ABSTRACT:
A bird feeder of cylindrical shape is hung by a loop on the top of a wire which runs through the center of the full length of the feeder. A beveled upper edge on the bottom closure, and spring perches, and no other protruding parts along the full length of the feeder prevent squirrels from securing a position on the feeder. There are no moving parts, and all parts are highly weather resistant.
