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

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.

Environmental protection programs exert strong effects on vegetation and plant conservation; however, few researchers have dealt with the impacts of environmental protection programs on wildlife recovery. We compared the spatial changes in avian species distributions caused by these environmental restoration programs for 63 national key protected bird species by overlaying GIS layers to examine the effects of environmental protection on bird diversity since 2000 in Beijing, China. Generally, these species congregated in areas away from human disturbance and around wetlands, city parks, and woodlands. Class One protected birds appeared to be expanding their ranges although they were sparsely distributed. Two Class One species appeared new to the area after 2000. Several Class Two protected species were also enlarging their ranges and one Class Two species appeared new to the area. The results reveal that the ranges of bird species as well as species diversity of the national key protected birds are increasing as wetlands recover and vegetation conditions improve in the vicinity of Beijing.

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.

With the lack of baseline information on avifauna within Bicol University and the adjacent forest fragment, this research aimed to identify bird species and compare their presence between an urbanized and forest areas. Avian diversity was documented within the Kalikasan Park and Bicol University Main Campus adjacent ecosystems, representing a forest fragment and semi-urbanized ecosystems, respectively. Bird survey was carried out through point count method. Identification was aided by existing taxonomic keys. A total of 44 species were recorded with eleven as Philippine endemics. Lonchura malacca(Chestnut Munia) and Aplonis panayensis (Asian Glossy Starling) were among the most frequently sighted. Bird species sighted was higher in the forest fragment as compared with the main campus area. The study recommends that Bicol University Main campus be transformed into an avian buffer and safe zone for the protection and conservation of these species and to provide policies to maintain high bird diversity.

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.

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.

AbstractHuman alteration of landscapes leads to attrition of biodiversity. Recommendations for maximizing retention of species richness typically focus on protection and preservation of large habitat patches. Despite a century of protection from human disturbance, 27% of the 228 bird species initially detected on Barro Colorado Island (BCI), Panama, a large hilltop forest fragment isolated by waters of Gatun Lake, are now absent. Lost species were more likely to be initially uncommon and terrestrial insectivores. Analyses of the regional avifauna, exhaustively inventoried and mapped across 24 subregions, identified strong geographical discontinuities in species distributions associated with a steep transisthmian rainfall gradient. Having lost mostly species preferring humid forests, the BCI species assemblage continues to shift from one originally typical of wetter forests toward one now resembling bird communities in drier forests. Even when habitat remnants are large and protected for 100 years, altered habitat characteristics resulting from isolation produce non-random loss of species linked with their commonness, dietary preferences and subtle climatic sensitivities.

Barekot rural municipality of Jajarkot district is an Important Bird Areas (IBAs) in Western Nepal. In recent years, illegal hunting and trapping-related cases have increased in this area. Additionally, a hydropower project with a capacity of 410 MW is being constructed within Barekot. The present study aims to update the preliminary checklist of birds and identify the underlying threats to the bird population in this region. Bird survey was conducted in four monitoring blocks of Barekot during the late winter of 2021. Also, a series of consultation meetings and interviews with the local stakeholders were organized to collect information regarding the extant threats. This study revealed eighty-seven bird species of 10 orders and 34 families. Birds most commonly recorded from the family Muscicapidae and order Passeriformes. Among the total recorded species, two species are listed in the IUCN Red List of Nationally Vulnerable Category. Similarly, five species were listed on CITES Appendix II and one species on CITES Appendix I. Approximately 82% of total bird species were of resident type. Despite a decline in bird diversity, Barekot’s unique geographical location still makes it an important IBA in Nepal. Bird numbers have plummeted due to human intrusion and disturbance, and natural system modifications. Based on our findings, we recommend landscape-level research, on the impacts of hydropower projects, roads, poaching, and impacts of the Covid-19 pandemic. Similarly, future conservation efforts should also emphasize preventing habitat fragmentation and raising public awareness. Keywords: Avian community; Bird checklist; Important Bird Area; Threats
