What you need:
- Clean plastic one- or two-liter soda bottle with cap
- Masking tape
- Plastic lid (lightweight, such as those from a margarine tub; diameter should be larger than bottle bottom)
- Knife (such as an X-Acto knife; for adult use only)
What to do:
- Prepare the bottle by cutting out two triangles. First punch three holes, in the shape of a triangle (about 1/2 inch apart), around the shoulder of the bottle. Use a knife to transform the holes into small triangles. (This should be done only by an adult!) This is where the seed will come out.
- Cover the triangular cutouts with masking tape. This will keep the birdseed from falling out until you put up the feeder.
- Punch two holes a quarter inch above the bottom of the bottle, on opposite sides. Thread a piece of string, about 20 inches long, through the two holes. Knot the ends.
- Trace around the cap of the bottle on the center of the lid. Cut out the outline to make a hole in the lid.
- Push the neck of the bottle through the opening in the lid. Make sure it is a snug fit.
- Screw the bottle cap on tightly. Use a funnel to pour birdseed into the bottle. While you're making the bird feeder, discuss how they help birds. (They help birds survive the winter, when there is less food.)
- When you hang the bird feeder outside, look for branches that will not be readily accessible to squirrels. Hang up the feeder and remove the masking tape.
- Observe the feeders often. You may even want to keep a written record of your observations.
