Taxonomy

Taxonomic note
Puffinus lherminieri (incorporating baroli), P. bannermani, P. persicus, P. subalaris and P. bailloni (del Hoyo and Collar 2014) were previously lumped as P. lherminieri and baroli was subsumed under P. assimilis, following Brooke (2004), before which P. bannermani and P. persicus where split following Sibley and Monroe (1990, 1993).

Population justification: The nominate subspecies has been estimated to number 7,400-20,500 pairs (Mackin 2016), with subspecies boydi estimated at 5,000 pairs on the Cape Verde Islands, and subspecies baroli numbering 895-1,741 pairs on the Azores (BirdLife International 2015), c.1,642 pairs in the Madeira region (BirdLife International 2015) (most recent estimate of c.300 pairs in the Desertas Islands, 1,500-2,200 in the Savage Islands [reviewed by Brooke 2004]) and c.400 pairs and declining in the Canary Islands (Rodríguez et al. 2012, BirdLife International 2015). Overall, this implies that the total population size includes more than 30,000 mature individuals, up to potentially 58,570 mature individuals. The population size is therefore placed in the range 30,000-59,000 mature individuals.

Trend justification: The population is suspected to be in decline owing to the impacts of introduced species. The European population size is estimated to be decreasing at a rate approaching 10% in 66.9 years (three generations) (BirdLife International 2015), and also the Caribbean population appears to have undergone declines, at least historically (Mackin 2016).
