ABSTRACT Way Pegadungan wetlands is a wetland closure difference between the two riparian communities. One of the wetlands is converted into paddies fields, while the other is a natural wetland which are still overgrown with trees. To determine diversity differences in bird species between two wetlands research communities, the point count method (IPA) and line transects were used. Observations made by the stationary point count and record the birds found. Each community was taken 6 points count and observed for 3 days. Research encountered 41 species of birds included in the 17 families with a total of 796 individual in paddies fields and 46 birds species with total of 655 individuals from 17 families of individuals in natural wetlands. Natural wetlands diversity index was 3.44 with equality index of 0.90, this value is higher than the wetlands changed into paddies fields with a diversity index of 2.91, and in a stable condition with equality index of 0.78. Both wetlands communities have the same identical species approach (IS = 1) with a similarity index of 0.73. Key words: birds, diversity, wetlands, Way Pegadungan

The study was conducted in April 2017, located along the Wailawa watercourses, Tawiri Village, Ambon. The method applied in these studies were Point Count, while data analysis using Shannon-Wiener Diversity Index, Evenness Index, Domination Index, Similarity Index, and Guild Composition. The results showed that the number of bird species found along Wailawa watercourse were 28 species of 25 genera, 17 families, and 8 orders. The diversity of bird species is moderate (H ‘= 2,54). The bird species similarity analysis resulted in three bird communities, including: (1) bird communities in mangrove forest, estuaries with grass vegetation, (2) bird communities in garden and settlement habitats, and (3) bird communities in mixed forest habitat. Mangrove forest and estuaries have the highest species similarities (0,63). Estuaries and mix gardens have the lowest bird similarities (0,05). Bird communities in mangrove forests and estuaries are heterogeneous because they have more species with a more equitable distribution of species abundance, while in other habitat, their are homogenous because of relatively have a low species diversity with uneven distribution of species abundance.Penelitian ini bertujuan menganalisis komunitas burung, meliputi kekayaan jenis, keanekaragaman jenis, kelimpahan relatif, kemerataan jenis, foraging guild, serta kesamaan jenis.

Abstract. Riefani MK, Soendjoto MA. 2021. Birds in the west coast of South Kalimantan, Indonesia. Biodiversitas 22: 278-287. There is no comprehensive data on birds in the west coast of South Kalimantan, yet the areas are pressured by human activities, especially the rapidly growing tourism. This study aimed to investigate the diversity of bird species that occurred in the west coast of South Kalimantan and to compare the similarities of bird communities across four villages used as the sampling sites, i.e. Sungai Rasau, Sungai Bakau, Tabanio, and Pagatan Besar. Transect method combined with concentration count method were used to record diurnal bird species and number of individuals in five replications from April to September 2020. The observation area was 100 m from the shoreline toward the sea and 400 m from the shoreline toward the inland along 2 km with observation time was 07.00-11.00 and 16.00-19.00. Shannon Wienner species diversity index (H'), a Dice community similarity index based on the presence or absence of species (ISD), and a community similarity index (modification) based on the number of individuals per species (ISM) were analyzed. In total, there are 101 bird species recorded belonging to 41 families with Sungai Bakau Village has the highest number of species (81 species), while Pagatan Besar Village is the lowest (62 species). Thirty-four species are categorized as waterbirds. Twenty-three species are categorized as migratory birds. In terms of diversity index from highest to lowest are Sungai Bakau (4.04), Sungai Rasau (3.95), Pagatan Besar (3.65), and Tabanio (3.48). The similarity of the ISD community ranges from 0.74-0.84, while the ISM ranges from 0.73-0.90. One case (Sungai Bakau - Tabanio) shows that community similarity based on the number of individuals per species is smaller than based on the presence or absence of species. Based on the protection status following Indonesian government regulation, most (84.16%) birds are categorized as unprotected, while based on the conservation status of IUCN, the majority (91.09%) are Least Concern. The results of this study can be used as baseline information for sustainable management of the area in various aspects, including future research (such as on pest and disease control), tourism (such as bird watching), and education (such as field guide).

Avifauna is one of the biodiversity that has a role in the ecosystem, namely as a seed spreader, helps pollination, and as an environmental bioindicator. The Elephant Training Center (PLG) is not only a conservation centre for Sumatran elephants but also serves as a habitat and preserves the diversity of all animals including avifauna species. One form of conservation efforts towards avifauna is to record the diversity of the avifauna species present in that location. This study aims to determine the diversity of bird species found in the Way Kambas National Park PLG. The study was conducted using the point count method at three observation locations: garden area, grassland, and swamp area with three repetitions. The results of the study found 33 species from 21 families (727 individuals) with moderate species diversity values (1 <H '<3). The diversity of bird species affects the existence of some species in a habitat so that it affects the quality of habitat and plays an important role as a bioindicator in an ecosystem. Bird conservation efforts need to be carried out and supported by all parties to maintain the existence of birds in their natural habitat.Key words: Avifauna, diversity, conservation, national park, elephant training center.

The investigation of species diversity and abundance of birds in Lake Hora Arsedi Bishoftu town was conducted from September 2018 to July 2019. The aim of the study was to assess the diversity and abundance of bird species in Lake Hora Arsedi at Bishoftu town. Point count method was used to investigate the abundance of birds. Observation was conducted periodically walking along the study area early in the morning and late in the afternoon. Different diversity indices and statistical methods (Chi-square test and correlation) were used to analyze data collected during the field survey. Abundance of birds, their richness and evenness as well as birds` diversity recording were made. A total of 14 bird species grouped under 7 orders and 11 families were recorded. The month February had the lowest species diversity (H’= 0.33), species evenness (E = 0.13) and species richness (12). The highest species diversity, evenness and richness were recorded in March and April (H’=0.35), (E = 0.35) and (S = 14), respectively. Variation in abundance of birds was statistically significant between months. Abundance score of frequency of bird species was high during rainy season and uncommon are high during small rainy seasons using encounter rate. Lake Hora Arsedi has a number of natural and human induced bird attractant features. The area possesses favorable places for birds to nest, rest, roost and a good access to food as well as water resources. The study recommends the maintenance of bird watching records to monitor the effectiveness of management and to ensure early detection of any impact on bird numbers or behavior; conservation of Lake Hora Arsedi, its surroundings and making it free from human interference will enable us to conserve these valuable bird species. Hence, conservation measures by wildlife conservation authority and other concerned agencies are important to safeguard these species in the area.

Abstract The Mandalika Special Economic Zone (SEZ) was designated as a tourist area in 2015. The development of the Mandalika area directly impacts the sustainability, diversity of species, especially birds that make mangroves their habitat. The study aims to investigate the value of bird species diversity in mangrove habitats as bioindicators. Furthermore, the research has been carried out for three months, from March to May 2021. Research data collection uses the roaming method, and data analysis uses bird community structure analysis (Diversity Index). In this study, 33 species of birds were found. Furthermore, it was found that six species of birds are protected wildlife. In addition, 16 are migratory birds, and 27 are Least Concern (LC) bird species; four species have Near Threatened (NT) status. Meanwhile, the Index of bird community structure is H’ 2.7, uniformity E 0.8, and dominance C 0.9. The value of the bird community structure in the Mandalika SEZ shows the condition of mangrove habitat in the moderate damage category. Therefore, there needs to be an effort to preserve mangroves involving the community, government, and Indonesia Tourism Development Corporation (ITDC) area managers.

Avifauna is one of the animals that is easily found in various places, and is one indicator of environmental quality. Avifauna has the ability to spread seeds, help pollinate, natural predators of other animals, and others. This study aims to record the diversity of diurnal avifauna in area Mempawah Mangrove Park and its surroundings in Pasir Village Mempawah Hilir Subdistrict, Mempawah district. The research method used the Point count method, whose observation points are obtained by Purposive sampling, carried out on 9 July-9 August 2018. The results of observations were 35 species of avifauna consisting of 24 families which were divided into three habitats, in the mangrove habitat there were 18 species and 15 families, mixed garden contained 22 species and 18 families, and rice field contained 17 species and 11 families. The dominance index in the mangrove habitat is C = 0.40, mixed garden is C = 0.10 and rice is C = 0.13, indicates that no species dominates the other species, meaning the role of the avifauna species found in all three same habitat. Diversity index shows that mixed garden habitat has a higher species diversity with () = 2.66, mangrove habitat is () = 2.43 and a rice field habitat is () = 2.40, indicates that the three habitats have diversity with moderately criteria. Evenness index in mangrove habitat is (E) = 0.84, in mixed garden habitat is (E) = 0.85 and a rice field habitat is (E) = 0.85, indicates the three habitats the abundance includes evenly distributed or included in a stable community. The highest similarity index of avifauna species is between mangrove habitat and mixed garden with a percentage of 53.58%, rice field habitat with a garden with a percentage of 53.19%, and mangrove habitat with rice fields with a percentage of 38.49%. The highest similarity was between.Keywords: Avifauna, Diversity, Mempawah Mangrove Park

Using the point count method, linear mixed models, Shannon’s diversity index, and Bray-Curtis cluster analysis, we conducted a study of the effect of urban fabric layout on bird diversity and distribution in northern Rwanda. The results showed a significant effect of city landscapes on bird richness and relative abundance; residential neighborhoods, institutional grounds, and informal settlements had the highest species diversity in comparison to other microlandscape types. Riversides were characterized by specialized bird species, commonly known to be restricted to wetland environments. Built-up areas and open field landscapes had comparable results. One Albertine Rift endemic bird species, the Ruwenzori Double-collared Sunbird (Cinnyris stuhlmanni), was recorded. Three migratory birds were found in Musanze city for the first time: the Common Sandpiper (Actitis hypoleucos), the Spotted Flycatcher (Muscicapa striata), and the Willow Warbler (Phylloscopus trochilus). Two bird species have not been previously reported in Rwanda: the Garden Warbler (Sylvia borin) and the Lesser Spotted Eagle (Aquila pomarina). The implications of this study are particularly relevant to urban decision makers who should consider the existence of a great diversity of avian fauna when developing and implementing master plans, especially when villages and cities are in proximity of protected areas or natural reserves.
