Population justification: Surveys carried out between 1999 and 2008 suggest that the population numbers fewer than 250 pairs (Porter and Suleiman 2014), thus there are probably fewer than 500 mature individuals. It is placed in the band 380-750 individuals in total, with a mature population likely numbering between 250-500.

Trend justification: The species faces a number of threats including capture for the falconry trade (Porter and Kirwan 2010), which is resurging following the limited implementation of wildlife laws due to the civil war and related conflict (A. Saeed Suleiman and K. Van Damme in litt. 2020), road construction, wood collection, overgrazing, and impacts from climate change on habitat (A. Saeed Suleiman and K. Van Damme in litt. 2016). As such, the population is suspected of declining, although the exact rate has not been determined.
