Ground-breaking study to track orangutans
A ground-breaking study which combines ecology, astrophysics and drone technology is being used to track orangutans. Borneo's orangutan population has declined from 230,000 to an estimated 104,000 over the last century - making the species critically-endangered according to WWF.
