Justification of Red List category
This species is confined to three small islands where, despite its adaptation to artificial habitats, its population is suspected to be under threat as a result of successive droughts and an increasing human population. Its future on one island, in particular, is precarious, and the overall population trend is uncertain. The discovery of a relatively large population on Fogo, where it occurs commonly in plantations and crops, suggests that it may be less threatened than previously feared, and a re-assessment of its extent of occurrence using a minimum convex polygon means that the species now warrants listing as Vulnerable.
