Is it art? A prank? A new kind of nest for birds? squirrels? racoons? "It" is a traffic cone, but there's not much traffic up there except the aforementioned wildlife. The gardners must know it's there so perhaps they're conspirators. It will be all but invisible when the trees leaf out. It's at least 30 feet off the ground, so it'll take some work (or a fat racoon) to bring it down.
