3. The Hanging Bottle Spinner Feeder
This clever design turns a squirrel’s weight against itself. When a squirrel jumps onto the feeder, the entire structure spins, forcing the squirrel to lose grip and drop harmlessly to the ground.
Why It Works
Birds are lightweight and can perch without triggering the rotation. Squirrels, however, activate the spinning motion, making it impossible to maintain balance or access seed.
Materials Needed
- Large plastic soda bottle or detergent bottle
- Strong cord or chain
- Hanging feeder
- Drill or utility knife
How to Build
Cut off the bottom of the bottle and drill holes in the top for threading rope. Hang the bottle upside down over the feeder, with the feeder suspended below it. The bottle should rotate freely on the hanging line.
Best Placement
Hang from tree branches or hooks at least eight feet off the ground and well away from nearby surfaces.
Advantages
- Extremely low-cost
- Fun to watch
- Easy to repair or replace
- Lightweight and weather-resistant
This is a great beginner project and works especially well in wooded areas where squirrels frequently drop from branches.
