The biggest sensation on Cape Cod right now isn't the lobster, the historic lighthouses or its rolling sand dunes. It's not even a Kennedy. It's a bear. A bruin believed to have swum about 500 feet (152 meters) across the Cape Cod Canal from the Massachusetts mainland in late May has captured the imagination of residents as it traipses across the peninsula. Officials say research dating to the 1700s suggests this is the first bear on the Cape. Boston-area newscasts are featuring daily updates on the bear's whereabouts, and a Cape Cod Bear Twitter feed has nearly 1,300 followers. A local brewery is even offering bear-themed shirts. “Well, my goodness. How often do you see a bear on Cape Cod?” said Marion Larson, a spokeswoman for the Massachusetts Division of Fisheries and Wildlife. “It's really cool and people are really excited about it.” A Cape Cod Times reporter told the paper she spotted the bear around 6 a.m. Thursday and said it bounded across the road like a puppy. The bear, likely a male about 3 years old weighing 150 to 200 pounds (68 to 90 kilograms), has been seen near a chicken coop, a cranberry bog, a golf course and more than a dozen other locations along a 60-mile (96-kilometer) stretch of the Cape from Sandwich east to Provincetown. Now that the bear has reached the tip of the Cape, wildlife officials say they may attempt to immobilize and move it to an area where other bears live. Officials say it's possible the bear could retrace its steps and head west, but they are looking for a chance to possibly relocate it now that it's reached the end of the Cape. “He's at the end of the line, as far as real estate,” Larson said. The bear can only be tranquilized if officials can isolate it in a tree or some other confined space, said Laura Conlee, the state's bear expert. Another option would be to try to catch it in a trap that basically consists of two 55-gallon (208-liter) steel drums welded together and then move it elsewhere. But Provincetown police Officer Ruth Anne Cowing, who handles animal control duties for the town, said officials there are hoping the bear will retrace its steps and get out of town. So far it's stayed mostly in the woods and retreated every time it's seen a person. “Now he's at the very end so he needs to make a decision or we'll make it for him,” she said. “We think he's here looking for a mate ... We're hoping he realizes he's the only one here, and he turns around and goes back home.” Cowing usually handles calls about dogs, foxes and raccoons. She's already had four reports this week of bear sightings, two on Wednesday and two more on Thursday. “We're all really excited about the bear,” she said. “It's so unusual to have that species down here.” The running joke in Provincetown, a gay vacation destination, is that the animal should stick around for a July event dedicated to men known as bears, who embrace natural body hair. “The big joke is he's six weeks early for bear week in Provincetown,” Cowing said.
