If you don't get the odd decent griffon shot at Monfrague, you might as well as throw your camera in the nearest 'embalse'! ;o)
This (presumed male) didn't quite manage to stop in time to join his mate on their rocky doorstep!

The Griffon Vulture is 93 - 122 cm (37 - 48 in) long with a 2.3 - 2.8 m (7.5 - 9.2 ft) wingspan. In the nominate race the males
weigh 6.2 to 10.5 kg (14 to 23 lb) and females typically weigh 6.5 to 11.3 kg (14 to 25 lb). Hatched naked, it is a typical
Old World vulture in appearance, with a very white head, very broad wings and short tail feathers. It has a white neck ruff
and yellow bill. The buff body and wing coverts contrast with the dark flight feathers. [Wikipedia]
