ABSTRACT:
A tubular plastic bird feeder is made from a unitary blow molded enclosure which includes engageable thread patterns on one end cap and the adjacent end of the tubular body which are separated in molding by an integral annular sleeve. The sleeve is cut away circumferentially at both ends from the as-molded enclosure leaving a separated end cap which may be threaded onto the end of the tubular body. Similar integrally molded thread patterns may be formed on the lower end of the unitary enclosure to provide either a removable lower end cap or the facility to thread another tubular body onto the lower end of the first tubular body to provide an extended length feeder. The preferred embodiment also includes a circular barrier disc supported in the tubular body below the lowermost seed holes to prevent seed, and other particles from accumulating in the inaccessible lower end of the feeder. In lieu of conventional seed holes cut, punched or otherwise formed in the tubular body, the body may be formed in the blow molding process to include angled seed ports with protective deflector hoods.
