The Survey of Avifauna in the natural habitat and their adjoining areas of Harbhajwala, Dehradun, India

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.

SummaryFrom mid-September 1993 to February 1994 avian species were inventoried at eight sites selected to sample the major biogeographic areas and threatened habitats of Masoala Peninsula of north-eastern Madagascar. The sites ranged from 10 to 1100 m elevation. Three forest types were inventoried: six sites included primary lowland rainforest (0–700 m), one site was characterized as moist montane forest (above 700 m), and one site was classified as littoral forest. Bird species and distribution were sampled using point counts and line transects, tree observations and opportunistic sightings; 85 avian species were detected. Line transects were the most productive technique for number of species detected. Twenty-four detected species were shared by all inventory sites. Six threatened and six near-threatened species were observed with notes on their ecology and behaviour. One endangered species, the Madagascar Serpent-eagle Eutriorchis astur, was first observed along a forest edge and then sighted several times at forest interior sites, suggesting that this secretive endangered raptor is not as rare as previously thought. Another species of indeterminate status, the Madagascar Red Owl Tyto soumagnei, was discovered by two villagers near one inventory site in modified habitat. Several rare and near-threatened species were found to be common throughout Masoala Peninsula: Scaly Ground-roller Brachypteracias squamiger, Short-legged Ground-roller B. leptosomus, Red-breasted Coua Cona serriana, Brown Mesite Mesitornis unicolor, Helmet Vanga Euryceros prcvostii, Bernier's Vanga Oriolia bernieri and Rand's Warbler Randia pseudozosterops; the last was only found along pristine riverine habitat. Three species were detected only at the high elevation montane forest: Grey-crowned Greenbul Phyllastrephus cinereiceps, Forest Rock-thrush Pseudocossyphus sharpei and Madagascar Brush-warbler Nesillas typica. Forest degradation from subsistence agriculture, shifting cultivation and fuelwood collecting threatens natural resources and biodiversity but conservation and development efforts can provide alternatives to meet the needs of the local people.Depuis la moitié du mois de septembre 1993 jusqu'au février 1994, nous avons inventorié la communauté avienne dans huit sites représentant la grande partie des habitats naturels de la Presqu'île de Masoala, Nord-Est de Madagascar. Ces sites ont des altitudes comprises entre 10 et 1100 m. Trois types de forêt ont été inventoriés: six sites de forêt primaire de basse altitude (0–700 m), un site considéré comme forêt humide de montagne (plus de 700 m), et le dernier classé comme for^t littorale. L'échantillonage était fait par point d'écoute et ligne de transect. Certains grands arbres ont été utilisés comme poste d'observation. Quatre-vingts cinq espèces d'oiseaux étaient détectées. Vingt quatre espèces sont communes aux sites inventoriés. Six espèces classées comme menacé et six autres en train de l'être sont observées avec des notes sur leur écologie et comportement. Une espèce en danger, l'Aigle serpentaire Eutriorchis astur, était observée pour la première fois le long d'une bordure forestière et puis vue plusieurs fois en pleine forèt. Ce qui suggère que cette espèce en danger et trèsdiscrète n'est pas très rare comme on a toujours pensé. Une autre espèce de statut indéterminé, l'Effraie de Soumagne Tyto soumagnei était découverte par deux villageois près d'un site d'inventaire dans un habitat dégradé. Quelques espèces rares et en train d'être menacées semblaient communes dans toute la Presqu'île de Masoala: Rollier terrestre écailleux Brachyptcracias squamiger, Rollier terrestre leptosome B. leptosomus, Coua de Serre Couci scrriana, Mésite unicolore Mesitornis unicolor, Eurycère de Prévost Euryceros prevostii, Oriolie de Bernier Oriolia bernieri et la Fauvette de Rand Randia pseudozosterops. Cette dernière se trouve seulement dans les habitats longeant les cours d'eau. Trois espèces sont seulement observées dans une forêt de haute altitude de montagne: Bulbul a tête grise Phyllastrepluis cinereiceps, Merle de roche de forêt Pseudocossyphus sharpei et la Fauvette de Madagascar Nesillas typica. La dégradation forestière causée par le besoin de surface cultivable, la culture itinérante et la collecte de bois de chauffe, menacent les ressources naturelles et la biodiversité du milieu. Seulement, la conservation en parallèle avec des efforts de développement peut fournir une alternative aux besoins de la population locale. Ceci est parmi les objectifs du Projet Masoala; cherchant des alternatives pour la population locale en même temps que la création d'un Pare National qui pourrait protéger une grande partie de bloc forestier de basse altitude de Madagascar, plus de 210.000 hectares.

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.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

SummaryAn annotated compendium of all those bird species known to have occurred in the lowland “Man and Biosphere” Beni Biological Station (B.B.S.) reserve is provided. Previous checklists are reviewed, together with sightings accumulated over the 1992–1995 period during which approximately 70 new species have been added to the reserve inventory, bringing the total to 478. Occurrence across the 12 delineated habitats, relative abundance and sighting documentation are given for each species. The avifauna of the B.B.S. is mixed biogeographically; in addition to a substantial component of lowland birds widespread throughout South America, it is composed of Amazonian, cerrado and chaco elements also. Representation from the Bolivian Yungas is minimal. Significantly, no less than four threatened and 15 near-threatened species have occurred, including the little known Bolivian endemic Unicoloured Thrush Turdus haplochrous, and the enigmatic White-winged Nightjar Caprimulgus candicans, known until recently only from Emas National Park (Brazil). Short accounts are provided detailing records of all of these species. Birds of the reserve core, consisting largely of humid tropical forest formations inundated during the austral summer, appear not to be subjected currently to any serious environmental degradation, although some subsistence clearance by Chimane Indians in the northern reaches of the reserve gives some cause for concern. Of much greater import, however, are changes occurring outside the confines of the B.B.S. These include increasing urbanization immediately to the west (and associated road upgrading) and forest fragmentation to the south brought about by logging. The latter is especially worrying because linkage of the B.B.S. forest block to surrounding forest is already physically tenuous, and therefore it is imperative that future logging activities be geared to minimize isolation occurring and the damaging restriction of gene flow. Monitoring in rainforest immediately south of the reserve should become routine to warn of putative avifaunal impoverishments. Extensive surveying of the 2,500-ha El Porvenir éstancia (savanna and related forest islands) due to be assimilated shortly into the B.B.S., which constitutes less than 2% of the area under consideration, has shown that it is used by no less than three threatened and up to nine near-threatened species. In the absence of data relating to other savanna areas (c. 15%) at present, the exact status of each species at the B.B.S. remains imprecise and begs for further research to be undertaken. Unfortunately, present management of the El Porvenir savanna is not conducive to the long-term maximization of populations of these species, several of which have local strongholds in this part of Beni. We recommend that the current policy of cattle ranching adopted by this éstancia should cease or be reduced dramatically, to minimize grazing and trampling damage, and that measures should be taken to reduce incursions of fires started wilfully in neighbouring properties. The Academia Nacional de Ciencias de Bolivia, which administers the reserve, should be encouraged to safeguard and enhance the savanna complement further by ensuring that the impending ratification of El Porvenir proceeds as quickly as possible, and by purchasing additional tracts of land to the south of the present southern reserve boundary, where feasible. Such actions should not only secure the future of the biota of the savanna habitat within the B.B.S. but also should ameliorate the degree of isolation which has occurred already by preserving the “curiches” (former river beds) and forest islands which act as access corridors for forest-dwelling and other birds.

The present study was conducted in Sultanpur National Park Gurgaon, Haryana (India) from February, 2011 to January, 2012 to analyze the avian diversity along with its status and abundance. During the study period, a total of 113 species of birds belonging to 14 orders, 35 families and 80 genera were identified. Maximum 41 species belonging to 12 families of order Passeriformes represented 36.28% of the total identified avian fauna while Podicipediformes and Strigiformes were the least represented avian orders (0.88%) with one species each,namely, Little Grebe, Tachybaptus ruficollis and Spotted Owlet, Athene brama respectively. Out of total reported 113 species, 64 were ‘resident’ species and 49 were ‘migrant’ species. Most of the migratory species were winter visitors except Red throated flycatcher, Ficedula parva; Orange Headed Thrush, Zoothera citrine and Eurasian Golden Oriole, Oriolus oriolus which were summer visitors. In all, 42 species were ‘common’, 33 species were ‘uncommon’ and 38 species were ‘occasional’ bird species. Based on sighting, White Breasted Kingfisher, Halcyonsmyrnensis; White Breasted Water Hen, Amaurornis phoenicurus; Common Moorhen, Gallinule chloropus; Black Wing Stilt, Himantopus himantopus; Red Wattled lapwing, Vanellus indicus; Cattle Egret, Bubulcus ibis and Indian Pond Heron, Ardeola grayii were common wetland bird species of Sultanpur National Park while Pied king fisher, Ceryle rudis and Coppersmith Barbet, Megalaima haemacephala were ‘rarely sighted’ bird species. During the study period, 7 ‘globally threatened’ species, namely, Painted Stork, Mycteria leucocephala; Black neck Stork, Ephippiorhynchus asiaticus; Black headed Ibis, Threskiornis melanocephalus; Darter, Anhinga melanogaster; Pacific Reef Egret, Egretta sacra; Sarus Crane, Grus antigone alongwith Hogson bushchat, Saxicola insignis were also recorded from the study area.

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 Vietnamese Mekong Delta has undergone much anthropogenic change in the last 100 years, and few areas of natural or semi-natural habitat remain. Despite the likely consequent loss of biodiversity, little documentation exists about the region's avifauna at any time in its history. Here, we present a review of the avifauna of the Vietnamese part of the Mekong delta based on various surveys and other fieldwork carried out since 1988, and an assessment of the few earlier data that were available. A total of 247 species has been recorded from the Vietnamese delta since 1988. Most pre-war data are now considered to be of uncertain validity. Some 50% of the species recorded since 1988 are dependent on wetlands. Of these, 20 are listed as globally threatened or Near Threatened. The delta supports, or is likely to support, internationally important numbers of 21 species of waterbird, including two threatened and three Near Threatened species. Annotations are provided for records of globally or regionally threatened species; for those species for which the Mekong Delta holds internationally important numbers; and those for which records described herein constitute range extensions. Information on the avifauna of the Mekong Delta presented here suggests it is of regional and global importance for the maintenance of wetland biodiversity.

SummarySerra da Capivara National Park covers an area of about 1,300 km2 in south-eastern Piauí, north-eastern Brazil. The park's vegetation is the endemic caatinga, with a few remnants of semi-deciduous forest in some canyons. The area has a reasonable diversity of plants, with 615 catalogued species. Since 1986, 208 bird species have been observed in the park and its buffer zone, including 10 threatened or near-threatened species, plus two recently extinct in the area. Other species are regionally rare and have declined over parts of their distribution. The park also harbours several threatened mammals and caatinga endemics. Despite having been created in 1979 the park remains effectively unprotected and unmanaged. Current levels of poaching and habitat destruction prejudice the future of several species, including some that have already vanished from other parts of the caatinga.O Parque Nacional da Serra da Capivara abrange uma área de aproxidamamente 1,300 km2 no sudeste do Piauí, nordeste do Brasil. A vegetação do parque é a caatinga, com alguns enclaves de mata semi-decíua. A área possui uma razoável diversidade de plantas, com um total de 615 espécies já catalogadas. Desde 1986, um total de 208 espécies de aves foram observadas no parque e sua zona-tampão, incluindo 10 consideradas ameaçadas ou quase-ameaçadas, além de duas recentemente extintas na área. Outras espécies são regionalmente raras ou tern declinado em parte de sua área de distribuição. O parque também abriga diversos mamíferos ameaçados, e endemismos da caatinga. Apesar de ter sido criado em 1979, o parque ainda não foi consolidado e é pouco mais que um parque de papel. Com os presentes niveis de caça clandestina e destruição de habitats, diversas espécies se extinguirão, incluindo algumas já desapareddas de outras partes da caatinga.

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.
