ABSTRACT:
An apparatus for preventing birds from perching utilizes a rectangular flat plate suspended by a rod inserted lengthwise through the plate or two rods inserted into opposite sides of the plate. The rod or rods are intentionally inserted along a horizontal axis which is not the center of the plate, so that the plate rotates eccentrically around that axis. Thus, although the plate rotates freely around the axis, the plate will rest with a smaller section above the axis and a larger section beneath the axis, unless it is disturbed. If a bird attempts to land on the plate, the added weight will swing the plate around the axis, throwing the bird off the plate and preventing the bird from perching. This device is particularly useful when mounted around the perimeter of a birdfeeder, forcing the bird to fly over the anti-perching device and feed from a location around a seed tray inside the feeder. A residue tray can then be located under the seed tray, extending outward to cover the area beneath the seed tray and its perimeter, to collect any offal falling as birds feed.
