A lone Hummingbird fends off a flock of frenzied flyers

This little Hummingbird is creating quite a stir in our backyard -- he has decided that the nectar is all his.  My wife, Linda, went and bought a second feeder.  Our flying defender then decided both  feeders were his and chased any other fellows of the feather away when ever they ventured near.  

I decided to move the two feeders further apart to see if that would get his generous juices flowing. It did not work.  It just made him have to work harder -- defending a larger perimeter.  In this photo after fending off an frenzied attack by a squadron of feathery flyers, he ruffles his feathers.  I am not sure if he is trying to enlarge his stature or just trying to refresh himself for the next assault on his flavory fluid.
