Aix sponsa, commonly known as the Wood Duck, is native to North America. Its geographical distribution spans from southern Canada through the contiguous United States and parts of northern Mexico.

Wood Ducks predominantly inhabit wooded swamps, freshwater marshes, and shallow streams. They favor areas with abundant aquatic vegetation and tree-lined water bodies. The species is often found in mixed deciduous-coniferous forests near water.

Wood Ducks are cavity-nesting birds, often nesting in tree hollows near water. They are known for their strong claws, which help them grip onto bark and perch on branches. These birds feed on a variety of foods, including seeds, fruits, insects, and other small aquatic animals, reflecting their adaptability to both terrestrial and aquatic environments. Seasonal migrations can lead to variations in precise habitats based on food availability and breeding requirements.
