Didn't know you needed a fishing licence for crows.This post was for informational purposes and not to be taken literally.They wern't out to make friends with the crows rather body count.Electronic calls and decoys arn' legal in some States/Provinces.The US Gov't coyote control also used a .32 cal round that fired a cynide capsul into the coyotes mouth when they pulled on the bait.Set guns for polar bears [Norway]etc............These are things that happened not condoned..................Harold
