ABSTRACT:
A weight sensitive squirrel proof bird feeder with multiple perch rods. In general, a feed reservoir includes perch rods positioned generally perpendicular to an outer surface of the feed reservoir. When a predetermined weight is placed upon the perches, the perches rotate about their longitudinal axis by a motor thereby expelling the source of the weight, typically squirrels or other undesirable animals from the perches.
