The mallard is the most common of the wild ducks. Males are easily recognized by their shiny green heads, a white ring around the neck, and curled black tail feathers. Females, on the other hand, have brown-toned plumage with subtle patterns that help them blend into their surroundings. Mallards are social animals, often seen swimming in groups in lakes, rivers, and wetlands.
