A recent post said:

a black bear can kill a man (or a dog) with a single swat of its paw.

I suppose anything is possible. But is it realistic? Has it ever happened?

Googling 'man killed by single punch' finds several instance where a person killed a person with one punch. I also find a lion killed a person with a single swipe. But not finding anything about a black bear doing this.

Are there any records of this happening?

    Too broad. Also subject to interpretation. It is same like asking if a person can be killed by a bike accident. There are too many variables involved. How strong was the swat? How old was the bear? How old was the person? Etc... – Ricketyship Mar 06 '18 at 11:41

    How is "Has a black bear killed a man with single swat?" too broad? It is either yes or no evidence found. Obviously you can not prove a negative. If it has occurred there should be some evidence. – James Jenkins Mar 06 '18 at 12:05
  • "Can a black bear kill a man with a single swat" is different from "Has a black bear ever killed a man with a single swat". The title of your question has "Can a black bear kill a man with single swat". – Ricketyship Mar 06 '18 at 12:08

    Even if the question were "Has a black bear ever killed a man with a single swat?", I do not see how this could add value. IMO a single yes/no answer would probably have no more significance than providing a factual check. – Ricketyship Mar 06 '18 at 12:13

    @Ricketyship I fail to see the difference between the two since if it has ever happened then it means it’s possible and if not we simply don’t have enough evidence – Charlie Brumbaugh Mar 06 '18 at 14:38

    If a human and a lion can both kill with a single swat, why would you think a bear couldn't? There is likely nothing when searched because they may not stop after one swipe and may or may not nibble on the body. But a bear is much stronger than a man or a lion and has very large paws and claws that could easily break a neck or cut a throat with a good swipe. – Nate W Mar 06 '18 at 17:24

    @CharlieBrumbaugh Something that's (provably) theoretically possible might not ever have happened before (or there might not be proof of it having happened). Showing that it can happen by determining the strength of a bear's swat wouldn't tell you whether it has happened. – NotThatGuy Mar 06 '18 at 20:08

    This seems like potentially a better fit for [skeptics.se] (not that I'm active on either site). – NotThatGuy Mar 06 '18 at 20:12

    Skeptics wouldn't accept it without a notable claim, but as it stands it is not answerable here. The title can obviously be answered yes, the body question is just a research piece. – Rory Alsop Mar 06 '18 at 23:08

    I disagree that this is subjective or opinion based. It takes a knowledge of physiology (human) and bear strenght, but in principle an informed answer (or at least an informed estimate) can be given, as the two answers show. There is far too much knee-jerk "opinion based" criticism on this site, and this is often code for "I don't know, therefore, nobody knows." Presumptious! – ab2 Jul 22 '22 at 20:10

I am going to say yes, it is possible mostly because humans kill other humans with a single punch from time to time and black bears are certainly stronger.

Cupido said there are “hundreds” of documented one-punch deaths nationwide.

One-punch deaths fall even further down the list. But it happens often enough that Gunson, without pause, is able to describe precisely how a sock to the face can end a life.

“They fall over backwards and they hit the back of their head,” Gunson said. “They often end up having a skull fracture.”

Source

However, I can find no record of it happening in Wikipedias list of fatal bear attacks in North America. From the research that I did for this answer, it seems that most bear attacks are a lot messier than a single punch kill.

On the other hand people have survived punching bears.

A Canadian man had to punch a black bear in the nose to force it outside after it followed a toddler into a British Columbia family's home.

Source

Nelson tried to swing at the bear but missed, hitting it in the teeth. The bear hit back, scratching Nelson across the chest and face.

"I knew it would swing first with its left but it would really come with its right, because most bears are right-handed," Nelson said.

So Nelson swung a second time.

'Most bears are right-handed.'

"I had the perfect shot to take. I did an underhand and hit it right in the snout."

Depends on the size of the bear.

Black bears vary in size, small female bears can weigh in under 100 lbs, which makes them about the same size as a large dog. But big black bears can weigh in at more than 600 lbs. The largest black bear on record was in New Brunswick in Canada, and is estimated to have weighed ~1,100 lbs!

A swat to the head by a bear of sufficient mass will undoubtedly be enough to end your life, as sure as a baseball bat to the head can kill you. Keep in mind that a seemingly innocuous hit to the head can be fatal to humans.

The strike force of a bear should not be underestimated. Grizzly bears for example have allegedly been recorded on multiple occasions—although occurrences are still very rare—decapitating moose with one swipe to the head (moose have since been discovered to have a peculiar weakness in their necks that make them prone to decapitation, but still). A large Black Bear is about the same size as an average Grizzly, so it's not unreasonable to assume a big enough black bear could potentially take your head off if it landed a well placed swat your cranium, although you'd more than likely be sent flying with your head still attached.
