A recent Alberta Government study, has found over 200 dead crows near
Calgary, Alberta and there was concern that they may have died from the
Avian Flu virus. A Bird Pathologist examined the remains of all the
crows, and he confirmed the problem was definitely NOT Avian Flu, to
However, he was also able to determine that 98% of the
crows had been killed by impact with large trucks, and only 2% were
killed by car impact.
The Provincial Government hired an Ornithological
Behaviorist from Toronto to determine the disproportionate percentages
for the large truck versus car kills .The Ornithological Behaviorist
determined the cause in short order. When crows eat road kill, they
always set-up a look-out crow in a nearby tree to warn of impending
His conclusion was that the lookout crow could say "Cah", but
he could not say "Truck."
