Insect infiltration protection apparatus for pole mounted bird feeder

An insect infiltration protection apparatus for a bird feeder comprising a reservoir and a bushing, the reservoir having an outer rim and an inner rim with a dish-shaped body extending between the outer and inner rims, the dish-shaped body having a bottom surface with the outer rim and the inner rim projecting from the bottom surface, the inner rim projecting from the bottom surface at a greater distance than the outer rim such that the inner rim is vertically above the peripheral edge of the outer rim, the reservoir having a support surface defining a central through hole adjacent the inner rim, the bushing being made of a resilient material, the bushing having an exterior with a taper and a central aperture, the resilient material of the bushing extending continuously around the central aperture and extending continuously radially outward from the central aperture to the exterior taper to form a solid bushing, the central aperture of the bushing being adapted and configured for an interference, friction fit with a pole such that the central aperture expands and biases the bushing against the pole and is sufficient to permit the bushing to support the reservoir on a pole at a height above a pole supporting base by which the pole is supported with a liquid retained in the reservoir at a liquid level below the inner rim and at a level equal to or below the outer rim of the reservoir, the support surface of the reservoir having an interior with a taper, the taper of the interior of the support surface of the reservoir matching the taper of the exterior of the bushing, the taper of the interior of the support surface extending from a flat portion of the support surface adjacent to the inner rim, wherein when the reservoir is assembled with the bushing and the reservoir and the bushing are mounted on a pole, the taper of the exterior of the bushing frictionally engages with the taper of the interior of the support surface of the reservoir to support the reservoir on the bushing with a space between the bushing and the flat portion of the interior of the support surface and with the bottom surface of the dish-shaped body below a peripheral edge of the outer rim with the dish-shaped body retaining a liquid at a liquid level below the inner rim and at or below the outer rim of the reservoir.
