These are wonderful, easy to use additions to making a personal bird feeder. I have used these in my classroom for two years and completely enjoy the ease of using them.
What a neat way to recycle old soda bottles! I like this idea better than just cutting holes in the bottles. It looks nicer and the seeds have less chance of getting wet or spilled. Just be careful to place it away from where squirrels will try to get to the seed. They may chew away the plastic to get to the seed.
