Abstract

The objective of this study was to reveal the avian divesity at KBBK through direct and indirect obsemtion. Based on a 3 day obsemtion, we found 50 species of birds, consisted of 17 specieswaterbirds, 4 species of marsh birds, 1 species of shorebirds and 28 species of temstrial birds. The species richness was greatly reduced compared to the conditions in 1990 and 1991.

Abstract

The Edible-nest Swiftlet (Collocalia&ciphaga) has beenreceiving more attention lately due to the fact that this birdproduce an edible nests which fetch a high value in the international market. The original nesting habitat of this species islimestone caves. Since approximately a hundred year ago,people of Java has been successfully farmed the swiftlets inhouses which managed in such a way to resemble natural cavehabitat (Mardiastuti, 1996).There has been no previous study on the breeding ecologyof the Edible-nest Swiftlet in Indonesia, either in natural cavehabitats or in man-made nesting habitat. This paper aims toreveal the breeding success of the species and investigate thepossible causes of the breeding failure in swiftlet houses.

Abstract

The tricolored langur (Presbytis cruciger) is not only geographically restricted but is also believed to strongly depend on specific habitat types, particularly wetland ecosystems in northern Borneo. Despite its limited range and potential vulnerability, no comprehensive habitat assessment has been conducted within its distribution area. This study aims to model the habitat suitability of P. cruciger in the Danau Sentarum landscape using environmental variables derived from direct encounter data collected between 2021 and 2023, and analyzed using MaxEnt. Habitat suitability modeling revealed that 95.94% (228,658 ha) of the total study area (238,329 ha) was classified as unsuitable habitat. The remaining areas were categorized as marginally suitable (7,080 ha), suitable (1,977 ha), and highly suitable (614 ha). Highly suitable areas are concentrated in peat swamp forests, riparian forests, and lowland secondary forests located within 1 km of lake edges, extending into the hilly zones of the Danau Sentarum landscape. Among the environmental predictors, land cover contributed the most to the model, though it showed low permutation importance. In contrast, proximity to fire hotspots demonstrated high permutation importance, indicating an avoidance behavior towards fire-prone areas. The species preferred elevations ranging from 100 to 200 meters above sea level, with 8–25% slopes, and proximity to swamp forest and lake ecosystems. These results highlight the species' strong association with wetland ecosystems and underscore the importance of conserving these habitats to ensure its survival.
