摘要:
A U-shaped perch for a bird feeder which is selectively movable between retracted and extended positions with respect to the bird feeder. The perch is horizontally slidably mounted in a support at the lower end of a feed port positioned in a feed opening formed in the bird feeder. The perch is selectively locked in its extended position. The perch and the support cooperate to limit the outward extension of the perch with respect to the support. The perch may also be movably mounted on the bird feeder which does not have a feed port.
