Pennant’s Red Colobus Distribution

Pennant’s Red Colobus Characteristics

Pennant’s Colobus[1] or Pennant’s Red Colobus (Piliocolobus pennantii) is a species of arboreal primate in the Cercopithecidae family.

  • These African Old-monkeys are native to tropical Central Africa. One of the most distinctive characteristics of colobus monkeys is the lack of thumbs.
  • There is a bump where the thumb should be that looks like it was cut. The other fingers are extended to enable climbing, forming a hook to hold on to branches.
  • As with many climbing mammals, the limbs of Pennant’s red colobus are elongated. In general, Pennant Red Colobus males tend to be larger than females.
  • This species varies in mass from 7 to 11 kg. The length of the head and body generally varies between 53 and 63 cm, while the tail length varies between 60 and 70 cm.
  • The head is relatively small, and the belly is round. The subspecies of Pennant’s red colobus vary in coat coloration.
  • Shaggy hair varies between shades of brown and orange. The crown is usually dark red to almost black, and the hind legs and tail are usually dark brown.
  • The hair on the forehead is parted in the middle.

Pennant’s Red Colobus Facts

  • Like other red colobus monkeys, the Pennant’s red colobus lives in flocks that may consist of 12 to 80 individuals occupying a territory of 25 to 150 hectares.
  • They move nimbly through the canopy, jumping from tree to tree and using the elasticity of the branches.
  • Pennant’s red colobus monkeys have specialized teeth that can shred leaves and crack open rigid but flexible immature fruits and seeds embedded in the pulp.
  • The Pennant’s Red Colobus is also known for being quite noisy. Sounds described as “squawks” and “barks” can be critical auditory communications between individuals and troops.
  • The range of a group of Pennant’s colobus monkeys, often overlapping with other groups, can be 100 ha or more.
