Clean the inside of a coffee can using soap and water. Turn the can upside down and let it dry overnight.
Drill two 1/8-inch holes into the side of the coffee can. Place the first hole 1 inch from the bottom edge of the can and the second, parallel from the first, 1 inch from the top of the can. Twist an eye hook into each of the holes.
Feed a 12-inch piece of twine through each of the eye hooks. Use the twine to hang the feeder from a tree branch.
Use a utility knife to cut a 2-inch hole into the lid for the coffee can. Place the hole 2 inches from the edge of the lid. Punch a hole underneath the 2-inch hole using a hole puncher.
Insert a 1/4-by-3 inch dowel rod through the punched hole. Place 1 inch of the dowel rod inside the lid and the other 2 inches outside to create a perch for the feeder.
Fill the can with birdseed and place the lid on the coffee can with the hole and perch on the opposite side of the can from the eye hook.
Tie a 12-inch piece of string around a pine cone, positioning the string 1 inch from the bottom.
Cover the pine cone in peanut butter.
Roll the peanut butter covered pine cone in birdseed.
Hang the pine cone from a tree using the string.
Clean an empty plastic milk jug using soap and water. Let the jug dry overnight. Once dry, place the lid back on the jug.
Cut a 3-inch hole in the side of the milk jug using a utility knife, positioning it 2 inches up from the bottom of the jug.
Fill the bottom of the jug with birdseed and place the completed feeder on a fence post or outside deck from which the birds can feed.
