I don't think I could even do that. One thing I loathe more than anything are common sparrows, the ones polluting barns and parking lots. EVERY YEAR they swarm to our bluebird houses and take over! I try to shoot them, but they've gotten smart. Already, a poor sweet blue bird was killed in one of our house, plucked by the evil sparrows. This has happened twice now. They kill bluebirds and take over their nests, which makes me so angry. So I will wait till the female sparrow lays eggs, and put a net over the hole, catch her in it, and either whack her against the ground till she's dead or feed her to the cats. Then I will smash the eggs.
