Black-And-White Colobus Fact Sheet

  • Latin Name

    Colobus guereza
  • Class

  • Order

  • Range

    Black-and-white colobus are found across much of equatorial Africa.

  • Status

    Logging and habitat conversion for farming are the major threats to all habitats that support this species. Lincoln Park Zoo participates in the Colobus Species Survival Plan®, a shared conservation effort by zoos throughout the Association of Zoos and Aquariums.

  • Habitat

    They occupy the uppermost canopy of tropical forests, woodlands and wooded grassland (where they may feed and travel on the ground if there isn't a continuous pathway of trees). They can be found in lowlands and at high elevations. Black-and-white colobus are most abundant in secondary forests or along rivers.

  • Niche

    With a complex digestive system, these primates are designed to process leaves, but in the wild they also occasionally eat fruit, flowers, twigs, buds, seeds, shoots and insects. Black-and-white colobus are diurnal (active during the day) and arboreal (tree dwellers).

  • Life History

    • Black-and-white colobus live in troops of as many as nine individuals. Their home range is about 40 acres, including a preferred area from which other groups are chased but not permanently excluded. Visual and vocal displays occur when groups meet, and loud nocturnal and dawn choruses by adult males serve to space out groups.
    • Single young are born after a six-month gestation. Offspring are produced about every 20 months. Maturity occurs at about five years.
