For a brief period of time in Canada I declared war on the crows, they woke me with their raucous morning b.s. when I was trying to grab few extra zzz's. My neighbor fed them dogfood, they were her pets...I loved the old girl but something had to be done about the crows, which by the way were the Provincial bird and protected. A buddy of mine told me to kill one and hang it upside down on my property where they like to hang out. I practiced with a wrist rocket and marbles and finally drilled one that got to relaxed and let me get within killing range, I hung it upside down and the rest of the crew did not like that one bit and found another place to hang out. Then I started watching them in their antics and it wasn't too long before I declared a truce and cut the dead bird down. They are amazingly smart birds and actually very intertaining to watch, I liked watching them place "king of the tree top" and found watching them stand in an ant hill placing ants on their bodies very interesting, it seems they use the ants that produce formic acid to rid themselves of fleas, one of very few animals that use a symbiotic relationship with another critter to help themselves out. Of course we had the larger ravens as well but they stay quite solitary in contrast to the crows mobbing tendency, they are acrobatic geniouses besides being smart as a whip. We had one crow that used to perch by the deck overlooking the lake, he would call out "go home", in a murmering tone...we called him go home. I've been told that crows have a working vocabulary of about 25 words and everyone of them has a name. A buddy of mine that used to kill alot of coyotes and bobcats told me that once he mastered the "come and get it" call that is used by crows to announce to others that there is something worth checking out that his kill ratio about doubled as opposed to using the dying rabbit call.
