Özet

Determining the temporal change in avian population is crucially important in order to understand whether their population is increasing or decreasing. The information about population parameters will help in conservation and protection efforts of avian species in future. Hence, the present study was carried out to determine the temporal changes in avian species in the 2014/15 and 2018/19 periods in urban waterlogged area of Hyderabad district Sindh, Pakistan. The highest relative abundance (28229 bird individuals representing 50 species and 14 families) was detected in 2018/19 rather than in 2014/15 (17454 individuals representing 38 bird species and 12 families). Out of the 50 bird species detected in 2018/2019, 30 were migrants (18965 individuals); 15 residents (5370 individuals), and 5 resident-migrants (3897 individuals) and while in the case of 2014/15 period, 22 species were migrants (11547 individuals), 15 residents (5247 individuals) and one resident-migrant (660 individuals). IUCN and BirdLife Status indicated that one migrant species was critically endangered; two species Rare/Accidental/Vulnerable and the rest of the 23 species were of the least concern. All resident bird species were totally protected (LC) while one resident-migrant species was data deficient. Foraging guild structure indicated that omnivore (32.489%) and Piscivore (12.808%) were the most dominant guilds of 2018/19 rather than 2014/15 while Carnivore was absent in detections of 2014/15. Alpha diversity analysis indicated that urban seasonal waterlogged was more diverse, rich and evenly distributed in 2018/19 than 2014/15. The findings of this study indicated that urban seasonal waterlogged area is suitable habitat (foraging sites and stopover) for a wide array of waterbird species especially migrant birds to refuel, rest, and forage.
