Burmese black leaf monkey mainly lives in trees. They like to live in groups, in small groups, usually 3-10 in each group, and larger groups have about 20. They usually move and feed in the upper layers of trees, rarely go to the ground, have certain activity patterns and relatively fixed residences, and their activity range is about 3-5 square kilometers. Led by a male monkey, they forage in the morning and afternoon and rest at noon. They sleep in trees or caves at night. They are agile and light, good at climbing and jumping, especially active in the morning and evening, and live in natural caves between cliffs at night. They are very vigilant. Before entering the cave at dusk every day, the male monkey who serves as the leader of the group will enter the cave first to observe. When no abnormalities are found, other members will enter in turn. The last to enter the cave are pregnant females with cubs.

The main food of the Burmese black leaf monkey is leaves, flower buds and wild fruits, and occasionally eats insects and other small animals.

The Burmese black leaf monkey has an unclear breeding season. It usually mates in February and March, with a gestation period of about 160 days and gives birth in August and September. Adult female monkeys usually give birth to one baby per year and reach sexual maturity at 4-5 years old.
