A juvenile Ruppell's with a more typical griffon here, photographed Sept 2015 at the Algarrobo watchpoint, Algeciras.
Ruppell's to my eye usually has a compact, 'rakish' look about it. The jizz is somehow different.
NB. Other shots in this sequence show that the griffon is a bit lower and therefore closer to the camera than the Ruppell's, so the size difference is a bit exaggerated here.
