The East Asian‒Australian Flyway (EAAF) is among the important flyways for bird migration, especially migratory shorebirds. Shorebirds fly from the northern to the southern hemisphere and back to their breeding ground, escaping from cold winter to hotter areas for their food, survival, and other ecological functions. Along their migration routes, they stop over at important areas, especially coastal areas that provide them with enough food and shelter. Coastal areas are facing rapid development and habitat destruction, which means ecological risks to migratory shorebirds such as loss or declination of feeding areas, less abundance of food, and diet contamination from heavy metals, pesticides, plastic, and other new emerging chemicals produced by industrial and agricultural activities. Human economic activities in the coastal areas including ecotourism may cause an ecological crisis for the sustainability of shorebirds’ population.
