Whether you decide to build your own or purchase a duck boxes help address habitat loss for cavity-nesting duck species.
Nic Bray, a wildlife biologist for the Georgia Department of Natural Resources, said duck boxes offer a home to a variety of wildlife species.
“The boxes allow for less predation due to the design of the box itself,» said Bray. «It’s primarily for wood ducks, but black-bellied whistling ducks, screech owls will also use them, too.”
A wood duck box is a man-made, weather-resistant nesting box designed to provide a safe, elevated nesting cavity for wood ducks and other cavity-nesting birds, according to the Georgia Department of Natural Resources.
These boxes are crucial for conservation, offering a secure alternative to natural tree cavities in wetlands, rivers, and ponds. They typically feature a 4-inch hole, with wood shavings for nesting.
Natural tree cavities are scarce due to urbanization, according to the South Carolina Department of Natural Resources Wildlife Division. Duck boxes provide an alternative for breeding and raising young. Proper, maintained boxes boost local wood duck populations, aiding in the species’ ongoing conservation.
What you need to know about duck boxes
Duck boxes should face open water when possible. Ideal placement should be within 200 feet of water.
Drainage holes in the floor help to prevent flooding. Vent holes near the top to reduce heat buildup.
Hardware cloth or rough scoring below the entrance helps ducklings climb out.
Duck boxes should be mounted on poles with predator guards.
Building the wrong structure in the wrong habitat often leads to empty boxes.
Untreated cedar, cypress, or rough‑cut pine resists rot and provides grip for ducklings climbing out.
Built duck boxes offer an added layer of protection from predators like racoons and rat snakes to cavity nesting duck populations.

Built boxes offer an added layer of protection to cavity-nesting duck populations, said Bray.
“A rat snake or a raccoon could enter a nesting cavity utilized by a wood duck,” said Bray. “Those are known predators that will (prey) on eggs, especially the rat snakes. And the ducks don’t really have a defense against it. The boxes are constructed on a post with a cone that goes on the bottom called a predator cone.”
The predator cone can prevent a snake from climbing up the wood post, said Bray.
