A survey of bird species richness was conducted at three sites in Wadi Al-Arj, north of Taif, Saudi Arabia. Each site was visited once every two weeks during the period November 2022 - May 2023. Eighty-one species of birds belonging to 31 families were recorded during the autumn, winter, and spring seasons. The list included 33 resident species of which 6 were endemic and 2 were semi-endemic species to the Arabian Peninsula, as well as 48 migratory species. The total recorded population consisted of 2220 birds, with the House sparrow (Passer domesticus) being the most abundant species representing 15% of the total population density followed by the Laughing dove (Spilopelia senegalensis), the Rüppell's weaver (Ploceus galbula), and the White-spectacled bulbul (Pycnonotus xanthopygos). It is recommended that the Wadi Al-Arj region receives environmental attention, particularly the reed beds and other places that are significant bird habitats.
