Summary This IBA covers the world range of the Ogea Monarch (VU) which inhabits forest on three small islands. This is a remote and poorly known island group.

Site description The IBA covers the entire range of the Ogea Monarch: the two principal islands of Ogea, Ogea Levu and Ogea Driki (13 km2 and 5 km2 respectively, 2 km apart), and the smaller island of Dakuiyanuya (immediately adjacent to Ogea Levu).  These are raised coralline islands.  

Key Biodiversity This IBA has six endemic subspecies which are restricted to the Lau group or other small islands in the south of Fiji and are not included in any other IBAs. The Blue-crowned Lory is also restricted to the South Lau group within Fiji but is more widespread around Tonga and Samoa. A1 Globally threatened species * Ogea Monarch (VU) – entire world population A2 Restricted-range species 11 species (out of 36 in Fiji), including the Blue-crowned Lory which is not in any other Fiji IBA.

Non-bird biodiversity: No surveys have been undertaken.
