The study (2007-08) was carried out in Phewa Lake which is one of the largest lake systems in Nepal to evaluate seasonal diversity and population status of waterbirds. A total of 39 waterbird species belonging to 17 families of 5 orders was recorded. The highest number of species (31 species) was found in December and January. Winter was the most diverged season in terms of number of species (35 species) and summer and autumn by 17 species. January had the highest (1584) and September the lowest (345) waterbird population. Out of 39 species, 15 species were winter visitors, 10 resident, and 4 rare winter visitor. The highest diversity ( H =2.6228) was found in February and lowest ( H =1.2014) in June. The value of evenness (Jacob's coefficient) was higher (0.8485) in February and lowest (0.4555) in June. During June, 69.92% (616 individuals) of the total population (881) constituted only Cattle Egret. The dominancy was found highest (C=0.5058) in June and lowest (C=0.1020) in February. The bird communities of summer and autumn were more similar (S=0.7059) than the summer and winter (S=0.5). The fluctuation in number of individuals of bird species was found unrelated to seasons (months) (F=1.71, df = 8, 342, P ≤ 0.05). The species richness was found different in different seasons (months) (Χ2=29.34, df = 8, P ≤ 0.05). Detail study of bird diversity and population status with periodic monitoring in Phewa Lake is recommended for their conservation and management as a whole.

Abstract. Ramlah S, Santosa Y, Santoso N, Rushayati SB. 2021. The variation of bird diversity in various oil palm land cover in North Mamuju, West Sulawesi, Indonesia. Biodiversitas 22: 3068-3074. The development of oil palm plantations provides various positive impacts. On the other hand, this development is suspected to bring negative impacts on biodiversity, especially reducing bird species diversity. Based on the other research, well-managed oil palm plantations that maintain high conservation value areas have high species diversity. This study aimed to identify bird species diversity in different types of oil palm plantation land covers in North Mamuju. Data observation of bird species was performed using the transect method. There were 4 transects on each land cover. The results of this study showed that the young oil palm area had a high index of diversity and species richness. The high species diversity in the young palm area was caused by habitat variations. There was a water flow that provides more feed sources. The distance between the young oil palm area and secondary forest area affected the number of species, species richness and diversity of bird species. The category of insectivore guild which included aerial insectivores and insectivores was the dominant guild in all types of land cover, both in the number of species and the number of individual abundances.

A rapid bird survey was done in a small conservation area of industrial timber concession of PT BMH (Bumi Mekar Hijau), namely KPPN (Kawasan Pelestarian Plasma Nutfah), South Sumatra Province. The area has 448 ha, dominated by degraded secondary swamp forest surrounded by Acacia plantation. Three survey methods were applied to assess bird diversity in this area: transect line, mist-netting and audio-visual station recording. A total of 36 species was recorded during survey. Among three methods applied, transect line is the most effective method to detect more bird species (29 species), followed by audio-visual station recording (26 species) and mist-netting (three species). There are eight species which protected by Indonesian law and two birds are listed as Near Threatened (NT) by International Union for Conservation of Nature or IUCN. Although number of species birds recorded are not significance, but this area still support habitat for various birds diversity, and the forest remaining should be well-managed to support its conservation goals.

Penelitian ini bertujuan untuk mengetahui respon komunitas burung terhadap keberadaan Pembangkit Listrik Tenaga Panas Bumi Kamojang. Kami membandingkan keanekaragaman dan kekayaan jenis burung pada lokasi yang terdampak (DL) dan tidak terdampak (TL) di Wilayah Kerja Panas Bumi Kamojang, Cagar Alam Kamojang dan Taman Wisata Alam Kamojang di Kabupaten Bandung Provinsi Jawa Barat. Lokasi yang terdampak berada di sekitar sumur produksi atau pembangkit listrik tenaga panas bumi (30 sampel) sedangkan lokasi yang tidak terdampak adalah dengan jarak 3.000 m sampai 9.000 m dari fasilitas tersebut (42 sampel). Pengumpulan data dilakukan selama dua musim; musim kemarau dan penghujan (2015-2016). Kami mengumpulkan data komunitas burung dan data habitat dengan metode point count yang ditempatkan secara sistematis di setiap lokasi. Kami menemukan 124 spesies burung yang terdiri dari 35 famili dan 16 spesies di antaranya adalah burung endemik di Pulau Jawa. Dua puluh tiga spesies dilindungi oleh undang-undang di Indonesia, sembilan spesies termasuk dalam daftar lampiran CITES dan lima spesies masuk dalam Daftar Merah Spesies Terancam IUCN tahun 2017. Terdapat perbedaan respon antara komunitas burung di lokasi terdampak dan tidak terdampak yang ditunjukkan dengan perbedaan rata-rata jumlah spesies, jumlah individu masing-masing spesies, indeks keanekaragaman ShannonWiener. Lokasi tidak terdampak memiliki nilai lebih tinggi pada parameter ini dibanding lokasi yang terkena dampak. Demikian juga, jumlah spesies, jumlah individu vegetasi dan indeks keanekaragaman hayati ShannonWiener pada lokasi TL memiliki nilai rata-rata lebih tinggi daripada lokasi DL. Hal ini membuktikan bahwa meskipun panas bumi dianggap sebagai energi ramah lingkungan namun dalam penggunaannya masih berdampak pada keanekaragaman hayati di sekitarnya terutama untuk jenis burung. Response of Bird Community to Kamojang Geothermal Power Plant, Bandung, West JavaAbstractThis study aimed to investigate the response of bird communities on the presence of geothermal power plant of Kamojang. We compared the bird diversity and richness of affected (DL) and not affected (TL) in Kamojang Geothermal Working Area, Kamojang Nature Reserve and Kamojang Nature Park in Bandung regency of West Java Province. The affected sites were surrounding production wells or geothermal power plants (30 samples) whereas not affected sites were with distance of 3,000 m to 9,000 m from those facilities (42 samples). The data collection was carried out during two seasons; dry and rainy season in (2015-2016). In each site, we collected bird community data and habitat data with the point count method which was placed systematically on each sites. We found 124 birds species belongs to 35 families with 16 endemic species in Java Island. Twenty three species are protected by Indonesian law, with nine species are in the CITES appendix list and five species are listed in the IUCN Red List of Threatened Species of 2017. There was a difference of responses between bird communities in the affected and not affected sites which is indicated by differences in the mean number of species, number of individuals in each species, and Shannon-Wiener's diversity index. The not affected sites had higher value on these parameters than the affected sites. Similarly, number of species, number of individual vegetation, and Shannon-Wiener biodiversity index in TL sites had higher mean values than DL sites. This proves that although geothermal is considered as environmentally friendly energy but in its utilization it still has an impact on the surrounding biodiversity especially for bird species.

One year survey conducted in and around Bhindawas bird sanctuary in district Jhajjar, Haryana (India) from January, 2015 to December, 2015; revealed a total of 104 bird species belonging to 15 orders and 39 families. Of these, 67 bird species were resident, 32 species were winter migrants and only 5 species were summer migrants. Based on their frequency of sighting, 33 bird species were categorized as Abundant, 27 species as Common, 32 species as Uncommon and 12 species as Rare. Maximum number of species belonged to order Passeriformes and least number of species belonged to order Podicipediformes and Strigiformes. Among the recorded birds, 4 species namely, Darter, Anhinga melanogaster; Black-necked Stork, Ephippiorhynchus asiaticus; Oriental White Ibis, Threskiornis melanocephalus; and Alexandrine Parakeet, Psittacula eupatria were near threatened and 2 species namely, Common, Pochard, Aythya ferina and Sarus Crane, Grus antigone were vulnerable. In early 1990s, a study was conducted on Bhindawas bird sanctuary and thereafter, a great deal of infrastructure, development and urbani-zation has occurred. However, scanty information is available on the avian diversity periodic monitoring of Bhinda-was bird sanctuary, Haryana. Therefore, present study was planned to monitor and document the avian species.

Mangroves are of great ecological importance that provide multiple ecosystem services, shelter, and habitat for many threatened waterbird species.  The mangroves of the Menabe Antimena Protected Area (MANAP) in western Madagascar are among the most extensive remaining on the island.  The remaining dryland forests of the MANAP have been subjected to immense deforestation in recent years.  Although remote sensing studies indicate that the mangrove forest loss is considerably lower than the dryland forest loss, little is known about the mangroves’ degradation status.  Furthermore, detailed information on bird diversity and numbers is scattered, and previous surveys focused on northern parts of the MANAP, recently designated as the Wetlands of the Tsiribihina RAMSAR site.  This study aims to assess bird diversity and abundance, as well as the status of mangroves in the MANAP. We conducted a rapid survey using direct observations at three sites along the coastal regions of the MANAP from 24 Sep–2 Oct 2019.  We recorded 71 species of birds in the mangroves and coastal wetlands.  High numbers of individuals were counted for several species.  Numbers of the Madagascar Plover Charadrius thoracicus and the Madagascar Teal Anas bernieri fulfill criteria for important bird areas at single survey sites and the site is likely to be of importance for Madagascar Sacred Ibis Threskiornis bernieri; these three species are all globally threatened.  Mangrove degradation is still limited, but numerous threats to mangroves are present.  Our results highlight the importance of the mangroves of the MANAP for several endemic bird species in Madagascar.  We provide recommendations for conservation management and future research.

A bird survey is carried out  in lakes of Coimbatore (kumarasamy and singanallur) to examine the diversity and richness distribution of bird species in wetland region. This survey was taken from july 2018 to December 2018 to suitably access the bird diversity. A total number of 50 species from 13 orders and 34 families were recorded. The month of October and November maximum numbers of birds were identified. Pelicaniformes contributed maximum number of species. Finally, least number of birds recorded in Gruiformes, Strigiformes, Psittaciformes, Gariformes, Columbiformes and Podicipitiformes. Maximum bird species were recorded in Singanallur Lake and minimum in Kumarasamy Lake. The study revealed that Kumarasamy and Singanallur Lake acts as a refuge site for many water birds. Hence it is recommended that protection of the wetland from the human disturbance is of urgent need.    Key words: Kumarasamy, Threatened, Gariformes

The diversity and population of birds was studied from January, 2011 to December, 2011, once a week regularly. Altogether fifteen species of wetland birds were recorded from Tengra and Budhi rivers. Maximum species were recorded in January and minimum in July and August. Out of total bird species 40% were migratory, 46.67 % were resident, and 13.33 % were winter visitors. On the basis of abundance, there were 46.67% scarce, 33.33% fairly common and 20% common. On the basis of their population status, maximum number belonged to Ardeola grayii species and minimum in Leptoptilos javanicus species. Maximum species of the birds belonged to family Ardeidae. According to statistical analysis, the resident bird were more diversed then migrant and winter visitor respectively. Similarly, resident birds were much evenly distributed then winter visitors and migrant respectively. The study revealed decreasing trend of bird species from previous period. The conversion of wetland into agricultural land and plotting programmes were the main causes to decline the bird species.

Bird survey was conducted in Phulchoki hill during two different seasons in January 2018 and April 2018. The objective of the study was to identify seasonal avian diversity, and to determine relative abundance and species richness. Fixed radius point- count method was used to evaluate the bird diversity and their number. Shannon-Weiner Diversity Index was used to calculate the diversity of species during two different seasons. A total of 78 species of birds belonging to 7 orders and 24 families were recorded. Passeriformes was the most dominant order with 58 species and Sylvidae was the most dominant family with 14 species. 59 bird species were recorded in winter and 50 in spring seasons. The analysis of data on residential status revealed that 64 species were residents, 10 species winter visitors and 4 species summer visitors. The relative abundance of species was Very Common (n= 16), Common (n= 38), Uncommon (n= 9) and Rare (n= 15). Higher Shannon- Weiner Diversity Index (H'= 1.488) was recorded during the winter season and low during the spring season (H'= 1.169). Evenness index showed that birds were evenly distributed in winter season (E= 0.253) than spring season (E= 0.207). Maximum birds were seen in Mining area during both winter and spring season and minimum birds in the bus park area of Phulchoki due to habitat destruction and human disturbances.

Mangrove forests have many functions, one of which is a habitat for various water birds and birds. Birds make mangroves a habitat to find food, breed, or just rest. Birds that can be found in mangrove forests can be birds that live and nest in mangrove forests and birds that come from other habitats that only occasionally visit mangroves to find food or rest. The research method used is the Point Count method, where the observation technique is carried out at a point, and the observations are carried out over a certain period. The number of bird species recorded in the mangrove area of ​​Passo Village was 11 species from 9 genera, seven families, and seven orders. The average number of individuals recorded during the research activity was 197 individuals. 72.73% of the composition of bird species in the mangrove area of ​​Passo Village are waterbird species, including four orders from a total of 7 charges, and four families from a total of 7 families, and six genera from a total of 9 genera; while the other 27.27% are terrestrial bird species.
