Abstract: A birdfeeder which operates with a perch that is controlled by the use of magnetic force that allows certain smaller birds to freely feed while inhibiting larger birds and small animals, such as squirrels, from feeding is provided. The birdfeeder has a plurality of movable pivoted perches which move from a first position to a second position. In the first (horizontal) position, a small bird may sit on the movable perch and reach an opening in a food hopper while the weight of a larger bird or animal will force the movable perch downward into the second (non-horizontal) position wherein the perch is moved away from the opening in the food hopper. A magnet located on an end of the movable perch secures the perch in the first position until the weight of a larger bird or animal causes the movable perch to pivot to the non-horizontal position.
