Justification of Red List category
There are no confirmed recent records of the species, but at least two unconfirmed records have been reported since 2000 implying that the species may yet still persist in very small numbers. Following the application of new methods for estimating the probability of a species remaining extant, the species is now considered to be extant, although it must have an extremely small population, hence it is listed as Critically Endangered.

Population size: 1-49

Population trend: Unknown

Extent of occurrence (breeding/resident): 204 km2

Country endemic: Yes
