We duck hunters can be a hard headed breed, and tend to do the same thing if it worked once before but improvements can be made. My improvement in 2017 was to work harder at concealment. Funny how we are concerned about the quality of paint and realism of a tiny decoy, but then think, "That pea brained bird won't see my big white face, box of shells, shotgun, or dog sitting right here." I used to think tucking my head down and wearing a billed hat would conceal my bearded face just fine, face paint was just weird and extreme. My friend (that wears face paint) asked me why I tucked my face when the birds were coming in. I gave him the 'are you stupid look?' and said, "why do you think?" He replied, "If you can understand that birds can see your dumb face, why can't you understand that covering it with camo paint would help hide it? I tried to argue a little because thats what a duck hunter does, but his points were adding up and mine weren't. He claims ducks see farther, and pick up on movement extremely well, so when my face is up looking for a duck, they see it before I see them, then I make it worse by moving my head down to "hide". I started face painting and its a better way. You can have your eyes on the sky a little more and it makes things easier and more enjoyable. Following that experience, I've been working much harder at all forms of concealment and its really paid off. Some days it wouldn't be necessary because I would have had a limit anyhow, but it sure seemed to help pull in birds on the marginal days. I always thought my hiding skills were sufficient, but really trying to improve them paid off. What lesson did you learn in 2017, or what skill do you want to improve in 2018?
