Here in PA it seems like everyone and their brother blows on crow calls and owl hoots at first light. Over the years where I hunt, these calls have become very unproductive as compared to the early years. I rarely carry a crow or owl call, as you might as well not even waste the room in your vest with them anymore.
Even roosting birds her, they just do not seem to anwser locater calls probably due to hearing them just way tooooo much? As with PA we never had afternoon hunting, although this will be the first year as the last 2 weeks one can hunt all day. Not sure how effective my roosting tactic will be once a lot of hunters are hunting all day? But in previuos years where we had to quit at noon, I actually had much more luck roosting birds by calling them. Some loud cutts just before fly up, worked well at times, then I'd back out knowing he was there where he sounded off. This seemed to be way more effective here than locators, as the birds never had anyone calling to them just before flyup? But now with the start of all day hunting the last 2 weeks, I'm sure it will also become unproductive like the locators, once every Tom, Dick, and Harry is out calling in the evening?
