When the babies are born, it's called a litter. A mother can have a litter of one to four baby bears. Baby bears are called cubs. Cubs are born in caves or dens. A den is a bear's home.
Bears remain with their mother at least through their first year.
They become mature at 2 to 5 years of age and live 15 to 30 years in the wild. Bears truly are magnificent animals. They are wonderful to watch, but we need to remember that they are also wild animals that demand our respect. They are strong and agile, they will defend themselves, their young and their territory if they feel threatened.
