Result is better than a wounded bird hunter. The incident was properly reported to wildlife officials. Hopefully, they responded properly by having a professional hunter more appropriately armed go after the wounded bear soon after the incident. If the bear can't be found pretty quickly, it probably wasn't that injured but has a renewed respect for the capabilities of human beings after being frightened or wounded enough to break off its attack.
The bird hunter may have been using heavy-shot instead of lead shot if he was shooting bigger birds like chickens or pheasants. Heavy- shot is just that, heavier than lead and more deadly because of increased penetration due to extra weight of the projectiles.
