ABSTRACT:
A bird feeder having a metal feed container located inside a concentric, coaxial, metal shroud cover that rotates. The metal prevents the feeder from being chewed into by undesirable animals, as well as prevents the birds from seeing the feed in the feeder, therefore the birds curiosity keeps them coming to the feeder to cause its rotation, therefore aiding in the rotation of the feeder cover to cause the feeder to cycle its open to feed mode to its closed no feed mode, allowing the feeder to feed intermittently, as the feeding windows of the cover become misaligned and back to alignment in their relationship to the orifices of the feed container, a cycling of the feed, no feed modes is attained. When the feeder is in its no feed mode, no animals can access the feed in the feeder, including the birds themselves, this is approximately one half of the time of a complete cycle. When the feeder is in its open to feed portion of the cycle which is approximately the other half of the time of a complete cycle, it will feed all birds large and small that are commonly fed at feeders. Should a squirrel or any animal as heavy as a squirrel or heavier attempt to feed, the cover shroud will move downward over the feed container, blocking access to the feed container. Type and size of feed to be fed, can attained with the seed selector band, by its location of placement on the feed container.
