The female has gray mottled back and rusty bars and streaks in the rest of the body. The juvenile is similar to the female, but the back is rusty and gray. All age stages show a white area at the base of the long tail, which is readily seen when the bird is in flight. It is structurally similar to the Long-winged Harrier, but their ranges do not regularly overlap in Peru. It favors lake edges, marshes, and wet grasslands, but also inspects agricultural fields.
