Next on our list of ugly birds is the muscovy duck (Cairina moschata) – one of the oldest domesticated fowls in the world.
Native to North and South America, these large black and white ducks can reach around 30 inches in length and weigh about 15 pounds.
Males of this species are almost double the size of females. These birds are considered ugly due to the lumpy reddish skin or wattles on their faces.
Muscovy ducks are usually found near grasslands, streams, or freshwater swamps with plenty of food. Their diet consists of a variety of plant matter, insects, fish, amphibians, worms, and so on.
