Birding the Lesser Sundas Islands

The Lesser Sundas (Nusa Tenggara Island group) is split into two provinces: Nusa Tenggara Barat and Nusa Tenggara Timur.West Nusa Tenggara (Indonesian: Nusa Tenggara Barat) is a province in south-central Indonesia. It covers the western portion of the Lesser Sunda Islands, except for Bali. The main Lesser Sunda Islands are, from west to east: Lombok, Sumbawa, Flores, Sumba, Timor, Alor archipelago, Barat Daya Islands, and Tanimbar Islands. The two largest islands in the province are Lombok in the west and the larger Sumbawa island in the east. Mataram, on Lombok, is the capital and largest city of the province. The province is administratively divided into six regencies (kabupaten) and one municipality (kotamadya).Lombok is mainly inhabited by the Sasak ethnic group, with a minority Balinese population, and Sumbawa is inhabited by Sumbawa and Bima ethnic groups. Each of these groups has a local language associated with it as well. The population of the province is 3.821.134; 71 percent of the population lives in Lombok.

The Lesser Sunda Islands differ from the large islands of Java or Sumatra in consisting of many small islands, sometimes divided by deep oceanic trenches. Movement of flora and fauna between islands is limited, leading to the evolution of a high rate of localized species, most famously the Komodo dragon.[5] As described by Alfred Wallace in The Malay Archipelago, the Wallace Line passes between Bali and Lombok, along the deep waters of the Lombok Strait which formed a water barrier even when lower sea levels linked the now-separated islands and landmasses on either side. The islands east of the Lombok Strait are part of Wallacea, and are thus characterised by a blend of wildlife of Asian and Australasian origin in this region.[7] Asian species predominate in the Lesser Sundas: Weber’s Line, which marks the boundary between the parts of Wallacea with mainly Asian and Australasian species respectively, runs to the east of the group. These islands have the driest climate in Indonesia.

  • NR Mount Tambora

    InformationSatellite View
    Mount Tambora, also known as Tomboro, is situated in the northern part of Sumbawa island. It is a segment of the Sunda Arc, a string of volcanic islands that make up the southern chain of the Indonesian archipelago. Tambora forms its own peninsula on Sumbawa, known as the Sanggar peninsula. To the north of the peninsula is the Flores Sea and to the south is the 86 kilometres (53 mi) long and 36 kilometres (22 mi) wide Saleh Bay. At the mouth of Saleh Bay there is an islet called Mojo. An 1896 survey records 56 species of birds including the crested white-eye. Several other zoological surveys followed and found other bird species, with over 90 bird species discoveries in this period, including yellow-crested cockatoos, Zoothera thrushes, Hill mynas, green junglefowl and rainbow lorikeets are hunted for the cagebird trade by the local people. Orange-footed scrubfowl are hunted for food. This bird exploitation has resulted in population declines, and the yellow-crested cockatoo is nearing extinction on Sumbawa island.

    …There were plenty of Small Blue Kingfishers, as well as a good range of large waterbirds, such as Little Black and Little Pied Cormorants, and a range of herons and egrets. A swimming group of Sunda Teal were somewhat distant, Pink-necked Green-pigeons were rather more obliging, and we had nice views of some migrant Rainbow Bee-eaters.

Some of the species we encountered in the late afternoon included the immaculate Black-naped Fruit Dove, Green Imperial Pigeon, Wallacean Drongo, Yellow-ringed White-eye, rare Sumba Brown Flycatcher and splendid Apricot-breasted Sunbird.

    …We then ventured away from the well-trodden route and headed to the small island of Roti once again, to see ‘Roti Boobook’, an undescribed Phylloscopus warbler and several near- Timor endemics and potential endemic splits. Although many of Timor's endemics aren't quite so gaudy, Black- banded Flycatcher, Buff-banded Bushbird, an undescribed nightjar and Timor Sparrow were all greatly admired, as was the sighting of an undescribed species of parrotfinch that we discovered on last year’s tour..

    I had the opportunity to visit Nusa Penida, Indonesia between 5 to 14 April 2016, to do some bird watching. Nusa Penida, is an island just east of Bali, Indonesia. It is west of Wallace’s Line, having an Asia avian composition. The immediately further east is the Island of Lombok on the other side of Wallace’a Line which, has an Austro-papuan avian composition. Nevertheless, there are some species that cross the line. Nusa Penida is dry by Indonesian standards have an extended dry season from April to November, and a short intense wet season from December to March...

    Sumbawa island is the part of lesser sunda area, it's located between Lombok, Flores and Sumba islands. In terms of birding activities, this island often missed or skipped by most of birders.
