A large rail of forest floor on Calayan Island. Overall slaty-gray in color, slightly browner on the back, with a blackish face, long orange-red legs, and a fairly long, stout orange-red bill. Forages on the forest floor for snails, beetles, and millipedes. Similarly sized birds on Calayan include Barred Rail and Plain Bush-hen, but both avoid forest interior. Tabon Scrubfowl is found in forest, but lacks the orange bill and legs. Voice is a nasal squawk.
