A bird feeder has a containment housing and a convertible feed port assembly mounted through a housing opening. The feed port assembly includes a feed port having a port plate and a support frame which extends into the housing through the port opening. The port plate defines a port opening aligned with the housing opening to enable access to the bird feed within the housing. The feed port assembly also includes a door slidably and rotatably mounted in the feed port. In a retracted position, the door is supported by the support frame in the housing and leaves the port open to provide access to seed within the interior of the housing. The retracted door cooperates with the support frame to form a roof or baffle to prevent seeds from falling out of the port opening. The door is slidable outwardly from the housing interior and rotatable to overlie and close off the door opening. The door has a relatively small aperture for access to small bird seed when the door is closed.

What is claimed is: 1. A bird feeder comprising: a bird feed containment housing having a housing wall defining a housing interior and having at least one housing opening to receive a convertible feed port assembly; a convertible feed port assembly including, a feed port having a port plate with a port opening therethrough aligned with said housing opening to enable access to bird feed within the housing and engageable with the exterior of said housing wall, and a support frame connected with said port plate and extending through the housing opening into the housing interior, said support frame including a track oriented substantially transverse to said port plate for receiving and supporting a door; and a movable door having a feed aperture therethrough, said door engaged within said track so as convert said bird feeder between an open door position in which said port opening of said port plate is opened by moving said door to a retracted position within said housing interior such that bird feed within the housing is accessible through said port opening, and a closed door position in which said port opening is closed and bird feed within the housing is accessible only through said feed aperture of said door, said door remaining engaged with said track in both said open and closed positions and while moving therebetween. 2. The bird feeder of claim 1, wherein said port plate is contoured to the housing wall and said port opening is coplanar with said port plate, whereby bird feed is retained entirely within said housing and accessible through the port opening. 3. The bird feeder of claim 2, wherein said feed port includes a perch located below said port opening. 4. The bird feeder of claim 2, wherein said feed aperture is substantially smaller than said port opening. 5. The bird feeder of claim 4, wherein said feed aperture is sized for access to thistle feed within said housing. 6. The bird feeder of claim 2, wherein said port opening has top, bottom, and opposite side edges, and said support frame is substantially U-shaped including a pair of parallel side walls interconnected by a back plate, each side wall including a track extending from said port plate to said back plate from adjacent said top edge of said port opening, and said door including a pair of slides for rotating said door on said axis, each of said slides extending from opposite side edges of said door and positioned within said track and slidable thereon such that said door, when retracted, is supported within said housing at a level adjacent the top edge of said port opening. 7. The bird feeder of claim 6, wherein said door, said side walls, and said back plate form a shed to prevent seed from flowing out of the port opening. 8. The bird feeder of claim 6, wherein said slides are rotatable within said track to orient said door to close said port opening. 9. The bird feeder of claim 6, wherein said door includes top, bottom and parallel side edges, and each of said slides includes a pin integral with said door and extending from opposite side edges. 10. The bird feeder of claim 6, further comprising a second convertible feed port assembly identical to said convertible feed port assembly and mounted within a second housing opening aligned with said housing opening, wherein the back plates of each feed port assembly are adjustably interconnected with respect to each other. 11. The bird feeder of claim 1, wherein said door, in its retracted position, provides a baffle to prevent seed from flowing out of the port opening. 12. The bird feeder of claim 1, wherein said port plate includes an inward projection received in a hole in said housing wall to maintain said feed port assembly aligned with said housing opening. 13. A bird feeder comprising: a bird feed containment housing having a housing wall defining a housing interior and having at least two opposed housing openings; a pair of interconnected, back-to-back, convertible feed port assemblies received and supported in said two opposed housing openings; each of said convertible feed port assemblies including, a feed port having a port plate with a port opening therethrough aligned with said housing opening to enable access to bird feed within the housing and engageable with an exterior surface of said housing wall, and having a support frame connected with said port plate and extending through the housing opening into the housing interior, said support frame including a track that extends generally perpendicular to said port plate; and a door having a feed aperture therethrough and being slidable and rotatable in said track so as to move said door between a retracted position generally parallel with said track in which the port opening is open and bird feed within the housing is accessed through the port opening, and a closed position generally perpendicular to said track in which said port opening is closed and bird feed within the housing is accessible only through said door feed aperture, said door remaining engaged with said support frame in both of said positions and while moving the therebetween. 14. The bird feeder of claim 13, wherein said door includes side edges with a slide extending from each of said side edges, each slide being rotatable and slidable within a respective track that extends from the port opening into the housing interior. 15. The bird feeder of claim 13, wherein said track is defined by side walls of said support frame which extend from the port opening into the housing interior, said side walls being interconnected by a back wall. 16. The bird feeder of claim 13, wherein said port plate further includes a perch positioned below said port opening, said port plate being free of any external troughs. 17. A convertible feed port assembly for a bird feeder comprising a feed port plate having a port opening therethrough, a pair of side walls extending from the port plate adjacent said port opening and interconnected by a back wall, each of said side walls including a track generally perpendicular to said port opening, a door mounted to overlie the port opening generally coplanar with the port plate in a first position, said door including side edges with a slide extending from each of said side edges, each slide being rotatable and slidable within said track to enable said door to rotate and slide along said track to a retracted second position that is substantially perpendicular to and adjacent the top of the port opening, said door when fully retracted being supported in a substantially transverse position relative to said port plate. 18. The convertible feed port assembly of claim 17, wherein said door in said retracted position, said side walls and said back wall form a substantially enclosed shed. 19. The bird feeder of claim 17, wherein said port plate further comprises a perch positioned below said port opening, said port plate being free of any external troughs. 20. The convertible feed port assembly of claim 17, wherein said door includes a small feed aperture such that, when said door is in said first position, said port is closed and bird feed within the housing is accessible only through said feed aperture, said door in said second position opening said port opening to allow bird feed to be accessed through said port opening.
