Population justification: The population is estimated to number 130-160 individuals, roughly equating to 90-110 mature individuals.
Trend justification: Prior to the 2010 fires, the breeding population was stable or increasing slightly (Barov and Derhé 2011); with recent increases in population estimates likely the result of increased survey effort (I. Ramírez in litt. 2005). It is too early to determine the effects of the 2010 fires on the long-term trend of the species. However, should new studies reveal the population to be decreasing, the species's status would need to be reassessed.
