Hope for rare singing gibbons as pair are released into the wild

Two Siamang gibbons rescued from the illegal pet trade have been rehabilitated in a new Indonesian centre

The forest chorus of South Sumatra in Indonesia has some of its finest singers back: a pair of rare Siamang gibbons, rescued from the illegal pet trade, have been released into the wild.

Siamang gibbons (Symphalangus syndactylus) are known for their distinctive large throat sacs. But their powerful, haunting voices, used for communication and marking territory, are a blessing and a curse.
