The siamang gibbon live in Thailand, Indonesia and Malaysia, and are one of the most popular for the pet trade, which has led to a great reduction in the wild. Loss of habitat, plantation growing, logging and mining, all threaten this species, so to see species returned to the wild is incredibly good news. The male was very ill when first arrived, but was able to be rehabilitated before release back into the wild.
They started singing on their first day in the wild, which suggests that they were comfortable. They have been followed by a team for 4 months, in order to help show them what to eat, and to make sure that they are able to fend for themselves.
Pet gibbons are often found in tiny cages, where they cannot stretch out. Given their wild behaviour, which tends to find them swinging through the trees, at speeds of up to 35 miles an hour, and jumping up to 13m from tree to tree, being crammed into a small cage, when they can barely move.
The situation is not helped, by few people in their range are aware how endangered they are. Often, when informed the demand for pets disappears. As with many species, the conservation improves as locals know why they need protecting, and how close they are to extinction.
