Well,these birds are the seagulls which migrate from harsh winters of Siberia and stay here on the banks of yamuna from november to march. I never knew why this place calls for attention until i went here. You get to see extremely beautiful view at the time of sunrise between 6-7am where people in the boats feed the birds and group of upto 500-1000 seagulls circle around the boats to create the magical scenic view which will forcefully let u to take out your camera and capture the moment. Its quiet difficult to get up so early in winter morning and reach here by 6'O click but trust me this place is worth it. This beautiful scenic view and spritual environment stuck in my heart.. i will never regret to spend my every single morning at this beautiful place "yamuna ghat".
