P.S. to Rob: I carry a crow call when I'm marsh hunting for ducks or field hunting for geese because there are always crows around. If you'll do a little calling when the fowl aren't flying, a lot of the time you'll get a shot. Every duck hunter should kill every crow they have a chance to fire upon, they're a major predator of waterfowl eggs and even the young birds after they hatch.
And, if you like to eat pecans and peanuts! We pile'm up 120 at the time in the pecan orchards. Huge fun with a Super Fox.
