Mallard and mottled ducks are two distinct species of waterfowl with several key differences. Mallards, belonging to the genus Anas, are a familiar sight in North America and Europe, recognized by their distinctive green heads and brown bodies. Mottled ducks, on the other hand, are found in the southeastern United States and are characterized by their mottled brown plumage.
Size and weight are other distinguishing factors. Mallards are typically larger than mottled ducks, with males weighing an average of 2.2 pounds compared to the latter’s 1.5 pounds. Female mallards are also larger than female mottled ducks, weighing an average of 1.5 pounds compared to 1.1 pounds.
