Population justification: The population size was estimated not to exceed 1,000 birds by (Harrap 2002). With the discovery of the additional two sites, it is now estimated that the population size could be between 500-1,000 breeding pairs (Haddad and Afoutni 2019). It is therefore placed in the band 1,000-2,499 mature individuals, but the upper estimate is closer to 2,000 mature individuals.

Trend justification: This species has a high forest dependency. Between 2009-2019, its range experienced a forest loss of 6.1% (Global Forest Watch 2020). Additionally, declines in density have been observed in its stronghold on the Guerrouch massif. In 1991, densities of 2-3.1 pairs per 10 ha were found by Bellatreche (1991) (as reported by Moulai et al. 2017), whereas in 2016, densities of 1-2 pairs per 10 ha were found by Moulai et al. (2017). The population is therefore inferred to be declining. 

The reduction in population densities reported by Moulai et al. (2017) equates to a decline of 35-50% over a 25-years period, which equates roughly to a rate of decline of 15-25% over ten years. The rates of decline at the other sites is unknown, however it is likely to be declining at a higher rate than forest loss alone (which would equate to <10%). Due to uncertainties, the overall rate of decline is precautionarily placed in the band 20-29% over ten years.
