Hundreds of red-billed gulls spend winter in southwest China city
Some 400 red-billed gulls have made southwest China's Chongqing Municipality their home during the winter time. Many people came to take photos with these birds. Chongqing was not a popular destination for red-billed gulls in past. After years' of efforts in dealing with pollution and in restoring ecology, the local environment began to attract wild birds to come and spend their winter there.
