A bird feeder preferably includes a top lid, a central housing pivotally coupled to the top lid, a bottom base pivotally coupled to the central, and a mechanism for automatically articulating a first one of the top lid and the bottom base along a first arcuate path while manually articulating a second one of the top lid and the bottom base along a second arcuate path. In this manner, the central housing remains at a statically fixed position while the top lid and the bottom base articulate between corresponding open and closed positions. In one embodiment, the articulating mechanism may include an actuating shaft contiguously abutted against a gear for ensuring the bottom base simultaneously rotates with the top lid during opening and closing positions respectively.
