Population justification: The breeding population at Bugio has been estimated at 160-180 pairs (Menezes et al. 2010, BirdLife International 2015). Based on these data, the population is placed in the band for 250-999 mature individuals, assumed to equate to c.350-1,500 individuals in total.

Trend justification: The population is suspected to be stable (Ramirez 2008), although the species faces a number of threats and is susceptible to stochastic events and human impacts.
