Budai is not only a wetland granary but also an environmental and ecological treasure, with many migratory bird habitats and bird-watching spots, among which Xincen Athletic Park in the South Budai Wetlands is the best viewing spot, where black-faced spoonbills and other birds can be seen at a distance of more than 200 meters. In addition, there are bird-watching walls, activity plazas, trails and parking spaces along the windbreak forest, providing a comfortable bird-watching environment for domestic and foreign scholars, experts and bird watchers.
