What is claimed is: 1. A bird feeder, comprising: a food container including one or more feeding ports configured to allow birds access into said food container; and a separate perch located relative to each feeding port to enable a bird perched thereon to access a respective feeding port, each of the separate perches being elongated and rotationally mounted at one end to move in a radial direction with respect to a longitudinal axis of said food container so as to have an adjustable distance from a respective feeding port. 2. The bird feeder of claim 1, wherein each elongated perch has a varying height in relation to its respective feeding port to accommodate different sized birds relative to its respective feeding port. 3. The bird feeder of claim 1, wherein each elongated perch is curved in said radial direction of rotational movement with respect to said longitudinal axis of said food container. 4. The bird feeder of claim 1, wherein each separate perch is rotationally mounted to a rotatable member located within said food container and configured to extend substantially radially through a separate respective opening in said food container to be located in front of a respective feeding port. 5. The bird feeder of claim 4, wherein said rotatable member is configured to be rotated relative to said food container to determine a relative position between each said perch and said food container in proximity to a said respective feeding port. 6. The bird feeder of claim 5, wherein a relative position for each perch is determined by a relative rotational position of said rotatable member with respect to said food container and resulting interference between each perch and said food container at said respective opening. 7. The bird feeder of claim 6, wherein said food container includes a bottom member rotationally coupled to said food container and linked to said rotatable member to enable rotation of said rotatable member by rotation of said bottom member. 8. The bird feeder of claim 7, wherein said food container has a generally cylindrical shape and wherein said bottom member is circular. 9. The bird feeder of claim 8, wherein said food container includes a first circular cross-sectional portion having a first plurality of said one or more feeding ports located therein. 10. The bird feeder of claim 9, wherein said food container includes a second circular cross sectional portion that has a second plurality of feeding ports, and further comprising a separate respective perch located relative to each feeding port of said second plurality of feeding ports to enable a bird perched thereon to access a respective feeding port, wherein each separate respective perch is elongated and rotationally mounted at one end to move in said radial direction with respect to said longitudinal axis of said food container to have an adjustable distance from a respective feeding port. 11. The bird feeder of claim 10, further comprising a second rotatable member rotationally mounting said separate respective perches located relative to respective feeding ports of said second plurality of feeding ports, wherein said second rotatable member is configured to be rotated relative to said food container to determine a relative position between each said separate respective perch and said food container in proximity to a said respective feeding port of said second plurality of feeding ports. 12. The bird feeder of claim 11, wherein said second rotatable member is linked to said bottom member so as to enable rotation of said second rotatable member. 13. The bird feeder of claim 12, further comprising first and second cylindrical collars respectively located around said first and second circular cross-sectional portions and configured to allow access to said first and second plurality of feeding ports, respectively, by rotation of said first and second cylindrical collars around said first and second circular cross-sectional portions and relative to said food container. 14. The bird feeder of claim 13, wherein said first and second plurality of feeding ports each includes relatively smaller and larger openings configured to allow selective use of smaller and larger sized bird feed, respectively, and wherein said first and second cylindrical collars allow selective access to said smaller or larger openings by rotation thereof relative to said food container. 15. A bird feeder, comprising: a food container including one or more feeding ports configured to allow birds access into said food container, said food container having a substantially vertical orientation; and an adjustable perch located relative to each of the feeding ports that enables a bird perched thereon to access a respective feeding port, each of the perches being elongated and rotationally mounted at one end to move in a radial direction with respect to a longitudinal axis of said food container and being curved in said radial direction of rotational movement with respect to said food container so as to be radially positionable relative to the respective feeding port. 16. The bird feeder according to claim 15, wherein each of said perches includes a first perch section adjacent the rotationally mounted end having a first perch height, and a second perch section at an end opposite to the rotationally mounted end having a second perch height that is lower relative to the first perch height. 17. The bird feeder according to claim 15, wherein each of said perches is rotationally mounted to a rotatable member located within said food container, and said rotatable member is configured to rotate relative to said food container to provide the adjustable perch position. 18. A bird feeder, comprising: a food container including one or more feeding ports configured to allow birds access into said food container, said food container having a generally cylindrical shape and a substantially vertical axial orientation; and an adjustable perch located relative to each of the feeding ports that enables a bird perched thereon to access a respective feeding port, each of the separate perches being elongated and rotationally mounted at one end to move outward and inward in a radial direction with respect to a longitudinal axis of said food container to provide an adjustable perch distance from a respective feeding port for accommodating different sized birds. 19. The bird feeder according to claim 18, further comprising a first and a second circular cross-sectional portion each having respectively a first and a second plurality of said feeding ports located therein, and a first and a second cylindrical collar respectively located around said first and second circular cross-sectional portions that are configured to allow access to said first and second plurality of feeding ports, respectively, by rotation of said first and second cylindrical collars around said first and second circular cross-sectional portions. 20. The bird feeder according to claim 19, wherein said first and second plurality of feeding ports each includes relatively smaller and larger openings configured to enable selective use of smaller and larger sized bird feed, respectively, and wherein said first and second cylindrical collars enable selective access to said smaller or larger openings by rotation thereof relative to said food container.
