Your article featured on the front page of the Research section1 seems to have a picture of the grizzly bear and not the black bear. I have shooed enough black bears off my front porch to know the difference. New York has a sizable black bear population, and now and again one or two wander into town. Grizzly bears are more common west of the Mississippi. There is a hump at the shoulder to define them. [The bear in] your picture has a hump.
Recently, if you check the New York Times, we had a black bear in Queens, living in a dumpster of an Italian restaurant. I don't know how this affected his or her bone density, but the critter did become rather obese on the rich food.
