Mast Head Cactus

Eliminate birds from roosting at the mast head by installing some mast head cactus. Commercial products are available at the hardware store but the handy can construct their own by threading seizing wire through a cork coaster and then twist the spikes into a supporting structure. Glue into place with a blob of silicone. The hardest part will be installing. For that a trip up the mast by the skilled will be needed.
