As another FReeper pointed out, this was discussed on a thread yesterday.
The man lives in a suburb of Worchester, MA. The town of Auburn has a population of 15K. It is probably 40 miles west of downtown Boston. This is not out in the country. He almost certainly has other houses within 500’ of his.
He went out to fill his bird feeder. There was a bear in his back yard. It chased him. He went out a second time to fill the feeder. This time he was armed with his shotgun. He shot and killed the bear.
Black bears bluff charge all the time. It’s what they do. This bear most likely had been habituated to food set out by careless homeowners who need to make up their minds if they want to live in a rural area or a manicured suburb, and then adjust their behavior accordingly. Any homeowner who knows there are bears prowling about and persists in setting out food is reckless — endangering himself, others, and inevitably the bear. A fed bear is a dead bear.
If this homeowner lives in an incorporated town with other residences close by, it is reckless and possibly unlawful to be discharging a firearm unless his life is threatened. Being pestered by a bear lured onto your property because you baited your backyard is not a threat to life. It’s an inconvenience. I think the guy’s a jerk.
Finally: in bear country there are frequently laws against setting out food or trash that will attract bears to populated areas. Just saying.
