Do male Rufous chase male Anna's? Female Rufous female Anna's? Maybe the Rufous is territorial there, and the Anna's are "floaters."
I didn't realize Anna's were so common at Gig Harbor. 3 Anna's at a feeder at once is rather unusual for this area, I thought.
>> Reply The three times I witnessed this behavior, there were two female Anna's at the feeder. I am not a hummingbird identification expert, but the birds looke d closest to the female Anna's (including the "dot" on the throat). One male rufous would buzz in fast and fan his tail (presumably to stop himself) and then quickly chase the two females off the feeder. He never used the feeder himself. I would guess that at least some of the Anna's are floaters.
I have noticed that this is not an area of dense hummingbird populations in general, however the area in Cromwell that I live in is rich with vines and flowers. It may also be possible that there are relatively few feeders in the area.
One thing is for sure. After watching the junco's, towhees, chickadees for the last few months, its really nice to have the little hummers zooming around. One flew right up to my face and hovered for a second out in the yard. I think I was in his way. Scared the wits out of me for a moment!
