopped changing the nectar since I thought nothing was coming, but then the other day I saw a hummingbird! I was afraid the old nectar would make it sick, so I put in new nectar and bought some more. Since then I've seen the hummingbird on at least two separate days. On Saturday we must have seen it like 5 times. It is so tiny and its little tail waggles when it is flying.
