This study describes the vocal repertoire of forest litter frog Leptobrachium hasseltii from Situgunung Resort, Mount Gede Pangrango National Park. Two types of calls were identified: advertisement call and aggressive call. Each types were represented by two different characteristics thus four types of calls were examined. The kruskall and wallis test was used to test the difference of nine features. Pearson’s correlation test also used to determine the relationship of all call features to air temperature and body size. Dominant frequency of all call types was relatively similar. Advertisement calls type I was emitted in short duration and fewer notes than advertisement call type II. Aggressive call type I and have longer call duration compared to both of advertisement call. However the introductory note of aggressive call type II was more longer than the others. Aggressive call of L. hasseltii tended to be discrete (territorial and encounter) and represented two different continuums. This were caused by the extreme differences of both calls in duration and distance between males when emitting calls. Dominan frequencies of all call types inverse correlated with body size of frogs. Most of temporal features of advertisement call type II correlated with body size and only call duration were longer with increasingly air temperature. Interpulse-interval and pulse period were more longer by increasing the body size, while the introductory note, pulse rate and pulse repetition rate were becoming shortened and it could predict male body size to facilitated competition between males, thus serves as mate selection indicator. Key words: advertisement call, agressif call, Leptobrachium hasseltii, Situgunung resort, social interaction

Javan Hawk-Eagle (JHE, Nisaetus bartelsi) which is endemic raptor in the natural forests of Java, Indonesia is categorized as one of the endangered. Small population size, severe habitat loss, forest fragmentation, and illegal hunting have contributed to the ‘‘endangered’’ status of this species. Moreover, conservation of this species has become a national priority. This study was being conducted because of the lack of information about the distribution of JHE’s remnants habitat which caused the proposed conservation strategies for JHE become difficult. This study aimed for updating data of JHE’s remnants habitat in West Java, analyzed its habitat patches distribution, and estimated the number of its populations. The previous study determined the habitat suitability probability modelling of JHE with used landsat images in 2002 at southern part of West Java. This study updated the model using the same logistic regression model equation in West Java overall. This study identified 17 remnant habitat patches (3 955 km2) scattered in West Java. The comparison with previous study showed that the size and number of patches was increased with the predicted number of JHE’s populations were about 39-195 (median = 117) pairs in southern part of West Java. Based on the results, we offer three recommendations to increase the survival of JHE’s habitat in West Java.Keywords: GIS, habitat remnants, logistic regression, Nisaetus bartelsi, patch.

Gunung Walat University Forest (GWUF) consist of several type of tree, two of them are Agathis (Agathis loranthifolia) and Schima (Schima walichii) stand. Different types of plantation forest might create fragments that affect bird communities. As a consequence of habitat fragmentation, the amount of habitat ecotone is increase and create edge effect. The objectives of this study were to (1) analyze whether there were edge effects for birds on Agathis and Schima stand, (2) analyze bird species found in ecotonal and species in non-ecotonal habitats, (3) analyze how birds responded to the presence of ecotone. This research was conducted in Agathis and Schima stands (edge and interior) in GWUF. Birds were surveyed by using point count. Bird diversity was calculated using Shannon-Wienner Indices, followed by Kruskal-Wallis tests, and similarity of communities was tested by using Bray-Curtis. Bird response to ecotone were described using histograms. The results showed that the abundance (Kruskal-Wallis test; χ2 =11,42, df=2, P<0,05) and species richness (Kruskal-Wallis test; χ2 =10,39, df=2, P<0,05) were higher in ecotone. Each stand has specialist species. Ecotonal habitat consists of Cacomantis sonneratii, Cacomantis sepulcralis, Surniculus lugubris, Centropus bengalensis, Hirundo tahitica, and Pycnonotus aurigaster. Schima stand consists of Enicurus leschenaulti, Oriolus chinensis, and Stachyris melanothorax, while Agathis stand do not have specialist species. About 41% of the bird species were able to be mapped into model as ecotone neutral-generalist, ecotone shy-specialist, ecotone conspicuous- specialist, and ecotonal species.Keywords: bird communities, ecotone, edge effect, GWUF

Javan coucal (Centropus nigrorufus) is one of the endemic birds of Java that has limited distribution in coastal areas. This study aimed to determine the spatial distribution and habitat preference of javan coucal in Wonorejo Region, in the East Coast of Surabaya. The spatial distribution and habitat preference were analyzed using dispersion index (ID) and Jacob index respectively. The results showed that Javan Coucal distribution was clumped, indicated by ID value > 1 for mangrove forests, inactive ponds and active ponds. The Jacob index (Dhi) were 0,75, 0,41 and -0,68 for inactive ponds, mangrove forests and active ponds, respectively. This result indicated that javan coucal preferred inactive ponds and the mangrove forests, and they tend to avoide active pond. The habitat factors affecting the javan coucal encounters were perch height (t=2,655; p=0,014), distance from coast (t=4,539; p=0,000) and air temperature (t=2,675; p=0,013). The regression equation was Y=67,041+0,678 (perch height) + 0,020 (distance from coast)-2,373(air temperature). Keywords: habitat preference, javan coucal, spatial distribution, Wonorejo

Succession after disturbance can affect the response of the bird community at each stage of habitat succession. Research on the impact of succession on birds has never been done in Papua, so this research is needed to understand how birds can survive habitat changes. This study aimed to analyze bird communities and their responses to successional stages of habitats, i.e., shrubs, agriculture, mixed plantation forest, young secondary forest, old secondary forest, and primary forest. Data collection was done from January 2023 to October 2023. Bird data (species and numbers) were collected using the point count method. Vegetation data (species and density) were collected by using the plot method, and abiotic data (air temperature, humidity, and light intensity) were collected using a dry-wet thermometer and a lux meter. The Shannon-Wiener diversity indices (H') were calculated for birds and trees. Correlation of the bird data against habitat and abiotic parameters was calculated. There were 11,272 birds from 55 species belonging to 25 families in the study area. The young secondary forest had the highest bird number and diversity (44 species; H' = 3,424), in line with the Intermediate Disturbance Hypothesis. Bird communities generally have a strong correlation with vegetation but a weak correlation with abiotic data. In light of conservation importance, young secondary forest held the highest bird species richness, while the primary forest provided habitat for some species that are highly dependent on natural forests.

The Jali River estuary a compact 5.45-hectare mosaic of nine habitat types on Java's south coast, was surveyed from March to May 2023 to assess its avian diversity and community structure. Using point counts (n=12 points, 3 replicates) conducted during low tide periods, we recorded 229 individual encounters representing 41 species from 19 families. The estuary exhibited high overall bird diversity (Shannon-Wiener H' = 3.212 ± 0.102) with moderate evenness (E' = 0.605). Standardized encounter rates varied across habitats, with the River and Pandanus stand showing the highest values. Analysis of community similarity (Bray-Curtis index) revealed five distinct ecological clusters, demonstrating that bird assemblage composition was driven more by habitat structure and resource availability than by spatial proximity. This was further supported by NMDS ordination (stress = 0.14) and SIMPER analysis, which identified key indicator species such as the Zitting Cisticola for open terrestrial clusters and the Cerulean Kingfisher for mangroves. The estuary's significant conservation value is highlighted by the presence of eight species protected under Indonesian law (PERMENLHK P.106/2018), including the globally Endangered Great Knot (Calidris tenuirostris) and the Vulnerable Christmas Frigatebird (Fregata andrewsi). These findings underscore that even small, heterogeneous estuaries can support high avian diversity and serve as vital refuges for threatened species, necessitating targeted conservation strategies focused on preserving critical habitats like mudflats, river corridors, and Casuarina stands.
