Its long tail is blackish with white sides, and the underparts are white. The long curved bill has no casque (a large display growth on the upper mandible of the bill).
Males and females look alike, although the male has a cream-colored bill, whereas the female’s is black with a cream stripe. Immature birds have dark grey upperparts, a cream bill, and a tail with a white tip. Its flight is slow and powerful.
