Oxyura jamaicensis
Most duck species have one or two characteristics that make them different. But with ruddy ducks, almost everything is unusual. Although abundant in summer, few people get a glimpse of them. Ruddy ducks are shy, spending much of their time surrounded by the cattails that grow in shallow water at the edge of wetlands.
