This vintage wooden crow call, made of walnut I believe, could indeed be used from calling in crows and also for locating turkeys. But, producing such a rich and wonderfully satisfying sound (just blow into the top, like a whistle), I'd be inclined to keep it nearby to use for herding human companions, perhaps in lieu of a dinner bell! Or put it in your pocket and take it to a rally or a sporting event! Plus it is really great looking:)
4 1/4" long x 1 1/8" diameter and in great condition.
