The Aix sponsa or Wood Duck is a species of perching duck found in North America. The drake wood duck is one of the most colorful North American waterfowls.

The adult male has stunning multicolored iridescent plumage and red eyes, with a distinctive white flare down the neck.

The female, less colorful, has a white eye-ring and a whitish throat. Both adults have crested heads. The speculum is iridescent blue-green with a white border on the trailing edge.

The population of the Aix sponsa or Wood duck was in serious decline in the late 19th century as a result of severe habitat loss and market hunting for both meat and plumage for the ladies’ hat market in Europe.

By the beginning of the 20th century, Aix sponsa or Wood ducks had become rare, almost disappearing in many areas.

In response to the Migratory Bird Treaty, established in 1916, and enactment of the U.S. Migratory Bird Treaty Act of 1918, wood ducks finally began to repopulate.

By enforcing existing hunting regulations and protecting woodland and marsh habitats, wood duck populations began to rebound starting in the 1920s.

The erection of nesting boxes starting in the 1930s further assisted Aix sponsa or the Wood duck conservation. Providing artificial nesting sites for wildfowl, including wood ducks, is beneficial.

Wood duck boxes have been found to be less effective than natural, hollow, dead trees but remain overall beneficial for the population.
