Most Rüppell’s in Europe are observed in the extreme southern Iberia peninsula, mostly 2cy birds between february and november, but especially during their movements between Senegambia and Spain.
In addition to being a darker and smaller vulture, Rüppell’s characteristics are the pattern of the patagium, the clear margins of the greater and upper tail coverts, as well as the arrow pattern of the body feathers. There are other aspects such as the greater extent of moult, the more triangular head, the reddish neck, etc.
