ULTIMATE SUMATRA TOUR REPORT 2026

22 / 26 July - 17 August 2026

Craig Robson

Sumatra has a reputation for being a ‘difficult’ birding destination, and is one of the most endemic-rich islands in Asia and the World as a whole – a high priority destination for many birders. Our previous comprehensive Sumatra tour in 2024, was one of our most successful ever, so it was most satisfying to match those impressive achievements on our latest tour. In 2026 we saw all of the endemics and significant near-endemics and regional specialities, with the exception of Aceh Bulbul, thanks in no small part to our network of excellent local guides and smooth-running logistics.

Some of the main avian highlights amongst the more than 350 species recorded in 2026 included: White-winged Duck, Red-billed, Roll’s and Sumatran Partridges, Bronze-tailed Peacock- and Salvadori’s Pheasants, Malayan Crested Fireback, the peerless Sumatran Ground Cuckoo, Mentawai Malkoha, Barusan Cuckoo-Dove, Silvery Pigeon, Sumatran Green Pigeon, Pink-headed Fruit Dove, Milky Stork, Bonaparte’s and Salvadori’s Nightjars, Sumatran and Sunda Frogmouths, Rajah, Mentawai and Simeulue Scops Owls, Sumatran Trogon, ‘Sumatran’ (Grey-headed) Woodpecker, Simeulue Parrot, Graceful and Schneider’s Pittas, Sumatran Drongo, Sumatran Treepie, Bar-winged Prinia, Spot-necked, Cream-striped and Sumatran Bulbuls, Sangkar White-eye, Marbled, Sumatran and Rusty-breasted Wren-Babblers, Sumatran Babbler, Sumatran Laughingthrush, Sumatran Cochoa, Rufous-vented Niltava, Sumatran Blue Robin, Shiny and Brown-winged Whistling Thrushes, Sumatran Shortwing, Sumatran Flowerpecker, and Sumatran and Blue-masked Leafbirds. There was plenty of interest for the all-round naturalist too, including 35 species of mammal and around 90 species of butterfly.

The pre-tour extension began at Lampung Airport in southern Sumatra, where the group gathered together before we headed off to the Way Titias area of Bukit Barisan Selatan National Park, in the south-west Sumatran uplands.

Sumatran Ground Cuckoo was obviously our primary target at Way Titias, and we had the best part of two days to try and find one. Is wasn’t too long before we heard the unmistakable cry of the ground cuckoo, but it took many hours and a great deal of planning and fore-thought before we finally succeeded in getting prolonged views of a reactive pair in a secluded gully, right at the end of our stay. Sumatran Partridge, which is arguably the most important species to see in these forests, was also seen very well. Other highlights included Ferruginous Partridge, our first glimpses of Bronze-tailed Peacock-Pheasant, Sunda Owlet, a flyby Malaysian Blue-banded Kingfisher, Sumatran Trogon, Dusky and Green Broadbill, Spotted Fantail, Maroon-breasted Philentoma, Ruby-throated Bulbul, our first looks at Sunda Scimitar Babbler, Marbled Wren-, Spot-necked and Sumatran Babblers, Blue Nuthatch, and Fulvous-chested Flycatcher.

We returned to Lampung and, after meeting Main Tour only clients at the airport, proceeded to Way Kambas National Park, where we spent the next four nights. Thankfully, the park is open again these days, and the covid-era is but a distant memory. With excellent local guide Hari at the helm, we were able to fully explore various tracks and trails by day and night. The national park is not really famous for Sumatran endemics but instead, supports a huge range of scarce and impressive regional specialities, which this year included: the now seldom seen White-winged Duck at a secluded forest pool, Malayan Crested Fireback, Chestnut-bellied Malkoha, the scarce Malaysian Hawk-Cuckoo, Little Green Pigeon, superb Storm’s Storks, Grey-headed Fish Eagle, Red-naped, Diard’s and Scarlet-rumped Trogons, Black Hornbill, Red-bearded Bee-eater, Blue-eared and Rufous-backed Dwarf Kingfishers, stunning Rufous-collared Kingfishers, Sooty, Black-eared and the range-restricted Red-crowned Barbet, Rufous Piculet, a range of woodpeckers, including Grey-and-buff, Buff-necked, Buff-rumped, Olive-backed, Crimson-winged and Banded, Black-thighed Falconet, Blue-rumped Parrot, Black-and-red Broadbill, Malayan Banded Pitta, Rufous-winged Philentoma, Dark-throated Oriole at super-close range, Malayan Black Magpie, numerous babblers, including Fluffy-backed Tit-, Chestnut-rumped, Sooty-capped, Rufous-crowned, Malayan Black-capped, Sumatran, White-chested, Ferruginous and Horsfield’s, Rufous-tailed Shama, Malaysian Blue and Grey-chested Jungle Flycatchers, and Yellow-breasted, Crimson-breasted and Scarlet-headed Flowerpeckers. By night we enjoyed good looks at the unique near-endemic Bonaparte’s Nightjar, as well as Malaysian Eared, Large-tailed and Savanna Nightjars, Large, Sunda and Gould’s Frogmouths (the latter on a nest which we also admired by day), a stunning Oriental Bay Owl at ridiculously close range, Reddish and Sunda Scops Owls, and Buffy Fish Owl. Mammal highlights included a couple of rarely-seen Asian Elephants, Malay Civet, some cool bats, Malaysian Slow Loris traversing utility cables in the village, and an unexpected Red-cheeked Flying Squirrel. We also enjoyed some great hospitality, with Hari’s wife preparing us some of the best food that we had in Sumatra.

The following morning we returned to Lampung Airport, and then flew via Jakarta to Padang on the west coast of Sumatra. Early the next morning we were heading across the ocean by fast ferry to the island of Sipora, in the Mentawai Islands, for a two-night stay. Much had changed here since my previous visit four years earlier, particularly regarding access and the deterioration of roads and tracks that we had used to reach good habitat back then. We managed to figure things out however, and succeeded in seeing all of the specialities. Just a single (recently split) Mentawai Malkoha, thanks to local guide Mateus, but it sat in the open for a surprisingly long period. Barusan Cuckoo-Dove was easy enough and, after dark, we soon obtained good views of Mentawai Scops Owl. We also clocked-up the most significant potential future splits, in the form of  ‘Barusan’ (Thick-billed) Green Pigeon, ‘Mentawai’ (Hair-crested) and ‘Mentawai Ashy’ Drongos, and ‘Barusan’ (Olive-winged) Bulbul and, right at the end, ‘Mentawai’ (Crested) Serpent Eagle. We also had great views of the undescribed local form of Sunda Frogmouth and Red-legged Crake. Two rare Kloss’s Gibbons were heard on our final morning, and we had some good mammal sightings, with the endemic Golden-bellied Treeshrew, Mentawai Squirrel, and Mentawai Three-striped Squirrel all seen.

Back on the mainland, we spent another night in Padang, before the lengthy drive to Kerinci the next morning. One of the most famous birding destinations in Indonesia, Gunung Kerinci has some of the most sought-after endemics, and we had three full days at our disposal. Birding the trail up the mountain has received some unnecessarily bad press in the past. Perhaps we were fortunate again with the weather this year, but the conditions really didn’t seem that difficult and the birds largely showed themselves readily. Top of the list were Schneider’s Pitta, Sumatran Cochoa, Bronze-tailed Peacock-Pheasant and Sumatran Frogmouth, and we had great views of all four (with the latter at a day-roost). We also all enjoyed wonderful close views of Red-billed Partridge, Rusty-breasted Wren-Babbler, Sumatran Blue Robin, Sumatran Shortwing, and Shiny Whistling Thrush. A little more effort was required to find Pink-headed Fruit Dove, Rufous-vented Niltava, and Brown-winged Whistling Thrush, but they all showed well. Sumatran Wren-Babbler was rather tricky but showed well enough for most of us. A night foray brought close views of three roosting Salvadori’s Pheasants (thanks to a tip-off), and Rajah Scops Owl. Other goodies included Salvadori’s Nightjar, Sumatran Trogon, Sunda Minivet, Sunda Warbler, Black-capped White-eye, Blue Nuthatch, and Sumatran Flowerpecker.

From Kerinci we moved south again to Sungai Penuh, and spent a couple of mornings exploring the Tapan Road. The very extensive tract of excellent forest here continues to be a great birding location. Top of our sightings this time were unbelievable close views of the endemic Graceful Pitta and superb Marbled Wren-Babbler. However, we were most fortunate to encounter a small foraging group of Sumatran Leafbirds, an endemic that has suffered greatly at the hands of unscrupulous bird-trappers, and is now hard to locate at easily accessible locations. Amongst the many other great birds here, we particularly enjoyed Sumatran Green Pigeon, Rhinoceros and Wreathed Hornbills, Sumatran Trogon, Yellow-crowned and Gold-whiskered Barbets, Sunda Cuckooshrike, Sumatran Treepie, Black-and-crimson Oriole, Scaly-breasted, Cream-striped and Spot-necked Bulbuls, Sangkar White-eye, Grey-headed Babbler, and Sunda Forktail.

On our other morning based at Sungai Penuh, we made a fairly short drive to the south, before following the Danau Kaco Trail into a little-known tract of protected forest. This is the area where Sumatran Ground Cuckoos are most readily seen these days, having become habituated to a couple spots in the forest, thanks to the efforts of some local bird guides. While not guaranteed, the chances of an encounter are high, and we were not to be disappointed this time. It was not long before we heard their familiar mournful calls and, after following a narrow trail to a small ‘arena’, a pair of ground cuckoos scurried and crept into view, with one spending a long time perched on a mossy log right in front of us, occasionally calling with it’s head tilted back. We didn’t add many other species here, but our first Sumatran Bulbuls showed well.

From Sungai Penuh we followed the coast back to Padang. After another overnight stay, we flew direct to Medan the following morning. With the rest of the day at our disposal, we once again visited Percut Mudflats, situated on the coast to the north-east of the city. Reaching our observation point at the start of a falling high tide, it was not long before patches of mud started to appear, and our first Milky Storks showed up. We were to count 11 in total, and were also very impressed by the excellent variety of migratory shorebirds and terns present; totaling more than 1500 individuals, and including: Eurasian Curlew, Bar-tailed Godwit, Great Knot, Broad-billed, Curlew and Terek Sandpipers, and Little and Common Terns.

The next morning we were back at Medan Airport again, this time taking a flight to Banda Aceh, the capital of Aceh Province in the far north of Sumatra, before making the longish drive to Meulaboh, our three-night base for visiting the Gunung Leuser Ecosystem (National Park). There was no time for birding on this travel day unfortunately.

We were out before dawn the following morning, with local guide Agus, and we enjoyed two full days and an early morning session in this superb vast forest. So much quieter than Gunung Kerinci, and with very easy roadside birding, we had little problem connecting with our remaining targets. Great views of a group of Roll’s Partridges were obtained in a secluded gully, the highly distinctive Sumatran Laughingthrush showed surprisingly easy and well, the stunning Sumatran Woodpecker (bizarrely still lumped in Grey-headed in some modern checklists) eventually gave itself up, and we had many sightings of Sumatran Drongo and Blue-masked Leafbird (both much commoner up here than further south). Our only failure, and indeed the only notable one of the entire tour, was not being able to find Aceh Bulbul. Many hours spent scanning the only available site, produced neither site nor sound of this scarce and threatened bird. Other highlights were the local form of Common Green Magpie, Crested Jayshrike, Bar-winged Prinia, Yellow-breasted Warbler, great views of Sunda, Chestnut-capped and Black Laughingthrushes, and Rufous-browed and Pygmy Flycatchers. Mammals included our only sighting of Thomas’s Langur.

We flew back to Medan for another overnight stay, before embarking on the final leg of the tour by flying to Simeulue, at the northern end of the west Sumatran (Barusan) Islands chain. Based at a now much improved and very comfortable surfcamp, we were ferried around to a number of forested locations in the south and east of the island, where we soon succeeded in locating all of the endemics. Great views were had of Silvery Pigeon (albeit only in flight), the diminutive but rather angry-looking Simeulue Scops Owl, ‘Simeulue’ (Crested) Serpent Eagle, record numbers of Simeulue Parrot, ‘Simeulue’ (White-bellied) Woodpecker, and ‘Simeulue’ Ashy Drongo. Great Eared Nightjar, the local form of Changeable Hawk-Eagle, Rufous-backed Dwarf Kingfisher, Fiery Minivet, Mangrove Whistler and Copper-throated Sunbird were also seen well.

Our Sumatran birding adventure drew to a close, as we returned by air to Medan, and then onwards with our international flight connections.

SYSTEMATIC LIST OF SPECIES RECORDED DURING THE TOUR
Species marked with the diamond symbol (◊) are either endemic to the country or local region or considered ‘special’ birds for some other reason (e.g., it is only seen on one or two Birdquest tours; it is difficult to see across all or most of its range; the local form is endemic or restricted-range and may in future be treated as a full species).

The species names and taxonomy used in the bird list follows AviList v2025 (AviList Core Team 2025. AviList: The Global Avian Checklist, v2025); this was the current version when the checklist for the tour report was created.
Where the subspecies seen is/are known, these are often given in parentheses at the end of the species comment.

The species names and taxonomy used in the mammal list follow the mammal list on the iGoTerra website (www.igoterra.com). This list largely follows IUCN (International Union for Conservation of Nature) taxonomy with just a few modifications. It is listed in family order, alphabetically by genera within families. Some alternative names are given in parentheses.
