Recycled Bottle Bird Feeder
A plastic water bottle becomes a bird feeder in about 20 minutes, and the transformation demonstrates the power of reuse more concretely than any lecture could. Children help drill the perch holes, fill the bottle with birdseed, and hang it outside — then watch as birds discover it over the following days. The feeder is genuinely functional and lasts for an entire season.
What You'll Need
- A clean plastic water bottle or juice bottle — 16 oz works well
- Two wooden pencils or thin dowels — for the perch
- Birdseed — wild bird blend
- Twine or wire — for hanging
- A nail or drill — for making holes (adult task)
- Optional: craft paint — to decorate the bottle before filling
How to Do It
Step 1: Make the perch holes. Using a nail or drill, poke two holes through the bottle on opposite sides, about 2 inches from the bottom. Make them just large enough for a pencil to slide through. Repeat 2 inches higher and rotated 90 degrees for a second perch.
Step 2: Make the seed holes. Just above each perch position, poke a small hole (about the diameter of a pencil tip) — these are where seed flows out as birds eat.
Step 3: Insert the perches. Slide a wooden pencil through each pair of holes so it extends a few inches on each side. Birds land on the perch and reach up to eat.
Step 4: Fill with seed. Remove the cap, fill the bottle with birdseed, and replace the cap firmly.
Step 5: Attach the hanger. Wrap twine around the neck of the bottle just below the cap, tie securely, and make a long loop for hanging.
Step 6: Hang and observe. Choose a spot visible from a window, about 5 feet from the ground. Keep a pair of binoculars nearby for close-up viewing.
Skills Your Child Will Develop
Recycling and reuse — Transforming waste into a useful object is the most concrete introduction to sustainability.
Engineering thinking — Designing a functional feeder involves problem-solving and testing.
Nature connection — Observing birds daily builds ongoing curiosity about the natural world.
Tips & Variations
- Paint the bottle with weatherproof craft paint for a more decorative look.
- Make one feeder per child to take home as an Earth Day project.
- Keep a bird identification guide nearby and record which species visit.
My Two Cents
Check the seed level every 3–4 days — a feeder that runs empty stops attracting birds. Children are excellent at monitoring the seed level if you make it their responsibility.
