Its not easy for the average joe. I like to get inside of 200 yards and use good glass to look them over real well. I find that many of the boars have a brown muzzle. They have a more squared muzzle and blocky face. They look more bulky in the front, thicker front legs. Big wide head with small ears off to the sides and a crease down the middle.
The sows tend to have black more pointy muzzles and less blocky faces. They tend to be pear shaped with lighter front ends.
Thats easy to say, to write in a book, or put in a a short video. But in the field its not so simple.
They seem to only step out to feed for a little while. Often its just half a minute less than you need to judge them, make the call, then get into position. Then they walk back into the brush just before your ready.
The ones you dont want will stay out feeding forever it seams.
For me #1 is shoot a decent sized boar, never a sow and certainly not a sow w/cubs. After that its all just frosting. Either way your removing a fawn killer.
I look at the hide for rubbing. I prefer a nice hide over a slightly bigger skull. Unless I thought it was 20”, then Id overlook the rubbing.
They seem to rub the tops of their feet, the lower front legs, and sides just behind the front legs, their forehead. These parts will look redish or brownish if rubbed, not jet black.
