The diet of the Atlas Flycatcher, an endemic bird species of North Africa is studied in Northeastern Algeria in the forest of Guerrouch in the Taza National Park. The diet analysis was based on the examination of the faecal sacs of the nestlings (n=150) collected in nest boxes installed in a mixed formation of Algerian oak and African oak (Quercus canariensis and Quercus afares). A total of 854 food items were identified, representing 49 prey taxa. The analysis of centesimal frequencies by class revealed the clear dominance of Insecta with 85.12%, followed by Arachnida 13.34%, Gastropoda 1.28% and Malacostraca 0.23%.
