This article represents my simple and crude interpretation of Dave Smith's insights on outdoor bear encounters based on some of the available literature. If the reader is unfortunate enough to encounter a bear in any way that does not concern me, please interpret with caution, read the book, and refer to the relevant literature, etc.
In the outdoors, bears rarely attack teams of four or more, and never attack teams of six or more.
Bears never attack teams of two or more people who are standing still or holding their ground.
Bears can be frightened when people suddenly enter their range. A frightened bear will run or fight. Most bears that live in the forest have evolved to hide or run away. A very small percentage will choose to fight in order to protect themselves or their babies and will come at you. A very few curious bears may also rush towards you to try to figure out the nature of your situation. At this point your reaction determines their behavior. If you choose to run away out of fear, this is a clear sign of weakness and will trigger their pursuit response, which is much faster than a human; you may choose to climb a tree, which it also climbs faster than you, and it will drag you down from the tree. The safest and probably most counter-intuitive response is to stand still and not make any kinds of unexpected movements or moves to show it that you are not a threat to it, but also to show that you are not easily tamed and will not be easily knocked down, and that if it attacks you, it will pay the price. Keep an eye on its every move, maintain eye contact and don't take your eyes off it. A bear that comes at you will generally stop at a closer distance. When it confirms that you are not a threat, it will slowly move away. If it never leaves, perhaps because you are between it and its food or in its forward path, you can try backing up slowly to 45 degrees back. If it reacts in an irritable manner, such as panting rapidly and making sounds like teeth clacking, stop backing up immediately.
If it doesn't stop but continues to approach and attack, start playing dead after it attacks. Playing dead is a way to show a frightened bear that you are not a threat, and soon it will stop attacking. Key points of playing dead: The bear will mainly attack the opponent's head, so immediately lie face down on the ground with your arms crossed behind your head, your elbows close together to protect your brain, and your legs slightly apart to prevent it from flipping you over. Don't start playing dead before it touches you, it's like telling it, "I'm too weak, I'm giving up resistance, I'm yours, you're on your own. This will allow the bear, which was still fearful, to start attacking recklessly and actively.
If the attack lasts more than a minute, it may not voluntarily stop attacking. This is the time to take the initiative and counterattack. Attack it in every possible way. Your life depends on your counterattack.
If the bear stops attacking and then slowly leaves, do not sit or stand up immediately, but wait until it is far away before getting up. If it is not far enough away to sit up, it will likely trigger a second attack, which will be stronger and do more damage.
If you find a bear around your tent in the middle of the night, or if it has entered the tent, you can yell and make every possible sound to drive it away. You can have a few rocks in the vestibule of the tent and throwing them at it may be effective. Do not throw too big a stone, as it may kill it if it hits its head. You can suddenly shine a bright flashlight into its eyes to temporarily blind it. You can also spray its eyes with pepper spray. If it has already found and started to enjoy your food, you'd better leave quietly, if you disturb it to eat at this time, it may be bitten. Wait until it has finished its food before you can go back to clean up the mess.
On extremely rare occasions, a bear will go into hunting mode. It will approach its prey (human) quietly, ears forward, head up, feet on the ground, attention completely focused on you, approaching you confidently, or circling around you and getting closer. Then the attack begins. Never play dead when encountering a bear in hunting mode, but fight back directly. A bear that enters hunt mode while in camp will drag the bitten person away from the tent and begin ...... At this point the injured person still has hope of being saved. The bear will first gnaw on the softer parts of the human body, such as the internal organs, and the injured person is still alive within an hour. Quickly gather your teammates together to blast them away and rescue the injured person. Never trap a bear in the middle.
May wilderness walkers live in harmony with bears.
