RE: Squirrel's effect on deer.
i agree with frizz on this one. i believe squirells can help and hurt your hunt. learning from my time in the stand, it seems wildlife "feed" off of each other. i have watched squirells "bark" at deer for eating "their" acorns on the ground and did not bother the deer.
on the other hand, if you have ever been busted by a squirell sitting in your treestand you know they will "bark" at you for what seems to be forever. i think deer know that if it's not them being barked at, that there's something wrong and will not come towards the "barking" squirell. just a thought...because i have never seen deer in my stand while a squirrel was barking at me.
i have seen deer while hunting thanks to the squirells "barking" at them and letting me know where the deer was. i would have never seen the deer if i wouldn't have turned around to see what the squirell was so pissed off about.
this is just my theory, so next time your in the woods hunting and you hear a squirell "barking" and you know he's not "barking" at you...keep your eye on that area. a big buck might just be walking in your area.
