The wood duck (aka “woodie”) is a bit odd compared to other puddle ducks. For starters, they’re cavity nesters. While a few diving duck species are cavity nesters—hooded mergansers, goldeneyes and buffleheads—the only other puddle duck that is, is the black-bellied whistling duck. Overall, though, it’s rare among most ducks.
The woodie’s propensity for cavity nesting is partly why its numbers are solid across most of its range. Nesting off the ground helps wood ducks elude predators, like foxes, raccoons, skunks, opossums and crows, that plague other species. The flooded brush environments woodies favor also provide lots of overhead cover, which protects them—especially younger birds—from avian predators, like hawks, owls and eagles.
Conservation efforts have helped, too. Nesting boxes, built and placed by hunting/conservation organizations, civic groups, youth camps and…
