发明名称 Bird feeder
摘要 The bird feeder is unique and yet extremely practical. It is comprised of a length of pliable plastic tubing permanently sealed at one end and open at the other end to provide a cylindrical container for receiving and retaining bird seed. After the seed has been placed in the container the throat or top end is closed by means of a length of nylon cord, wire, tape or the like. The other end of the cord is used to suspend the bird feeder from a tree branch or other securement protrusion. A perch bar or bars are provided for said container. One end of each bar or stick is pointed. The pointed end is used to pierce opposite sidewalls of the plastic container and permit installation in any desired horizontal position with opposite ends protruding to provide two perch stations upon which birds may alight. Depending on the size of bird which is to be attracted to the feeder, a second hole is pierced a desired distance above the perch station to enable a bird to extract a seed at a time for consumption. Because the feeding hole was pierced, no other seed will spill from the container nor will the seeds be affected during inclement weather.
