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.

Abstract

The Javan hawk-eagle (Nisaetus bartelsi Stresemann, 1924), an endangered bird endemic to Java island, faces significant extinction risks due to habitat loss and illegal hunting. To address this, the Javan Hawk-eagle Sanctuary Center (JHESC) was established within Mount Halimun Salak National Park, Bogor Regency, West Java, Indonesia, to support in-situ and ex-situ conservation efforts, focusing on rehabilitation and release. This study observed rehabilitation practices at the centre from April 2022 to March 2023, particularly the adequacy of its facilities and infrastructure regarding cage, feed, and health management. These aspects are essential for rehabilitation success. Based on observations, nine cage types were employed and tailored to specific rehabilitation stages: acceptance, treatment, isolation, pre-training, training, habituation, education, translocation, and hard release. These cages were designed with varying sizes and numbers to fulfil the needs of each stage. The centre's feeding management was supported by a well-organized storage system that maintained feed quality through proper air circulation and cleanliness. The centre consistently supplied three primary feeds: mice (Mus musculus), rats (Rattus norvegicus), and marmots (Cavia porcellus). Comprehensive infrastructure facilitated health management, including an animal clinic, isolation and treatment rooms, an operating room, an examination room, and a laboratory. Additionally, the veterinary medicines were accessible and staffed by qualified veterinarians to ensure the eagles were healthy from arrival to release. These robust facilities and practices can position the centre as a leading example for ex-situ conservation, prioritizing animal welfare while rehabilitating and releasing Javan hawk-eagles, with expectations of further enhancing eagle conservation efforts.

Abstract

The Critically Endangered Cacatua sulphurea abbotti is a unique subspecies of cockatoo, endemic to a single tiny Masakambing Island in Indonesia. Data procurement on the status and distribution of their wild population is urgently needed to determine the best conservation strategy for this species. Data were collected annually from 2008–2018 using a direct roost count method in a roosting tree. Only 10 cockatoos were recorded in 2008, but the number increased to 22 birds in 2018 (a 42.86% increase in a decade). The population was distributed across about 71% of the total area of the island, concentrated in the north-western part with a density of 1.56 (~2 birds/km²) in 2008, which increased to 3.44 (~3 birds/km²) in 2018. The zero-trapping policy enforced by the local government was likely effective in preventing population decline, although the population remains vulnerable due to nesting failure, presumably low genetic quality, and habitat destruction.
