Recycle a standard 2ltr plastic bottle into a wild bird feeder with the original soda bottle bird feeder. Simply fill a clean, empty 2Ltr bottle with birdseed, screw on the feeder adapter and hang with included wire to create an effective and economical bird feeder. Much more robust than the flimsy plastic copies on the market, the cast zinc soda bottle bird feeder is dishwasher-safe. Can also be pole-mounted. A great way to demonstrate the principles of reuse/recycling!
