Carolina Duck Negative Footprint or Wood Duck measures 2.95 x 2.24 inches. The wood duck  is a medium-sized perching duck.

Carolina 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 Carolina Duck 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.

Landowners as well as park and refuge managers can encourage wood ducks by building wood duck nest boxes near lakes, ponds, and streams.

The population of the wood duck has increased a great deal in the last several years. The increase has been due to the work of many people constructing wood duck boxes and conserving vital habitat for the wood ducks to breed.

During the open waterfowl season, U.S. hunters have been allowed to take only two wood ducks per day in the Atlantic and Mississippi Flyways. The 2008–2009 season, the limit was raised to three.

The wood duck limit remains at two in the Central Flyway and at seven in the Pacific Flyway. It is the second most commonly hunted duck in North America, after the mallard.
