Population justification: The global population size has not been quantified, but the species is described as data deficient and potentially already extinct (del Hoyo et al. 2006): alternatively the type specimens may represent aberrant individuals of another species or potentially hybrid taxa.

Trend justification: The population trend is unknown as this species has not been located in its known range since 1972 (del Hoyo et al. 2006).
