The identification and construction of ecological corridors for birds are important means to maintain the integrity of ecosystem and promote the migration of species.A scientific and feasible framework for identifying and optimizing ecological corridors for birds was constructed in Fengxian New City， a rapidly urbanizing area in Shanghai.4 common bird species including eurasian tree sparrow （Passer montanus）， common blackbird （Turdus merula）， common moorhen （Gallinula chloropus）， and eastern cattle egret （Bubulcus coromandus） were selected as focal species to simulate the pattern of regional ecological corridors with InVEST model and MCR model and establish an evaluation index system based on the data of field survey for verification.The results showed that the total area of patches （i.e.the area of ecological source） meeting the standards of high-quality habitat for the 4 bird species was 18.2 km2， 19.3 km2， 10.4 km2， and 13.5 km2， respectively， mainly distributed in woodlands， shrub grasslands， farmlands， and ponds.66 ecological corridors were identified， with fewer corridors in the core area of Fengxian New City， with a high risk of fragmentation and weak connectivity， while a relatively complete network of corridor was formed in the peripheral water bodies， farmlands， and densely forested areas.The deviation of control-points after optimization for the 4 bird species decreased by 0.25， 0.15， 0.16， and 0.27， respectively， and the ecological connectivity was significantly improved.It will provide a scientific basis for the construction and ecological restoration of corridors for birds in Fengxian New City， and offer a technical reference for the planning of the ecological corridors in similar rapidly urbanizing regions， which helps to promote the integration of urban–rural green and high-quality development of ecological spaces in cities.
