We used to have SO many hummers when I lived in Utah. They were all different colors, and so pretty!
For about 5 yrs we had a hummer nest just outside the front door. It was on a ledge on our wrought iron railing. There would be a couple tiny little eggs every spring, with the new babies eventually flying off on their own. Some one told me it's unusual for them to nest in the same spot, but like I said, it was every yr for about 5, then they just left
But we used to have probs with hornets as well. Though I never did figure out how to keep them away!
