* Mother's milk: This is their primary source of nutrition in the early months of life.
* Foods brought back to the den by the mother: As cubs get older, their mother will start bringing back food to the den, like:
* Berries
* Insects
* Small animals (like rodents or young birds)
* Honey
As cubs get older (around 18 months), they'll start venturing out with their mother to learn how to find food on their own. They'll gradually transition to eating a more varied diet of plants, berries, nuts, insects, and small animals.
It's important to note that cub black bears are completely dependent on their mothers for survival, and they learn everything they need to know about foraging and survival from them.
