Goldschnabel-Sumpfhuhn Mustelirallus erythrops

A fairly small rail, mostly gray below and olive-brown above with bicolored bill (red base, yellow tip) and pinkish legs. Black and white barring on vent can be difficult to see. Shy and typically uncommon to rare. Most often found in dense marshy habitats, including flooded rice fields and pastures. However, not necessarily tied to water, and can also be found in moist forest with dense understory. Even its vocalizations aren’t well-known, but makes a low, fast, cooing trill.
