Diet of the Barn Owl (Tyto alba) (Strigiformes: Tytonidae) in the Saharan Touggourt Area (Algeria)
The Barn Owl, Tyto alba (Scopoli, 1769), is a nocturnal raptor species. Their diet includes small vertebrates, mainly rodents, and birds. To study their feeding in the desert area of Touggourt, we collected 153 pellets at the Ranou palm grove. We found 468 specimens belonging to 62 species. In terms...
