Roadkill can feed a lot of raptors. Eagles, hawks and such.
Speaking of which, I saw a bald eagle the other day.
With the light winter we had last year, there seemed to have been an overpopulation of squirrels over the summer. Which led to much more roadkill. Plenty of food for the crows. I'm sure the crows thrived, and maybe became a little overpopulated themselves.
