English: Carrion Crow (Corvus corone) Apart from the Raven the Carrion Crow is the largest member of the Crow family. Unlike Rooks, which live together in large numbers, Crows live either in pairs or in threes. Where I live for years there have always been three Crows – I think it is better to chase away the Magpies, who sometimes come and try to take over, if there is an extra bird to help.

Researchers for the Massachusetts Turnpike Authority found over 200 dead crows recently, and there was concern that they may have died from Avian Flu. A Bird Pathologist examined the remains of all the crows, and, to everyone’s relief, confirmed the problem was definitely NOT Avian Flu. The cause of death appeared to be vehicular impacts.

However, during the detailed analysis it was noted that varying colors of paints appeared on the bird’s beaks and claws. By analyzing these paint residues it was determined that 98% of the crows had been killed by impact with trucks, while only 2% were killed by an impact with a car.

MTA then hired an Ornithological Behaviorist to determine if there was a cause for the disproportionate percentages of truck kills versus car kills.

The Ornithological Behaviorist 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 lookout crows could shout “Cah”, not a single one could shout “Truck.”
