Adults have a green bill with a bluish base, a red eye, and reddish- to yellowish brown legs and feet. Most of their head and their throat, breast, and belly are slate gray. Their nape and shoulders are chestnut, their back olive, and their tail black. Immatures and juveniles have not been described. Voice: The slaty-breasted rail mostly calls during the day. It makes a "ariety of loud, resounding, noisy cries, including 'po-quit kwaa kwaa kwaa', 'po-peek' and 'po-pereek'", often for many minutes and usually in a duet. Another vocalization is "an irritated, rapidly repeated series of 'quir' notes".
