Trying to keep birds off my spreaders in hopes of keeping my deck cleaner. I’ve seen other boats that have strung what looks like 0.020″ safety wire a couple inches above the spreader from mast to shroud.
Does this work?
How would you attach it to the mast? My thought is an 8-32 monel screw at the mast with the head drilled for the wire and just wrapping it around the shroud.

Birds don’t like things above them, attach a flag to your main halyard and run it up above your spreaders
Don’t drill a lot of holes in masts or spreaders. These are highly loaded structures. Holes weaken them, especially if they are not perfectly round (a twist drill makes a triangular shape) and not completely filled by a fastener (like a solid rivet).
If you need to install spikes or wires, use an adhesive
