Abstract Wetlands are an important habitat for all kinds of dependent water birds. They are vital habitats for resident as well as migratory birds for foraging, roosting and breeding activities. Kopra wetland is an important and suitable bird habitat for both resident and migratory birds in Chhattisgarh. This wetland fulfills the need of water for the surrounding agricultural land and it also acts as a site for food as well as a roosting ground to many resident and migratory bird species. Every year a huge number of birds including Waterfowl, waders and Terrestrial Birds migrate to this wetland between the months of October to March. A study was carried out to estimate the avifaunal diversity during three consecutive winter seasons from 2016 to 2018 and estimated 133 avifauna species belonging to 18 orders and 47 families. Out of 133 avifauna 80 resident and 53 migratory species were recorded, including four Near Threatened species which are Painted Stork (Mycteria leucocephala), Black-headed Ibis (Threskiornis melanocephalus), Eurasian Curlew (Numenius arquata), Blacktailed Godwit (Limosa limosa) and one Vulnerable (VU) Woolly-necked Stork (Ciconia episcopus) and one Endangered (EN) Egyptian Vulture (Neophron percnopterus).

Introduction Wetlands are extensively important for groundwater recharge, recreational activity, retention, and regulation of pollutants and it supports many aquatic floral and faunal species for sustaining their life (Crisman 2001). The waterdependent avifauna and their habitat are affected by various factors like food availability, hunting and poaching threats, the size of the wetland (Paracuellos 2006), and the abiotic changes in the wetlands (Jaksic 2004; Lagos et al. 2008; Vishwakarma et al. 2018). Not only the birds but all the organisms, belonging to the plant and the animal communities are affected by the physical characteristics of the environment (Wilson and Keddy 1986; Gaudet and Keddy 1995; Weiher et al. 1996; Euliss et al. 2004; Gillis et al. 2008; Rajashekara and Venkatesha 2017). In a wetland ecosystem, these biotic factors are mostly dependent on the seasons and hydrology (Hussain 1995). Praveen
