Person of the forest? That's what the word "orangutan" means, and in the case of the Sumatran orangutan it seems appropriate. After all, it has been observed using tools, once thought to be the exclusive domain of humans; it uses sticks to probe for termites or extract seeds from fruits, and even passes this knowledge on the next generation. But as one of the world's slowest-breeding primates, giving birth just once every eight or nine years, it has few young. Faced with rapid population declines and the shrinking and fragmentation of its range, this extraordinary orangutan is at the risk of disappearing from the forest forever.
