Population justification: In 1998, the species was estimated at 8,200-14,700 individuals (Rosselli 1998); however, this estimate was considered preliminary, as the methodology did not account for detectability differences between habitats nor for the effective population percentage (Gómez-Montes 2011). A population of 8,200-14,700 individuals roughly equates to 5,500-10,000 mature individuals. To account for a potential overestimation of the population size, it is here placed in the band 2,500-9,999 mature individuals. This number may need to be corrected if a more detailed population estimate becomes available.

Trend justification: There is no current evidence for significant declines in the area of suitable habitat available, or of changes in abundance. Thus, the population is suspected to be stable.
