except is NOT bears don't like getting there pictures taken,m well on why your trail camera's have gotten damaged
as you already pointed out a bear has an incredible sense of smell, and most times they SMELL the camera's , most times its due to HUMANS having handled the camera's and had some sort of scent transfered from hands to camera's that smell like food or ?? and makes a bear curious, add in most camera's make noise when taking pic;s
and you now have a animal that is extremely curious by nature
and tends to find out many times what they like to eat by tasting things, which is also why many cam's get chewed on
there first attracted to smell, then sound and then BITE to see what it tastes like!
not about being shy LOL
wearing rubber gloves before handling a camera that has been sprayed down to remove scents will help prevent trail cam's from betting bear damaged
Started running trail cam's in the 90's(35mm film one's)
have NOT had one damaged by a bear since I switched to using rubber gloves to handle them, (or metal bear boxes) in about 15+ yrs now!
and am running cam's in extremely high bear density areas!
