Population justification: The population is difficult to measure except in terms of breeding territories. However the breeding system means that the population is larger than the number of territories suggests; for example, the population on Santiago may number 180 adults in the 50 territories, with a total of c.250 individuals (Faaborg 1984). The most recent overall population estimate is 400-500 mature individuals and 300-400 juveniles (T. de Vries in litt. 2000, 2007). Genetic research indicates there is little movement between island populations (Bollmer et al. 2005).
Trend justification: The population is thought to be stable (Jiménez-Utzcátegui et al. 2019).
