Abstract: A method and apparatus components for converting a plastic carbonated beverage bottle into a bird feeder. The apparatus components include pointed feeder trays for insertion into the bottle through specially formed slots cut in the sidewall of the bottle, and a decorative sleeve with corresponding cut-outs is secured around the bottle sidewall. An umbrella-like cover made from a flat piece of flexible plastic is clamped atop the bottle by the bottle closure cap of the bottle to protect the seed from rain and to prevent squirrels and the like from taking the bird seed. A piercing-and-cutting tool is provided to pierce the bottle sidewall and sleeve to create the slots for the insertion of the feeder trays and is also useful for making an opening in the bottle cap for the receipt of a support line. A reinforcing cap washer is nested interiorly of the bottle closure cap for added strength and attachment with the support line.
