No, black bears typically do not eat red foxes. While black bears are omnivorous and have a diverse diet, their primary sources of food include fruits, nuts, insects, and small mammals. Red foxes, being more agile and quicker than a bear, are not a common prey for them.
Black bears might scavenge on carrion or take advantage of an easy meal if the opportunity arises, but they do not actively hunt red foxes. Additionally, red foxes have developed various means to avoid predators, including bears. They tend to stay in wooded areas where they can quickly escape if threatened.
In summary, while black bears might eat small mammals occasionally, red foxes are generally safe from being a meal for them.
