ABSTRACT:
An improved bird feeder utilizing a sectional roof assembly with an elastomeric material joining a fixed roof section to a second movable roof section. The elastomeric material serves as both an environmental seal and as a hinge to allow easy access to the seed storage area. A flow rate block intermediate the base and a movable wall of the feeder allows bird seed to flow from the interior of the feeder at a rate dependent on the position of the flow rate block.
