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.

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.

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.

AbstractAn estimated 19% of the world's 9,856 extant bird species are migratory, including some 1,600 species of land- and waterbirds. In 2008, 11% of migratory land- and waterbirds were classed by BirdLife International as threatened or near-threatened on the IUCN Red List. Red List indices show that these migrants have become more threatened since 1988, with 33 species deteriorating and just six improving in status. There is also increasing evidence of regional declines. Population trend data show that more Nearctic–Neotropical migrants have declined than increased in North America since the 1980s, and more Palearctic–Afrotropical migrants breeding in Europe declined than increased during 1970–2000. Reviews of the status of migratory raptors show unfavourable conservation status for 51% of species in the African–Eurasian region (in 2005), and 33% of species in Central, South and East Asia (in 2007). Land-use change owing to agriculture is the most frequently cited threat affecting nearly 80% of all threatened and near-threatened species. However, while agricultural intensification on the breeding grounds is often proposed as the major driver of declines in Palearctic–Afrotropical migrants, some species appear to be limited by the quantity and quality of available habitat in non-breeding areas, notably the drylands of tropical Africa. Forest fragmentation in breeding areas has contributed to the declines of Nearctic–Neotropical migrants with deforestation in non-breeding areas another possible factor. Infrastructure development including wind turbines, cables, towers and masts can also be a threat. Over-harvesting and persecution remain serious threats, particularly at key migration locations. Climate change is affecting birds already, is expected to exacerbate all these pressures, and may also increase competition between migratory and non-migratory species. The conservation of migratory birds thus requires a multitude of approaches. Many migratory birds require effective management of their critical sites, and Important Bird Areas (IBAs) provide an important foundation for such action; however to function effectively in conserving migratory species, IBAs need to be protected and the coherence of the network requires regular review. Since many migratory species (c. 55%) are widely dispersed across their breeding or non-breeding ranges, it is essential to address the human-induced changes at the wider landscape scale, a very considerable challenge. Efforts to conserve migratory birds in one part of the range are less effective if unaddressed threats are reducing these species' populations and habitats elsewhere. International collaboration and coordinated action along migration flyways as a whole are thus key elements in any strategy for the conservation of migratory birds.

The present study deals with the observation of avifauna in the Natural habitat and their adjoining areas of Harbhajwala in Dehradun, Uttarakhand. The study was carried out between December 2018 to October 2020. We observed 114 bird species, belonging to 50 families during the study period. Out of these 97 residents and 19 winters, migratory species were identified. The percentage of resident and winter visitor avian species was found to be 84% and 16%. Then the maximum number of species recorded from the family Muscicapidae. During the observation, we observed the Egyptian Vulture and Alexandrine Parakeet as Endangered and near-threatened species respectively according to IUCN. The presence of threatened species indicates the more conservation efforts are needed in the study area.

Avian diversity of Tilyar Lake (28.883–28.879 0N & 76.637 –76.634 0E)  located on the eastern outskirts of Rohtak, Haryana was conducted from May 2017 to April 2018.  A total of 73 avian species belonging to 62 genera and 31 families under 15 orders was observed. Order Passeriformes with 21 species in 12 families dominated the avifauna whereas orders Bucerotiformes, Podicipediformes, and Psittaciformes were poorly represented with a single species each.  Family Anatidae was the most dominant representing 13.89% (n=10) of the total species recorded.  Among the reported species 75% (n=54) were resident while 25% (n=18) were migrant.  Common Pochard Aythya ferina assessed globally as Vulnerable, while Painted Stork Mycteria leucocephala, Oriental Darter Anhinga melanogaster and Black-headed Ibis Threskiornis melanocephalus are assessed as Near Threatened, whereas the rest of the species were in the Least Concern category of the IUCN Red List 2019.  The omnivorous feeding habit was shown by the maximum number of species while frugivorous and granivorous bird species were in the least numbers.  The rich avifaunal diversity of the Tilyar Lake confirms it as a suitable habitat for both resident and migrant bird species. Therefore, the present study suggests the need for incorporation of appropriate protective measures for conservation of the avian heritage of Tilyar Lake, Rohtak.

A study on status and diversity of birds of Ramna Park, Dhaka, Bangladesh was conducted from July 2013 to March 2014. Data were collected through direct field observations where 6 days had been spent in every month in the field. A total of 50 species of birds belonging to 11 orders and 28 families were observed. Of the 50 species, 84% were residents and 16% migrants, 50% were passerines, 50% non-passerines. Passeriformes presented the highest number (25 species) of observed birds. Only Clamator jacobinus was recorded as summer migrant among the migratory birds. We found Psittacula eupatria considered as Near Threatened globally according to IUCN. Corvus splendens was the most common with the highest number of individuals in comparison to other bird species. We observed single individual of Clamator jacobinus followed by Psittacula eupatria and Apus pacificus throughout the study. Regarding the relative abundance, 18% species were very common, 30% common, 16% fairly common and 36% few. Calculating the Shannon-Wiener and Simpson’s indices of diversity and species evenness, we found maximum number of species and individuals in the month of December while minimum in the month of July. Anthropogenic activities such as festivals, random assemblies and gatherings, dumping of plastics, polythene and papers, noise from the vehicles were common inside and around the park, which may be threats to birds.Bangladesh J.

Bagmati River is considered as a potential conservation area in terms of the bio-diversity conservation due to its unique and diversified habitat distribution. Due to various causes, the river is being polluted and hence habitat degradation rate is increasing. As a consequence, the direct effect is seen on birds inhabiting there. Aiming the assessment of bird's diversity, one year survey was conducted in Bagmati River from Tilganga Bridge to chobhar Gorge Bridge (here after termed as Bagmati river corridor) by applying the point count method .In the total enumeration, 100 of birds species were recorded among which 7 are listed in CITES appendix. The bird species that are regarded as globally threatened are not recorded in the study area. In this report, some potential patches in the study area, are described as hot spots, considering the higher probability of recording maximum number of birds species. The public voice is also collected to find out the public perception on the present status of birds of Bagmati river corridor using the questionaire method. Some causes of habitat destruction and some potential conservation measures are also mentioned.

Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller—typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated.
