“…In another cluster, the piscivorous and the molluscivorous birds have less Euclidean distance from the wetland habitat. It is known that the abundance of fishes and molluscs is high in wetland habitats, which attracts the wetland birds that are mainly dependent on these organisms for their food (Prajapati and Prajapati 2013;Panda et al 2021). The frugivorous and the granivorous guilds are in one cluster, which is suggestive of the fact that the fruit-eating birds are mostly grain-eating species that share nearly the same habitat, in the ecosystem like forest and farmlands nearby (Mulwa et al 2012).…”

Background Habitat heterogeneity clearly distinguished in terms of availability of food and habitat resources and landscape features (natural or human-modified) play a crucial role in the avian species composition and population structure. To examine this, a study was carried out in Bhubaneswar, India, to understand the ecological niche distinction in birds based on habitat heterogeneity. Regular sampling was conducted in 30 sampling sites covering six different habitat types in a predominantly urban landscape of Bhubaneswar for understanding the ecological niche in birds. The birds were classified into 11 types of foraging guilds. Results The insectivorous guild had the highest bird species richness (181 species) and the omnivorous guild had the lowest (11 species). The piscivorous guild and wetland habitat had the strongest linkage, followed by the insectivorous guild and agricultural land. The frugivorous guild was significantly correlated with forest habitats (r = 0.386, p < 0.01) and park and garden habitats (r = 0.281, p < 0.01). This urban area hosted a higher number of bird species in certain habitat types, viz., agricultural lands (52%, 115 species) and forest patches (50%, 111 species). Conclusion The present study highlights the importance of agricultural lands, forest patches, parks and gardens, and wetlands inside the cityscape for supporting avifauna. It is therefore suggested that such habitats should be conserved inside an urban area to protect native avifauna. Thus, the city development plan must invariably include strategies for conserving the forest patches inside the urban area. Measures must be taken to restrain the degradation of agricultural lands and reduce their utilization for non-agricultural purposes, which will help in further reducing the bird population decline in the urban landscape.

“…This phenomenon is potentially attributed to the presence of ample food resources and shelter that accommodate a wide array of bird species. Habitats like woodlands and farmlands create an environment conducive to diverse insect and food resources, thereby attracting birds with insectivorous and omnivorous diets to actively forage in these habitats (Ehlers Smith et al., 2015; Panda et al., 2021).…”

“…This interaction has long been regarded as an excellent ecological approach for studying different biodiversity clans due to the ecological generalisation behaviour of birds (Gavish et al, 2021). In avian ecology, a feeding guild is formed when a community of birds utilise the same group of resources from the environment (Panda et al, 2021). Potential guilds can be identified by grouping the species based on their shared behaviour such as foraging, nesting and habitat utilisation (Verner, 1984).…”

Habitat heterogeneity plays a vital ecological role in influencing community ecology dynamics. We evaluated the relationship between habitat heterogeneity and land‐use cover with avian community structure in the human‐dominated landscape of the Katavi‐Rukwa ecosystem in Tanzania. We used the fixed‐radius point count method to record birds in different habitats. We calculated the relative abundances and the Shannon‐Wiener diversity index of bird guilds across habitats as well as the Normalised Difference Vegetation Index (NDVI) and estimated land‐use cover of the study area from Landsat 8 images. We grouped birds into five major guilds: Insectivore, Granivore, Omnivore, Carnivore and Nectarivore. Among the guilds, Insectivores, Omnivores, Nectarivores and Carnivores were positively correlated with an increase in NDVI, while Granivores were negatively correlated with an increase in NDVI. Among the habitats, woodland had high species diversity whereas riverine had low species diversity. Our findings highlight the importance of habitat heterogeneity in biodiversity conservation in human‐dominated landscapes, and we suggest implementing conservation in these landscapes.

“…Wetlands are dynamic ecosystems that link aquatic and terrestrial habitats (Zedler & Kercher 2005;Bassi et al 2014;Panda et al 2021;Rajpar et al 2022;Yashmita-Ulman & Singh 2022). They have specific ecological characteristics, functions, and values.…”

Birds are considered sensitive indicators of ecosystem health and functionality in freshwater wetlands. Assessment of birdassemblages in wetland habitats is, therefore, emphasised from a sustainable management perspective. Bird surveys were conducted from October 2020 to September 2022. These surveys aimed to assess the community composition and status of avifauna in Dighal wetlands, an important bird area in the Jhajjar District of Haryana, India. Data collection employed point counts and opportunistic encounter methods. A total of 154 bird species belonging to 108 genera, 47 families, and 18 orders were recorded. Of these, 75 species were residents, 60 were winter migrants, and 10 were summer migrants. The greatest species richness was observed for the order Passeriformes (54), followed by Charadriiformes (22), Anseriformes (17), and the rest of the 15 orders. Anatidae was the most dominant family with 17 species, constituting 11% of the bird community in the study area. Data on local abundance revealed that 10 species were common, 23 were fairly common, 83 were uncommon, and 38 were rare in the study area. Among the recorded avifauna, one species is classified as Endangered, three as Vulnerable, and eight as Near Threatened in the IUCN Red List of Threatened Species; 17 species are listed in the Appendices of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES); and 11 are included in Schedule I of the Indian Wildlife (Protection) Act, 1972. These wetlands also support 40 species of birds, which have a declining population trend globally. The occurrence of migrants and species of global conservation priority underscores the importance of these wetlands as a conservation site and wintering ground for avifauna due to the extensive food resources and rich biodiversity they support. The present study provides baseline information for future research on monitoring bird assemblages and proper management of the Dighal wetlands of Haryana.
