Abstract
A bird perch formed of a bendable, tightly wound wire formed in a generally hollow cylinder. A first end of the perch is adapted for replaceable mounting in a bird feeder opening, and the body of the perch adapted to downwardly bend when a large, that is, heavy, bird attempts to rest thereon and remain generally straight to support small, that is, light, birds resting thereon. The individual wire windings are closely spaced or touching to prevent the birds' feet from being caught in the spaces therebetween.
