why do crows chase large hawks ? thanks in advance?

So they don't eat there eggs or babies...

Because the Hawks are predators and prey on Crows, therefore the crows chase them away.

Or if a Hawk has something (as I have once seen) the Crows will want it.

I saw this amazing looking Hawk with something that I think was a Duck. There were a bunch of Crows that kept their distance but continually cawed and watched the Hawk. I thought it was pretty cool.

They don't like them in their territory. Crows are pretty smart. Much smarter than what people think. The Indians used to say that the crows knew the hawks hunted other animals. The crows didn't like that, so they chased them away from their "home area".

The Hawks because I hate Adelaide!!! extremely I nevertheless imagine Hawthorn receives over the line, this is the NAB Cup in spite of the indisputable fact that so some thing can take position. Hawthorn are more desirable efficient on paper yet are youthful and somewhat inconsistent. Crows have a habit of choking in initial Finals in spite of the indisputable fact that, even even if this is the pre-season.

Hawks eat crow babies.

* For the same reason they chase after house cats, and owls; the crows are territorial, and hawks, house cats, and owls are the crows natural enemy.
