I once saw a hawk on the ground eating a squirrel it had killed. Another squirrel was watching. It then charged at the hawk, and the hawk was startled. There was a stand off for a bit. The squirrel prepares another charge. The hawk is bewildered. Dashing forwards, the squirrel terrifies the hawk, and the hawk flies off. There was a huge group of us watching it, and everybody figuratively put money on the hawk obliterating the squirrel. One of the coolest animal stunts I've seen in person.
