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.

The present invention provides a bird feeder apparatus for providing a readily available supply of feed for birds. The apparatus comprises a telescopic-operational assemblage, a shroud assembly, and a hopper assembly. The telescopic-operational assemblage provides a nonlinear, geometrically-based closure mechanism for effectively closing the bird feeder when a large load is placed upon the shroud assembly such as when a squirrel attempts to gain access to feed outlets of the hopper assembly by positioning itself upon the apparatus. Further, the apparatus provides a partitioned, selectively removable (drop out-type) hopper for enabling easy refills; a feed-level status flag assembly for indicating to the user whether the hopper assembly is full or empty; and at least one surround perch assembly for accommodating birds of various sizes.

The invention provides a user-configurable perch for a bird feeder. The perch comprises four generally “U”-shaped or “C”-shaped lobes arranged in a generally circular loop, where the loop provides the surface onto which the birds perch. The loop is coupled to a central plate by four support members, which serve to separate the center plate from the loop. The perch is coupled to the bird feeder with a fastener inserted through a hole in the center plate. The perch may be coupled to a bird feeder in one of two configurations. In a first configuration, the loop is positioned below the bottom surface of the bird feeder to accommodate larger birds. In a second configuration, the loop is positioned, above the bottom surface of the bird feeder to discourage larger birds and cater to smaller birds.

The invention relates to a feed additive premix for low-salinity cultured marine fishes.
