Ravens

Humorous story from the web:

Researchers for the Western Australian Main Roads Department found over 200 dead crows on the Great Northern Highway recently, and there was concern that they may have died from Avian Flu. A Pathologist examined the remains of all the crows, and confirmed that it was NOT Avian Flu. The cause of death appeared to be from vehicular impacts. However, during the analysis it was noted that varying colours of paints appeared on the bird's beaks and claws. By analysing these paint residues it was found that 98% of the crows had been killed by trucks, while only 2% were killed by cars. The MRD then hired an Ornithological Behaviourist to determine if there was a cause for the disproportionate percentages of truck kills versus car kills. The O.B quickly concluded that when crows eat road kill, they always have a look-out crow to warn of impending danger. They discovered that while all the lookout crows could shout "Cah", not a single one could shout "Truck".
