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.
