发明名称 BIRD FEEDER
摘要 A bird feeder is disclosed wherein a plurality of spaced-apart metal mesh tubes extend upwardly from a tray to a bird seed reservoir. In one embodiment, the tubes are curved much like a barrel stave. In another embodiment, the tubes are elongated and straight cylinders. In another embodiment, the tubes are helical in shape. The tubes are spaced sufficiently apart to enable birds to pass therebetween so that the birds may gain access to the feed in the tubes from all sides of the tubes.
