Spending one day in the zoo of Duisburg, Germany, I also saw two majestetic Eurasian griffons (or griffon vultures I've got no clue about the difference). It was hard to take pictures without the fence in the foreground, especially when the bigger one jumped down a tree stump and beat his wings.
I had no idea before... these birds are HUGE!!
