The Four Keys to ID

    A large, big-headed diving duck with a gently sloping forehead and a stout neck. Its long bill meets the sloping forehead, creating a seamless look from the top of the crown to the tip of the bill. On the water it has an oval body and a short tail that gently slopes down into the water.
