I'm liking your cardinals much better than the pair that is pecking on my dining room windows for 5 days! That pair seem to think that the house plants that are near the windows are great nesting spots and won't give it up. We've covered the plants, put a plastic snake on the covering, now I have tea towels taped over the lower part of the window and the plastic snake is on the deck chair outside the windows. I hope they give up and build a nest somewhere before they need it for eggs!
