Headshots from a blind are not as difficult as you might think. I have taken a number of birds this way. The key is to get them in close. I usually put decoys out, about 8 yards from the blind. When the bird is at about 10-12 yards, I shoot for the head. I prefer the shot where the bird is at full strut and marching straight in toward me. I love that, I shoot for the base of the neck. I will usually then hit the neck, but if I'm high I'll get the upper neck or head. I shoot Rocket Sidewinder 3 blade 100 gr expandables that open to a 1 1/2" diameter. These heads give you a little bit of wiggle room. I have missed birds completely and have hit at least one a bit lower than I like. Most of those though, were when I lost patience and compromised taking a shot longer than desired. The one that I hit lower, I still was able to recover. The diameter of the broadhead here helped as it was still able to cut into the lower neck and severed the windpipe. I will still shoot a bird that is facing away with the hope of breaking it's back, but I prefer the facing me shot. I will not take any body shots at a bird unless it's the back facing away, otherwise I will always try for the head/neck shots. If you hit the head or neck, they are done for, no worry about losing them at all.
