A recent study has found over 200 dead crows near Colchester, Essex 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 everyone's relief.
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 local council hired an Ornithological Behaviourist to determine the disproportionate percentages for the large truck versus car kills.
The Ornithological Behaviourist determined the cause in short order.
When crows eat road kill, they always set up another crow as a lookout 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."
