Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). The Cayman Brac subpopulation was estimated in March 2019 at 7,808 individuals (±1,522) and the Grand Cayman population was scheduled to be surveyed in March 2020 (Haakonsson 2020).

Trend justification: There are no data on population trends; however, the species is thought to be declining as a result of habitat degradation. Whilst subspecies crawfordi is highly abundant in the Sister Islands, the species is increasingly clumped in Grand Cayman owing largely to habitat destruction and degradation.
