Justification of Red List category
The species is classified as Vulnerable because it has a very small range: it nests at just three known sites, with possibly over 95% of all known breeding birds concentrated at one cave. Overall population trends are unclear, but suspected to be stable in the absence of any clear increase or decline. If contraction of its breeding range continues, or populations are shown to be undergoing a continuous decline owing to a decrease in the number of nest-caves, perhaps compounded by continuing decline in extent and quality of marshy feeding areas, it may qualify for a status change.
