“…The Rock Pigeon was identified as the most commonly found species, constituting 6.935% of the observed bird population, owing to its behavioral adaptability to urban settings and resilience to anthropogenic disturbances (Polyavina et al 2022). The Black-headed Ibis was found to be the most uncommon species (0.012%), which might be due to their preferred habitat and foraging areas such as shallow seasonal or permanent wetlands, marshlands, and water-logged crop fields (Barik et al 2021). The decrease in marshy vegetation in the current study area due to the alteration of the landscape, which involves the construction of concrete buildings, and roads and also turning paddy fields into dry agricultural lands, affected the avian diversity.…”

The study investigates bird population dynamics in Bengaluru, India, post-lockdown, focusing on occurrence, seasonal abundance, species diversity, richness, dominance, and evenness. It covers 55 bird species across 52 genera, grouped into 32 families within 13 orders, with a notable peak in winter. Various indices, including Shannon Wiener, Margalef’s, Pielou’s, and Simpson’s, reveal significant seasonal differences in bird population characteristics. The Rock Pigeon Columba livia dominates, while the Black-headed Ibis Threskiornis melanocephalus is less prevalent. The study identifies Near Threatened species like Black-headed Ibis and Oriental Darter Anhinga melanogaster, along with Least Concern species per the IUCN Red List. Common species include Rock Pigeon, Large-billed Crow Corvus macrorhynchos, House Crow Corvus splendens, Black Drongo Dicrurus macrocercus, Brown Shrike Lanius cristatus, Common Myna Acridotheres tristis, Jungle Myna Acridotheres fuscus, Red-whiskered Bulbul Pycnonotus jocosus, and Streak-throated Swallow Petrochelidon fluvicola. The study aims to inform improved management and conservation strategies for Bengaluru’s diverse bird species.

“…Land covers are often considered as important habitat features for birds (Litteral & Shochat 2017). Google Earth satellite images are freely available with high resolution synoptic view of the study area and hence, used for the assessment of land cover features (Hu et al 2013, Barik et al 2021. We calculated the area of tree cover, bare land cover within the belt transect (i.e.…”

With rapid urban expansion and flourishing real estate sector, remaining green patches in many sub-urban/peri-urban areas are facing immense threat and/or being destroyed. We therefore, explored the avian abundance and richness of green spaces around temples (sacred sites) and compared them with adjoining green spaces without religious places (control sites). The species richness and abundance in sacred sites (12.16 ± 0.65 species; 25.54 ± 1.176 individuals) was significantly higher than control sites (6.31 ± 0.77 species; 20.04 ± 1.4 individuals). The compositions of avian communities of sacred sites were significantly different and the presence of temple positively influenced the species richness. GLMM also revealed that the species richness was positively influenced by the distance to building and tree cover area and not influenced by distance to road, areas of water body, bare land. Our findings indicate that the green spaces around the sacred places have greater avian diversity in semi-urban areas, and could be prioritized for the conservation of avian diversity. Generating local support could be relatively easier due to traditional, religious and/or cultural belief against tree felling around the places of worship.

Influence of land cover features on avian community and potential conservation priority areas for biodiversity at a Ramsar site in India

Background Wetlands provide diverse ecological services to sustain rich biodiversity, but they are recklessly exploited around the globe. East Kolkata Wetlands (EKW; Ramsar site No. 1208, ~ 125 km2) was once very rich in faunal diversity that declined over the years due to various anthropogenic pressures. In such scenarios, effective management plans need to contemplate local and landscape level initiatives and prioritize areas for conservation. Studying the foraging guild structure and spatial patterns of relationship between bird and its environment provides important insight of ecological processes of avifauna. Thus, we carried out extensive surveys in 142 point count stations to explore the diversity and foraging guild structure of birds in EKW. We addressed two important questions that how bird diversity varied from the outer periphery of the city towards the wetlands and how bird diversity is influenced by land cover features at local and landscape level in wetland complex. The goal of this study was to prepare a spatial map of avian diversity and to find the conservation priority areas for birds in this internationally recognized wetland complex. Results We recorded 94 species of birds and the Shannon diversity index values ranged between 1.249 and 3.189. We found that the avian diversity increased with increasing distance from city periphery. Omnivores and insectivores were the dominant foraging guilds, followed by carnivores, granivores, frugivores and piscivores. Generalized Linear Models revealed that bird communities were positively influenced by areas of wetlands, dikes and banks, agricultural field and emergent vegetation, and negatively influenced by built-up area. In the projected spatial map of species diversity, 74.15 km2 area has high diversity. Finally, we identified 12.82 km2 of top 10% conservation priority areas. Conclusions Low bird diversity near city periphery is related to habitat degradation due to anthropogenic pressure. Dominance of omnivores and insectivores indicates a possible impact of urbanization in EKW. We suggest that a mix of agricultural field, wetland areas and emergent vegetation helps to sustain a greater avian community. Besides, protection of conservation priority areas, restoration of the degraded habitats and reduction of threats (particularly in the north-eastern parts of EKW near the city periphery) will ensure the conservation of avifauna, and also the overall biodiversity of EKW.
