A plump, mostly ground-dwelling bird with long yellowish legs, a dark blackish body, a tall light gray crest, a yellow bill, and a blood-red neck. Found in most habitats across the islands in its range, seemingly very adaptable. Local movements between islands frequently recorded. A loud species that calls often, most commonly giving a high-pitched squeaky “KEEK... KEEK KEEK” with a pause between the first and second notes. Unmistakable.
