How to Make Holes Smaller in a Bird House
- 1). Measure and mark your wood to make a square shape large enough to extend 1 inch past the present birdhouse hole in all directions.
- 2). Cut out the square shape with a handsaw.
- 3). Measure and mark a hole in the center of the wood square large enough for desired birds, but small enough to exclude invasive birds. Bluebirds and swallows need 1 1/2-inch-diameter holes, while chickadees need 1 1/8-inch-diameter holes. Check the chart on the Amish Gourds website to see the required hole sizes for other birds.
- 4). Cut out the hole with a keyhole saw.
- 5). Sand all rough edges on the wood. If desired, paint it to match your birdhouse. Let the wood dry completely before attaching it to the birdhouse.
- 6). Wash the area around the birdhouse hole with soap and water and let it dry.
- 7). Position your wood square over the current birdhouse hole so the new hole covers the old hole. Mark the placement with a pencil.
- 8). Glue the wood square to the birdhouse with wood glue.
