What are the characteristics of the golden snub-nosed monkey's living habits?

The golden snub-nosed monkey has soft fur and an upturned nose. There are 6 species: the Myanmar snub-nosed monkey, the Nujiang snub-nosed monkey, the Sichuan golden snub-nosed monkey, the Yunnan snub-nosed monkey, the Guizhou snub-nosed monkey, and the Tonkin snub-nosed monkey. Apart from the Myanmar snub-nosed monkey and the Tonkin snub-nosed monkey, all of them are rare animals endemic to China. They live in groups in high mountain dense forests, feeding on berries, bamboo shoots, and moss, and they also like to eat bird eggs and other meat. Their habitat is at very high altitude, and the long hair on their bodies helps them withstand the cold.
Habitat environment
The golden snub-nosed monkey is a typical forest arboreal animal, living year-round in forests at an altitude of 1500-3300 m. Its vegetation types and vertical distribution zones belong to four vegetation types: subtropical mountain evergreen and deciduous broad-leaved mixed forest, subtropical deciduous broad-leaved forest and evergreen coniferous forest, and secondary coniferous and broad-leaved mixed forest. As the seasons change, they do not migrate horizontally, but only move vertically within their habitat environment. They live in groups, and each large group uses family-based small groups as its unit of activity. The largest group can reach more than 600 individuals. Among primates, such a huge group is also rare.
Food habits
Golden snub-nosed monkeys live in groups in high mountain dense forests. They mainly live in trees, and also look for things to eat on the ground. They feed on wild fruits, tender buds, bamboo shoots, and mosses. Their main food includes leaves, tender twigs, flowers, and fruits; they also eat bark and tree roots, and they love to eat insects, birds, and bird eggs.
Social habits
Golden snub-nosed monkeys have a typical family lifestyle, and members take care of one another, foraging together and playing and resting together. In a golden snub-nosed monkey family, the juvenile golden snub-nosed monkeys are strongly curious and very mischievous, and are also much doted on by their parents, but once a young male monkey reaches adulthood, he is driven out of the home by his father and can only go into the wild to live independently.
Growth and reproduction
Each year, autumn is the mating season for golden snub-nosed monkeys. Females reach sexual maturity earlier than males, at about 4-5 years for females, while males are late, at around 7 years. Mating occurs throughout the year, but the peak mating period is the three months from August to October. The gestation period is about 6 months, and most give birth from March to April, though a few also give birth in February or May. The gestation period of the female monkey is about 6 months, usually one infant per birth, occasionally two. The face of a newborn monkey is dark blue, its fur is brown, and its cry sounds like a baby weeping. After one month, its weight reaches more than one kilogram. In adult monkey groups, the ratio of males to females is about 1:2. As the altitude of the habitat rises, the mating season of different species of golden snub-nosed monkeys is delayed.
