If the ravens took off from the side of the road, they were probably dining on road-kill when you interrupted them.
Glad you weren't hurt (sore shoulder doesn't count); that could easily have been much worse. Buy a lottery ticket, it's your lucky day.
Years ago I was doing maybe 60 when a turkey vulture rose up off a dead deer on the roadside. It crossed in front of me and would have made it, but dove down at the last moment (I later learned this is common behavior). It hit my headlight, then windshield, finally my helmet and left blood and other bits on all... Luckily all I got was a headache and an opportunity to clean up the bike. Popped a couple plastic bits off the helmet, but I found them.
Be careful out there...
