The Port Hedland Saltworks Important Bird Area is a 103 km2 tract of originally intertidal land, now containing a saltern, about 20 km east of the port of Port Hedland. The site regularly supports over 1% of the world populations of red-necked stints and sharp-tailed sandpipers, as well as a population of the range-restricted dusky gerygone. Species that have strongly declined since the 1980s are broad-billed sandpipers, Asian dowitchers, curlew sandpipers, red-necked avocets, banded stilts, Oriental plovers, Oriental pratincoles and white-winged black terns. Other species present include Australian bustards, bush stone-curlews, western bowerbirds, painted finches and canary white-eyes.
