- Abstract
Few data are available on the diet of the juvenile Pharaoh Eagle Owl in North Africa. The diet of the juvenile Pharaoh Eagle Owl was analysed in a semi-arid environment in Djbel Tarf (Oum El Bouaghi) which is located in the North-Eastern part of Algeria, through the analysis of 93 rejection pellets of juveniles that were collected from the same nest during the breeding period (spring) during three successive years of study (2016, 2017, and 2018). The trophic menu of the juvenile Pharaoh eagle-owl in the region of Oum El Bouaghi is composed of 5 prey categories with a relative abundance of mammals occupying the first rank during the three successive years (43.48%, 47.47%, and 41.54%); followed by insects (29.23%, 28.09%, and 26.70%) and birds (15.70%, 13.76%, and 14.49%). In terms of relative biomass, lagomorphs (Lepus sp., 35% ≤ B % ≤ 51%) were the main prey species, birds (Columbidae sp., 17% ≤ B % ≤ 23%) were the second most important prey . In terms of abundance, the dominant prey species was Meriones shawi for the three years of study with 14.49%, 14.33%, and 12.22% respectively. It was followed by Jaculus orientalis (8.70% ≤ AR % ≤ 11.80%), Gerbillus campestris (8.45% ≤ AR % ≤ 11.24%); Oryctes nasicornis (6.11% ≤ AR % ≤ 8.45%); Tapinoma sp. (5.24% ≤ AR % ≤ 8.45%); Passeriformes sp. (5.62% ≤ AR % ≤ 7.49%) and Buthus sp. (5.34% ≤ AR % ≤ 5.76%).
