This investigation holds significant merit due to its execution within a region characterized by depauperate avifaunal assemblages in the Western Desert of Egypt. Notably, the study highlights the presence of wild bird populations within petroleum industry worker camps situated in the Marsa Matrouh Governorate.
             The results show that the bird community recorded in the study area was rich in bird species and numerous (8425 individuals), these birds belonged to 16 species, grouped in 16 families and 6 orders. The dominant bird species were western yellow wagtail, house sparrow, rock pigeon, hooded crow, red-backed shrike and Eurasian collared dove. The highest number of bird species was recorded during autumn and then winter season according to the existence of migratory bird species, while the lowest was recorded during spring due to the return of migratory species and bird dispersal for nesting. 
             The bird's members for the order Passeriformes were the most existence than other different orders according to its global distribution, followed by the order Columbiformes in the second rank, then Pterocliformes, Ciconiiformes, Bucerotiformes and finally Falconiformes.
             Autumn season led the other seasons with its highest value for bird richness and Shannon-Wiener diversity index, followed by winter for species richness and spring for Shannon-Wiener diversity index. Spring recorded the lowest value of species richness and summer recorded the lowest value for both Shannon-Wiener diversity index & species evenness.
