I would say not being on the "x". We found this year by watching and really paying attention to the first few birds that would come in would give you an indication if you were there or not. Sometimes seemingly minor adjustments in the blind location or decoy placement made big differences in how well birds would commit. After hunting some of the same spots for several weeks, birds get used to it and like to see something different.

Also I had to put a headnet on my son in the beginning of the season, he simply couldnt get through that if you look straight up at birds circling straight overhead, they would flare never to be seen again. He got much better towards the end of the season and definitely gets it now.

Also agree with what you guys said, lots of poor callers out there, and other than a few soft quacks is about all I do. Poor hide saves many lives as well.
