ABSTRACT:
A tube-shaped bird feeder with a tiltable perch which allows a person to control the maximum weight of a bird which can feed on the feeder by adjusting the counterweight attached to a tiltable perch. When a heavier bird alights on the perch, the perch swings down out of the way without closing the feeding openings. Once the bird flies away, the perch swings back into a feeding position so a lighter bird can alight and eat the seeds. In one embodiment a shield screens the birds view of the feeding opening. The feeders can be mounted individually or can be gang mounted on a post stand to permit multiple birds to eat at the feeder. A float located inside the feeder alerts an owner to the need to replenish the feeder.
