The Maghreb owl (Strix mauritanica) is an owl of the earless owlgenus, Strix. It occurs in northwestern Africa from MoroccotoTunisia and Mauritania. It was previously considered a subspecies of the tawny owl.
This species is a rather dark grey-brown with no evidence of morph colour variation. It is slightly dull, cooler and more uniform hue overall than Strix aluco alucoorStrix aluco sylvatica.[2][3] Study of genetic materials, including phylogeography, and the species dispersal behaviour, supports the division of Strix aluco maurtanica from the European subspecies, and it may even form its own species, with the Strait of Gibraltar as a natural gap between the ranges.[4] Although sometimes suggested as about 5% smaller than Strix aluco aluco,[5] current data suggest it is of similar size to Italian nominate owls and Spanish Strix aluco sylvatica found on the other side of the Mediterranean.[3] Standard measurements of both sexes are known to be 272 to 305 mm (10.7 to 12.0 in) in wing chord length, 173 to 189 mm (6.8 to 7.4 in) in tail length, 54 to 61 mm (2.1 to 2.4 in) in tarsal length and 28 to 31 mm (1.1 to 1.2 in) in bill length. Weight of males has been reported at 325 to 470 g (11.5 to 16.6 oz) whilst that of females at 390 to 575 g (0.860 to 1.268 lb).[3]
