Do Wounded Bears Attack More? Handgun Defense Data Tells a Different Story

One theory about defending against bear attacks is this: Defenders must be careful not to shoot a bear without immediately killing it, because wounded bears are more likely to attack. The theory has been put forward for many decades. One of those who put the theory up for consideration was Stephen Herrero in his book, “Bear Attacks: Their Causes and Avoidance“. On page 241 of the 1985 edition, Herrero writes:

Of course, if an aggressive bear actually attacks you or a companion, a firearm may be a lifesaver, or it may cause a wounded bear to intensify its attack. 

Herrero puts forward the theory. He does not appear to have data to determine how common such reactions may be. His speculation has been shared by numerous others.

With over 200 documented incidents where a handgun was fired in defense against bears, this correspondent has numbers that indicate 21% of bears continue to attack after they are shot.

Of 175 incidents in which bears were shot, bears stopped attacking in 138 cases and persisted in 37 cases. Warning shots were effective in 23 of 44 cases. In 8 of the 23 cases, the positive effect of the warning shot(s) was temporary. In four cases, it could not be determined whether the bears were wounded or whether the shots were effective. Of the 175 incidents where bears were shot, 29 were shot after a person was already injured by the bear. Of the 146 incidents where the bear was shot before a person was injured, the bears persisted after being shot in 31 cases, also 21%.

If you shoot a bear, 4 out of 5 times the bear will be killed or will leave the area.

Animals do not like being hurt any more than humans do.

What an amazing discover.

I think a distinction should probably be made between the Grizzly and the Black Bear. I didn’t see any in these paragraphs. The distinction with a Grizzly there probably isn’t much choice anyway.

I suspect many of the bears that keep fighting when wounded are mama bears with cubs. They still might need to be shot, and bear spray may be less effective on them, but the situation is still much sadder. I would appreciate seeing an analysis distinguishing bear defense against sow bears with cubs. Are they more or less likely to be deterred with a warning shot? Are their attacks more or less lethal on people? Is bear spray more or less effective? Are they more or less likely to keep attacking when they are wounded?

freind shot and wounded a bear- the bear ran into a thicket- he waited awhile, then tracked it and before he could enter the thicket- it charged out at him and slammed into him, knocked him over- He was able to take another shot- which finished it- just another day hunting in the wilds of the midwest

Should have been:

Most bears stop attacking when shot or they are killed.
