Population Pattern

Assessments of avian communities’ composition in different habitats give an emphasis in monitoring environmental perspective. Depending on specific habitat functioning, their population pattern helps to determine the ecological health of an area. Bird surveys were accomplished on a fortnightly basis from October 2019 to September 2020 using Scan sampling, Point count and Line transect methods for evaluation of species abundance and richness in and around Ottu Reservoir, district Sirsa, Haryana (India). A total of 114 species comprising 91 genera, 47 families and 18 orders were recorded, among which 76 species were resident, 30 winter migrants and 8 summer migrants. Out of reported 114 species of birds, one species was vulnerable, 6 Near-threatened as listed by IUCN. Three bird species were listed under Schedule-I and the remaining species under Schedule-IV of IWPA (1972); six species under appendices of CITES (2012). Species such as Rock dove Columba livia, Lesser Whistling-duck Dendrocygna javanica and Common Sandpiper Actitis hypoleucos with decreasing IUCN population trends were reported abundantly in the study area. Analysis of feeding guilds results revealed that Carnivores as predominated guild due to enriched food material. The presence of diverse plantation, aquatic body, serenity and agricultural fields serve the reservoir as potential habitat for residential and migratory species. Therefore, effective measures must be taken for the conservation of this area as a potential site for avian diversity.

The line transect method has been employed to assess species diversity, population densities and community structure of birds breeding in a mosaic of Kalahari Woodland and farmland, NE Namibia. The transect, 4.5 km long, was surveyed in 2014 and 2015. The total annual rainfall in 2014 was much higher than in 2015 (427 mm vs. 262 mm). In total, 40 breeding species in 2014, and 46 in 2015 were recorded. Six species were dominant in 2014 (Cape Turtle Dove, Laughing Dove, Emerald-spotted Dove, Blue Waxbill, and White-browed Scrub Robin) and only three species in 2015 (Cape Turtle Dove and Blue Waxbill and Yellow-fronted Canary). Although the cumulative dominance in 2014 almost doubled that in 2015, the Community Index in both years was almost identical. Also diversity indices and evenness index were very similar in both years compared. Granivorous birds were the most numerous feeding guild. Their contribution was similar in 2014 and 2015 (46.7 % vs. 43.4 %). Two other feeding guilds, insectivores and frugivores, comprised together more than 50 % in both years. The number of bird species and species diversity were not influenced by the differential rainfall. However, contrary to expectations, population densities of most bird species (at least the more numerous ones) were higher in the year with lower than in the year with higher rainfall. The number of species and species diversity was similar in the farmland and in neighbouring Kalahari Woodland in a pristine stage. However, population densities of most species were lower in the farmland than in the pristine woodland.

Field Edge

Most studies on edge effect are related to the forest-field edge, i.e. to the ecotone. However, there is a lack of studies attempting to investigate the effect of the distance from the forest/field edge on the avian communities in large continuous forests. The purpose of this study was to investigate this issue. The study area comprised a continuous coniferous forest, the so called Niemodlin Forest, situated in Opole Silesia, SW Poland. The line transect method has been employed in this study. In total, 54 breeding bird species were recorded. On particular 0.5 km section, the numbers varied from 34 to 48. Both the number of species and number of breeding pairs only slightly decreased with the distance from the forest/field edge. Overall, the differences between the mean densities of breeding species on 10 sections were not statistically significant. The Chaffinch Fringilla coelebs was by far the most numerous bird species, recorded as eudominant in 164 out of 165 sections. The Chiffchaff Phylloscopus collybita, Willow Warbler Phyloscopus trochilus and Blackap Sylvia atricapilla were dominants in all 10 sections, while the Blackbird Turdus merula dominated in nine (90%) and the Robin Erithacus rubecula in eight (80%) sections. The communal dominance slightly increased, but the number of dominant species and Pielou’s Evenness Index remained stable with the increase of the distance from the forest/field edge. While Shannon’s Diversity Index remained constant, Simpson’s Diversity Index decreased markedly with the increase in distance from the forest/field edge. The proportion of long-distance migrants slightly decreased, while that of short-distance migrants and residents remained constant with the increase in the distance from the forest/field edge. Strikingly, no such changes in the proportion of all feeding guilds were shown. More than half of all breeding bird species show a negative correlation between population density and the distance from the forest/field edge. The dominance of some species decreased with the increase of the distance from the forest/field edge: Hawfinch Coccothraustes coccothraustes, Starling Sturnus vulgaris, Blue Tit Parusa caeruleus, Raven Corvus corax, Wren Troglodytes troglodytes, Wood Pigeon Columba palumbus, and Wood Lark Lullula arborea. With the exception of the Yellowhammer Emberiza citrinella, the clearcuts in this study, not only failed to increase, but most probably caused a decrease in the number of both species and individuals. It is because clearing not only creates edges, but also causes loss of forest habitat and often results in forest fragmentation. Edge and area effect may in fact interact, in such way that the edge effect may drive out the area effect, causing the increase.

Waterbird Species

Abstract Waterbirds constitute a prominent biota and reflect the ecosystem health and functionality of the freshwater wetlands. Documentation of the bird species assemblages of wetlands is therefore carried out as a part of monitoring of wetlands from a sustainability viewpoint. Using the emerging wetland of Purbasthali, West Bengal, India, as a model study area, the diversity of the associated bird species was estimated to supplement necessary information for conservation management of birds and ecosystems. The point count method was applied to count the waterbirds from each sighting location with a 25 m radius covering 360° arc and the counting period lasted 10 min for each site, and counts were made in the winter of 2016/2017. The data on the waterbirds encountered were recorded and subjected to diversity analysis, including the residential status, global population trend and feeding guilds. Apparently, the wetland was considered as suitable habitat for 27 waterbird species, which could be grouped under 24 genera, 10 families and 5 orders. Among these, the family Anatidae with maximum relative density and abundance dominated in the wetland. Out of the 27 recorded species, 5 species were widespread winter visitors, 3 species widespread resident, as well as, widespread winter visitors and 2 species were sparse local winter visitors. A globally near threatened species, the Black-headed Ibis (Threskiornis melanocephalus) was very common in the sampling sites. The waterbird assemblage in the wetland was dominated by carnivores followed by omnivores and herbivores. The abundance of the waterbirds with considerable variations in the foraging guild reflects availability and exploitation of multiple resources of the Purbasthali wetlands. Prominence in the differences in relative abundance of the different waterbirds could be linked with the heterogeneity in the habitat quality. The present information on waterbird assemblage calls for appropriate measures for conservation of the species and appropriate management of Purbasthali wetlands.

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.

<p>Bird communities are the composition of several bird species that live together in the same place, time and interact with other birds. The diversity of birds in an area can be used as an indicator of stabilizing an area. Changes of vegetation structures due to logging practices can affect the availability of resources for bird communities. The objective of the research was to examine diversity, richness, bird species abundance and bird community similarity at HS1 (logged forest 1974), HS2 (logged forest 1989/1990) and HS3 (fully logged forest 1989/1990) in Seblat Nature Recreation Park (SNRP). The research was conducted in July – September 2013. Data collection was conducted by point count method (total 36 points) and mist net method (total 4752 nets hours). The Research showed 85 bird’s species from 33 families were recorded. HS2 was highest value of diversity and richness (H ‘= 3.63, DMG = 10.07). The highest relative abundance species in HS1 was Emerald Dove (Chalcophaps indica), while HS2 and HS3 were Slender-billed Crow (Corvus enca). The bird community similarity was highest in HS2 and HS3 (ISj = 0.58).</p><p><strong>How to Cite</strong></p><p>Susanto, E., Mulyani, Y. A., &amp; Suryobroto, B. (2016).

Birds are important indicators to determine the quality of habitat. They played an important role in maintaining the balance of our ecosystem. This study aims to determine the species of birds and its diversity within the Central Mindanao University main campus. A line transect method combined with bird watching technique were used within the two month avian survey. A  total  of  27 species belonging to 21  families were  recorded namely, Accipitridae, Alcedinidae, Apodidae, Ardeidae, Artamidae, Bucesotidae, Campephagidae, Columbidae, Corvidae, Dicaeidae, Estrildidae, Hirundiniidae, Laniidae, Meropidae, Nectariniidae, Phasianidae, Pycnonotidae, Sturnidae and Sylviidae. Out of the 27 bird species observed, 18 resident, 3 resident-migrant, 5 Philippine endemic and 1 island endemic. The most observed species are Euarasian Tree Sparrow (Passer montanus) and followed by an introduced species which was Feral Pigeon (Columba livia). Most of the species observed were commonly found in urban communities, agroecosystem and along the forest edge. Some species of birds belonging to family Nictariniidae and Dicaeidae are associated in areas with flowering trees and there are seldom observed in other points. The average diversity of all points H’= 0.94 which is quiet low and it requires more sampling effort and other technique to record silent or shy species.

Abstract. Pandey N, Khanal L, Chapagain N, Singh KD, Bhattarai BP, Chalise MK. 2021. Bird community structure as a function of habitat heterogeneity: A case of Mardi Himal, Central Nepal. Biodiversitas 22: 262-271. Community structure of birds at different habitat types is underexplored in the montane environment of the central Himalaya. Therefore, this study explored bird community structure in different habitat types in Mardi Himal of the Annapurna Conservation Area, central Nepal, and tested association of different feeding guilds with the habitats. Data on the avian richness and abundance were collected in the winter and the summer of 2019 by point count method along the elevational gradient in every 100 m rise and analyzed using ordination methods. A total of 673 individuals of 112 bird species from 35 families under 13 orders were recorded. Among the observed orders and families, the order Passeriformes (77 species) and family Muscicapidae (16 species) were the most dominant. A linear species accumulation curve was obtained in both seasons. Species richness and abundance were found higher at forest edges of mid-elevations and insectivores were the most abundant birds. Frugivorous and carnivorous birds showed no specific association with habitat types, whereas, insectivores and omnivores were more abundant in pastureland and forest, respectively. Our results revealed that the community composition of birds varies with the habitat types and their feeding specialization is one of the major determinants.

Bird Habitat

Avifaunal diversity is the measure of species diversity via species richness and evenness. To this aim, avifaunal survey was conducted in the Institute of Forestry Complex, Hetauda from November 2017 to June 2018. Using line transect and point count methods, 132 species of birds were recorded, representing 15 orders and 44 families. Three species of these birds are in IUCN Red List while 90, 27 and 15 species are residential, visitor and migrant respectively. Higher Shannon diversity index (4.47) and Margalef index (18.78) indicate marked diversity and richness of bird species. A high value calculated for the Simpson index (0.98) represents higher evenness within the species individuals. Although, Pielou’s evenness index (0.92) shows uniformity in the species distribution, Shannon index seems to be influenced by diversity index, species richness and evenness values. The avifaunal diversity in the study area shows the importance of the Institute of Forestry Complex as a suitable bird habitat.
