Individual Diana monkeys may live for up to 20 years.

The Diana monkey is a noisy presence in the forest.

Diana monkeys retreat to the upper levels of the trees at night, though they do not make nests.

The zoo has the world's best Diana Monkey breeding program.

Animal life includes the elephant, bongo, chimpanzee, Diana monkey, and 263 species of birds.

She is a Cercopithecus diana, commonly known as a diana monkey, an endangered species in need of special care.

The same has been found in West African Diana monkey and Campbell's monkeys.

(The animal is a Cercopithecus diana monkey, which is an endangered species.)

The Diana monkey is found in the primeval forests, and does not thrive in secondary forests.

Diana monkeys belong to the guenons, a shy group of monkeys from the West African jungles.

Once the City Health Department got wind that a rare diana monkey was living in Manhattan Beach, they sprang into action.

The outside section will also be used by Mississippi alligators, the rare L'hoest and Diana monkeys, cheetah and leopards.

The Roloway monkey was previously considered a subspecies of the Diana monkey (Cercopithecus diana).

The most notable endangered species of fauna in the park are Diana monkey, giant bongo antelope, yellow-backed duiker and African elephant.

Though found in groups of only a few individuals, olive colobus monkeys are almost always seen in association with other Cercopithecus monkeys, particularly the Diana monkey.

It is now established that the animals previously classified as Cercopithecus salongo (common name Zaire Diana monkey) were in fact Dryas monkeys.

Like most primates, Diana monkeys can always carry diseases that can be communicated to humans, like yellow fever and tuberculosis, but they are not important carriers of these.

The Gorilla Kingdom area also features smaller enclosures housing Diana monkeys, black and white colobus, sooty mangabeys and white-cheeked gibbons.

In addition to serving as a means of predator avoidance, the close association with Diana monkeys is a mechanism used by male olive colobus monkeys to obtain new female mates.

These include the Diana monkey, Campbell's mona monkey, lesser spot-nosed monkey, western red colobus, king colobus and sooty mangabey, which coordinate anti-predator alarm calls.

The Diana monkey (Cercopithecus diana) is an Old World monkey found in West Africa, from Sierra Leone to Côte d'Ivoire.

The Primate Forest was first built in 1998 and features Allen's swamp monkeys, Colobus monkeys, Diana monkeys, Francois' Langurs, and white-cheeked gibbons.

They played recordings of either the crowned eagle shriek (a high-pitched kee-kee sound), the roar of a leopard or the croaking alarm calls the Diana monkeys make to warn of those animals.

Non-human primates of various species, including those listed as endangered, such as cottontop tamarins, baboons, chimpanzees, Diana monkeys, slow lorises, lemurs and gibbons are still available for purchase in the US.

Although the young are born in a fairly well developed condition, with open eyes and able to grasp their mother, at least in zoo conditions Diana monkey mothers appear anxious and possessive, rarely letting young infants leave them.

The Roloway monkey was previously considered a subspecies of the Diana monkey (Cercopithecus diana).

The Diana monkey (Cercopithecus diana) is an Old World monkey found in West Africa, from Sierra Leone to Côte d'Ivoire.

Some older sources treat the Dryas monkey as a subspecies of the Diana monkey and classify it as Cercopithecus diana dryas, but it is geographically isolated from any known Diana monkey population.
