PRELIMINARY DATA ON THE FEEDING REGIME OF THE JUVENILE PHARAOH EAGLE OWL (Bubo bubo ascalaphus Savigny, 1809) IN THE SEMI-ARID REGION OF OUM EL BOUAGHI (EAST ALGERIA).

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%). [ABSTRACT FROM AUTHOR]

Sunt disponibile puține date cu privire la dieta juvenililor de bufniță-faraon din Africa de Nord. Dieta juvenililor de bufniță-faraon a fost analizată într-un mediu semi-arid în Djbel Tarf (Oum El Bouaghi), care se află în partea de nord-est a Algeriei. Rezultatele se bazează pe analiza a 93 de ingluvii ale puilor, care au fost colectate din același cuib în perioada de reproducere (primăvară), pe parcursul a trei ani succesivi de studiu (2016, 2017 și 2018). Meniul trofic al juvenililor de bufniță-faraon din regiunea Oum El Bouaghi este compus din 5 categorii de pradă, cu abundența relativă a mamiferelor, care ocupă primul loc în cei trei ani succesivi (43,48%, 47,47% și 41,54%); urmează insectele (29,23%, 28,09% ș( 26,70%) și păsările (15,70%, 13,76% și 14,49%). În ceea ce privește biomasa relativă, iepurii (Lepus sp. 35% ≤ B% ≤ 51%) au fost principalele specii de pradă, păsările (Columbidae sp, 17% ≤ B% ≤ 23%) au fost a doua cea mai importantă categorie de pradă. În ceea ce privește abundența, specia de pradă dominantă a fost Meriones shawi pentru cei trei ani de studiu, cu 14,49%, 14,33% și, respectiv, 12,22%. A fost urmat de 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%) și Buthus sp. (5,34% ≤ AR% ≤ 5,76%). [ABSTRACT FROM AUTHOR]
