Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996). The population size on Santa Cruz in 2008 (largely confined to higher altitudes) was estimated at c. 12,000 singing males (Dvorak et al. 2012).
Trend justification: The population had been suspected to be stable in the absence of evidence for any declines or substantial threats. However a recent study by Dvorak et al. (2012) used quantitative census data to describe the distribution and abundance of the land birds of Santa Cruz, the second largest island in the Galápagos archipelago. The results revealed that the species had declined significantly between 1997 and 2010, with declines of >65% in the dry zone, >20% in Scalesia forest and >50% in the agricultural zone. Changes in insect abundance or availability could be driving the decline, although other factors such as habitat alteration and introduced species may also be influencing declines (Dvorak et al, 2012). No census data currently exists for the islands of Isabela and Santiago but given the level of habitat destruction and degradation by introduced herbivores on those islands (Henderson and Dawson 2009), similar declines are suspected.
