ABSTRACT:
A bird feeder (10) for all seasons having a seed reservoir (12) for gravitationally delivering food in pellet or seed form to an inner bell (20) positioned within an outer bell (22). The inner bell (20) and the outer bell (22) rotatably mate with each other and are shaped to provide a closed mode for storage and an open mode for food access. In the open mode the outer bell (22) is rotated so that arch apertures (44) in the inner bell (20) align with inverted arch apertures (66) in the outer bell (22). In the closed mode the arch apertures (44) of the inner bell (20) align with the outer cylindrical wall (54) of the outer bell (22). A damper (24) controls seed flow, and a cover structure (18) with a sloping roof (74) retains the inner bell (20) and outer bell (22) in a rotatable position relative to each other.
