Brown Hyena chases Leopard into a tree

Brown Hyenas are usually very timid animals… never would I have thought that they will show any kind of aggression towards leopards. Being a smaller female leopard, she is completely out-weighed by a much bigger Brown Hyena. As the hyena approached, he indicated his intentions by raising his hair. Unfortunately I lost the action near the end - not perfect but a worth-while moment to share.
