Abstract
A power line located 100 km south of Jeddah was monitored for four years (2008-2011) and the results show that collision and electrocution of birds by power lines are of conservation concern in Saudi Arabia. The White Stork (Ciconia ciconia), Common Quail (Coturnix coturnix), Corncrake (Crex crex) and Willow Warbler (Phylloscopus trochilus) were the most affected species in the study area. However, the Common Quail seems to be more susceptible than other species and was found in high numbers. Although the number of species affected is probably low, the increases in energy demands and the introduction of new power lines will lead to an increase in bird deaths by electrocution and collision unless a conservation measure is applied to minimize the effect of power lines especially among the migratory species.
