Azara's night monkey is a nocturnal primate found from southern Bolivia through Paraguay to northern Argentina. It has large white patches above its eyes.
Its back is grayish brown with a reddish stripe along the side. White fur borders the central face, and large white patches sit above the eyes.
It rests with its family in tree hollows or dense foliage during the day, then becomes active in the trees at twilight to forage.
