A height adjustable bird feeder apparatus which allows for the selective lowering and raising of a bird feeder relative to a stationary, vertically oriented pole, wherein the apparatus includes a pole, a sleeve concentrically mounted to the pole so as to be slidable therealong, an article, preferably a bird feeder, mounted to the sleeve, and a sleeve retention mechanism. The sleeve extends entirely through the bird feeder at the center of gravity. The sleeve retention mechanism has a plurality of sets of diametrically opposed holes formed in the pole which receive therethrough a removable pin. An optional critter guard is located at the bottom of the sleeve. When the feed becomes depleted, the user removes the pin and lets the sleeve slid down the pole to the bottom. At this height, the bird feeder feed reservoir is now easily replenished. After filling, the user lifts the bird feeder and sleeve combination back up the pole and reinserts the pin.
