This type fo bird feeder can be made from a plastic recycled drink bottle and a plastic lid or food container. Any size drink bottle can be use as most of them have a one inch bottle cap. Note, squirrels will eat the bottle to get to the food.
Step 1: Drill One Inch Hole
Using a one inch wood drill bit like the one shown here with the two small cutting edges, drill a one inch hole in your lid or food container. With a little practice you can make a nice clean hole.
Step 2: Melt Holes in Bottle
Using a small soldering iron, melt about eight 3/8 in holes near the top of the bottle. These holes are for the seed to feed out of the bottle. Melting the holes seems to work much better than trying to drill them. Melting leaves a somoother hole than a drilled one.
Step 3: Install Wire or String Hanger
Melt a very small hole in the bottom of the bottle and pass a wire through the hole and out the top of the bottle. Bend a small loop in the wire to keep it from pulling back through. Put a large loop on the other end of the wire to hang the feeder.
