Summary The floodplains of the Daly and Reynolds Rivers support internationally significant numbers of Magpie Geese, Wandering Whistling-Ducks, Pied Herons and probably other waterbirds including Intermediate Egrets. The IBA also includes the adjacent mudflats of Anson Bay which supports up to 27,000 waders probably including more than 1% of the world's Great Knots. The IBA also supports the near-threatened Bush Stone-curlew and six restricted-range or savanna biome-restricted species.
Site description This IBA consists of all of the adjacent floodplains of the Daly and Reynolds Rivers, which have many waterbird colonies including large numbers of Magpie Geese, and Anson Bay which supports over (unidentified) 20,000 shorebirds. The Downs and Litchfield sections of the Reynolds floodplain are identified as of major importance for breeding and non-breeding Magpie Geese (Parks & Wildlife 2007). The Docherty floodplain, although poorly known, is mapped as having breeding Magpie Geese (Parks & Wildlife 2007), has similar habitat and is included for its inferred waterbird populations and its ecological role within the Anson Bay system. Many of these floodplain species may be attracted by the mixed open habitat whereas most flood plains in the Top End are dominated by solid stands of sedge and reed. The adjacent mudflats of Anson Bay support large numbers of birds from the North Peron Islands to Cape Ford. Waterbird colonies = ref W006, 7, 8, 9, 10, 11, 12, 14, 16, 17, 18, 19, 20, 21, 22, 24, 58, 59 (Chatto 2000).
