has assessed the red-winged wood rail as being of Least Concern, though it has a somewhat limited range and an unknown population size that is believed to be decreasing. No immediate threats are known. It is seldom seen and its status in most of its range is unknown. "In view of its scarcity in some areas, its restricted distribution in threatened habitats and the lack of knowledge of its natural history, hespecies should be classified as a Data Deficient species."
