I have spotted and stalked black bears before; and for me its about wind and walking quietly over anything.
Here in Idaho in the spring; the wet ground seems like an easy way to go; but the grinding of rocks underground together has not been a friend.
If you can find existing trails; and slowly stick on the trails your odds go up.
Bear trails are the best to follow; as they really like to be quiet and will remove twigs and noisy stuff as they walk the trail.
Elk and deer trails can be good - but all game trails have obstacles- like stuff they either push through or go under.
I really like windy days - although wind can swirl; when there are regular puffs of strong wind; you can use these moments to move through bit by bit- really noisy stuff: undetected.
I carry and use binoculars when I do this; I carry mine inside my jacket under my right arm; you need to use a longer than ussual strap to do so- I use a boot lace.
I do this because you don't need your binoculars to drag or catch on something while your sneaking through stuff.
I move a short distance; glass; and move a short distance again; the shorter the distance often is to the advantage.
When I glass I look for anything that might be a part of a bear; but mostly I look for brush moving.
When a bear is bedded; you just about have to trip over it to find it. But when they feed; you can see bushes moving as they strip off berries etc.
In the fall the wasps move from paper nests to ground nests. The wasps move their larvae to the ground nests; and bears love the larvae.
When they are digging them up you can hear it; but more often you can hear them grumbling about the stings they are recieving.
As wasps like using old road beds; and old road beds can be the quietiest place to stalk; watching for the paper nests in trees; and then really scoping the trails and areas near them- you can do some super snooping.
I have heard that bears are not totally color blind. That makes some sense as they come in different colors; but I have heard they can see blue over other colors.
I had a bait this year with a stand over it; and a friend sat in it with blue jeans on; and the bears figured the stand location out where they had not before. It may have been movement - but bluejeans just don't seem appropriate.
I camo up as good as I can; including face paint.
Watch for any movement out of place ( if you look at a spot when the wind is blowing- then keep watching as the wind slows you will spot movement that is out of place).
Keep in mind the better you do this; the higher the chance of success - but too: the higher the chance you will get close to sows and cubs.
Its fun stuff.
I would like to say I have killed several bears this way- but I don't remember killing any this way. I have been succesful at getting close enough to touch bears with my bow; but I always had already filled my tag; or the bear was on someones bait; or was not the bear I wanted to take.
But I have 'counted coup' on several; reaching out slowly and tapping them with my bow. The bears have always taken off quickly; and a couple have come back and popped their jaws in anger; but so far; I haven't gotten beaten up for it.
I had a relative that used to shoot deer with a rifle for lumber camps; and he told me that each step in the woods reveals a completely different woods- that is that each step lets you see something new.
I do that when I am stalking; and it is good advise for any game.
Fun stuff!!! good luck
