Schools in Arlington are being delayed this morning by an hour after a bear made several appearances in the Boston suburb.

The bear was first spotted in the area in the area of Scituate Street at Spring, according to Arlington police.

Officers responded and in a short time updated that the wandering bruin and then been spotted in the area of Paul Revere Road and Park Avenue.

Arlington Police, along with the town’s animal control officer and the Massachusetts Environmental police have responded.

Officers are also monitoring in the area of the town’s schools.

Monday’s sighting comes after a bear caused a stir in Newton on Sunday. It’s not know at this time if the Arlington and Newton ursids are the same animal.

Newton police on Sunday shared video of a black bear in that community after it made an appearance in Newton Highlands near Cold Springs Park.

Environmental police, in a statement to the Herald on Sunday, said that no aggressive behavior had been observed related to the Newton sighting.

“If a bear is seen in town, leave the animal alone and keep pets leashed,” a spokesperson for the  Environmental Police said in the statemeent. “A gathering of people not only stresses the animal, but adds the risk of having a bear chased out into traffic or into a group of bystanders. In most situations, if left alone, bears will return to forested areas on their own.”

With the black bear population’s range expanding east toward the most densely populated Bay State communities, bear sightings are increasing — especially during these peak months for bear activity.

May, June, and July are peak months for bear activity and reported conflicts with bears in Massachusetts. This is because 1-year-old cubs are leaving their mothers for the first time, and are finding new territories. June is also the peak of the bear mating season, leading to lots of activity and movement tied to mating.

Arlington police have requested any bear sightings in that community be reported immediately,  to police dispatch at 781-643-1212.
