McGyver's friends

McGyver has been making friends. They are pigeons, and they sit outside on the neighbor's roof in the morning. We are trying to dissuade him from fostering friendships with the likes of them, however. They aren't the best influence on him, as they eat garbage and crap everywhere. But it is good for him to develop some social skills, so until the more charming birds come back from their southern winter vacations we will have to see the best in his pigeon friends.
