There was a lone bird flying near the Wadi Dayqah dam. This was the best I could get before it disappeared. I believe it is the Egyptian Vulture (Scientific name: Neophron percnopterus) also called White Scavenger Vulture or Pharaoh’s Chicken. In case I am wrong, do enlighten me.
From Wiki: Egyptian vultures feed mainly on carrion but are opportunistic and will prey on small mammals, birds, and reptiles. They also feed on the eggs of other birds, breaking larger ones by tossing a large pebble onto them. The use of tools is rare in birds and apart from the use of a pebble as a hammer, Egyptian vultures also use twigs to roll up wool for use in their nest.
