Creating nesting boxes for waterfowl is a simple yet effective way to support the conservation of these important species, especially as natural habitats face pressures from urbanization, climate change, and habitat degradation. Nesting boxes provide safe, protected spaces for waterfowl to build their nests and raise their young, helping to increase their chances of survival. This guide will walk you through everything you need to know about building effective nesting boxes for waterfowl, from the materials to use to proper placement and maintenance.
Nesting Boxes for Waterfowl
Waterfowl, including ducks, geese, and swans, rely on safe and secure nesting sites for breeding. These birds typically nest in natural tree cavities, tree hollows, or on the ground near water, but suitable locations can be hard to find due to habitat loss and competition for space. Nesting boxes mimic natural cavities and offer waterfowl a secure environment to lay eggs and rear their young, particularly in areas where natural sites are limited. By building and placing nesting boxes, you can help support waterfowl populations and contribute to the protection of these important species.
Key Benefits of Wood Duck Nest Boxes for Waterfowl:
-
Provide Safe, Secure Nesting Sites: Nesting boxes protect eggs and young waterfowl from predators and harsh environmental conditions.
-
Support Breeding Efforts: By increasing the number of available nesting sites, including nest boxes, you can help boost waterfowl reproduction rates, particularly in areas with limited natural cavities.
-
Enhance Habitat Availability: In regions where wetlands and natural nesting sites are disappearing, nest boxes can provide a critical alternative for waterfowl looking for safe places to breed.
Choosing the Right Nesting Box Design
When building a nest box for waterfowl, the design and dimensions are important factors to consider. Different species of waterfowl, including ducks and geese, have specific needs and preferences for nesting. Below are some guidelines for building the ideal nesting box.
1. Size and Dimensions
-
For Ducks (Mallards, Wood Ducks, etc.):
-
Entrance Hole: A circular hole about 3–4 inches in diameter is typically suitable for most species, including wood ducks. When constructing a wood duck box, ensure the hole size is large enough for the adult bird to enter and exit but small enough to prevent predators from accessing the nest.
-
Box Size: A typical waterfowl nesting box is around 12–16 inches wide, 12–16 inches deep, and 16–24 inches tall. Proper dimensions are crucial for a successful wood duck nest, providing enough space for the birds to comfortably lay their eggs and raise their young.
-
For Geese:
-
Entrance Hole: A larger entrance hole, approximately 5–6 inches in diameter, is necessary for species like Canada geese.
-
Box Size: A larger box may be needed, about 18–24 inches wide, 18–24 inches deep, and 24–30 inches tall, to accommodate the larger size of geese and their nesting habits.
2. Materials
-
Wood: The most common material for nesting boxes is wood, as it mimics the natural environments where waterfowl tend to nest. Use untreated, natural wood like cedar or pine to build the box, as it is durable, breathable, and safe for wildlife.
-
Avoid Pressure-Treated Wood: Do not use pressure-treated wood or treated lumber, as the chemicals used in its treatment can be harmful to birds and other wildlife.
-
Roofing: Use plywood or a similar material for the roof to provide shade and shelter. The roof should extend beyond the edges of the box to keep rainwater from entering.
-
Wood Shavings: Incorporate four to six inches of wood shavings into the bottom of the nesting box. This provides insulation and a safe environment for the ducklings. Remember to replace old shavings during annual maintenance to ensure a clean and inviting nesting site.
3. Ventilation and Drainage
-
Ventilation: Adequate ventilation is essential to prevent the nesting box from becoming too hot and stuffy, particularly during the warmer months. Small holes or slats along the sides of the box will provide airflow without allowing predators to enter.
-
Drainage: Ensure there are drainage holes at the bottom of the box to prevent water from collecting inside. This will keep the nesting site dry and help prevent mold or mildew from forming, which could harm the eggs or young waterfowl.

Step 1: Cut the Wood
-
Sides: Cut two pieces of wood for the sides of the nesting box, each about 12–16 inches wide and 16–24 inches tall, depending on the size of the box.
-
Front and Back: Cut a piece of wood for the front and another for the back, each about 12–16 inches wide and 16–24 inches tall.
-
Bottom: Cut a piece for the bottom of the box, approximately 12–16 inches wide and 12–16 inches deep.
-
Roof: Cut a piece for the roof that is larger than the top of the box to provide coverage, about 16–20 inches wide and 16–20 inches deep.
Step 2: Assemble the Box
-
Attach the Sides: Attach the two side pieces to the front and back pieces using screws or nails, ensuring that they are aligned properly and secure.
-
Install the Bottom: Attach the bottom piece to the sides, front, and back of the box. You can secure it with screws or nails as well.
-
Add the Roof: Attach the roof to the top of the nesting box using hinges on one side. This will allow you to easily open the roof for cleaning purposes later.
Step 3: Add the Entrance Hole
-
Drill the Hole: Use a drill to create an entrance hole on the front of the box, approximately 3–4 inches in diameter for ducks or 5–6 inches for geese. The hole should be positioned about 2–3 inches from the top of the box.
-
Smooth the Edges: Sand the edges of the entrance hole to smooth out any rough spots that could harm the birds.
