Distinctive, ground-dwelling rainforest bird with reddish-brown back, gray face, black wings with bold white wingbars, strong legs and feet. Females have black-bordered orange throat, males white, both with gray sides and white underparts. Difficult to observe, although in some areas habituated to hikers. Forages in rainforest leaf litter, usually in pairs or small groups. Squeaking calls, given at dawn and dusk, recall sounds of Guinea Pigs.
