The first batch of black-headed gulls gather at Haigeng Park in Kunming City, the capital of Southwest China’s Yunnan Province, Oct. 17, 2016. For more than 30 years, Kunming has provided an important habitat for the migratory birds from Siberia. The local government has introduced many measures to protect the gulls and also develop tourism. More black-headed gulls are expected to arrive in the city soon. (Photo: China News Service/Li Jinhong)
