It has a gray bill with a white band, a shiny purple head, a white breast, yellow eyes and a dark gray back. The adult female has a pale brown head and body with a dark brown back, a dark bill with a more subtle light band than the male and brown eyes. The cinnamon neck ring is usually difficult to observe, unlike the white ring on its bill, which is why the bird is sometimes referred to as a "ringbill". These birds feed mainly by diving. They eat aquatic plants as well as some mollusks, aquatic insects and small fish.
