Visitors to Dianchi Lake in Kunming city, capital of Southwest China’s Yunnan province, now have the chance to meet thousands of black-headed gulls, as the birds have migrated to the area during this winter.

Kunming is known as the "Spring City" for its mild climate and green environment all year around.
