Black-headed gulls began spending their winters in Kunming, Southwest China's Yunnan province, 30 years ago. Gulls have become the special scenery of Kunming's winter. [Photo/Xinhua]

Two young people feed the black-headed gull in Kunming's Cuihu Garden on Dec 3. Large groups of black-headed gulls began flying to Kunming in winter 30 years ago. Some believe that these black-headed gulls are from Siberia. But there's no evidence to show where these black-headed gulls are from and where will they go after they leave Kunming. On Dec 2, a large welfare activity themed "Where Are the Gulls Going" was launched. Gulls were installed with GPS trackers to see their exact flight path. [Photo/Xinhua]
