We had bluebirds here when we arrived 25 years ago, and someone had positioned bird houses for them. But our cats were too naughty. So we took down the bird houses and encouraged the bluebirds to nest elsewhere. We still see them once in a while, though.
I just planted some squash, cucumbers, and flowers in "pony-packs" and put them in our wimpy greenhouse. It's better than nothing. I guess I ought to post about it....
