Cú Lừa Dưới Tuyết Cách Chuột Đồng Bẻ Cong Âm Thanh Để Thoát Khỏi Cáo Đỏ và Chim Cú

The hungry red fox crawled deep inside the carcass of a wild ox. The frozen corpse was as rigid as stone in the extreme cold of minus 40 degrees Celsius. In the bitter winter of Z, every bite of food was a lifebuoy for it. It had to eat very quickly, because seven hungry fox cubs were waiting in line. Still waiting for it to return from hunting, but fed only on the nutrients from a few残缺 bones. The mother fox's milk supply was barely enough to feed so many little ones at once. With seven tiny souls barely clinging to life, it had no choice but to plunge into the snowstorm once more. The howling blizzard Z made everything seem exhausted, yet the neighbor was only half a meter away. I'm hiding again in the cozy snow cave, enjoying a fairly comfortable life. A thick layer of snow, combined with perfect insulation, kept the bone-chilling cold outside. There is no lack of stored food here, nor is there a shortage of friends to play with. As for the snowflakes, they can calmly pass through winter here. But an invisible threat constantly keeps this species of field mouse in a state of fear. The hearing of the North American red fox is extremely sensitive; it can detect even the faintest sounds beneath thick snow. However, the field mouse is no ordinary creature. As soon as the snowstorm stops blowing, it will minimize noise as much as possible during operation. But this little trick, the red fox seemed to have a way of dealing with it by tilting its head back and forth. It absorbed the slightest movements from below, using both hands as reference points. It continuously adjusts the precise position of the prey. This method is identical to the triangulation technique used in geodesy. The old man moves left and right to compare the differences between the two hands. It can securely lock the target's position. The error is usually no more than 5 cm. After completing the wind search, the red fox demonstrated an astonishing leaping ability. It descended from above like a precisely guided missile. But the red accusation was unexpected. Field mice actually possess a perfect missile defense system. Their ability to survive for long periods under snow depends on much more than just luck. Field mice dig tunnels to search for fresh vegetation. While searching for food, they continuously emit ultrasonic waves to inform their companions of the red fox's location. They emit ultrasonic waves at a frequency of 20 kHz, a sound that even red foxes cannot hear. Through these encrypted intelligence reports, the field mouse can share the predator's location in real time. If we install a few more highly sensitive microphones, we'll be able to read this secret message. The red fox's triangular vision, though somewhat advanced, still struggles to judge depth and extremely short distances. The field mouse can always successfully escape. Just before the enemy launched their attack. The cattle stop kindly when plowing through the snow to find dry grass, sometimes inadvertently exposing the field mice's tracks to the red fox. But living in the same area, this is no different from a deadly mockery. During the nursing stage, red foxes need to eat at least 15 mice per day. Only when it ensures enough food for itself can it feed its seven little ones. Although the red fox cannot crack the secret information, the field mouse should not rejoice too soon either. To fill that belly, they always find effective scent-tracking methods. The red fox possesses a biological electronic warfare system. The position where it is standing is very close to the Earth's magnetic north pole. And the light-sensitive protein in the fox's retina can perfectly perceive the inclination of the magnetic field. At this moment, simply orient your body toward the northeast. Create an angle of 20 degrees from the magnetic north. It can transform a clumsy, groping attack into a precise and deadly strike. Combining magnetic field-based localization and navigation, its success rate can reach up to 74%, despite the mouse's small size. But compared to the dull, lifeless taste of dry grass, this fresh meat flavor is clearly in a different league. However, if it deviates even slightly from this 20-degree angle, the success rate will drop to just 18%. If one says the red fox won thanks to advanced biotechnology, then the character below relies entirely on hacker instinct. This little boy with big round eyes is named Linh Du. It's the very same admin rat we often see, those survival skills of the field mouse. To it, it's no different from trash. Linh Du often shivers due to cold. That tingling sensation is also insufficient to generate enough heat for the body. When the body can no longer endure, it always wants to find a hole to crawl into. The field mouse's burrow is as if specially designed for it. The narrow tunnel system retains about 90% of the air. This static air volume acts as a natural insulating layer, Help it not worry about heat loss. As we all know, this creature's visit to the house is clearly not just a passing one. The complex and extensive network of tunnels, although it may help the field mouse temporarily escape pursuit, Yet, the lingering scent of their bodies became an inescapable, fatal weakness. The flexible body of the spirit companion can freely weave through the labyrinthine tunnels. Following the faint scent of the mouse, it traced every trace left by the field mouse. This unyielding scent leaves the field mice nowhere to hide. For the red fish, the field mouse is just a light appetizer. But for the ascetic, it is a meal for the entire day. The weasel not only kills the field mouse but even takes over its burrow. After eating its fill, the spirit creature will pluck the fur off the field mouse. To decorate their new home here, It can comfortably avoid the cold outdoors. As for the half-eaten mouse waste, there's no worry about rotting or emitting odors due to the low temperature. However, if it truly considers itself the owner of the red fish, It's very likely that it will be caught red-handed, like a mouse. After the dual attack from both the red fox and the weasel, This house can no longer be lived in. Perhaps moving house is the mouse's only option right now. For small and weak animal species, There is no place that is truly safe. To survive, it had to lead itself into danger. Outside, it appears calm and peaceful, but in reality, it conceals an invisible killer, even more ferocious in its scent. The field mouse hadn't even had a chance to clearly see the other party's face. was mercilessly knocked down into the Snow Temple. The great horned owl, also known as the tiger owl, is the largest owl species in the world by body size. Its head can rotate up to 270 degrees. The enormous flat disc functions as a radar antenna. It has the effect of converging and dispersing low-frequency sounds. Around the face is a ring of stiff brown hairs arranged in a circle, acting as an acoustic reflector Can penetrate through a thick layer of snow 60 cm deep. The tiny creature seemed to be completely surrounded. All pathways from underground to above ground are sealed off. in desperation It only has the option of digging tunnels to reach more distant areas. Try using distance and depth to avoid the relentless pursuit by the enemy. But even if they ran as far as 50 meters away, beneath the half-meter-thick layer of snow It still could not escape the keen perception of the great savior. The field mouse clearly understood that As long as I keep absolute silence, The round-faced one above won't be able to do anything. But it seems it had underestimated the momentum of the repentance. From a distance of dozens of meters, It could be due to accurately detecting the faint heartbeat of the mouse. The round wrinkles on the face This arrhythmia will increase by more than 10 times. Because the metabolic process in rats occurs very rapidly. It must continuously search for food to sustain life. And precisely that sound made while foraging for food had kept it constantly within the surveillance of the lurking hunter. As soon as he detected the sound beneath the snow, Cú Sám will shake his head back and forth. Through asymmetrical hands to capture sound waves only 30 micrometers long After comparing audio latency, Usually no more than a single step. The feather fringe on the owl's wing edge is structured like tiny combs. Let it soar like a ghost, It produces no sound whatsoever, even at high speed. Yet, this cycle of rebirth still ended in failure. Field mice facing different opponents will reveal distinctive defensive capabilities Despite the fierce assault, there was not the slightest opening. But in the end, there was still a small mistake. It turned out that the layer of snow did not only muffle the sounds and also causes the phenomenon of mottling. It seems that field mice are active in this location. but the actual position where the sám so could be It can be farther than it sounds. The only way to break through this situation it must be approached closer to the sound source. This silent, stealthy flying style making the field mouse completely unaware of anything. As Cú Sám drew closer, The distortion of the sound gradually decreases. When it hung right above the sound source, All disturbances are eliminated. Compared to the sound of a field mouse, The greater the roar when hunting prey successfully during a time of scarce food. Sometimes just for one full meal, They are also ready to fight each other violently. A large barn owl must eat nearly 2,000 field mice each year, On average, about 5.4 offspring per day. This not only helps us supplement nutrients just curbed the surge of the rat problem. There is only one complete food chain. can only maintain the balance of the ecosystem.
