Black bears have good eye sight, which is similar to that of humans. And they can identify unnatural patterns and colors. That means you need to use the right camouflage during Canada bear hunts. If there are coniferous trees in the area, then your camouflage must include pine bark and pine needles. Black bear hunting outfitters can help you decide what type of camouflage you need to use for your hunting trip.
Aside from using the right camouflage, you also need to master being motionless. Even if you are wearing the right camouflage, you can still startle the black bear if you keep on moving.
Although a bears eyesight isn't good, they can still identify unnatural patterns & colors.
