Author(s): Harish Prajapati, Arun Kumar Roy Mahato
Abstract: Birds are the diverse group of fauna and a vital component of wetland ecosystem. The community structure and temporality of flock size are important life strategy of birds to survive in a particular habitat. Thol Lake is an important wetland system of varied species of birds, thus it was established as Thol Bird Sanctuary in the year 1988, which is located in the central part of Gujarat. The study was conducted to assess the annual pattern of flock size of aquatic bird species found in this sanctuary. The study was carried out on monthly basis to assess the flock size of aquatic birds and their temporal pattern in the sanctuary. A total of 9612 individuals of birds from 55 species and 730 flocks of 40 aquatic bird species were recorded during the study period. The highest frequency was recorded of Oriental Darter (9.74%), followed by Eurasian Spoonbill (8.99%) among the aquatic bird species of the lake. The mean flock size (39.25±11.56) of Common Coot was recorded as largest, followed by Common Crane (38.39±16.95) among all aquatic bird species recorded in this lake. The estimated population and flock size was recorded maximum during winter season and minimum during monsoon season.
