The Wood Duck, (Aix sponsa,) was designated South Carolina official State Duck by Act Number 58 of 2009. The Wood Duck is often considered the most beautiful duck in North America due to its striking coloring. The Wood Duck is a medium size duck ranging from 17 to 20 inches and weighing 1.5 pounds. Their feet are webbed but also have sharp claws to allow for perching on trees. They tend to habitat in woodland ponds, lakes, swamps and marshes feeding on the vegetation and insects.
The wood duck or Carolina duck (Aix sponsa) is a species of perching duck found in North America. It is one of the most colorful North American waterfowl. Males are iridescent chestnut and green, with ornate patterns on nearly every feather; the elegant females have a distinctive profile and delicate white pattern around the eye. These birds live in wooded swamps, where they nest in holes in trees or in nest boxes put up around lake margins.
The Wood Ducks or Carolina Ducks are small to medium sized birds. Both male and female adults have a crest on their head, a rectangular shaped tail, white bellies and white lines on the back of the wings. Males are 48 to 54 cm long, while females are 47 to 51 cm long. Their wingspans are 70 to 73 cm long and they weigh between 500 and 700 g. The sexes are dimorphic. The males' heads are iridescent green, blue and purple and have two white lines that are parallel and run from the base of the bill and behind the eye to the back of the head. Male wood ducks also have red eyes, red at the base of the bill, rust-colored chests, bronze sides and black backs and tails. The females are brownish to gray and have white eye rings, white throats and gray chests. Juvenile wood ducks resemble adult females. Wood ducks are sometimes mistaken for American widgeons (Anas americana) when flying because the white lines that wood ducks have at the back of their wings are not visible. Also female wood ducks are mistaken for female Mandarin ducks (Aix galericulata). The difference lies in the Mandarin duck's lighter gray head and less distinctive eye patch.
The average lifespan of A. sponsa is three or four years. The maximum recorded lifespan in the wild is roughly 15 years. Within the first two weeks after hatching 86 to 90% of the chicks die. One cause of mortality is predation. Hunting also accounts for some mortality, however, hunting pressures are not enough to endanger the species.
