These are the Siberian gulls they came at triveni sangam in the Winter season. I take this photos in winter season in Dec 2019 when my trip is started this was the first point of my trip.
The gulls travel thousands of miles to India during the Siberian winter in October and return home in March.
These birds are human-friendly and can be seen sitting on boats also occupied by the pilgrims and tourists.
Above photo shows that bird on the top of boat.The whiteness of the birds dazzles on the waters of Ganga and Yamuna. These Siberian birds present a mesmerizing view at the Sangam throughout the winter season
