Abstract The present study attempts to assess the composition, abundance and diversity of avifauna with respect to their habitat in and around the Purbasthali wetland, based on both primary data collected through the point count method during 2017–2019 and literature data. Among the total 77 species (encompassing 10 orders and 19 families), 39 species are migrants, 18 are rare and 24 species show declining global trend. According to their habitat, they are sub-divided into three categories i.e. waterfowls (live in open water, 20 species), waders (live in bank areas/water edge area, 45 species) and wetland associated (live in nearby trees, 12 species). The Shannon-Wiener Diversity Index (H’) and the Evenness Index (E’) are used to examine the diversity within and between the habitats. The result reveals higher diversity and evenness of the waders in comparison to others. The maximum diversity (H′=3.02) and evenness (E′=0.79) has been recorded for the waders in 2019, whereas the least values (H′=1.02, E′=0.34) have been found in 2016 for the waterfowls. Relative Diversity Index affirms the dominance of the Anatidae family. The birds of the area have now been seriously threatened by human intervention.

There exists limited information on biodiversity including avifaunal diversity and habitat condition in community forests (CF) of Nepal; thus we aimed to fulfill such gaps in Tibrekot CF of Kaski district. We used the point count method for assessing bird diversity and laid out a circular plot size of radius 5-m within 15-m distance from each point count station for recording the biophysical habitat characteristics. Bird species’ diversity, richness and evenness were calculated using popular indexes and General Linear Model (GLM) was used to test the respective effect of various biophysical factors associated with the richness of bird species. In total, 166 (summer 122, winter 125) bird species were recorded in 46 sample plots. The Shannon-Wiener diversity index was calculated as 3.99 and 4.09, Margalef’s richness index as 16.84 and 17.53 and Pielou’s evenness index as 0.83 and 0.84 for summer and winter, respectively. The influencing factors for richness of bird species were season (χ21, 90= 112.21; P= 0.016) with higher richness in the summer season and low vegetation cover (χ21, 89= 113.88; P= 0.0064) with higher richness in lower percentage cover. Thus, community managed forest should be protected as it has a significant role in increasing bird diversity, which has potential for attracting avifaunal tourism for the benefit of the local communities.

Greenspaces and forest trees contribute to a number of environmental functions in urban environments, such as the survival of urban-dwelling species (e.g., bird species). This paper analyzes the relationship between greenspace characteristics (structural and spatial attributes) and the diversity of avian ecology species. This provides research findings coming from two studies conducted in Italy. Using point-count method, a quantification was done of the abundance and diversity of bird species in a number of greenspaces having different structural attributes (e.g., vegetation type, tree height) and spatial characteristics (e.g., location, connectivity). Results showed positive correlations between greenspaces with a more diverse and mature forest vegetation and the number of specimens and species observed in the two studies. A positive correlation appeared also between distance to the city centre and richness and abundance of bird species. Finally, we discuss some of the main implications for enhancing the functional attributes of greenspaces by using avian ecological indicators to inform ecologically sound urban planning and design.

Informasi mengenai keanekaragaman hayati di ITERA sendiri belum banyak diteliti, salah satunya adalah keanekaragaman burung. Burung merupakan hewan besar yang cukup sensitif dengan perubahan lingkungan. Penelitian ini dilakukan untuk mendapatkan data mengenai keanekaragaman burung di ITERA untuk memberikan informasi dasar. Metode yang digunakan adalah teknik point count, diterapkan pada lima stasiun utama yang dipilih berdasarkan pusat aktivitas pembangunan. Analisis yang digunakan adalah indeks keanekaragaman, kemerataan, juga kelimpahan. Selain itu, status konservasi dan tipe pakan jenis burung dianalisis menggunakan data sekunder. Hasil penelitian menunjukkan terdapat 19 jenis burung dari 16 famili. Keanekaragaman jenis burung berdasarkan indeks Shannon-Wiener tergolong sedang dan kemerataan jenis merata. Dari kategori kelimpahan yang digunakan terdapat dua jenis burung yang umum ditemukan. Bersumber pada PP No. 7 tahun 1999, terdapat empat jenis burung di ITERA yang termasuk ke dalam kategori dilindungi dan satu jenis termasuk kategori Appendix II di CITES. Feeding guild burung di ITERA didominasi tipe omnivora dan insektivora. AbstractInstitut Teknologi Sumatera (ITERA) campus area is undergoing rapid physical development, such as the construction of lecture buildings, laboratories, dormitories, as well as reservoirs for water sources. Information on biodiversity in ITERA has not much studied, one of which is bird diversity. Birds are large animals that are quite sensitive to environmental changes. This study aims to obtain data on bird diversity at ITERA to provide the baseline information. The method used is a point count technique, applied to five main stations selected based on the center of development activities. The analysis used is an index of diversity, evenness, and abundance. Besides, the conservation status and feed type of bird species were analyzed using secondary data. The results showed that there were 19 species of birds from 16 families. The Shannon-Wiener diversity index classified the bird community as a moderate, and the community evenness index was stable. From the abundance category, two types of birds commonly found. Based on PP No. 7 of 1999, there are four species of birds in ITERA, which included in the protected category and one species, including the Appendix II category in CITES. Omnivorous and insectivorous types dominate bird guild feeding in ITERA.

Point Count Method

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.

The Impact

The present study attempts to assess the impact of human intervention on the population, distribution, and habitat perspectives of the water birds found in and around Chariganga and Arpara ‘Beel’ wetlands, leftover channels of the River Bhagirathi. The point count method was adopted during field surveys conducted from April 2019 to March 2020. These wetlands are the natural habitats for 37 species of wetland birds belonging to 18 families and 11 orders, of which 26 species are residents, three are summer migrants, and eight are winter immigrants. The wetlands also harbour 10 bird species whose population is globally declining over the last few decades. Relative Diversity index unveils that among waterfowls Ardeidae is the dominant family. Species richness reaches its peak in winter, and is least during the monsoon. Empirical observation documented one Vulnerable (Greater Adjutant) and one Near Threatened (Black-Headed Ibis) species residing on the banks and adjoining paddy fields. Indiscriminate extraction of wetland products by local people, along with agricultural expansion towards the waterfront of the wetlands, has deteriorated the health of those wetlands and threatened the existence of waterbirds, especially shorebirds. Populations of 22 species living in water edge areas has changed conspicuously owing to cultural and economic activities of neighboring human groups. We suggest improving the ecological balance of the wetlands and restraining further degradation through proper management to preserve avian diversity.

Malaysia is characterized by a variety of habitats such as forests, clearings, thickets, and cropland that attract various species of birds. This study examined the bird community in terms of richness and diversity at oil palm plantations habitat. The abundance of birds was determined by using distance sampling point count method. A total of 2722 birds belonging to 38 families representing 86 species of birds were detected. Diversity analysis indicates that the species of birds in the oil palm plantation at Sungai Pelek is more diverse (Shannon-Wiener Diversity Index H; 3.52) and richness (Margalef’s Richness Index R1; 10.2) than oil palm plantation in Teluk Panglima Garang-Pulau Carey and Banting-Jenjarum. However, the species of birds in the oil palm plantations at Teluk Panglima Garang-Pulau Carey and Banting-Jenjarum show higher evenness (Pielou’s Evenness Index E; 0.82) compared with oil palm plantations in Sungai Pelek. The results of this study indicate that the species composition and distribution of the avian species in the oil palm plantations are affected by habitat characterization of that particular area and its vicinity.

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. Penelitian dilakukan pada bulan April 2017, berlokasi di sepanjang Anak Sungai Wailawa, Desa Tawiri, Kota Ambon. Metode pengambilan data adalah metode point count, sedangkan analisis data menggunakan Indeks Keanekaragaman Shannon-Wiener, Indeks Kemerataan Jenis Evennes, Indeks Dominasi Jenis, Indeks Kesamaan Jenis, dan Foraging guild. Hasil penelitian menunjukkan jumlah jenis burung yang ditemukan sebanyak 28 jenis dari 25 genus, 17 famili, dan 8 ordo. Keanekaragaman jenis burung tergolong sedang (H’ = 2,54). Hasil analisis tingkat kesamaan komunitas menghasilkan tiga komunitas burung, meliputi : (1) komunitas burung di hutan mangrove-muara sungai bervegetasi rumput, (2) komunitas burung di kebun dan permukiman, serta (3) komunitas burung di kebun campur. Hutan mangrove dan muara sungai memiliki kesamaan jenis burung tertinggi, yakni 0,63. Muara sungai dan kebun campur memiliki kesamaan jenis burung terendah, yakni 0,05. Komunitas burung di hutan mangrove dan muara sungai adalah komunitas heterogen karena memiliki lebih banyak spesies dengan distribusi kelimpahan spesies yang lebih merata, sedangkan komunitas burung pada tipe habitat lainnya adalah komunitas homogen karena keragaman jenis relatif rendah dan distribusi kelimpahan spesies tidak merata.
