This protected land is a refuge for shore birds and water birds. Some are resident species, while others are migratory. It is a key feeding and roosting site for birds that migrate between Australia and the northern hemisphere via the East Asian-Australasian Flyway.
This flyway, another name for a migratory route, stretches from Siberia and Alaska south through East Asia and Southeast Asia to Australia and New Zealand. The flyway crosses 22 countries and measures 25,000 kilometers (around 15,500 miles) each way. More than 50 million water birds travel this route, and they depend on these wetlands and others to feed and rest so that they have enough energy to complete their trip.
The Sanctuary helps to protect threatened bird species such as the curlew sandpiper, ruddy turnstone, red knot, and eastern curlew.
