It was a wild Monday in the suburbs west of Boston, with reports of a black bear ambling down by the Charles River in Needham and sightings of a 600-pound moose racing through backyards and across streets in Wellesley.

“Unbelievable! He got up on his hinds, he was big,” said Needham resident Walter Hasenfus, who spotted the bear in the woods behind the Charles River Landing luxury apartments on Second Avenue. “He was right on the edge of the banks. He was just moseying along, didn’t have a care in the world.”
