Providing suitable nesting sites for these beautiful birds.


Building a wood duck nest box is a tangible act of conservation, fostering the well-being of a species integral to wetland ecosystems. These nest boxes offer critical nesting sites, mitigating the loss of natural cavities due to habitat changes. Wood ducks, known for their vibrant plumage, faced population declines in the past, but conservation efforts, including nest box programs, have played a pivotal role in their recovery. Constructing nest boxes contributes to habitat restoration, ensuring these stunning birds have secure places to breed and raise their young. It embodies a commitment to preserving biodiversity and fostering a harmonious balance in our shared environment. Here are step-by-step instructions on how to make a wood duck house and place it in the right location:

Materials Needed:

  • Exterior-grade plywood (3/4-inch thick)
  • Cedar or redwood boards (1×6 inches)
  • Wood screws
  • Outdoor wood glue
  • Hinges
  • Waterproof wood sealant or paint
  • Galvanized nails
  • Saw
  • Drill
  • Screwdriver
  • Measuring tape
  • Pencil

Step 1: Design the Nest Box

  1. Use a Proven Design
    • Utilize a proven wood duck nest box design. Dimensions can vary, but a common size is approximately 10 inches by 10 inches for the base and 24 inches tall. (each link shows a different option.)
  2. Entrance Hole
    • Include an oval-shaped entrance hole, approximately 4 inches by 3 inches, situated about 18 inches above the floor.
  3. Sloping Roof
    • Design the roof to slope downward from the entrance hole to prevent rainwater from entering the box.

Step 2: Cut the Wood

  1. Cut Plywood
    • Cut the plywood into the necessary pieces based on your design. You’ll need a front, back, roof, floor, and two sides.
  2. Cut Side Boards
    • Cut the cedar or redwood boards to create two side boards, which will act as the sides of the nest box.

Step 3: Assemble the Box

  1. Assemble the Box
    • Attach the front, back, and sides to the base using wood screws. Use outdoor wood glue for added stability.
  2. Attach the Roof
    • Attach the roof at a slight angle to allow rainwater runoff. Use hinges to secure the roof, allowing for easy access for cleaning.

Step 4: Drill Drainage Holes

  1. Drainage Holes
    • Drill small drainage holes in the floor of the nest box to prevent water buildup.

Step 5: Seal or Paint the Box

  1. Seal or Paint
    • Apply a waterproof wood sealant or outdoor paint to protect the nest box from the elements. Allow it to dry thoroughly.

Step 6: Install the Nest Box

  1. Choose the Right Location:
    • Install the nest box near a body of water, such as a pond or stream, with easy access for the ducks. Place it 10-15 feet above the ground.
  2. Face the Entrance Away from Predators
    • Face the entrance away from prevailing winds and potential predators. Adding a predator guard on the entrance can help deter unwanted visitors.
  3. Mounting the Box
    • Securely mount the box on a post, pole, or tree using galvanized nails. Ensure it is stable and won’t sway in the wind.

Step 7: Monitoring and Maintenance

  1. Monitor the Nest Box
    • Regularly monitor the nest box during the breeding season. Wood ducks may use it for nesting and raising their young.
  2. Clean the Box Annually
    • Clean the nest box annually, preferably in late winter or early spring, to remove old nesting material and ensure it’s ready for the upcoming breeding season.

By following these steps, you can create and install a wood duck house that provides a safe and suitable nesting environment for these birds.
