Griffon vultures together on the cliffs... (Gyps fulvus)

The griffon vultures were all over the place today, groups of eight soaring in the skies, lone birds cruising overhead, and yet some chose to relax on the sheer cliffs of Barranc del Sinc.
Here is an image of a massive vulture arriving to roost with another vulture in the shadow of the enormous cliffs, protected by a massive overhang, a vertical drop of at least a hundred meters, and the fearsome bulk and claws and beak of the enormous, majestic birds. I don't think even an eagle owl would attack them at night, in the interest of its own safety...
This place is safer than a bunker. no predator would risk scaling that cliff, and any attacker from the air would be no match against the almost three-meter wingspan of a griffon vulture. In Spain, there are only two which are bigger, all of which are scavengers: the lammergeier, and the colossal black vulture.
