Bear & Two Cubs Stuck In A Tree In Altadena, Calif. (VIDEO)

A mama bear and her two cubs have been sleeping and hanging out in a tree above a neighborhood near Altadena, Calif. Thursday, and they show no signs of tiring of their new home.

Kinneloa Mesa homeowners first spotted the bears in their driveway early Thursday morning, reports Altadena Patch, and by 9:30 a.m. the black bear trio had climbed up into a nearby tree. They have been napping and relaxing there ever since.

"They're waking up from their winter hibernation," explained a Fish and Game representative to CBS2. "We had a warm spell, I believe, about a week ago, and that really brought them out."

The bears won't be brought down by tranquilizer darts or other means, reports CBS2, because they aren't perceived as a threat to the community. Instead, officials are waiting to see if the bears will come down on their own and leave the area.

Eventually, Fish and Game officers closed the area off to onlookers in order to keep the mother bear calm, reports the Los Angeles Times. Referencing the noise from news helicopters, Fish and Game spokesperson Andrew Hughan told the Times that, "the only way to help these bears right now is to back off."

In early April, Fish and Game officials responded to reports of a bear in Glendale who was roaming around backyards and rummaging through trash cans. They were able to tranquilize the bear with two darts and return him to the wild, but not before the bear scared the living daylights out of a man who was texting as he walked to his garage. KTLA captured the almost-collision.
