Meliau Basin

Large Frogmouth (Batrachostomus auritus) Melaiu Basin, Sabah 6 September 2025 Callyn Yorke

Meliau Basin is a remote wilderness preserve in the lowlands of south-central Sabah. The setting along with the flora and fauna composition is similar to the Danum Valley. Since the Meliau Basin was one of the few remaining stands of lowland rainforest in Sabah and fairly accessible, I thought it might be worth a visit.

A travel agency in Kota Kinabalu assisted me with a five-night reservation package that included lodging, meals, guide service, a night drive, and transportation to and from Tawau ($320 US/ night).

A two-hour ($44 US) taxi ride from Lahad Datu ended at the Meliau Basin office in Tawau. From there, arrangements had been made for a 4WD shuttle to the Meliau Basin visitor center. Before leaving Tawau, I found a main street cafe and ordered a portion of rice and chicken (nasi ayam) that tasted like refrigerated leftovers. Ordinarily, I avoid eating at places without customers but it was the only food option near the MB office, the point of departure.

The roads leading to the Meliau Basin (MB) included paved stretches with koi pond-sized potholes and unpaved segments under construction. From the MB entry gate (Elev. 230 m), it was an additional twenty kilometers on a variably rough gravel road to the visitor center. That section traversed tall rainforest and roadside second-growth and would be the principal route for the wildlife night-drive.

A receptionist on her way home for the day, hastily introduced the lodge layout and routine, then assigned me to a deluxe room in an adjacent building. Access was at the top of a series of wooden staircases and walkways leading to a lengthy corridor of vacant rooms. Evidently, I would be the only guest at the facility, which appeared to have been carefully designed as a full-on, five-star eco-resort.

Compared with the basic lodging I had at the Danum Valley Study Center, this was a major upgrade. My spacious, rustic room included a balcony overlooking the forest and was just steps away from birding trails. These were among the most comfortable, perfectly located accommodations I would have in Sabah. Given that nearly all of the other ecolodges in Sabah were fully booked, it was somewhat of a mystery that there were no other guests. Judging by the scores of room vacancies, slick, mold covered walkways with missing planks, it appeared that this multi-million dollar resort and its skeleton crew were slowly being recycled back into the forest ecosystem.

A high-ceiling dining hall at the top level of the visitor center offered a small selection of veggies, meat and salad, neatly placed on a side counter. There was no sign of the kitchen staff. I sat alone at a banquet table with a dozen empty chairs on either side. An observation deck adjoined the dining area and, after sampling the food, I spent the remainder of the evening observing birds from the deck. Just before retiring to my room for the evening, I began to experience intermittently severe intestinal cramps.

Despite the cushy accommodations and optimism for a productive multi-day visit, my condition worsened overnight. By daybreak, I was exhausted from lack of sleep and had no appetite. When the resort staff discovered I had skipped two meals, one of the workers offered to drive me to the doctor in Tawau. I politely declined the kind offer, preferring to fast for a day, rehydrate frequently and starve out the unfriendly microbes that had colonized my gut, possibly originating from the nasi ayam lunch in Tawau.

The 24-hr. fasting remedy brought partial relief and was extended for another day. The following two days, together with Azree, the ranger-guide assigned to accompany me, were spent mostly in the immediate vicinity of the lodge.

A flatbed truck night drive on September 6, produced a few mammals , e.g., Palm Civet, Mouse Deer, Barking Deer, Thomas’s (Red) Flying Squirrel and two new birds for my trip report – Brown Hawk-Owl and Large Frogmouth.

Around the lodge there were numerous birds and mammals (e.g. Sambar Deer, Palm Civet, Plantain Squirrel, Long-tailed Macaque and North Borneo Gibbon), yielding some noteworthy observations and photo opportunities. I ended the brief MB visit with a comparatively short bird list, yet one that included a handful of new species for the Sabah trip report. I’m fairly certain that if I had been in normal health and stayed for the full five nights as originally planned, my Meliau field notes and digital image collection would have been significantly enhanced.
