ABSTRACT:
A device that prevents birds from landing atop a masthead of a boat or wind indicating devices mounted on the masthead includes an upstanding post having an upper end positioned above the top of the mast and any wind indicating devices. A plurality of rods radiate outwardly from the upper end in interfering relation to the landing area atop the masthead or wind indicating devices to foil landing attempts. The post is attached to a halyard and the device is raised in an inverted configuration when the halyard is raised. The device is also attached to a downhaul line so that when the device reaches the top of the mast, pulling on the downhaul line inverts the device and deploys it into its operative configuration. The radially disposed rods positioned in the landing area deprive birds of the clearance space they need when landing.
