An easy to assemble mechanical apparatus and methods that create a barrier for deterring birds from landing at or near undesirable perching locations. The barrier is created by a rotating carriage that is propelled in a rotational motion by the wind or an available draft of air. A first embodiment utilizes a rotatable carriage which is an assemblage of individual parts that form one unified rotating body which rotates on antifriction bearing surfaces with horizontally disposed rods extending radially outward therefrom. A second embodiment utilizes a pivot pin which supports the rotating carriage portion and is designed to be placed in a variety of locations by an easy-to-use locknut and groove system. A quick action push-nut, or other means for securing, secures the rods or means for creating a barrier onto the carriage. The carriage rotates about the pivot pin with a multiplicity of rods or a means for creating a barrier extending out to any desired length and at any angular disposition from the carriage.

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.

A picnic table mounts a plurality of support members at each end thereof extending orthogonally relative to the top surface of the table. The support members include a plurality of spaced parallel rods, with each rod including a series of equally spaced parallel and coextensive ribbons extending downwardly therefrom, wherein the ribbon flexible construction effects prevailing winds to effect a fluttering of the ribbons and thereby discourage flying insects about the table.

A fishing pole holder is pivotally mounted on the upper end portion of an upright tubular housing to rock upwardly and downwardly about a horizontal axis. A battery-operated motor is contained in the housing and is operable to rotate a cam having a plurality of angularly spaced lobes which act against a cam follower on the holder to rock the latter upwardly and downwardly. With this arrangement, a fishing pole supported in the holder may be automatically moved upwardly and downwardly in order to jig a lure in the water.
