It always amazes me the fortitude and courage it takes small birds to stand up to a much larger bird. The smaller bird knows it can be eaten, but dive-bombs the predator. This behavior is known is "mobbing" and is typically done in attempt to drive the predatory bird out of a breeding territory or nonbreeding territory, to protect its nest/young or its food source. Mobbing is used to drive a predator away instead of harming them.
The smaller birds are usually more agile and can quickly get away when mobbing a large bird. The larger bird may flee instead of expending so much energy to chase the small bird.
