Taxonomic note
Oceanodroma castro (Sibley and Monroe 1990, 1993) has been split into O. castro and O. monteiroi following Bolton et al. (2008). All Oceanodroma species have since been moved to Hydrobates (del Hoyo and Collar 2014).

Population justification: The population was estimated at 300 pairs in 1999 (Bolton et al. 2008). Recently, the Praia islet population size was updated to 178 breeding pairs, resulting in a global population size estimated at 328-378 pairs (Oliveira et al. 2016). Although the estimate for the population other than Praia islet is now a decade old, the population is not thought to have declined since. The Praia population increased in response to the installation of artificial nest boxes. Thus, the population is best placed in the band 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: Although there is no trend data, the population is suspected to be stable. The population may have even increased since the last known population estimate in 1999 owing to an increase in annual productivity following the installation of nest boxes (Bolton et al. 2008, Bried et al. 2009).
