Size: 15"

The ruddy duck is a member of the “stiff-tailed ducks,” known for their rigid tail feathers, which are often cocked up in display. It dives deep into the water for its food, which consists of aquatic vegetation, and flies low over the water with quick wing beats. This relatively small duck has a big head and a flat, broad body. The breeding male is a rich sienna brown overall with white cheeks, a black cap and nape, and a bright-blue bill. The female is drab with a conspicuous dark stripe across the cheek. Nonbreeding males become gray. The ruddy duck can sink low into the water, grebe-like, and will often dive to escape danger. The breeding female (top) and breeding male (bottom) are illustrated.
