发明名称 Bird feeder
摘要 A bird feeder which utilizes the common necked container such as a plastic soda or soft drink bottle as the feed storage container, with its screw neck downward, attached to a conduit, hood and cup assembly and a perch extending around the cup. The container holds an ample supply of feed, which flows by gravity through a conduit to refill the cup as birds remove the feed. A hanging device on the container bottom provides an attachment point for the hanging up the feeder.
