I was walking to the Crater Shul for Minchah on Erev Yom Kippur. Approaching the door, which backs up to a large park near the crater's edge, I encountered a herd of mostly young Ibex, tensely gathered together over what looked like some delectable treat on the ground. Several young males were contesting for it, as a sage veteran looked on, when all of a sudden the elder of two young Ibex started head-butting the younger away from the treat which he claimed for himself, apparently with the approval of the elder looking on. It is amazing to see how quickly the head butts come, just as it is amazing to see how quickly the Ibex can disappear up or down a vertical wall.
