Population justification: The population is unlikely to number more than a few thousand individuals based on recent records and surveys. It is placed in the band 2,500-9,999 mature individuals here, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: This species's population size and trends are unclear but it appears to have declined and become increasingly fragmented since the mid 20th century, becoming uncommon in the central mountains. Based on this information, the species is suspected to be suffering a moderate and on-going decline overall.
