| Abstract | From the autumn 2007 to the spring 2008, we studied the diet of the Little Owl Athene noctua in the area of Djanet, situated in the extreme South-East of Algeria. The analysis of 128 pellets enabled us to identify 80 species belonging to 6 classes, 12 orders and 32 families, preyed upon by this raptor. Considering the number of preys, insects (relative abundance, AR = 70.1 %) were dominant, followed by rodents (AR = 17.1 %) ; the most selected ones were Mesostena angustata (AR = 18.4 %) and Brachytrypes megacephalus (AR = 17.4 %). Insects dominated whatever the season (AR = 47 % in autumn, 79 % in winter, 63.6 % in spring). In terms of biomass, rodents were dominant with 9 species, two of them being new for the area. The Little Owl exihibit a diversified diet (E = 0.7) in this Algerian area of Central Sahara |
