The chimpanzee is the closest animals to man and
because of the same habits like man it is assumed that many million years ago
we have the same ancestors. That evidence that it can make and use tools to
help for many uses is astounding.
The chimpanzee is the same species as the ‘great
apes’ such as gorillas and orang utans. The all share the same ape-like
feature. The chimpanzee has a slight stout body and strong stocky legs. When
the animals stands up the arms reach below the knees. Both hands and feet had
‘thumbs of the opposite and are extremely dexterous.
The face is long and rounded on top. The brow ridge
is very noticeable on top of the eyes and has a protruding mouth. The ears are large and round. The body is
covered with hair but the face is bare and has a flesh coloured skin. As the
Chimp grows older the skin darkens to black.
HABITAT
Today wild chimpanzee is only found in small areas
in the west and central Africa. The animals live only in wooded areas because
it spends mostly up in trees. It can be found in tropical forest, wooded
savannah and up mountains forests up to 3000m
When the chimpanzee is on the ground it walks on all
four. The hands hare turned in and it walks on its knuckles. It can develop
quite a speed and it moves in a fast gallop. It has also had been observed to
walk on its hind legs for quite a distance.
In the trees it walks either on all four, on its hind legs or swings
from branch to branch.
FAMILY
LIFE
The chimpanzee lives in a large group called the
community or unit group. This group can
be of about 100 animals but it is divided up within, to groups of six or seven
animals. The have a great territory and the borders are fiercely defended. The
relationships within the community or to other community are very complex.
Males are very aggressive to each other and it is not that seldom that they get
together and fatally wound another chimpanzee that entered the community.
All the activities are during the day and at night
they bend branches and interwoven them to form a nest, up in the tree, to sleep
in. It also has been seen some forming a nest during the day just to lay in it
and rest.
Chimpanzees are also very noisy. They make all sorts
of calls and noises. It varies from grunting noises when they eating, to loud
hoots, screams and drumming on trees. The reason for each sound is not known.
These noises can be heard 1km away.

DIET
Their main food is ripe fruit and they feed from
four hours or more. A further two hours the chimpanzee is eating leaves. They
prefer tree with lots on fruit on it so they can eat for hours from one place.
The chimps are also eating other vegetable such as stems, seed, bark, resin, flowers
and insects especially termites. It had
also been observed that they hunt and kill mammals with other chimps. They can
be anything from pigs, antelopes, baboons and monkeys. Once they killed the
mammals all friendship seized and the fighting over the carcass starts.
BREEDING
Breeding is at any time during a year. The chimps
become sexually mature at seven or eight years. However, the females only give
birth when she is 13. Although the
male’s sexual active but also only mate successfully when 13.
When female is ready for mating she will mate with
several males in the group. Sometimes a male and female bond more and they will
move aware from the group and mate only with one another.
Gestation is about 230 days. The female gives mostly
birth to a single young sometime twins. When the baby is born she cradles in
its arms. The moment it can cling the mother will carry it underside when she
moves. After about five months the baby will ride on the mother’s back.
The young one is weaned when it is about 3 years
old. After that it will stay with its mother for anything up to five, seven or
even 1 years. The mother will not give
birth for another six or seven years but only if the baby survives.
CHIMPANZEE
USE TOOLS
The chimpanzee is only second to human being to make
and use tools. They make and use sticks to pull branches with fruit closer. They
use stones to smash open fruits or shells. They even know to place the fruit on
a flat stone before break it open of smash the shells.
Termites are a favourite food for chimpanzees. They
are aware that if they stick their hands into the termite mounds they will be
bitten therefore they use sticks or stems to poke into the termites nest. They
strip the stick of bark and when the termites crawl up; eat the insect before
they bite them.
Adult males use of branches or rocks as weapons when
they fight or hunt.
IN
DANGER OF EXTINCTION
It assumed that the chimpanzees are already extinct
in various parts of the country where it was numerous. The overall count is
reduced from several millions at the beginning of the 20th century to
approximately 200,000. The decline has various reasons. One it was hunted
because the chimp raids crops. The other was exported to zoos. It was also
caught for research for medical purposes. The slow reproduction does not help
to increase the number. The destruction of habitat is also one of the main reasons.
Today the chimpanzee is classed as vulnerable and protected in many areas.
Experts classed the chimpanzees as primates and they
belong to the Pongidae family with one species – Pan troglodytes – and three
subspecies
Mask Chimpanzee – Pan troglodytes verus
Black-faced chimpanzee – Pan troglodytes troglodytes
Long-haired chimpanzee – Pan troglodytes
schweinfurtii
The pygmy chimpanzee – Pan paniscus is some times
considered as a separate species.
