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. 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 the continuing decline in quality of marshy feeding areas, it should be uplisted to Endangered.
