Summary These mudflats support more than 1% of the world population of Grey-tailed Tattler and Pied Oystercatcher, and large numbers of other shorebirds.
Site description This IBA includes the small inshore islands of Darbada, Crocodile, Yabooma, Gananggarngur and Mooroongga, and the coastal fringe of Milingimbi Island. The shorebirds are likely to use other adjacent mudflats including the remainder of Castlereagh Bay but there is insufficient data to map feeding areas off these islands. The adjacent floodplains of the Glyde River have large numbers of waterbirds but the limited data do not qualify this area for IBA status. The IBA is mostly intertidal mudflats with fringing mangroves and samphire (chenopod) shrubland, with some sandy beaches and dunes on some exposed shores.
