Justification of Red List category
Despite several ornithological surveys in suitable habitat by professional ornithologists and a good number of park employees, the species has not been recorded since 2001. Extensive habitat loss has occurred in the region, and the remaining fragments are small and isolated. Any remaining population is likely to be tiny, to have an extremely small range, and to be declining. For these reasons, the species is listed as Critically Endangered. Following the application of new methods for estimating the probability of a species remaining extant, the species is now considered to be Possibly Extinct.

Population size: 0-49
