Population justification: Young (2008) estimated a population of 3,100 individuals on Montserrat. The species is considered rather rare elsewhere, and is probably best placed in the band 2,500-9,999 mature individuals. This equates to 1,667-6,666 individuals in total, rounded here to 1,500-7,000 individuals.
Trend justification: There are no new data on population trends; however, the species is suspected to be declining, although following the cessation of volcanic activity on Montserrat, not as fast as previously.
