Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at over 482,000 km2 (182,800 square miles), including adjacent smaller islands and Krakatoa archipelago. It is an elongated landmass with the longest axis running approximately 1,790 km northwest-southeast, crossing the equator near the centre. At its widest point, the island spans 435 km. Sumatra is a highly seismic island. Huge earthquakes have been recorded throughout history. It has a population of around 60 million people. Medan is the largest city with a population in excess of 2.5 million people; Palembang is the second city with over 1.5 million.
The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa archipelago, separates Sumatra from Java.

The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeastern area contains large plains and lowlands with swamps, mangrove forest and complex river systems. The equator crosses the island at its centre in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid. Lush tropical rain forest once dominated the landscape.
Birding Sumatra
Sumatra has a wide range of plant species including 17 endemic genera and many animal species, but has lost almost 50% of its tropical rainforest in the last 35 years. Many species are now critically endangered, such as the Sumatran Ground Cuckoo, Sumatran Tiger, Sumatran Elephant, Sumatran Rhinoceros and the Sumatran Orangutan. Deforestation on the island has also resulted in serious seasonal smoke haze over neighbouring countries of Malaysia and Singapore. The widespread deforestation and other environmental destruction in Sumatra and other parts of Indonesia has often been described by academics as an ecocide. Conservation areas have not been spared from destruction, either.

Sumatra still supports a wide range of vegetation types that are home to a rich variety of species, including 17 endemic genera of plants. Unique species include the Sumatran pine which dominates the Sumatran tropical pine forests of the higher mountainsides in the north of the island and rainforest plants such as Rafflesia arnoldii (the world’s largest individual flower), and the titan arum (the world’s largest unbranched inflorescence). It is home to 200 mammal species including none endemics and around 580 bird species. There 14 more endemic mammals on the nearby Mentawai Islands. There are about 300 freshwater fish species in Sumatra. and 93 amphibian species, 21 of which are endemic.

The Indonesian government has plans to protect Sumatra’s remaining forests and there are more than 10 national parks, including three which are listed as the Tropical Rainforest Heritage of Sumatra World Heritage Site – Gunung Leuser National Park, Kerinci Seblat National Park and Bukit Barisan Selatan National Park. The Berbak National Park is one of three national parks in Indonesia listed as a wetland of international importance under the Ramsar Convention.

2017 [10 October] - Carlos Bocos
InformationEntering the wet season in the Greater Sundas can be a risky strategy with the weather but can be excellent for birding, and so this tour proved, with a very high rate of endemics bagged in both islands. Java, hosting an incredible number of endangered species, gave us excellent birding with highlights like Javan Hawk-eagle, Chestnut-bellied Partridge, Javan Cochoa, Sunda and Horsfield´s thrushes, Javan Trogon, Javan Banded Pitta, Javan Owlet, Javan Frogmouth, White-breasted Babbler, Dark-backed Imperial Pigeon, Pink-headed Fruit-dove, Javan Laughingthrush, Volcano Swiftlet or both Tawny-breasted and Pin-tailed Parrotfinches. Way Kambas treated us well with excellent night birding as expected, including Oriental Bay Owl, Bonaparte's Nightjar, Reddish Scops-owl and Sunda, Large and Gould's Frogmouths. Daytime birding was also excellent with the endangered White-winged Duck, Cinnamon-headed Green-pigeon, Malayan Banded Pitta, Olive-backed Flameback, Rufous-tailed Shama and many more. Both Gunung Kerinci and Bukit Tapan were also great and the number of highlights, countless. Schneider's Pitta, Salvadori's Pheasant, Sumatran Cochoa, Rimator, Sumatran Peacock Pheasant, Red-billed Partridge, Sumatran Frogmouth, Sumatran and Blue-faced Leafbirds, Ruby-throated Bulbul, Graceful Pitta and Marbled Wren Babbler. -
2018 [03 March] - Rob Hutchinson - Java & Sumatra
PDF ReportAn ever increasing number of recognised endemics make these two Indonesian islands even more attractive, and this custom tour targeted those, following a traditional birding circuit but with the exciting addition of the Mentawai islands. We began on Java where Gunung Gede-Pangrango was pleasantly free of the hoards of hikers that descend later in the year, and we racked up a great list of endemic; Javan Scops Owl at touching distance, Javan Frogmouth, Javan Owlet, Chestnut-bellied Partridge, Javan Trogon, Javan Crocias, Javan Cochoa, Crescent-chested and Whitebibbed Babblers, Flame-fronted and Brown-headed Barbets, Pygmy Bushtit and the spectacular Javan Kingfisher. -
2018 [06 June] - Rob Gordijn & Helen Rijkes - Western Sumatra
PDF ReportSumatra was our second stop in our year of travelling, we wanted a destination in Indonesia in June and the weather in Sumatra seemed favourable. With two new pitta’s and lots of other endemics this was an easy choice. Since we only allotted 10 days we chose to do western Sumatra with the best site for most endemics (Kerinci) and since we were travelling via Padang we added one of the offshore islands (Mentawai). -
2018 [09 September] - Mike Nelson - Sumatra & Java
PDF ReportWith a tasty list of endemics, it’s no wonder our West Java and Sumatra tour is very popular and our third tour this year didn’t disappoint, notching up a total of 341 species, including a fantastic crop of endemics and local specialties. -

PDF ReportWith only a little over two weeks, I had to be pretty selective on where to visit in Indonesia. The decision was made to concentrate on a number of species that are unfortunately critically endangered. -
2019 [08 August] - Mike Nelson - Sumatra & West Java
PDF ReportThe two huge islands of Sumatra and Java comprise half of the Greater Sundas. From steamy lowlands to high volcanic peaks these two islands boast over 80 endemic bird species, a number that makes them a priority for many avid birders. -
2022 [08 August] - Craig Robson
PDF ReportSumatra is one of the most endemic-rich islands in Asia and the World as a whole – a destination high on the priority list of many birders. This was the rst Birdquest tour there since the pandemic, and also one of our most successful ever, a remarkable achievement when considering what we have all just been through over the last few years. Although Sumatra has a reputation for being a ‘dicult’ birding destination, we recorded almost all of the endemics and near-endemics, with just a handful of misses, thanks to our network of excellent local guides and remarkably smooth-running logistics. -
2024 [02 February] - Rob Arnold
Report...Sumatra is the world’s fifth largest island, after Borneo, and it possesses an interesting range of endemic bird species. My Singaporean friend KC and I are here to try to winkle some of these out, including the usual trogon and pittas, but especially the Sumatran Ground-Cuckoo, cousin of the Bornean and the mainland Coral-Billed Cuckoos... -
2024 [08 August] - Pete Morris
PDF ReportOur 2024 tour to Sumatra was a brilliant success! A great and enthusiastic group, largely good weather, and, other than the odd re-arranged flight, good logistics, all helped, allowing us to find nearly all of our target birds. Enggano and Nias were not part of our itinerary, and of the remaining endemics, we saw all but two, one of which we heard! -
2024 [09 September] - Carlos Bocos
PDF ReportOur second Java and Sumatra tour was an absolute and resounded success. We harvested a mass total of 312 bird species, with 15 heard only, plus 27 species of mammals. We did well with the endemics, recorded 22 species of nightbirds and saw some endangered birds throughout like White-winged Duck and Milky Stork. A tour all about quality birds...
