Abstract | The lake manchar is considered as one of the largest freshwater lakes in Pakistan, it’s located in district of Jamshoro. This wetland plays a substantial role in providing habitats to variety of resident and migratory birds. It provides shelter to the vast biodiversity that has daily and seasonal dependencies for all the life-support systems. Birds use this lake for drinking water, breeding, rearing young ones and social interactions. Meanwhile, birds play important role in balancing the ecosystem and food web of the ecosystem by conserving maintainable population levels of prey and predator species, and after death provide food to scavengers as well as decomposers. Birds are best pollinators, help in plant production through their services as pollinators or seed dispersers and increase forest growth, also help in environmental conservation. Considering the valuable role of wetlands and importance of avifaunal species in agriculture, food chains, ecosystem and pharmaceutics, a comprehensive study is carried out to evaluate diversity of socio-economically valuable avifaunal species at Manchar Lake. Monthly field surveys were conducted from January 2024 to October 2024, resulting in the collection of 80 specimens of Nycticorax nycticorax. Minor variation was recorded in body parameters including body weight, size of beak, body length, wingspan, limbs length, length of tail feathers, and width of web. Nycticorax nycticorax Weight of body 302±1.53 Length of beak 72± 1.20 Length of Wingspan 190±3.22 Length of limbs 787±140.5 Length of tail feathers 314±3.12 limbs Length of body 21.5±0.95. Nycticorax nycticorax was recorded to be the predatory bird, and their occurrence was abundant in the lake premises. The highest prevalence of recorded species occurred in January, February, and March, with the lowest richness observed in June and July. The study concluded that Manchar Lake is experiencing significant pollution due to runoff from agricultural fields, residential areas, and other sources. This pollution, combined with factors such as massive hunting, climatic changes, seasonal fluctuations, and decreasing food resources, has led to a decline in bird populations at the lake |
