Our trip to Tangkoko Nature Reserve proved to be more of a study of tourists than tarsiers!
The reserve is much closer to Bunaken than to Lembeh, only about an hour's boat ride. When we arrived my husband, the guide and I were the only ones apparently about. Then, around dusk, other groups began appearing until there were about 25 of us clustered around the tarsier tree, a huge, hollowed out tree in which the tarsiers snooze during the day. Everyone was speaking different languages, getting their cameras ready, and loudly shushing one another.
As it grew darker and no tarsiers appeared, dissent among the groups grew more animated, with different nationalities falling into stereotypical displays of disgust with one another and the situation in general. The increasingly nervous guides began employing different strategies, first catching katydids and pinning them temptingly near the openings in the tree, then tapping on the tree, then full on banging the tree with sticks.
Finally, a single wide eyed Yoda face emerged at the opening, inciting an erruption of cameras blazing with flash as tourists jockied for position, not unlike the paparazi sighting a tiny shaved headed Britney Spears. In the blink of an eye the tarsier gave a mighty leap from the hollow, snatched the katydid bait with it's alien fingers, and leapt back into the hollow again, dissapearing for the night. The whole tarsier appearance was about a minute and a half.
The guides quickly rounded up their groups, loudly declaring "OH NOW YOU HAVE MANY GOOD PHOTOS! SO LUCKY!" and herded us back to our respective boats.
Okay, this story is not exactly addressing the thread, so I'll add this bit of advice. If you have non divers in tow with you on your Northern Sulawesi adventure, there is much more to do if you base out of Menado than Lembeh. For example, the Santika hotel has a lovely pool, guided tours, and a shuttle which will take you to THE MALL! which by the way has a great muck diving site right in front of it. Our DM was always begging to take us into Menado to show us the sights, and even sweetened the pot by promising to take me to his village where I could get a TATTOO! I will have to take him up on that during my next visit.
