Black bears are the most common and widespread bear in North America. Adults average 150 to 400 pounds, with mature boars in food-rich regions occasionally pushing past 600. Despite the name, color phase is highly variable — true black is most common east of the Mississippi, but cinnamon, chocolate, blonde, and even white (Kermode) and blue-gray (glacier) phases show up in the West and the Pacific Northwest. Color does not predict size or sex; agencies and houndsmen learn to read body shape and head profile to age a bear on the hoof.
They are omnivores driven by calories. Spring diets lean on emerging grasses, forbs, and winter-kill carrion. Summer shifts to berries, insects, and small mammals. Fall is hyperphagia — bears can put down 20,000 calories a day chasing acorns, beechnuts, salmon, or whatever the local mast crop offers. That fall feeding window is what most hunting seasons are built around.
Black bears den in winter across most of their range. Sows give birth to one to four cubs in the den, typically in alternating years. The species has rebounded across the Lower 48 over the past four decades — populations are now expanding into states like Missouri, Nevada, and Texas where they were functionally gone a century ago.
