Ruby Throated Hummingbird
I was photographing some tulips, in front of one of our hummingbird feeders, when a pair of hummers got a bit territorial with each other. They were flying all around me, chittering like crazy, whilst asserting their dominance over one another as to who "owned" the feeder. I guess the female won, because she is the one who settled down to feed just a few feet from me. FUN!
