A New Jersey black bear that walks upright on its two back legs and has become a social media darling has re-emerged and has been captured on video months after its last sighting. The bear named Pedals was spotted in the town of Oak Ridge. In a video posted to Facebook featuring the bear, it appeared to be in relatively good health and was moving quickly. (1) Pedals apparently has an injured leg or paw that doesn’t allow it to walk comfortably on all fours according to experts. Lawrence Hajna, spokesman for the state Department of Environmental Protection, said officials expect the bear to make it through next winter. (2) The bear first gained fame after it was spotted wandering around neighborhoods and was caught on videos that were posted on social media and shown on national television. Last year, supporters pushed for Pedals to be moved to a shelter, but New Jersey officials have said they won’t allow the bear to be captured and transferred to the facility. "The bear would do better in its natural habitat and the agency would step in if its condition deteriorated," they said.
