BehaviorUnlike other monkeys, Uakari has a very short tail but is extremely agile in the process of moving, transferring branches using two hands and two legs.
They live in large herds and have a clear social hierarchy. A flock of about 100 children, during the day will divide into groups of 5-10 to eat, the rest will watch, at night they will go up to the big trees and sleep there. During the dry season, Uakari monkeys often go to the ground to search for grains or fruit that have fallen to the ground. But in the rainy season, when the river rises, they will have to live on trees.
The food of the red-faced Uakari monkey is usually fruit, plants and some insects. They have very strong jaws, which can crush hard seeds to remove the core.
Decline in the number of individualsEvery two years, Uakari monkeys usually give birth to only one litter of 1-2 young. The reproductive age of females is at 3 years, while in males it is 6 years. Therefore, they cannot grow the number of species fast. Primates such as the red-faced Uakari monkey are often hunted in the Amazon jungle for food, so their numbers are dwindling, not to mention the consequences of excessive logging that has shrunk the environment. their habitat.
In 2008 the World Wildlife Conservation Union (IUCN) reported that the number of Uakari monkeys had decreased by at least 30% over the past 30 years, due to hunting and habitat loss. This is a positive result because another report in 1994 showed that this species was in danger of extinction. Although the conservation status has improved, in fact, the number of species is still on a decreasing trend.
