Population justification: García et al. (2008) estimate 15,400 singing males in Morocco, while in Spain the most recent estimate suggests around 3,700-4,000 males (Traba et al. 2019). The Tunisian population was estimated to be c.600 singing males in 2007 (Suarez, Garcia and Vinuela in litt. 2020).
Trend justification: Negative trends have been recorded in Spain, with extinctions of local subpopulations occurring during the last two decades (Tella et al. 2005; Traba et al., 2019) and reduced numbers of individuals in extant populations. Recent studies in Spain have recorded declines of at least 40% between 2004 and 2015 (Gómez-Catasús et al., 2018a), equalling a decline of 37% over 10 years, and there is additional evidence of several local extinctions (Suárez 2010, Pérez-Granados et al. 2013a, Pérez-Granados and López-Iborra 2013, 2014, Garza and Traba 2016). Habitat has also been lost or degraded elsewhere in the species's range. In Morocco, 20-30% declines were observed in some sub-populations, but increases were observed in others (J Garcia, 2020, pers. comm.). The overall countrywide trend over 10 years is more likely to be 10-13% reduction (J Garcia, 2020, pers. comm.; N. Lopez-Jiminez, 2020, pers. comm.), but more precise analysis is needed to confirm this (J Garcia, 2020, pers. comm.). In Tunisia, the reduction of habitat from 89,000 km2 to 70km2 between c.1950 and 2007 (Isenmann et al., 2005; Suárez, García and Viñuela, in litt. 2020) equates to a suspected population reduction rate of 55% in 10 years. Hence, declines of 30-49% are suspected throughout the population.
