Borneo; Sabah + Sarawak

26th April - 16th May 2026

Leader: Yeo Siew Teck

Borneo has one of the richest avifauna on earth and our trip explores several different ecosystems, from the mighty Mount Kinabalu to the pristine through to the lowland rainforest of Danum Valley, giving us the opportunity to record the majority of the islands endemic birds.
We begin our tour in the Crocker Mountain Range, with a chance to record many mid-altitude specialities which are difficult elsewhere such as Bornean and Mountain Barbets, Bornean Bulbul, Fruithunter and Bornean Leafbird, while a secluded hide gives us a chance of the once seldom-seen Bulwer's Pheasant, one of the worlds finest pheasants, along with Bornean Banded Pitta, Crested Partridge and perhaps Great Argus too.
‍
Nearby, we concentrate on the endemic hotspot of Mount Kinabalu that reaches a spectacular 4101 meters, although we will explore much lower altitudes. This area is cloaked by lush forest, mountain streams, an abundance of endemic orchids and most importantly, many fascinating bird species that are unique to the highlands of Borneo and include the enigmatic 'Whiteheads Trio' of endemics comprising a spiderhunter, trogon and broadbill. We then head to the lowlands, starting with the Kinabatangan River, home to the highly specialised Proboscis Monkey, rare Storm's Stork, eight species of hornbill, the little-known Bornean Ground Cuckoo and, occasionally even Bristlehead.
Saving the best till last we visit one of the world's oldest and most magnificent rainforests at Danum Valley. Based at the superb Borneo Rainforest Lodge, we will enjoy some of the best lowland rainforest birding in the world; seeking out some of Borneo's lowland specialities, including the bizarre Bristlehead and the stunning Blue-headed Pitta, one of six species of pitta possible.

Sarawak is an exciting addition to our comprehensive Sabah tour. Sarawak, The land of the Hornbill, was seldom on the birding circuit, yet our explorations have found some great birding sites. This weekinvolves some camping, and other nights staying in a family-run guesthouse. The two main targets on the extension are birds not found in Sabah - Dulit Frogmouth and Black Oriole, and there's also good chances at Hose's Broadbill and Bornean Frogmouth, along with a host of mid-altitude endemics that are easier here than Sabah.

Day 1:
Arrivals into Kota Kinabalu International Airport for an overnight stay.

‍Day 2:
Early departure south-west to an area of peat-swamp forest in search of Hook-billed Bulbul, a peat-swamp specialist not found elsewhere in the tour. Red-crowned Barbet and Scarlet-breasted Flowerpecker are also peat-swamp specialists, though we will require a great deal of luck to see the latter. Feeding flocks here contain a variety of Sundaic species including Black-winged Flycatcher Shrike, Green Iora, Red-billed and Chestnut-bellied Malkoha, with a chance of Bornean Black Magpie.After a morning here we continue to Sarawak, transfering to 4wd pick-ups and head inland to the small village at the base of the mountain by the late-afternoon. Night in local guesthouse.

‍Day 3:
Slow walk up into the mountains during the morning along an old logging track. During the early morning a variety of bulbuls, including Scaly-breasted are possible but once we start to gain in elevation the goodies become possible – Black Oriole being the main target. In the past we have seen Rail babbler, Hose’s Broadbill, Bock’s Hawk Cuckoo, Mountain Serpent Eagle, Black-throated Wren Babbler, Ferruginous Partridge, Blue-banded and Bornean Banded Pittas. Some of the more common Bornean endemics are likely, including Bornean Leafbird, Bornean Bulbul, Black-sided Flowerpecker and Pygmy Heleia, along with Temminck’s Babbler. In the evening we will go in search of the elusive and seldom-seen Bornean Frogmouth. Night camping.

‍Day 4:
A full day birding along the old logging road in search of the previously mentioned species. Spending some time above camp gives us the opportunity to see Mountain Serpent Eagle, Fruit-hunter and Whitehead’s Spiderhunter. Night camping.

‍Day 5:
Morning walk back down to the roadhead, birding along the way. Our 4wd vehicles then drive us further inland to another small village situated in a fertile valley deep in the Kelabit Highlands. In the evening we go in search of one of the most little-known endemics of Borneo – Dulit Frogmouth. Night in a local guesthouse.

‍Day 6:
Pre-dawn/post-dusk for Dulit Frogmouth. During day roadside birding in search of several possibilities with Rail-babbler, Whitehead’s Spiderhunter, Hose’s Broadbill, Blue-banded and Bornean Banded Pittas, Mountain Serpent Eagle, all present though difficult. Night in a local guesthouse.

‍Day 7:
After pre-dawn night-birding if required and early morning birding, before driving back into Sabah and heading into the hills, where out secluded guesthouse - Borneo Girl Entomology Camp on the ridge towards Mount True Madi awaits us.

‍Day 8:
A special morning, as we sit and wait in a hide in the forest for Bulwer's Pheasant to appear. Over covid lockdown a feeding station was setup for the species, which has proven highly successful, with near-daily sightings of one of the world's most enigmatic species. In addition, we have a chance of Crested Partridge, Dayak Blue Flycatcher, Temminck's Babbler, Great Argus and Bornean Banded Pitta here.
Away from the hide, in the mid to late morning, birding along the road holds the localised Bornean Bulbul, Bornean Leafbird, Pygmy Heleia, Bornean Barbet and Mountain Barbet. We will then transfer to the Kinabalu National Park for a five-night stay on the slopes of the magnificent Mount Kinabalu.

‍Days 9-12:
At 4101 metres, Mount Kinabalu is the highest peak between the Himalaya and Papua New Guinea. The slopes of this mountain are still cloaked in lush, montane forest, containing a huge diversity of plants, insects, mammals, amphibians, and most importantly for us - birds, many of which are endemic to the highlands of Borneo.
We will split our time here between birding along the road towards the summit and working the excellent series of trails. We will be searching in particular for The montane specialities, including Kinabalu Serpent Eagle, Red-breasted and Crimson-headed Partridges, Bare-headed, Sunda and Rufous-hooded Laughingthrushes, Mountain Wren-Babbler, Bornean Stubtail, Mountain Black-eye, Pale-faced Bulbul, Bornean Swiftlet, Bornean Green Magpie, Bornean Whistler, Bornean Whistling-thrush, Bornean Forktail, Fruithunter, the superb Whitehead's trio (Trogon, Broadbill, and Spiderhunter) and the elusive Everett's Thrush. Depending on our success we may also take a day trip to the lower slopes of Mount Kinabalu, to Poring Hot Springs, which has a markedly different avifauna. Here we have chances to find the dazzling Blue-banded and Bornean Banded Pittas as well as one of Borneo's most difficult endemics, Hose's Broadbill. There are also a range of rare species possible including White-necked Babbler, White-tailed Flycatcher, Rufous-collared and Banded Kingfishers, and even Chestnut-capped Thrush.

‍Day 13:
After some final birding on the mountain if required we travel overland to the Kinabatangan River stopping along Gomantong Caves, famous for their huge numbers of breeding swiftlets and bats. This offers us the chance to identify the four swiftlet species (Mossy-nest, Black-nest, Edible-nest and Plume-toed) by studying the structure of their nests, undoubtedly the easiest way to separate this difficult group! The nearby forest might give our first taste of lowland forest birds which sometimes include Black-throated Babbler or Black-crowned Pitta. We then continue to our lodge on the banks of the Kinabatangan River, our comfortable and exotic home for the next three nights.

‍Days 14-15:
Cruising along the river we will hope to find the rare StormÍs Stork and We will spend the night in the idyllic setting of the banks of the Kinabatangan.
We have two full days to explore the Kinabatangan River, mostly by cruising along the main river and its quiet, twisting tributaries. Our main target here is the Bornean Ground-cuckoo, one of Borneo's most mysterious and least-known birds, which has regularly been recorded here in recent years.
As we cruise along in the comfort of our boat we will also expect to see the rare Storm's Stork, several species of hornbills including Wrinkled and White-crowned Hornbills, and a fine selection of raptors and other lowland forest species. We will always be looking out for interesting mammals and will make a special effort to see the unique Proboscis Monkey, with a good chance of others including Bornean Pygmy Elephant and Bornean Orang-utan.
Heading out at night we will look for feeding Buffy Fish Owls along the river banks, and hope for something rarer like a Large Frogmouth or Oriental Bay Owl. Nights along the Kinabatangan River.

‍Day 16:
After a final morning cruise along the Kinabatangan we drive south to Lahad Datu after lunch. From here we will travel by minibus into the heart of the fabulous Danum Valley Conservation Area to our base for the next four nights, the luxurious Borneo Rainforest Lodge. The spectacular rainforest here is home to some of the rarest and most stunning birds in south-east Asia, including several species endemic to Borneo and the forest we will be birding in is renowned for being one of the best spots to search for them. Night at Borneo Rainforest Lodge.

‍Days 17-19:
Our lodge at Danum Valley is located in superb primary rainforest and excellent birding begins in the grounds. An extensive trail system allows us to search for some of the more elusive forest species and the fantastic canopy walkway allows a unique insight into species which often remain hidden in the treetops.
Among the specialities we will be searching for are six species of resident pitta, including endemic Black-crowned, Blue-headed, Blue-banded and Bornean Banded Pittas. The spectacular Bristlehead, a monotypic family, will be another big target and deep in the forest we will search for Black-throated and Striped Wren Babblers, Bornean Ground Babbler, Bornean and Sunda Blue Flycatchers together with a fantastic supporting cast of innumerable woodpeckers, babblers, trogons and hornbills.
The area is also rich in mammals and highlights are likely to include Bornean Orang-utan and Bornean Gibbon. Night-birding is often rewarded by Buffy Fish Owl or Brown Wood Owl and mammals may include several species of flying squirrel, Bornean Loris, up to five species of civet, Leopard Cat and if we are really lucky perhaps even a Marbled Cat or Sunda Clouded Leopard - all of which we've seen on previous tours. Nights at Borneo Rainforest Lodge.

‍Day 20:
After a final morning of birding we will have to tear ourselves away from this fantastic area and bid farewell to Danum Valley, as we return to Lahad Datu and take a flight back to Kota Kinabalu. Night at Kota Kinabalu.

‍Day 21:
International departures from Kota Kinabalu International Airport.
