Delacour’s Langur Distribution
Delacour’s Langur Characteristics
The Delacour’s langur, also known as Delacour’s Lutung, is an endangered Lutung native to northern Vietnam.
- Delacour’s langurs are known for the distinct patches of white fur on their thighs that contrast with their black fur.
- Females also have a patch of white fur close to their genitalia. Like its relatives in the Langur and Lutung families, the Delacour’s langur has tufts of gray hair on its cheeks and a tuft on its head.
- Like many of its relatives, baby Delacour’s langur has bright orange fur for the first 4 months of life.
- This odd feature has been the subject of several scientific theories and studies.
- You might think bright colors would make the baby more visible to predators, but the color seems to help babies.
Delacour’s Langur Facts
- The species is named after Jean Théodore Delacour, a French-American ornithologist.
- Delacour’s langurs prefer rocky habitats and live in “karst forests, ” basically tropical forests with limestone caves and cliffs.
- They are among the few mammals referred to as trogloxenes – animals that spend most of their lives in burrows.
- Any adult in the group can look around, quickly spot the infants and move to protect them when danger is detected.
- The color patterns of the Delacour langur give the monkey its local name, “Vooc quan đùi trang“, which is Vietnamese for “white pants langur“.
