TIANJIN: More than 5,000 oriental white storks have been spotted in north China’s Tianjin Municipality since October, accounting for around half of the species’ total global population, local authorities said. As Tianjin’s ecological environment improves, greater numbers of migratory birds are flocking to the area, making use of its managed wetlands, with 100,000 birds of various species arriving since the start of autumn this year, according to Lu Hong, an official with the planning and natural resources bureau of Tianjin. To ensure that the migratory birds cross the city safely and survive the winter, the major wetland reserves, including Tianjin Beidagang and Qilihai, have taken timely measures, said Lu Hong. – Agencies
