Homemade Wooden Bird Feeders

Lay the piece of exterior plywood that measures 18 inches by 18 inches by 1/2 inch on the working surface --- this will serve as the base of the tray.

Drill a 3/8-inch drain hole at each of the four corners of the base. According to Cornell University, lack of drainage could lead to seeds sprouting or bacteria and fungi developing in the tray.

Tack the window screen over the base, covering every drain hole to prevent seeds from falling.

Hold each of the four quarter-round dowels against one side of the base. Lay every dowel so that one flat side is flush with the edge of the floor and the convex side faces outwards. Secure with waterproof wood glue or galvanized nails.

Turn the tray upside down and attach a floor flange on the center of the bottom surface of the tray. A floor flange has a flat, circular shape with a large hole in the center and several smaller holes around the center hole. Drill the bolts that come with the floor flange through the smaller holes to keep it in place.

Place one end of the metal pipe in the middle hole of the floor flange and the other end in the ground. The length of the metal depends on your preference and the type of birds you want to attract. According to Cornell University, various birds like different feeding heights.
