The photo taken on June 21, 2003 shows two gulls with black neb in the Shuangtai Bayou State Natural Reserve Area in Panjin, northeast China's Liaoning Province.
The gull with black neb, like other bird species in the world, is on the verge of extinction. By the concerted efforts of local government and a protective association, the bayou of Shuangtai River has become the largest breeding area in the world, with the number of gulls reaching about 5,000.
