Population justification: The population is assumed to be tiny (fewer than 50 mature individuals) based on a lack of records since the only specimen was collected in 1953 (Dickinson et al. 1991, Collar and Lambert 2013, Allen 2020). Applying the methodologies of Keith et al. (2017) and Thompson et al. (2017), Butchart et al. (2018) determined that the probability of the species being extinct was 0.14 (0.00-0.27) based on records and surveys, and 0.04 (0.01-0.1) based on threats. Accordingly it is classified as Critically Endangered, rather than Extinct (see Akçakaya et al. 2017), in large part because there has not been substantial survey effort on Panay, where the species could conceivably occur on biogeographic grounds.

Trend justification: Unknown in the absence of certainty that a population persists.
