Schmidt’s Red-Tailed Monkey Facts

Black-Cheeked White-Nosed Monkey

  • The Schmidt’s red-tailed monkey is named for its red coloration on the underside of its tail, as well as the bicolor coloration of its tail as the reddish color increases from the base to the tip.
  • It has a large cheek pouch holding almost as much food as its stomach. This adaptation allows it to practice retrieval and withdrawal methods while feeding.
  • The species is arboreal and diurnal, although adults often descend to the forest floor to search for fallen fruit.
  • Studies have shown these monkeys prefer to eat fruit at night while foraging for leaves and insects in the morning.
  • Schmidt’s red-tailed monkeys dwell in single-male groups consisting of one adult male, around 10 females, and their young.
