Bombshelling!

I caught the impending battle between two hummers over the right to drink from the feeder this morning.  The one diving in had actually been drinking at the feeder when I was standing at the camera preparing to start shooting.  Then the one in the rear flew in and "scared" it away. 

It apparently didn't take too kindly to its meal being interrupted so abruptly.  It immediately swished around, and as you see here, when on the attack full throttle.  Several seconds later, it was perched once more to complete its meal in peace. 

When it was done, the losing, but originally aggressive hummer (which I now discovered to be none other than...Zippy!), returned and got a drink without interruption. Should have guessed it was him to pick the fight!
