Population justification: An estimated 500-1,000 pairs breed on the Cape Verde Islands (Hazevoet 1995, Ratcliffe et al. 2000), although this must be regarded as an absolute minimum, as further colonies probably exist on Fogo and Santa Antão, and individuals have also been observed breeding in the central mountain range of Santiago Island (Ratcliffe et al. 2000) and in the PN Serra Malagueta (Santiago). Until further data are available, the population is estimated at 1,000-2,000 mature individuals, assumed to equate to 1,500-3,000 individuals in total.

Trend justification: Although a further analysis is necessary to assess the current population trend, preliminary results of data collected on Fogo reflect a decline due to a number of threats, which are likely to be similar in the four breeding islands since all of them are inhabited by rural communities (Militão et al. 2016, 2017).
