Population justification: The species's global population is estimated at 530-540 breeding pairs, equating to 1,060-1,080 mature individuals (BirdLife International in prep.), which is assumed to be indicative of a total population of c.1,600 individuals.
Trend justification: The population has been increasing since recovery efforts started in the late 1960s (Mateos et al. 2021). It is estimated to have increased by c.167% between 2007-2018, with a long-term (1980-2018) increase of c.500% (BirdLife International in prep.), although the population now appears to have reached a plateau (S. Cabezas-Díaz in litt. 2020). The species recolonised Portugal in 2003, where it has been slowly increasing since, with six breeding pairs recorded in 2011, nine in 2012, 16 in 2016 and 17 in 2019 (S. Cabezas-Díaz and J. C. Atienza in litt. 2016; S. Cabezas-Diaz in litt. 2020).
