English: Griffon vulture in flight. The photo was taken at Carmel mount in Israel. There is a nature reserve on that mount, where they keep some captive vultures in cages (many Griffon vultures, some Egyptian vultures and to the best of my knowledge a pair of Lappet-faced vultures). Vultures in cages are used as a breeding kernel: as soon as these captive birds bring a new chick, the chick is taken away from them, treated and raised in a way it doesn't get imprinted to humans and is released to the wild. So this way they create a wild population of birds. However, vultures that are raised this way get a wing tag as well - so people from the ground could see who's flying and keep their records. So I assume that this specific one (without wing tags) is of European origin: it flew here for the winter and joined the local flock.
