Chester Zoo Shares Photos of One-Day-Old Baby Gibbon
October 13, 2018
A rare baby Gibbon is the latest addition to the “biggest baby boom of mammals” on record at Chester Zoo.
The Silvery Gibbon – one of the world’s most threatened primates – was born to mom Tilu, age 10, and 19-year-old dad Alven on October 10 after a gestation of around 210 days.
The tiny, pink-faced primate is much too small to be sexed and therefore has not yet been named.
Gibbons are built for life in the trees and use their extra-long arms to swing from branch to branch, a technique called brachiation. As mom travels in the treetops, her baby clings tightly to her chest using its long fingers.
As the baby matures, it will begin to venture away from mom for brief periods. Like most Apes, Gibbons grow relatively slowly and depend on their mothers for a long period. Females give birth approximately once every three years. Silvery Gibbons are uncommon in zoos.
Silvery Gibbons, also known as Javan Gibbons, are found only on the Indonesian island of Java. These Apes are restricted to mountainous areas with dense forest cover. Though habitat loss is an issue on heavily-populated Java, the areas where Gibbons are found are very remote and rugged, so Gibbon populations have stabilized. Nonetheless, Silvery Gibbons are listed as Endangered by the International Union for Conservation of Nature (IUCN). Fewer than 5,000 individuals remain in more than 15 locations on the island. Only about half of the Gibbons live in protected areas.
