Why We Like It

This is a really creative way to recycle walnut shells to create an naturalistic puzzle feeder for birds and other small animals. You could scale this up and use coconut shells for larger animals, too.

  • Walnut shells, in half

  • Twine or yarn

  • Clip or carabiner

  • Food to put in the shells

  • Drill with small drill bit

How to Make It
  1. Cut a piece of string about 2 ft long

  2. Tie a knot at one end of the string

  3. Drill holes in the middle of each walnut shell half

  4. String the walnut shells onto the piece of string.

  5. Once all of the shells have been threaded onto the string, tie the end of the string to the carabiner or clip.

  6. Fill each shell with a bit of food. You could include nuts, seeds, veggies, leaves, or fruits.
