Justification of Red List category
This species is confined to one very small island, where its population fluctuates in response to rainfall and appears to reach extremely small numbers. Climate change may increase drought in Cape Verde, adding to the likelihood of extinction. As a ground-nester, the species is highly at risk from the accidental introduction of predators. For all of these reasons, it is classified as Critically Endangered.
