Hummer Attack! Duck!!

And the battle for the food is ON!!!

I caught a good one of what appears to be an attack of one female (Anna's?) on another of the same  species.  I was watching for the Rufous from yesterday to stir up trouble...but these are definitely not  Rufous hummingbirds.  It's kind of weird to see that two birds that are so alike can't get along at one feeder.  Perhaps I'll put out a second feeder as a social experiment to see if two birds will come at the same time.   That should be interesting...
