The eye is orange to red surrounded by bare blue-gray skin. The legs and feet are red. Juveniles' crowns are pale brown, their upperparts brown with dusky bars, and the breast and sides tawny brown with dusky bars.

The white-faced quail-dove forages singly or in pairs while walking on the ground, where it tends to favor dense cover. Its diet has not been documented but is assumed to be seeds, fallen fruits, and maybe insects.<p>The white-faced quail-dove roosts above the ground. It typically walks along branches or hops up to the roost rather than flying. Up to eight birds have been observed roosting together.<p>The whte-faced quail-dove's breeding season appears to vary within its range but has not been studied. Nests are loosely constructed of sticks and placed where they are well concealed, as high as 6 m (20 ft) above ground. The clutch size is two.<p>The white-faced quail-dove's song is "a low, hollow, mournful whoooo or whoo'oo."
