I claim: 1. A squirrel resistant bird feeder comprising: a seed container; a seed tray mounted below said seed container; a shroud enclosing said seed container and said seed tray in an open and closed position; at least one feed opening in a lower portion of said shroud; a cover member extending over said shroud and being non-removably secured thereto; a central tube extending between said seed tray to an upper portion of said seed container; a center post within said central tube, said center post having a first end secured to said seed tray, said center post having a second end extending through said cover member; and a spring member mounted about said center post within said central tube, a first end of said spring member biasing said seed tray, a second end of said spring member being arranged such that said shroud is biased to said open position when said at least one feed opening in said shroud permits access to said seed tray, said shroud being moveable to said closed position when a weight on said shroud compresses said spring member, said closed position denying access to said seed tray. 2. The bird feeder of claim 1 further including at least one perch attached to said shroud, said at least one perch being situated below said feed opening. 3. The bird feeder of claim 1 further including a hanger secured to said second end of said center post, said hanger preventing removal of said cover and shroud. 4. The bird feeder of claim 1 wherein said cover member and said shroud are formed as a single piece. 5. The bird feeder of claim 1 including a plurality of perches attached to said shroud below said feed opening, said perches being pivotably mounted thereto whereby said perches pivot upwardly. 6. The bird feeder of claim 4 further including a negative grip tube extending about said hanger exteriorly of said cover member, said negative grip tube being freely moveable along said hanger. 7. The bird feeder of claim 1 wherein said shroud has an open bottom. 8. The bird feeder of claim 1 wherein said seed container is designed to distribute seeds therefrom onto said seed tray. 9. The bird feeder of claim 1 wherein said seed container, said central tube and said central post comprise a non moveable structure, said shroud and cover member being moveable with respect thereto. 10. The bird feeder of claim 1 further including first and second stop members, said first and second stop members limiting movement of said shroud movement between said open and closed positions. 11. A squirrel resistant bird feeder comprising: a seed container; a seed tray mounted below said seed container; a shroud extending about said seed container and said seed tray; at least one feed opening in a lower portion of said shroud; a cover member extending over said shroud and being non-removably secured thereto; a central tube extending between said seed tray to an upper portion of said seed container; a center post within said central tube, said center post having a first end secured to said seed tray, said center post having a second end extending through said cover member; and a spring member mounted about said center post within said central tube, a first end of said spring member biasing said seed tray, a second end of said spring member being arranged such that said shroud is biased to an open position when said at least one feed opening in said shroud permits access to said seed tray, said shroud being moveable to a closed position when a weight on said shroud compresses said spring member, said closed position denying access to said seed tray; and a plunger, said plunger being mounted within said central tube, said plunger having a lower end forming a socket to receive said second end of said spring, a second end of said plunger abutting said cover. 12. The bird feeder of claim 11 further including a compressible sealing member extending about said center tube and said plunger. 13. A squirrel resistant bird feeder comprising: a seed container; a seed tray mounted below said seed container; a shroud extending about said seed container and said seed tray; at least one feed opening in a lower portion of said shroud; a cover member extending over said shroud and being non-removably secured thereto; a central tube extending between said seed tray to an upper portion of said seed container; a center post within said central tube, said center post having a first end secured to said seed tray, said center post having a second end extending through said cover member; a spring member mounted about said center post within said central tube, a first end of said spring member biasing said seed tray, a second end of said spring member being arranged such that said shroud is biased to an open position when said at least one feed opening in said shroud permits access to said seed tray, said shroud being moveable to a closed position when a weight on said shroud compresses said spring member, said closed position denying access to said seed tray; a hanger secured to said second end of said center post, said hanger preventing removal of said cover and shroud; and a compressible sealing member extending about an upper end of said central tube. 14. The bird feeder of claim 13 wherein said compressible sealing member has an accordion-like structure.
