Dead Crows?

[ausfost]

Well, it is not a pretty story....
About 200 dead crows were found near Weymouth, 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 car impact.
The Council then hired an Ornithological Behaviourist to determine the
disproportionate percentages for truck versus car kill.
The Ornithological Behaviourist 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."
