A total of 6.29 square km of Dianchi Lake's surrounding wetlands have been built, providing an excellent habitat for black-headed gulls and other bird species, she said. "The presence of black-headed gulls brings vitality to Kunming. With them around, even winters feel warm," Wang said. "...
A biologist studied the migration patterns of a particular bird species. They used GPS trackers to follow the birds' movements over a two - year period. The study revealed that the birds migrated towards the south in winter, covering a distance of approximately 3000 kilometers. In spring, they...
