Abstract

Indonesia’s many islands, large and small, make it an important center of avian diversity and endemism. Current biogeographic understanding, however, is limited by the lack of modern genetic samples for comparative analyses from most of these islands, and conservation efforts are hampered by the paucity of recent information from small islands peripheral to major, more commonly visited  islands. In November and December 2016, we visited Maratua, an oceanic coral atoll 50 km east of Borneo, and Bawean, a volcanic island on the Sunda continental shelf 150 km north of Java, to survey birds and collect specimens for morphological and genetic analysis. We detected many of the birds on Maratua’s historical lists and added several new resident and migratory species. Notably, we did not detect the Maratua White-rumped Shama (Copsychus malabaricus barbouri). On Bawean, we found the forests to be nearly silent and detected remarkably few resident land-bird species overall. The           severe population reduction of C. m. barbouri on Maratua and the drastic reduction of forest birds on Bawean probably result from overexploitation by the cage-bird trade in the first case and a combination of the cage-bird trade and pellet-gun hunting in the second.

Abstract

The Kangean islands are a biologically poorly known archipelago situated in the Java Sea, Indonesia, approximately 120 km directly north of Bali. These islands host an avifauna comprising at least 13 endemic subspecies, two of which have by some sources recently been considered species. We combine historical published literature with our own surveys of the archipelago in 2007–2008, 2010 and 2023 to produce a complete list of the islands’ birds (n=140 species) and their distribution across the islands. We evaluate in more detail the conservation status of all endemic taxa, as well as several others we consider to be of concern. Despite its listing as Vulnerable on the IUCN Red List, the endemic Kangean Tit-babbler Mixornis prillwitzi is highly tolerant of habitat degradation and is among the islands’ least threatened birds. However, because of trapping, the archipelago’s endemic taxon of Red-breasted Parakeet Psittacula alexandri kangeanensis, and its populations of Green Junglefowl Gallus varius and Common Hill Myna Gracula religiosa are likely at risk of extirpation. The endemic taxon of White-rumped Shama Copsychus malabaricus, sometimes afforded species rank as ‘Kangean Shama’ C. nigricauda, may already be (at least functionally) extinct in the main archipelago. We recommend longer and more detailed surveys of the islands’ birds, and that an effective protected area is established on main Kangean island, which hosts the largest area of remaining forest in the archipelago and most of its endemic taxa.

Abstract

Sulawesi is an important endemicity hotspot in Southeast Asia, with over 100 endemic species distributed on the island. Despite a long history of avian research on Sulawesi that has played a significant role in the development of evolutionary theory, many ornithological aspects remain unknown. The last few decades have seen novel discoveries, for example, in the form of new species range extensions and species discoveries in the face of ongoing habitat loss and conversion. We here report on a range extension and notes of morphological descriptions of the endemic Diabolical Nightjar and Indonesian Serin in Southeast Sulawesi, adding to our knowledge of the distribution of Sulawesi’s avifauna, especially in the southeastern part in which visits from ornithologists are less frequent. A review of recent museum collections adds another new locality for Diabolical Nightjar in South Sulawesi. Future taxonomic studies are needed to elucidate the status of both species, especially in the Indonesian Serin, as the subtle differences in the coloration of the forehead, rump, and upper tail covert may indicate more than one taxon exists in Sulawesi. In addition, we provide an annotated checklist of birds observed during the fieldwork encompassing areas around Kolaka and Makassar.
