At my previous course we had a wily crow, only the one, who would hang around the 10th green. Perfect spot, people usually get a snack out after 9 holes and munch as they walk. Reach the green, a par 3, put their snack on their bag and whoosh, away he would go with a claw full ?. Plenty of members would take spare and throw it for him/her but visitors were frequently caught out. That bird was definitely part of the club ?. You have to admire their daring.
