Important Findings About Crow Mortality Rates
Researchers for the Maine Turnpike Authority found over 200 dead crows near
Bangor, Maine recently, and there was concern that they may have died from
Avian Flu. They had a Bird Pathologist examine the remains of all the crows,
and, to everyone's relief, he confirmed the problem was definitely NOT Avian
Flu.
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. Maine then hired an
Ornithological Behaviorist to determine the cause of the disproportionate
percentages for truck kills versus car kills.
The Ornithological Behaviorist determined the cause in short order: When
crows eat road kill, they always have a look-out crow in a nearby tree, to
warn of impending danger.
His conclusion was that, while all the lookout crows could say "Cah", none
could say "Truck.
