  • Patent number: 6986322
    Abstract: A bird feeder for preventing squirrels and other type rodent animals from consuming the bird food includes a top convex surface, a bottom convex surface and a concave middle surface. The top and bottom convex surfaces are inverted bowls having equal diameters and depths. The concave middle surface is a non-inverted bowl having a diameter less than the top and bottom inverted bowls, and has a greater depth. The middle bowl holds the bird food for birds to consume. The rim of the middle bowl may serve as a perch for the feeding birds to light upon. The top and bottom inverted bowls serve as protective shields that prevent rodent animals, such as squirrels from reaching the middle bowl. These shields are constructed from a substantially rigid material, having a substantially smooth surface. The smooth surface and the convex shape prevent squirrels or the like from establishing a foothold so that they may consume the bird food.
