“…The species-level identification of the observed birds was done using available books, literature, and other sources of online identification and also with the help of experienced bird watchers. Distribution, status in Assam, habitat guild, and feeding guild were included in a final checklist of the observed birds (Ali, 1949;Manakadan and Pittie, 2001;Grimmett et al, 2014;Chakdar et al, 2016;Hussian et al, 2018Hussian et al, , 2022.

Rice (Oryza sativa L.) is one of the most effective crops for absorbing carbon dioxide. Paddy is a temporary reservoir for rainwater during the rainy season, prevents soil erosion, and emits oxygen through photosynthesis. In Assam, it occupies 88.89 percent of the net cropped area. Paddy field ecosystems are also home to various cultivated and wild species of plants and animals where numerous aquatic and bird species can be found. These fields provide waste rice, a crucial food source for various bird species. The quantity of waste rice positively correlates with rice yields, and birds often feed on freshly planted rice seeds. Paddy fields constitute a semi-aquatic ecosystem that is heavily infested by insect pests. These fields also attract waterfowls, wading birds, shorebirds, and other waterbirds for migratory movements and foraging. From this pilot study conducted in the paddy field ecosystem surrounding the Assam University campus in Silchar we report 95 species of birds that belong to 37 families and 14 orders. Highly sighted avifauna included Egret, Heron, Bittern (family Ardeidae), Waterhen (family Rallidae), Kingfisher (family Alcedinidae), Drongo (family Dicruridae), and Dove (family Columbidae). Interestingly, eight 'Least Concern' bird species according to the International Union for Conservation of Nature (IUCN) – Hooded Pitta (Pitta sordida – family Pittidae), Cinnamon Bittern (Ixobrychus cinnamomeus – family Ardeidae), Watercock (Gallicrex cinerea – family Rallidae), Common Sandpiper (Actitis hypoleucos – family Scolopacidae), Emerald Dove (Chalcophaps indica – family Columbidae), White-Browed Piculet (Sasia ochracea – family Picidae), Dark-Necked Tailorbird (Orthotomus atrogularis – family Muscicapidae) and Brown Fish-Owl (Ketupa zeylonensis – family Strigidae) as well as a ‘Vulnerable’ species Lesser Adjutant Stork (Leptoptilos javanicus – family Ciconiidae) and ‘Near Threatened’ species Alexandrine Parakeet (Psittacula eupatria – family Psittacidae) were also noted. Out of a total 95 avian species, 46 species belonged to the insectivorous category, accounting for the greatest number according to the feeding guild recorded within different line transects in Visual Encounter Surveys (VES) conducted weekly from March 2023 to August 2023. Although the avifaunal studies have enormous potential in the Barak Valley, conservation measures are essential to protect the biodiversity. Public involvement in awareness campaigns and conservation activities is crucial for conserving avian diversity within the Valley. As paddy fields are used primarily by grassland and wetland bird species, there are significant information gaps in the monitoring of bird populations in paddy cultivation as well as in different stages of rice growing cycles, which makes it essential to understand the importance of paddy fields on avian populations as well as diversity.

“…The study sites are grazed by domestic animals such as cattle, buffaloes, sheep, and goats, including indigenous cattle such as Punganur, Ongole, Deoni, and Hallikar (NDDB, 2018). These mesic savannas provide habitat to many native birds such as francolins, harriers, partridges, quails, and larks (Manakadan, 2014; Madhusudan et al, 2021) as well as native mammals, including as four‐horned antelope ( Tetracerus quadricornis ), black‐naped hare ( Lepus nigricollis nigricollis ), little Indian field mouse ( Mus booduga ), Indian gerbil ( Tatera indica ), blackbuck ( Antilope cervicapra ), chital ( Axis axis ), and sambar ( Rusa unicolor ) (FES, 2003). To conduct this research, we engaged directly with village institutions that promote the rights of their members through participation in management decisions and equitable benefit sharing (Kegamba et al, 2022).…”

Human activities in mesic savanna ecosystems have resulted in plant communities that are heavily dominated by fire‐tolerant grass species, are less diverse, and offer fewer ecosystem services such as palatable plant biomass. Experimental studies manipulating fire and grass presence have mostly been conducted in ecosystems invaded by exotic grass species. However, these experiments are also relevant to ecosystems that have become dominated by native grass species due to changes in human activities. Our study compared three different management treatments in the Eastern Ghats of India, where mesic savanna ecosystems are highly dominated by the unpalatable native Cymbopogon grasses, specifically: (1) control (both Cymbopogon grasses and fire are present), (2) fire exclusion, and (3) manual removal of Cymbopogon grasses and fire exclusion. We found that both grass removal and fire exclusion were necessary to significantly increase palatable herbaceous plant biomass and species diversity, and that species diversity responses were only significant at larger spatial grains of investigation. High site‐to‐site variation in the grass removal and fire exclusion treatment prevented us from detecting significant differences in species composition across treatments, even though particular palatable grass species benefited from the treatment. Our study is in line with research from other mesic savanna systems showing that fire management alone is not sufficient to transition ecosystems to a desired or historical state. We demonstrate how normally costly management practices, such as manual removal of dominant grasses, can be reasonably achieved through collaboration between scientists, community governed village institutions, and government and nongovernment agencies in socioecological systems.

“…Vulpes bengalensis is opportunistic feeder (Johnsingh, 1978). The foxes are nocturnal in habit and eating regimen includes arthropods, small mammals, birds, reptiles, and different vegetative parts (Johnsingh, 1978;Johnsingh and Jhala, 2004;Manakadan and Rahmani, 2000;Cavallini and Lovari, 1991;Vanak, 2003). The presence of many types of vertebrates and invertebrates prey species were isolated by the fecal examination in southern Tamil Nadu (Johnsingh, 1978).…”

The study on food compositions of the Indian fox (Vulpes bengalensis) was carried out in Balotra (Barmer) in hot desertic land. This threatened species listed with Schedule II of Wildlife (Protection) Act 1992. This opportunistic and omnivorous animal feeds upon small rodents, birds, eggs, snake, lizards and insects. It also feeds upon seed and seasonal fruits of Capparis decidua, Acacia tortilis, Acacia senegal, Aerva javanica, Prosopis cineraria, Prosopis juliflora, Salvadora persica, Ziziphus species, Cucumis melo, Citrullus lanatus, Cordia myxa, Punica granatum. Direct observation technique and scat analysis were used to recognize the diet compositions. In total, 202 scats were collected across the study sites during the year of 2015 to 2018. Scats are analyzed to categorize the prey species of the fox. Seasonal variations were found in fox’s diet. During winter season the fox mostly depended upon ber, aves and mammals while in summer it mostly likes Prosopis juliflora, Acacia tortilis, Prosopis cineraria, hair and bones of animals. During monsoon season it feeds on Ziziphus and small mammals.
