I saw a huge flock of black crows, the other day. Thet were winging their way down the st lawerence river. I counted a section that was about 100. I estimated that there were over 300 of the black suckers. I was quite impressed. They are smart animals. Where were they going? Probably making the rounds for food sources. The wt thought about them massing together to eat humans only occured a bit later as a comical cultism.
