There, rangers are waiting with baskets of tropical fruit, usually bananas. A little distance away, on a wider wooden platform, tourists are busy snapping pictures.
This is the daily routine at 10am and 3pm at the Sepilok Orang Utan Rehabilitation Centre, 23km away from Sandakan on Sabah's east coast.
A shy creature, the "man of the jungle" does not hang around for long and in half an hour, they would have returned to the 4,294 hectare Sepilok-Kabili forest reserve.
With funding from the Sabah Government, the centre was set up in 1964 with the aim of rehabilitating orphaned, injured or displaced orang utan and returning them to the wild.
The programme has been highly successful and many orang utan have been rehabilitated over the years. Recently, a number have been translocated to the Tabin Wildlife Reserve in Lahad Datu, south of Sandakan.

Protecting The Young
The centre has indoor and outdoor nurseries and a wildlife clinic to treat orang utan and other injured animals. These facilities are, however, off limits to the public.
The rehabilitation process begins with a full health examination by the veterinarian, followed by a quarantine period to make sure that diseases the primate may carry are not spread to other individuals.
Young orang utan spend hours in outdoor nurseries, swinging from rope to rope and picking up skills such as the ability to find food, build nests and climbing, skills that they would otherwise learn from their mothers.
Scientists estimate that there are 11,000 orang utan in the wild in Sabah and that some 60 per cent live outside of protected areas.
For visitors seeking adventure, trekking is allowed on nature trails within the reserve. Trails vary from 250 metres to five kilometres and allow tourists the opportunity to experience the rainforest and mangrove swamps. It is possible to spot wild orang utan along these trails.
