Abstract

Bird surveys and long-term bird monitoring in Gunung Halimun-Salak National Park were conducted between 1998 and 2009 to obtain comprehensive data on the bird species in the area. Compilation of bird data from this study and other studies have recorded a total of 271 species, which is about 53.4% of all Javan birds (507 species) or 16.9% of all Indonesian birds (1605 species). As an important bird area, Gunung Halimun-Salak National Park is home to 43 Indonesian and Javan endemic species. Among the endemics, 32 species are restricted range species. Gaps in the protection status of the bird species are discussed. The results of this study show that Gunung Halimun-Salak National Park has the highest richness of bird species in the Java-Bali region and the conservation of its endemic and threatened species should be given main priority.

Abstract

Crescent-chested Babbler is endemic to the island of Java and Bali, Indonesia and protected by the Indonesian Government Regulation No. 7/ 1999. Its population is suspected to be declining due to ongoing habitat destruction and fragmentation. Information on its eco-biology is very poorly known. There is a need to obtain the information in order to conserve this species and its habitat. Morphometric and molt stages were recorded from 23 individuals captured by mist-nets between February and April 2016. There were variations in morphometric measurement in weight, head bill length, wing length and tail length in Cisarua Forest habitat, but no significant difference was found (F2.19 = 0.822, P> 0.05) in body weight among the three different habitats. This habitat has sufficient resource for Crescent-crested Babbler for molt activity during the study.

Abstract

The Wallacean Region continues to be widely unexplored even in such relatively well-known animal groups as birds (Aves). We report on the results of an ornithological expedition from late Nov 2013 through early Jan 2014 to eastern Sulawesi and a number of satellite islands (Togian, Peleng, Taliabu) as well as Ternate. The expedition targeted and succeeded with the collection of 7–10 bird taxa previously documented by us and other researchers but still undescribed to science. In this contribution, we provide details on numerous first records of bird species outside their previously known geographic or elevational ranges observed or otherwise recorded during this expedition. We also document what appears to be a genuinely new taxon, possibly at the species level of kingfisher from Sulawesi that has been overlooked by previous ornithologists. Our results underscore our fragmentary knowledge of the composition of the avifauna of eastern Indonesia, and demonstrate that there continues to be a high degree of cryptic, undescribed avian diversity on these islands more than a century and a half after they were visited by Alfred Russel Wallace and other collectors.
