Le Colobe guereza
Colobus guereza , the guereza colobus or Kilimanjaro guereza (among others), is a species that is part of the mammals Primates . It is a monkey of the family Cercopithecidae . It is a species of Old World monkeys. It is found in much of western central Africa and in eastern Africa, that is to say Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda and Chad. The species includes several subspecies of different appearance. It has a distinctive appearance to which its name alludes; the long fringes of white hair that run along each side of its black trunk make it a kind of coat. Its face is framed with white hair and it has a large white tail in the form of a tuft.
The guereza is diurnal and arboreal, found in both deciduous and coniferous forests. It is an adaptable species that can tolerate disturbances to its habitat and prefers secondary forest near rivers or lakes. Although it was once thought to eat only leaves, it also eats seeds, fruits and arthropods. It is able to digest plant matter with a high fibre content thanks to its specialised stomach, but it can only eat a small number of plant species at any one time. It is hunted by raptors and some mammals such as the common chimpanzee and the leopard.
The Guereza lives in social groups of three to fifteen individuals. Typically these groups include a dominant male, several females, and their offspring. It reproduces polygynously, and copulation begins with vocal communication. After a gestation period of just over five months, babies are born with pink skin and white fur that darkens to adult coloration in three to four months. The Guereza is well known for its dawn song, the males' "roar" is a method of communicating over long distances: it reinforces territorial boundaries. It also makes other vocalizations and uses body postures, movements, and facial expressions to communicate.
