The Trus Madi Conservation Area at the Crocker Range in Sabah is well known among insect and moth lovers as the place to go and see the hundreds of insects of the tropical montane hill forests. The Trus Madi Entomology Camp, better known as the Borneo Girl Jungle Camp was set up in the conservation area primarily to study the insect life there.
Insect screens with special lights to attract the insects were erected at the both sides of a ridge near the camp. On most nights, these screens were swamped with insects, mainly moths of all shapes and sizes, cicadas, beetles, cricket and wasps. April I was told is the peak month.
Every morning the resident Pig-tailed Macaque will make its way to the ridge and pick out the biggest and juiciest cicadas that are still on the screen. It will tear away the wings before biting off its head and then the body. These fruit eating monkeys would not pass off a chance of tasty snack that is rich in proteins as well. We saw some squirrels around but did not see them taking any of the insects.
During the night, another opportunistic raider was on standby. The Barred Eagle-Owl waits patiently at the near-by tree for some of the larger moths and cicadas to fly by before swooping down to pick it up. These insects will supplement their usual diet of rodents and squirrels.
When dawn breaks, the rest of the insectivorous birds would gather at the trees on both side of the ridge to start their day with easy pickings. The Ashy Drongos and the White-throated Fantails will sally out for the smaller flying moths. Flocks of the endemic Chestnut-crested Yuhinas will flush out the rest of the insects for a quick meal. While the Black-bellied Malkohas and the Red-bearded Bee-eaters wait for the larger ones. Even the small tailorbirds were able to pick and choose their food from the buffet in front of them.
This feasting must be a ritual for these birds every morning. Free and easy food in the cool montane air. For the bird watchers and photographers, it is an opportunity not to be missed.
