We have one that hangs upside down to steal seeds from the bird feeder . He is about a crazy bastard , the feeder has a steel wire that it hangs on and he wraps his feet around the wire , then lowers himself down to the seed . The best time is when he gets the feeder spinning at high rpms , enough to dizzy him up and falls off ! He sure is a crazy bastard ! I wish I knew how to upload vids of his escapades .
