Abstract

Bird communities are the composition of several bird species that live together in the same place, time and interact with other birds. The diversity of birds in an area can be used as an indicator of stabilizing an area. Changes of vegetation structures due to logging practices can affect the availability of resources for bird communities. The objective of the research was to examine diversity, richness, bird species abundance and bird community similarity at HS1 (logged forest 1974), HS2 (logged forest 1989/1990) and HS3 (fully logged forest 1989/1990) in Seblat Nature Recreation Park (SNRP). The research was conducted in July – September 2013. Data collection was conducted by point count method (total 36 points) and mist net method (total 4752 nets hours). The Research showed 85 bird’s species from 33 families were recorded. HS2 was highest value of diversity and richness (H ‘= 3.63, DMG = 10.07). The highest relative abundance species in HS1 was Emerald Dove (Chalcophaps indica), while HS2 and HS3 were Slender-billed Crow (Corvus enca). The bird community similarity was highest in HS2 and HS3 (ISj = 0.58).How to CiteSusanto, E., Mulyani, Y. A., Suryobroto, B. (2016).

Abstract

The Komodo dragon (Varanus komodoensis) of East Nusa Tenggara, Indonesia, is an endemic species protected by Indonesian law, mostly due to its population size and limited distribution. The natural distribution of the Komodo dragon is limited to Komodo National Park and several areas on the island of Flores and its surroundings. However, increasing population and tourism in its natural habitat might increase the conflict between the Komodo dragon and humans. To study the impact of human activities on the behavior of the Komodo dragon, we constructed an ethogram to catalog the behavioral inventories of the Komodo to enable future quantitative comparison. The Komodo dragon ethogram was obtained from observations in Loh Buaya and Loh Baru Resorts, Rinca Island, Komodo National Park. Observations were made on 10 adult males, 13 adult females, 12 juveniles, and 3 hatchlings Komodo dragons. Data were collected during July-September 2019, February-March 2020, and June-September 2020. Based on observations, observed behavior was grouped into 9 categories based on their function. Among them are sexual behavior, parental behavior, antagonistic behavior, ingestion/egestion, maintenance, movement, resting, and investigative.

Abstract

IPB Dramaga Campus in Bogor has been recognized to hold a high diversity of birds, while at the same time is also experiencing disturbance due to human activities. During the covid-19 pandemic in 2020-early 2022, most human activities on campus were decreased. Observations made during lockdown indicated that birds were seen more easily in various habitats on campus. The objective of this study was to describe bird species richness and composition before the period of lockdown and after the pandemic (post-lockdown). Bird surveys were conducted monthly in 2019 and from January to May 2023 to obtain a bird species list. Mist nets were set up monthly for 3 months in 2019 and 2023 to obtain demographic data. Descriptive analysis was conducted by comparing the results with previous data collected by Uni Konservasi Fauna (UKF) and Cikabayan Bird Banding Club (CBC). The number of bird species between the two periods did not differ significantly; there were 66 species in while in 2023 there were 60 species. In both periods bird species composition was dominated by the family of Cuculidae, and the dominant feeding guild was insectivores.

Abstract

Great Argus (Argusianus argus) is a globally threatened species that is protected by law in Indonesia. This species is a habitat specialist that tends to be confined to primary forests and is susceptible to human disturbance and environmental change. Sungai Wain Protected Forest (SWPF) is an isolated lowland rainforest in Kalimantan. The rising deforestation rate has threatened species sustainability in recent decades, including the Great Argus in SWPF. This study aimed to systematically analyze camera trap data on the Great Argus's abundance, activity patterns, and habitat suitability prediction in SWPF. We used camera trap data from 2018-2022 at the SWPF. Great Argus's lowest relative abundance index was in 2020, and the highest was in 2022. Overall, the relative abundance index of the Great Argus was approximately 3.125 independent events per 100-day trap night. The activity pattern of the Great Argus started at dawn and then constantly decreased until dusk. The habitat suitability prediction for the Great Argus was mostly in primary forests. Distance to road and building were the variables that contributed the most to the results of habitat suitability modeling. Habitat loss and suitability are the determining factors for the sustainability of significant argus populations.

Abstract

Flores hawk-eagle (Nisaetus floris) was a Critically Endangered endemic raptor species in Lesser Sunda Region, especially in East Nusa Tenggara. The lack of information and difficulties in reaching the Flores hawk-eagle's distribution area have caused difficulties in conservation efforts for this species. One of the efforts that could be made was by spatial modeling distribution of Flores hawk-eagle habitat in East Nusa Tenggara based on GIS. Using habitat distribution spatial modeling could predict the potential place where a species can live. Logistic regression was one of the methods applied in animal distribution spatial modeling, where this method was considered to have better accuracy. Through the analysis, it was found that the potential habitat for Flores hawk-eagle was 6390.48 km2 (22%), and the non-potential habitat was 22,459.59 km 2 (78%). The habitat factors that determine the distribution of the Flores hawk-eagle include slope, altitude, rice fields, plantation, forests, and shrubs. The availability of nesting trees and food for Flores Hawk-eagles may influence the distribution of existing habitats. The results of the distribution mapping of the Flores Hawk-eagle can be used as a reference in efforts to manage the habitat of the Flores hawk-eagle in East Nusa Tenggara.

Abstract

Marshlands and backswamps are among the threatened habitats in Indonesia, along with mangroves, particularly in Java due to area development and land conversion. Muara Gembong is one of the remaining wetlands in Java and serves as one of the last refuges for the bird community in wetlands, particularly mangrove and marsh-associated birds. We observed bird communities and collected eleven habitat variables in three habitats, namely mangrove, marsh, and fishpond, to see which variable affects bird abundance and diversity most. We found out that the total number of plant species, along with the number of tree, understory, and shrub species, were the strongest factors affecting bird diversity in Muara Gembong. Separate analysis in each habitat, however, reveals that different abiotic factors also strongly correlate with bird diversity. Vegetation correlates strongly with bird diversity in mangroves and marshes, while pH and turbidity play a strong role in bird diversity in fishponds.

Abstract

The Flores hawk-eagle (Nisaetus floris) is an endangered raptor endemic to the Lesser Sunda region and remains understudied, hindering effective conservation planning. This study investigates the species’ home range, habitat use, and threats at two active nesting sites in Ende District, Flores Island. Home range estimates varied between 8.439 km² (using minimum convex polygon/MCP) and 23.38 km² (using hypothetical-circular home range/HCHR) in Wolojita and from 6.385 km² (MCP) to 23.38 km² (HCHR) in Mbuli. Intensive use areas were relatively small, measuring 0.449 km² in Wolojita and 0.494 km² in Mbuli. Habitat use analysis revealed that in Wolojita, the eagles favored secondary forests, settlements, and shrublands, while in Mbuli, they primarily utilized grasslands and secondary forests, actively avoiding agricultural lands, rice fields, and areas near sulfuric rivers. Secondary forests appear to provide essential resources such as nesting trees and prey availability. However, competition with other raptor species, coupled with anthropogenic threats such as habitat degradation, land-use change, and persecution driven by livestock predation, poses significant risks to the species’ survival. Conservation should focus on preserving secondary forests, promoting sustainable land-use practices, and mitigating human-wildlife conflict to ensure the long-term viability of the population.

Abstract

The cattle egret (Bubulcus ibis) utilizing landfill sites for foraging is not a new or rare phenomenon. However, to date, there is no scientific data on the presence of cattle egrets in landfill areas on a national scale. This study aimed to determine the abundance dynamics of cattle egrets at the Jatibarang landfill. Data collection on individual count dynamics was carried out using the Concentration Count method. Initially, this method involved identifying strategic areas to facilitate counting individual birds in each Active Zone. Bird censuses were conducted from 06:00 to 18:00 WIB using hourly photographic documentation. Data on the dynamics of cattle egret abundance in each Active Zone were tabulated using Microsoft Excel 2016, and graphs were produced to show the average number of individuals during the study. The results showed that the abundance dynamics varied among Active Zones, influenced by the status of waste disposal activities, which affected the availability of abundant food. The distribution patterns and utilization levels of cattle egrets in the three Active Zones differed due to variations in waste conditions, influencing the number and types of insects (larvae and adults). Active Zone 1 was intensively used by cattle egrets, with numbers reaching between 140 and 1505 individuals.

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.

Abstract

Southern Cassowary (Casuarius casuarius) is  a seed disperser of North Australia and Southern Papua lowland forest ecosystem. Despite its dominant distribution in Southern Papua, there is a lack of information regarding its population and habitat characteristics. Due to its high sensitivity, the southern cassowary is rarely seen across the forest, yet the signs of its presence (feces and footprints) are abundant. This study analyzed the distributions, population, and habitat characteristics of the southern cassowary’s in Sota and Wanggo Resort, Wasur National Park, Southern Papua. Maximum Entropy results showed that its distribution focused on the northeastern area of Wanggo Resort and several points north of Sota Resort. Using fecal distance sampling, this study found that the southern cassowary population density in Wasur National Park areas was 0.8 ind/km2, primarily in lowland forests. The area corresponds to the variables that most influence the southern cassowary, which are NDVI, annual precipitation, and distance to the road. These findings underscore the urgency of local stakeholders to pay specific attention to lowland forests in Wasur National Park.
