Arabian Eagle-owl Bubo milesi



Taxonomy

Taxonomic note
Bubo milesi is recognised as a full species separate to B. africanus on multiple criteria following Collar and Boesman (2019). Previously, B. africanus (including milesi) and B. cinerascens were separated (del Hoyo and Collar 2014). Before this, all were previously included within B. africanus following Sibley and Monroe (1990, 1993). Monotypic.

Population justification: The species is locally common (Kirwan and Boesman 2021), although the population has been considered to be as small as 2,000 pairs (Jennings 2010); 800 pairs in Saudi Arabia, 900 pairs in Yemen, 300 pairs in Oman, and an unknown, but small number in the UAE. This roughly converts to 4,000 mature individuals. Given the absence of any pervasive threats, it is possible the population numbers higher; however, to account for the fact that the species procures a localised distribution (per eBird 2022), the population is nevertheless suspected to number less than 10,000 mature individuals, placed here in the band of 4,000-9,999 mature individuals.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
