RE: locator call
They can work,maybe not all the time or under any circumstances, but they do work. I just use my own voice to owl hoot and don't overdo it at all, onceI get a response I stop so it will work the next day (so they don't get USED to it). One spring I wasn't hearing anything and let out a couple hoots only to be answered by another owl LOL. We talked back and forth a bit and eventually got a gobbler to sound off (ended up the real owl was right near me in a tree).
