I made myself a homemade electronic caller and tried it out a few times at the house and crows were going nuts over this thing. At home (choctaw) i had maybe 15-20 crows come in just a matter of a few minutes, but once i got to the lexington public hunting area I couldnt get any to come in to my electronic call. I could hear the crows at a distance, and called in a hawk with the crow distress cry but for the life of me i couldnt get any crows to come in close. After 45 minutes of calling with the electronic call (would call for 10-15 seconds turn the call off for 2-5 minutes and then repeat) I could see one crow at about 250-300 yards that was sitting in a tree but that was the closest thing I had. What gives? I was so excited about being in the woods with my new shotgun but i saw more darn crows at the side of the highway than i did in the woods!
