Well, it is not a pretty story.... about 200 dead crows near Halifax, and there was concern for Avian Flu. They had a Bird Pathologist examine the remains of all the crows, and he 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 car impact. The Province then hired a
Ornithological Behaviorist to determine the disproportionate percentages for truck versus car kill.

The Ornithological Behaviorist determined the cause in short order. When crows eat road kill, they always post a "look-out Crow" in a nearby tree, to warn of
impending danger.


His conclusion was that the lookout crow could say "Cah", but he could not say "Truck."

True this + not humor,sorry.I shoot crows over a pecan orchard in the fall (duh!).They do post lookouts + the key to a large yield is to wound the lookout,not kill.The other crows will then converge on the lookout + attempt to peck him/her to death. No doubt to betrayal for not doing the job.meanwhile one has an abundance of shot opportunities.It works.
