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 other end of the unitary enclosure to provide either another removable end cap or the facility to thread another tubular body onto the end of the first tubular body to provide an extended length feeder. One embodiment includes a circular barrier disc supported in the tubular body below the lowermost seed holes to pre- vent seed, and other particles from accumulating in the inaccessible lower end of the feeder. In lieu of conven- tional 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. Another embodiment includes internal and external thread patterns on one end of the tubular body to accommodate either of two seed tray constructions.
