RE: Crow Calling
Crows can be some real fun during the off season. I mostly use a mouth call, but have had success with a homemade e-call. Anytime is a good time to call them except after dark. I have never used decoys, but have read alot about using decoys, food items, and ketchup to mimic blood stains on snow. If you can kill the first bird that flys by (the scout) sometimes the others will follow, and it can be some real fast shooting.
Be sure to use good camo, and don't move. Crows are like aerial turkeys they can see really well. One thing I've found is that after the first few pass bys they start to fly higher and out of range. So, get in a good shot while you can. I don't hunt them anymore because during the spring they have caused more than one gobbler to loose his head!
