Why did the crow provoke the cats?

This is a strange video in which a crow provokes and agitates two cats to the point where they fight each other. There is no doubt that the cats were into a territorial dispute anyway. But it seems to me that the crow pushes them both into fighting sooner and more viciously. These cats certainly fought hard and risked serious injury. The black cat is bigger and won the fight. We don't know what happened to the red cat. He may have been hurt.

An animal only does something if it is to his or her advantage. So what advantage is there in having two cats fight over territory? I can think of only one right now having just seen the video.

Cats attack birds as a prey item, as food. If there are two cats in one area the crow has two predators to deal with. If they fight each other, one cat wins and the other leaves the territory leaving one predator for the crow. The crow has an easier life on the assumption that he stays in the area which might be the case as he probably has a source of food there.

Crows are very smart animals and I would have thought that that sort of reasoning is within his or her capabilities.
