Robins, doves, finches, sparrows; an occasional woodpecker, cardinal, or blue jay. Lately I'm aware of one big brute of a crow that I wish would decide to fly south. In a typical week we fill one trash bag just a little too full to slip it down in the garbage can for trash day. If I set the bag out with any lead time at all, the sonovagun rips any number of holes in it.
