Wetlands are very fragile and constitute treasure of biodiversity. The avifaunal diversity in Ousteri freshwater wetland, Puducherry, India, was studied to form a baseline data about several local and migratory bird species of this wetland. Birds are surveyed by direct sighting, calls and variable width line-transect method was carried out in December, 2009 to January, 2010. It resulted in total of 109 species of both migratory and local birds. Such unique diverse systems are under threats like reduction in water retention in this pond in summer, weed infestation; variations in food availability in different seasons, hunting, poaching and threat of predation on the breeding activity of birds affected the avifauna diversity in the study area.DOI: 10.3126/on.v8i1.4335

The main thrust in this research work has been given on the evaluation of current status of Avifauna associated with Shallabug wetland. The main objectives were to evaluate the bird population fluctuation, to determine various threats to waterbirds and their habitats, and to present the remedial measures based on the key issues identified. For the purpose of present investigation, the study area was divided systematically into three study units of 700 m² each. Visual census method was used for the estimation of bird population. Visual counting was made with the help of high power field binocular (SG- 9.2) from respective vantage points. The birds were observed on the monthly basis in 2008 and the fluctuation in bird population was determined in different seasons: summer, autumn and winter.  The observations were made from 5:00 am to 7:00 am (when they come out from their resting place) and 6:00 pm to 7:00 pm (when they approach towards their resting place). The analysis of the results showed that the Shallabug Wetland is particularly important for migratory bird species and marsh land breeding species. The wetland was also found important for long distance migrants as a stopper site for feeding and resting. The bird population showed fluctuation with site differences as well as with changing seasons.

One of the animals that are easy to find is a bird. Based on data about the increase in the number of bird species, it can be ascertained that these animals can be found in every region in Indonesia, with diverse species and even species that are endemic to a certain area. West Papua is one of the regions in Indonesia which is rich in various species of birds, including Cendrawasih which can also be found in the Natural Forest of Malagufuk Village, Klayili District, Sorong Regency. Based on information from the surrounding community, several types of Cendrawasih are often seen in the natural forests of Malagufuk Village, but their diversity and population are not known with certainty. This study aims to determine the diversity of species and population of Cendrawasih birds in the natural forest of Malagufuk Village, Klayili District, Sorong Regency, West Papua. Thus, the results of this study are expected to be a source of data in the context of preserving and protecting the existing Cendrawasih species. Data collection on the species composition and population of Cendrawasih was carried out using the Line Transect method by making 10 observation lines with a line length of 500 m each and a distance between lines of 100 m. The results showed that there were found 3 spesies of Cendrawasih with estimated populations and densities as follows: Cendrawasih Kuning Kecil (Paradisaea minor) had an estimated population of 7.48 individuals with a density of 2.93 individuals / ha; Cendrawasih Raja (Cicinnurus regius) has an estimated population of 5 individuals with a density of 1.67 individuals / ha; and Toowa Cemerlang (Ptiloris magnificus) had an estimated population of 2.22 individuals with a density of 0.74 individuals / ha. When the research was carried out, it was seen that the three types of Cendrawasih used several types of trees as places for activities (playing or dancing), namely Matoa (Pometia coreacea), Merbau (Intsia bijuga), Damar (Agathis dammara). Beringin (Ficus benjamina), and Pala hutan (Myristica sp) with tree heights above 20 m.

This study was carried out to assess the status and conservation issues of migratory water birds in Komaranahalli Kere, a lake in Malebennur, Harihar Taluk, Davanagere District from November 2012 to October 2013. The dominant family was Ardeidae represented by 10 species, followed by the Scolopacidae with seven species.  The families with lowest representations of one species were Podicipididae, Anhingidae, Rostratulidae and Recurvirostridae. The study revealed that the lake harbors many resident and a few migratory bird species. Among the species recorded five species namely the Black-headed Ibis Threskiornis melanocephalus, Oriental Darter Anhinga melanogaster, Black-tailed Godwit Limosa limosa, Painted Stork Mycteria leucocephala and River Tern Sterna aurantia are Near Threatened. The present study location is also facing tremendous conservation challenges by the impact of anthropogenic alteration of the habitats in and around the lake. Though the lake is highly disturbed, it still provides some potential habitats for a few migratory and several resident water bird species.

A survey of the avifauna of district Kargil was carried out using a combination of Line Transect method and Point Transect method to record the avifaunal diversity and their feeding guilds. The bird census was carried out from April 2010 to April 2012. The study area lies between 340 15' to 340 47' 30'' North latitudes and 75? 45' to 76? 3' East longitudes. The area constitutes a part of the Trans-Himalayas in Jammu And Kashmir State. The area is comprised of high rocky mountains with snow bound peaks and arid desert devoid of natural vegetation. The altitudinal range of the area varies between 2430m to 4192m above msl. The study revealed 102 species of birds. Six major feeding categories were considered viz. insectivorous, carnivorous, grainivorous, omnivorous, frugivorous and herbivorous. The highest number of bird species was observed to utilize more than one feeding guild followed by insectivorous, carnivorous, grainivorous and omnivorous bird species. Feeding guild of 1 species i.e., Black-crowned Night Hereon was not recorded during the study.

We assessed species diversity and relative abundance during February - March by employing transect method in four line transects and 30 point count stations, and associated threats by direct observations and consultation with people (n= 1) living in vicinity of Phewa wetland. We counted 2651 bird individuals of 148 species belonging to 104 Genera of 44 Families under 11 Orders. Anatidae and Passeriformes with 11% and 39%, respectively were the dominant family and order among the recorded species. Out of these, seven bird species were globally threatened and 12 were nationally threatened. Terrestrial birds had higher species diversity (H'= 3.27), species richness (R= 11.98) and species evenness (e= 0.74) as compared to wetland birds (H' = 3.07, R= 8.44 and e = 0.73). Common pigeon (7.50%) was the most abundant bird followed by lesser whistling duck (6.98%). People in the vicinity of Phewa wetland reported that water pollution caused by domestic sewages and waste water disposal was the major threat to birds and their habitat. Phewa wetland is providing crucial habitat to adequate residential and migratory bird species for which it should be protected for further enhancement of number of avian species.

The grasslands of Nepal's Terai are extremely rich in bird species with several globally threatened species. These birds are often quite sensitive to changes in the habitat quality and microclimate around them making them ideal indicators of the grassland ecosystem health. Unfortunately, very little is known about the grassland avifauna. This study was conducted to determine the avifaunal composition and diversity with respect to the vegetation height and patch openness in the grasslands of Shuklaphanta Wildlife Reserve by using open width line transect method along fire-lines. The birds and the vegetation were recorded using BBIRD protocol and the species diversity was calculated. The Kruskal-Walli test for differences in median populations and Canonical Correspondence Analysis (CCA) were also conducted. This study recorded 104 species birds belonging to 39 families among which 29 species were insectivorous, 17 herbivorous, 17 carnivorous and the rest omnivorous with 94 resident species and 10 summer visitor species. Covered patches of short grassland had highest number of species while covered patches of tall grasslands had the highest species diversity. The results from KruskallWallis test and CCA highlighted the need for the maintenance of ecological integrity of all the grassland habitat areas.
