I read about a professor who carried out studies on Carrion Crows, the study was that a lot get killed by heavy vehicles rather than cars.
This got me interested so I did a study of my own, I traveled down some country lanes till I saw a carcass on the road, so I set up a hide and waited.
I didn't have to wait long, some crows came swooping down and started to pick at this dead animal, then I noticed something. They post a lookout to warn them of oncoming vehicles, when a car was coming the lookout started to squawk "KAH, KAH," and the all scattered till the car had passed.
This happened a few times, then I noticed a large lorry coming and not a sound from the lookout.
As the lorry was almost on them they scattered but it was a near miss.

So after my studies I realised the crows hadn't learned how to say "Lorry" or "Truck" and this is why they get more killed by heave vehicles.

I submitted my findings to the Royal Society for the Protection of Birds but as yet not had a reply.

Speaking of scavengers, (seriously that is,) why haven't vultures learned to drag their meal out of the road? My chickens know how to carry food items in their beaks, why do vultures stand in harm's way, picking at sometimes rather small roadkill, having to fly off over and over; this is a mystery to me....

Yeah, that has occured to me as well. I hit one with my van once, put a nick in the hood. It was too slow getting off the road.
