Going back to August when we were camping in Roosevelt National Forest, Colorado. We had put out our hummingbird feeders and were enjoying watching the little birds come by and grab a drink. This one though seemed to think the feeders belonged to it and it alone. It would perch in the nearby bushes and the second another hummingbird approached it would chase it off. Lots of fun to watch but with as fast as they move, not easy to keep up with.
