Population justification: Figures point to a total of 15,337-30,519 pairs, roughly equating to 46,000-92,000 individuals, based on a population assessment covering the species's entire range (Derhé 2012). However, this number is at odds with preliminary counts conducted in early February when c. 75,000-90,000 individuals have been recorded migrating through the Bosporus [J. Tavares and D. Sahin. in litt. 2012, D. Sahin in litt. 2015]), at a time when most breeders are already around their colonies in Malta, France, and Italy. More surveys are urgently needed to confirm breeding population sizes, particularly in the Aegean Sea and in Turkey.
Trend justification: Extremely low breeding success has been reported at several important colonies, particularly in Italy (Baccetti et al. 2009), as well as adult survival probabilities (across the western Mediterranean) that are currently too low to maintain stable populations (Oppel et al. 2011). There is evidence of both recent and historical colony extinctions, with eleven colonies having been reported extinct in the last 60 years (Bourgeois and Vidal 2008, N. Baccetti in litt. 2011, Cadiou 2015). The trends of populations in Albania, Algeria, Bulgaria, Croatia, France, Greece,Turkey and Tunisia are currently unknown. Declines are suspected in Croatia (for at least one colony [I. Budinski in litt. 2011]) and Greece (based on long-term trends [J. Fric in litt. 2011]) however the Greek population was reported as stable according to the European Red List of Birds (BirdLife International 2015).
It has been reported that the species is declining in Italy by 10-50% over 13 years (N. Baccetti in litt. 2011), in France by 6% per year (Oppel et al. 2011) and in Malta by 0-15% over nine years (Borg and Sultana 2002, Raine et al. 2009, Sultana et al. 2011). In total, these three countries represent around three-quarters of the known global population. By combining data for these three countries it is predicted that, if the species continues to decline at the current reported rate, the global breeding population will decrease by more than 30% in the next 54 years, i.e. three generations (Derhé 2012). These declines are retained despite increases reported for Italy and Malta in the 2015 European Red List of Birds (BirdLife International 2015). The reported increases may be either dependent on the trend at one colony or may be a result of better knowledge rather than real increases. Consultation with experts in the relevant countries suggests that overall the negative trends should be retained for the current assessment. However should new information suggest that these populations are experiencing genuine increases the global trend direction should be amended.
