The young male hummers are feeling their 'wheaties', so to speak. The fighting or play fighting has begun. I have a feeder at my kitchen window and my breakfast was served with a live play of sword fighting, bump and run, and plenty of tiny screams!
I ventured out just to make sure the other feeder was full (it was) so I found a hiding spot nearby to try to catch a few shots.
Near the kitchen window is a flower garden. I caught this young male resting between bouts on the climbing rose.
