Summary The IBA of three adjacent islands supports more than 1% of the world population of Crested and Roseate Terns. Further surveys may indicate that other nearby islands may also be important.
Site description The IBA includes three adjacent islands, Pearce islet, Urquhart islet and Hervey Rocks, all north-east of North Island in the Edward Pellew Group of the western Gulf of Carpentaria. Pearce is a large, low vegetated islet. Urquhart is a reasonably large, low, circular, vegetated, rock and coral rubble island. Hervey Rocks is a small, low, partially vegetated rock island with a small sand spit (Chatto 2001 island refs S070, S071 and S072). The IBA may be extended to other poorly-known nearby islands if they are surveyed more thoroughly and shown to support large numbers of nesting terns.
