cuckoo clue

A clue to a letterbox that travels from letterbox to letterbox, usually within a small area near the location of the cuckoo clue letterbox. When you find a cuckoo clue, you should take it with you and deposit it in another nearby letterbox (or copy it down and leave it in the original letterbox). Cuckoo clues are not published on the Web, and should not be publicly discussed. See also bonus box.
