Another black bear sighting in north Waltham

A home security camera captured a bear walking through a residential area off Trapelo Road on the night of March 31.

Similar sightings have been reported across the city in recent weeks, including footage of a bear approaching a home and investigating items on a porch. 

City officials have acknowledged reports of the bear in the area. Wildlife experts say black bears are becoming more common in eastern Massachusetts and often enter neighborhoods while searching for food sources such as trash, bird feeders or pet food. 

Residents are advised to secure garbage, remove food attractants and keep a safe distance if a bear is seen.
