|Black and White Colobus
Colobus guereza (aka Guereza)
The black and white colobus is
a heavy bodied animal with a long tail. The head
and body length is 20 to 35 inches and the tail
length is 25 to 35 inches. Weight is 14 to 32
pounds. Males are slightly larger than females.
The fur is distinctly black and white, and the
face is gray. The coat is glossy black. A
U-shaped white mantle of varying length surrounds
the face. The outside of the thigh is whitish, as
is the tail, and there are long white epaulettes
streaming from the shoulders. There are only four
digits on each hand, the thumb being absent.
Guerezas range throughout
equatorial Africa, in forest regions up to 9,800
feet. They are most abundant in secondary forests
or along rivers, but also live in woodlands and
A typical troop contains 6 to
10 members, led by an adult male. Each troop
maintains and defends a relatively small but
well-defined territory, within which only the
dominant male is allowed to mate. Young males
leave the group of their birth before they are
fully mature, while females usually stay with
their birth group for life. Young males usually
lead solitary lives, but some will take over
their own harem and create a new birth group.
Mating takes place year-round.
The gestation period is 6 months. Females reach
sexual maturity at about 4 years, males at about
6 years. Both the female and the male take part
in the parenting of the young.
Colobus monkeys feed on a wide
variety of leaves. Most feeding takes place
between early morning and midday, and again in
the early evening.
Other Habits and
Black and white colobus monkeys
spend most of their time sitting in the tops of
trees. However, when the trees are not densely
packed, they will feed and travel on the ground.
Individuals take turns sleeping
at night so that at least one monkey is awake at
all times to watch for predators.
