Right now, migratory birds that have been wintering in the south are beginning their northward migration. Localities are steadily increasing investment in science and technology and improving ecological protection measures so that the birds' migration and breeding proceed more smoothly.

At the Poyang Lake wetland in Jiangxi, the migration of wintering birds has entered its peak period, with tens of thousands of swans, greylag geese, Siberian cranes and other migratory birds heading north every day. Using an AI bird-recognition system, staff can closely monitor data on bird numbers and population changes, helping researchers make effective scientific assessments. The Minjiang River Estuary wetland in Fujian is an important stopover on the East Asian-Australasian Flyway. Here is the Saunders's gull, a wild animal under first-class national protection. In recent days, staff have used an AI intelligent bird monitoring module to observe the Saunders's gull changing from white summer plumage to black breeding plumage, which is the most important preparatory step before their northward migration.

In the Yellow River Delta *** Nature Reserve in Dongying, Shandong, millions of migratory birds of various kinds migrate, winter and breed here each year. To provide the birds with a better habitat and breeding environment, the reserve has built 65 wetland waterbird habitat and breeding islands that can meet the needs of different birds for shoals, shallow water and deep water. At the Qilihai wetland in Tianjin, more than 200,000 migratory birds of various kinds have passed through this migration season. Staff have built artificial nests for the Oriental stork and set up a remote monitoring system to help them live and breed here.
