Approximately 200 dead crows were recently found near Northam on the Great Eastern Highway in West Australia and there was concern that they may have died from Avian Flu.
A Bird Pathologist examined the remains of all the crows, and 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 an impact with a car.
The Federal Government then hired an Ornithological Behaviorist to determine the dis- proportionate percentages for truck versus car kills.
The Ornithological Behaviorist determined the cause, the conclusion in short order was:
When crows eat road kill, they always set-up a look-out Crow in nearby tree to warn of impending danger.
His conclusion was that the lookout crow could say "Cah" but, he could not say "Truck."
