Pesky crows a drudgery for hawks?

I watched today as a pair of crows harassed a Rough-legged Hawk as it was heading southward, over King Township.   The hawk did make several evasive manoeuvres but otherwise seemed to take it in stride.   The encounter was short-lived and all the parties moved on.   However, I was left wondering how many times this happens to the hawk as it migrates from Canada's Arctic to the southern United States.   And in the far north, the protestors would be Ravens, a bird that is the same size, or even slightly bigger, than the Rough-legged Hawk.   The migrant raptors are probably harassed off-and-on all the way south.   And I thought all they had to do was just keep flying.   Please comment if you wish.
