Method of the study
To study the avifaunal diversity we chose the Line Transect Method. This generally follows a way of bird watching in a linear fashion quite in the form of straight path extending from one point to another.
We were divided into 2 groups; one group observed the birds in the coastal area and the other group observed the birds along the estuarine area. Complete silence was a must criterion in order to observe the activity of birds.
