El Cancho de La Bola, where my vultures perch - but few on that day.

The white, guano-stained, rock up above, is where I creep up to as quietly as I can to take photos of the Griffon vultures that normally occupy this place. it is estimated that this huge precariously sited boulder is so white because Vultures have been here since the end of the last ice age, therefore 8 - 10,000 years. Enough time for a serious staining problem to develop!
Sierra de La Cabrera, Madrid Province.
Also, one of these granite hot heads is going to get red-carded for a head butt soon, probably both of them!
