Species group · Mammals
WAnimals has 9 species of guenon, in the family Cercopithecidae.
Each one has its own full profile. This group does not replace them: it brings them together.
2 species in this group are in a threatened category according to the IUCN.
Recorded in 32 countries. The ones with the most species in the group:
Its white beard gives it the look of an old man; faced with danger it freezes rather than flees.
From
Its strategy in the face of danger is to freeze: it can stay completely motionless in the foliage for hours, and that stillness makes it so hard to spot that it is considered one of the most undercounted African primates in surveys.
From
Its white beard and orange brow band have made it one of the most recognisable monkeys in the world's zoos, though in the wild hardly anyone sees it.
From
There is a feral population on the island of Grenada, in the Caribbean, descended from animals carried on slave ships from West Africa more than three hundred years ago.
From
Its cheek pouches can hold as much fruit as its stomach, and it is often seen with its cheeks bulging with the haul as it flees a contested tree.
From
The classic studies on this group of monkeys showed that they have different alarm calls for leopard, eagle and snake, and that each triggers a specific response: climbing a tree, looking up or looking down. It was one of the first solid pieces of evidence for referential communication in a non-human animal.

Ranges calculated from the profiles that record the figure, not from all 9.
Young males leave their natal group on reaching maturity, while females stay for life in the group where they were born.
From
The males combine two distinct alarm calls into sequences that mean something different from what they mean separately: it is one of the most cited examples of protosyntax in a non-human animal.
