Jimmy in any antlerless program a few buttons will be popped from time to time. But with practice and a little " attention to detail" you can all but prevent it. Shooting only mature does of course is the safest method. But what about those 2 " does" standing 300yds away and they are the only deer you see? It simply takes great optics to make 100% sure and you cant always kill, despite the urge. I' ve found that when looking at long ranges at buttons that you will notice that " roundness" that is found only on fawns vs does & bucks. Their heads are round, their ears are round and their jaws/nose' s are just more " rounded" in appearance than does. A does jaw/nose, ears and body will be much longer in appearance than a fawns.

As for seeing them during bowseason, sometimes you can see the little black " dots" above the eyes that indicate a button but sometimes I' ve seen female fawns with dark " swirls" of hair that could be mistaken for buttons as well. This is why I just wont shoot fawns unless its very late in the season and they practically walk underneath me (but typically by that point we are through with " doe poppin" ).

Buttons should be protected at ALL costs, you could be preventing the killing of a lifelong " raghorn" or it could be the next B&C in the books you just dont know! This past season on a 2k acre farm I hunt here in west Tn, we killed 40 does and none of them were buttons. This is a first in our history. Typically as many as 3-5 " antlerless" deer killed each season would mistakenly be buttons.

It just takes patience, good optics, practice and the commitment NOT to shoot " does" until you are 100% sure.
