Banggong Co Lake（Chinese name: 班公湖） extends from Rutog of Tibet, China to Indian controlled Kashmir. The bird islet where thousands of gulls inhabit is located in the lake. When spring comes, and warm air from the Bay of Bengal blows into the Ngari Plateau, groups of birds that have migrated from the cold plateau to the warm Southern Asian continent in the previous winter fly back to the islet. The best time to observe birds is from May to September.
Banggong Co Lake means "the long and narrow goose lake" in Tibetan language. It extends from Rutog of China to Indian controlled Kashmir. The eastern part of the lake belongs to China, while the western part belongs to Indian Kashmir.
The Bird Islet where thousands of gulls inhabit is located in the lake. The islet is small, about 300 meters in length and 200 meters in width, with red willows clustering along the lake bank. Gulls and their eggs can be seen everywhere in the islet: between rocks, in the grass, on the lake, and on the bank. There are also a small number of other birds and fowls, such as gray ducks that live on fish in the lake. When spring comes, and warm air from the Bay of Bengal blows into the Ngari Plateau, groups of birds that have migrated from the cold plateau to the warm Southern Asian Continent the previous winter fly back to the islet.
