Abstract
A bird perch assembly formed of a bendable tightly wound wire perch formed in the shape of a generally hollow cylinder and further provided with a keeper device such that its potential for lateral elongation is prevented or diminished. Such perch assembly is adapted for replaceable mounting in a wild bird feeder opening such that the perch downwardly bends when a large, that is, a heavy, bird attempts to rest thereon and remains generally straight to support a small, that is, a light, bird resting thereon.
