Well, it is not a pretty story.

About 200 dead crows were found near the city of Regina and there was concern for Avian Flu.

They had a Bird Pathologist examine the remains of all the crows, and he confirmed the problem was definitely NOT Avian Flu, to everyone's relief.

However, he determined that 98% of the crows had been killed by impact with trucks, and only 2% were killed by cars.

The Province of Saskatchewan then hired a Ornithological Behaviorist to determine the disproportionate percentages for truck versus car kill.

The Ornithological Behaviorist determined the cause in short order.

When crows eat road kill, they always post a "look-out Crow" in a nearby tree, to warn of impending danger.

His conclusion was that the lookout crow could say "Cah", but he could not say "Truck."
