The piano, which weighs at least 650 pounds, was placed at the highest spot along the sandbar so it doesn't get underwater during high tide.
While officials aren't sure how it got there, they know it won't be going anywhere unless it becomes a hazard to wildlife or boaters.
Florida Fish and Wildlife Conservation Commission spokesman Jorge Pino says the agency is not responsible for moving such items. And, he adds, unless it becomes a navigational hazard, the U.S. Coast Guard won't get involved.
For now, the piano has become a fancy roost for seagulls.
