Population justification: The population is estimated to number 200 individuals, roughly equating to 160 mature individuals.

Trend justification: Prior to the fire in 2010, the breeding population was stable or increasing slightly (Barov and Derhé 2011); however, the increases in population estimates might likely be the result of increased survey effort (I. Ramírez in litt. 2005). It is too early to determine the effects of the fire in 2010 on the long-term trend of the species. However, despite only one juvenile surviving of the 38 chicks monitored in 2010, the numbers of fledging chicks in subsequent years has been encouraging.
