Range Description

This species is restricted to Java, Indonesia (BirdLife International 2001). There are confirmed records from four sites in west Java, with likely but unconfirmed reports from five further sites in west, central and east Java. Taking an average colony size of 25 pairs and assuming only one colony per site, this would give a total of under 400 birds for all localities, but this is thought to be highly precautionary and an additional four to five craters may also support the species.
