It was cold in Klamath Basin and most of the shallow streams and rivers were frozen. This feisty female was swimming and hunting in a small area right next to the frozen water. Ruddy Ducks have a habit of holding their stiff tails upright. Their legs are set far back on their bodies, and they have large webbed feet which aid in diving. Because of this, they have a hard time walking upright on land and often push themselves along the ground with their feet. When diving, the long stiff tail serves as a rudder. They are mostly herbivores, but they also dive for aquatic insects, crustaceans, mollusks, and snails.
