Large, plain rail with two color morphs, either dark chocolate brown or paler medium brown. Most with a few white feathers on head and back, especially dark morph. More often in pairs than alone, walking in the darkest areas of mangroves. Occurs in coastal salt lagoons, preferably in black mangrove and occasionally in red mangrove. Easy to find by voice, although sounds virtually identical to Mangrove Rail. In its habitat, the only all-brown rail with no barring on underparts. Range restricted and endangered, endemic to a small section of coast in northern Venezuela.
