Bird Research

Researchers for the Massachusetts Turnpike Authority found over 200 dead crows near greater Boston recently, and there was concern that they might have died from Asian Flu.
A pathologist examined the remains of the crows and to everybody’s relief confirmed the problem was definitely not Asian Flu.
The cause of death appeared to be vehicular impacts.
However during the detailed analysis colours of paints appeared on the bird’s beaks and claws.
By analysing these paint residues it was determined that 98% of the crows had been killed by impact with trucks while only 2% were killed by impact with a car.

MTA then hired an Ornithological Behaviourist to determine if there was a cause for the disproportionate percentages of truck kills versus car kills.
He very quickly concluded the cause. 
When crows eat road kill, they always have a look-out crow in a nearby tree to warn of impending danger.
They discovered that while all the look-out crows could shout “Cah”
Not a single one could shout “Truck”
