In July, male black bears, known
as boars, scent mark their territory in the Great Smoky
they do by
rubbing and scratching their scent glands against trees.
This communication is an invitation to female bears in search
a mate. Female bears are called sows, and begin searching
for mates at three to five years old. Once in heat, they
mate with more than one partner for a period of two to three
weeks. Each of her male companions will do the same.
The older female Black Bear comes into
heat only after her cubs are old enough to be out on their
own. Once mating reoccurs, her fertilized eggs do not implant
themselves in her womb until late fall as hibernation season
nears. This process of fertilization and implantation is called
delayed implantation. After delayed implantation, the embryos
attach themselves to the mother bears womb and development
continues through much of her hibernation period. Two hundred
twenty days after conception the bear cubs are born while
the mother is still hibernating.
