Red-tailed monkey

Description

The red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon (Cercopithecus ascanius) is a species of primate in the family Cercopithecidae. It is found in Angola, Cameroon, Central African Republic, Democratic Republic of the Congo, Kenya, Rwanda, South Sudan, Tanzania, Uganda, Zambia, and possibly Burundi. The red-tailed monkey is usually black, red, or orange. Although native to this region, it has spread north and south as well as it can survive in different habitats and under different conditions. It is a distinct creature in its habitats and is gradually becoming endangered due to deforestation and over-exploitation through hunting and predation. The red-tailed monkey is named as it sounds, for its red coloration of the tail's underside as well as the bi-coloration of the tail as the reddish color increases from the base to the tip. There are other features characteristic to this mammal as well such as the white nose and cheeks in the midst of black or dark grey body fur. Red-tailed monkeys also have very large, elastic cheeks which are used in gathering food and storing it in their mouths for safety. Sizes of their bodies range between individuals as well as between the sexes as males are larger than the females. Body length ranges from 1 to 2 foot (12-24 inches), without the tail included, males being on the upper end of the scale and females being on the lower. Adult males also weigh between 7 and 10 pounds and females weigh slightly less between 6 and 8 pounds. The tail length can reach up to 35 inches long which can be twice the body length for some red-tailed monkeys. The tail helps the monkeys achieve balance. Red-tailed monkeys communicate using different methods which are characteristic of communicating specific behaviors or things. Physical and vocal communication are used between members of social groups of these monkeys to demonstrate social dominance, submissiveness, or greeting. Vocal communication is used between members of social groups of red-tailed monkeys in which the more submissive monkey will make a soft, oscillating call to its elder. Physical communication is exhibited in nose to nose greetings where two red-tailed guenons touch their noses together. This is a sign of affection and can be followed by playful behavior. Visual communication is used as a sign of warning to others to stay away and as a defense against predators.
