What are you doing to deter birds
I know this has been discussed in the past, but you never now what new inventions might have been developed by sailors to keep birds off the boat.
I taped a pinwheel to a stick and hauled it up the main halyard so it ended up just above the mast top. It seemed to work, but it didn't last long. One of the blades broke off and that was all she wrote. What are others doing to keep birds of the mast, particularly big birds like osprey?
