|When Canadian road workers found about 200 dead crows on the highway between Toronto and Hamilton, there was concern that they may have died from Avian Flu.|
So the government had a bird pathologist examine the remains of all the crows and he confirmed the problem was definitely not Avian Flu, much to everyone's relief.
However, he was surprised that his detailed study determined that 98 percent of the crows had been killed by impact with trucks, but only 2 percent were killed by car impact.
The Province then hired an Ornithological Behaviourist to determine the reason behind the disproportionate percentages for truck versus car kills.
The Ornithological Behaviourist determined the cause in short order. When crows eat road kill, they always set up a lookout crow in a nearby tree to warn of impending danger.
His conclusion was that the lookout crow could warn "Cah", but he could not say "Truck".
