Claims12
A bird feeder comprising:
- a reservoir inducing an upper section with a central opening therein and a closure means for closing said central opening and an open-ended lower section;
- an external food dispensing tray capable of maintaining a frictional fit within said open lower section of said reservoir, wherein said food dispensing tray further includes an upwardly extending central section having an annular base portion with a shoulder, a tapered annular mid portion with a plurality of grippers, and a conical-shaped upper portion;
- wherein said food dispensing tray includes a generally flat closed bottom having a diameter greater than that of said reservoir and an upwardly extending outer annular wall;
- and
- wherein said plurality of grippers comprise a series of annular ridges and valleys located about said tapered annular mid portion of said upwardly extending central section and wherein said grippers enable said friction fit between said tapered annular mid portion and said open-ended lower section of said reservoir.
