Great stuff, I'm currently observing the air war going on around my feeder, I now have 3 of the little buggers trying to gain superiority over the others to get primary feeding rites. I think two of them may be related as they tolerate each other and will actually share the feeder, but as soon as the third shows up it's every hummer for him(her)self.
