In search of big-nosed monkys
2nd July 2008
On the road again
Shortly after returning from India, I was re-packing my gear and heading back to Heathrow, east-bound again, this time to south-east Asia and the forests of the world’s third largest island, Borneo. The focus of my trip was the oddly-faced Nasalis larvatus - the proboscis, or long-nosed monkey - distinctive because of the male’s large, bulbous protruding snout and listed by the IUCN as endnagered, due primarily to continuous habitat loss through deforestation.
Proboscis monkeys are endemic to Borneo’s low elevation mangrove forests and lowland riparian forests and, like the island’s other well-known primate, the Bornean orangutan, they are arboreal, meaning they spend most of their lives in trees, making them difficult to photograph at the best of times. To complicate matters further, I was attempting a unique shot, wanting to photograph a male leaping between trees, directly towards the camera. This wasn’t going to be easy.
Making a plan
At the airport, I met with my guide for the assignment, Cede Prudente. Cede is a well-known photographer in his own right, and a respected travel operator in Malaysian Borneo. We quickly went over the plan for the assignment before heading to camp. The plan was two-fold: initially we were going to set up remote cameras at the Labuk Bay sancturary for proboscis monkeys, before heading deeper into the forest and the Kinabatangan river, an area rich in wildlife and one of the last remaining habitats where proboscis monkeys and orangutans can thrive.
At camp I tested all the electronic equipment before storing it in a room separate from my sleeping quarters. One of the difficulties photographing in the tropics is heat and humidity. Air conditioning makes it comfortable for humans to sleep but taking camera equipment from a cool environment out into the jungle will cause moisture to form on lens elements and inside cameras. To overcome the problem, I had booked a room specially for the equipment, so that it could be stored overnight in a none-air conditioned climate.
Caught in a trap
In the morning we bagan setting up the camera traps. I had identified a position where a group of bachelor males visited regularly. The cameras were fixed to tripods, which were disguised to blend with the natural surroundings. To activate the shutters I was using infra red (IR) remote triggers, which I would fire manually from a distant, concealed position. As these triggers worked via line-of-sight, it was important to test them for accuracy.
Once the camera traps were set it was a question of sitting in place and waiting, normally something I’m happy to do, except here it was 30-degrees in the shade and close to 100% humidity. I have to admit that jungles are my least favourite environment in which to work and, after a few hours I was ready to scream, “I’m not a celebrity ... but GET ME OUT OF HERE!” Around the same time, the group of bachelor males began appearing in the trees around me. I was just going to have to put up with it!
Nikon delivers
For the shot I intended, my new Nikon D3’s were proving a real blessing. The ability to shoot at relatively high ISO values, without having to worry about digital noise, meant that, despite being in the low light of the forest, I could attain a sufficiently fast shutter speed to freeze the motion of the monkeys as they leapt. Knowing when to trigger the shutter came down to my knowledge of the subject and being able to read body language, together with the calculations I’d made for the delay between transmission and receipt of the IR signal.
