Shucks!
I had a feeder a few years ago and bought the expensive sunflower seeds for the cardinals, but the scrappy birds would congregate in swarms causing the shy cardinals to back away. I want to teach them karate, but they don't understand sign language. The mess under the feeder was not very attractive either, so that project died pretty quick. Nectar feeding seems clean in comparison.
Me and the robins had a tug-o-war for a few weeks while they tried to build a nest under my back porch metal awning. I had at least eight corners barracaded with materials tied to the rafters, and would you believe it tried to nest over the porch light? I have never seen anything so determined to overrule me. You'd think busting the nest several times would let them know that predators were around. Nothing frightens them, I guess.
The next battle is with my new plants. I put in some pansies since frost won't bother them, and these blankety-blank birds pull them right up out of the ground for nesting. How sad that I can't enjoy the flowers yet, for they are all covered with chicken wire. Why bother?
