These guys don't pack heat... yet! They still handle things with beaks and body slams al la WWF. I tried equipping one with a pylon mounted 17 Remington Fireball; we still haven't found the bird. The bullet fell and the bird went backwards at 4000 fps; back to the drawing boards.
I love watching them do that. I still dont get why I only seem to have one or two hummers this year. I saw the male yesterday in the flower beds. He went to the feeder as well, but then was gone and not seen again. Odd.
