Azara’s Night Monkey Distribution

Azara’s Night Monkey Characteristics

Azara's Night Monkey

Azara’s night monkeys[1], also known as southern night monkeys and Azara’s owl monkeys, are native to the Gran Chaco region of South America, a vast area with many different ecosystems, from savannas to grasslands to dry spiny forests and gallery forests.

  • Azara’s night monkeys sport startling markings. Their abdomen is a beautiful orange color contrasting with the gray-brown woolly fur on their body. Their ears are short, round, and barely visible. Their facial expressions are highlighted by white hair.
  • Their large round eyes are hazel brown with large black pupils framed by light brown hair, making them resemble owls.
  • Their nose is flat and small, with the nostrils turning sides. Azara’s night monkeys have a throat pouch that allows them to make loud sounds.
  • They have large finger and toe pads and opposable thumbs. The large, muscular legs make these species agile jumpers.

Azara’s Night Monkey Facts

Aotus Azarae

  • The scientific name of this monkey is made up of two words: aotus, meaning without ears, and Azara, about Félix Manuel de Azara, a Spanish naturalist.
  • Genetic testing has shown that the males of this species mated pairs are the fathers of the babies they care for.
  • Grooming has barely been observed in feral groups, but captive studies show that monogamous pairs sometimes groom each other.
  • Although not quite visible, their eyes have a physical feature found in a few primate species. Each retina has only one type of cone, resulting in a lack of color vision.
  • Although primarily nocturnal, some populations of Azara’s night monkeys are unique among nocturnal monkeys in that they are active both day and night.
