Birdie Battles

Yesterday afternoon Kathy watched the two chicks leave the nest.
The Female followed after them and that was that... they were gone.
This morning 4 or more Males are scuffling about who is to be in the bird house next.  
Two of these birds had a knock-down, drag-out battle on our front porch.
Gosh, the birdie drama involved with our bird house is taxing on us!
