Taxonomic note
Calonectris diomedea and C. borealis (del Hoyo and Collar 2014) were previously lumped as C. diomedea following Sibley and Monroe (1990, 1993), which was also formerly lumped with C. edwardsii following Hazevoet (1995), contra Brooke (2004).

Population justification: The most recent assessment of the European population provided an estimate of 30,500-48,100 pairs, equating to 61,000-96,000 mature individuals (BirdLife International 2015). The largest colony on Zembra Island, Tunisia, is estimated at 113,720-176,750 pairs (Defos du Rau et al. 2012). The global population has been estimated at 142,478-222,886 pairs (Defos du Rau et al. 2012, Derhé 2012, Carboneras et al. 2013), assumed here to be equivalent to c.285,000-446,000 mature individuals.
Trend justification: The overall population trend is estimated to be declining. The species’s population is estimated and projected to be declining by c.2% over three generations (1980-2038), although this is based on data from only 6% of the population (Derhé 2012, Carboneras et al. 2013). The European population is estimated to be declining by less than 25% in three generations (BirdLife International 2015). Estimates of adult survival and breeding probabilities in Tunisia are required to fully estimate the global population trend (Carboneras et al. 2013).
