Can fly over Mount Everest in one go, why can bar headed geese be afraid of altitude sickness?

In nature, there are many animals with seasonal migration habits, and this habit is even more common among birds. Migration is never easy for birds or other animals with seasonal migration habits, and in the process of migration, wild animals have to go through hardships and dangers before they can finally reach their destination, and as the seasons change, they have to return the same way, so that the biannual migration has been going on again and again. Among the migratory birds, there is a bird that has a difficult migration path because it has to pass through the Qinghai-Tibet Plateau and climb over the Himalayas with an average altitude of more than 7,000 meters.

The Bar-headed Goose is a recognizable bird, and its main feature is the two parallel markings on its head. Bar-headed geese are a widely distributed bird, in China's Qinghai Lake and Mongolia are distributed, and these bar-headed geese distributed in the northern region will embark on a long migration journey in autumn, they will fly all the way south, through the Qinghai-Tibet Plateau, then over the Himalayas, and finally inhabit the warm and humid lake areas of southern India, and in the following spring, they will return to their home in the north. The whole migration journey of the bar-headed goose is more than 3,000 kilometers long, generally speaking, the time it takes for the bar-headed goose to go south is longer, nearly 3 months, and the return time is shorter, only about one and a half months to complete the journey.

For a long time, biologists have been puzzled by the migratory behavior of the bar-headed goose, because crossing the Himalayas in one go is no easy task, let alone any bird.

Researchers have found that there are two distinct metabolic patterns in the body of the bar-headed goose, when it is in the plains, the bar-headed goose uses a normal metabolic mode, and once it enters the high altitude area, the bar-headed goose will turn on the energy-saving mode to cope with the lack of oxygen and the decrease in air pressure. This energy-saving mode simply stops all unnecessary consumption. To reduce all unnecessary exertion, bar-headed geese will shrink their intestines even before migrating, reducing the amount of energy needed for digestion.

After turning off all unnecessary consumption, the metabolic rate of the bar-headed goose decreases, and the decrease in metabolic rate directly produces two amazing effects, the first is that the heart rate remains the same all the time. Most animals, including humans, have an increased heart rate when they lack oxygen, in order to deliver oxygen to the body faster, but the heart rate of the bar-headed goose does not change. The second is the drop in body temperature, human body temperature will rise when exercising, and bar-headed goose will not rise, but fall, after the body temperature decreases, the ability of hemoglobin to bind oxygen will increase, thus making up for the lack of oxygen caused by the lack of oxygen environment.

It is by relying on the metabolic mode that can be switched at will that the bar-headed goose can complete its migration journey in one go. Researchers have concluded that, judging from the physical functions of the bar-headed geese, they can not only fly over the Himalayas, but also over Mount Everest.

The main reason for this is because the animal has two sets of metabolic systems, when the pressure rises, its metabolism will switch to another mode, the body's metabolism becomes very slow, and even the heartbeat begins to change, which is the main reason why it can fly over Mount Everest without fear of altitude sickness.

Because this bird's body structure can cope with these harsh weather, it can cope with altitude sickness.

Because there are two distinct metabolic modes in the body of the bar-headed goose, when it is in the plains, the bar-headed goose uses the normal metabolic mode, and once it enters the high altitude area, the bar-headed goose will turn on the energy-saving mode to cope with the lack of oxygen and the decrease in air pressure. This energy-saving mode simply stops all unnecessary consumption.

Because the lungs of the bar-headed goose are very well developed. Because the bar-headed goose will take a big breath before entering Mount Everest, and will regulate the breathing state of its lungs, it can withstand the high pressure of Mount Everest and can fly over Mount Everest.

This is because this creature has a very strong ability to fly, has very strong endurance, and has a very tenacious vitality, so it can fly over Mount Everest in one go. It does so thanks to its unique body structure.

Because this bird is able to fly at an altitude of 9,000 meters, it is very hardy, it has large wings and strong muscles, so it is able to do this.

Because the bar-headed goose will shrink its stomach and intestines during the migration process, reducing the energy consumption during the flight, it can fly over Mount Everest in one go.

Because the bar-headed goose is a bird that can adapt well to highland life.

Because the bar-headed goose is originally a bird that lives on the plateau, it can adapt to the living environment where oxygen is scarce.

Because he often lives in highland areas, he is perfectly adapted to this height.

Because the bar-headed goose has two sets of metabolic systems in its body, it can switch between low and high altitudes at will, and it can also judge the shortest flight distance.

Bar-headed goose is an outstanding high-altitude flying master in the flock, every year it has to fly to the south to give birth to young birds, Mount Everest is high altitude and low air pressure, and general birds are unable to fly, which is what makes it different.

Because in the process of flying over Mount Everest, the altitude is appropriately lowered, and it also moves forward against the wind, unlike other birds, the bar-headed goose is able to shrink the intestines, thereby reducing the energy needed for digestion to cope with the lack of oxygen and the decrease in air pressure.

Because the physiological structure of the bar-headed goose can adapt to the cold and oxygen-deficient environment at high altitude, it can fly over Mount Everest without altitude sickness.

Because the heart rate of the bar-headed goose does not change, and the body temperature also drops during flight.

Everyone who has been to Mount Everest has experienced altitude sickness. In recent years, there have also been many expeditions that have dreamed of crossing Mount Everest. Among the many expeditions, some succeeded, while others lost their lives in the process.

The biggest difficulty encountered in climbing Mount Everest is that humans often experience severe altitude sickness. However, in nature, there is a bird that is able to fly over Mount Everest, and it does not appear to be high. It is the bar-headed goose in nature.

Many people may be very curious, why the bar-headed goose in nature can fly over Mount Everest without fear of altitude sickness? The main reason why the bar-headed goose in nature is able to fly over Mount Everest without altitude sickness is because its body has two different metabolic patterns

1. Bird migrationIn nature, most birds will carry out a kind of migration activity every winter. For most birds, migration is a very difficult task, but this difficult thing is one of the things they have to do every season. The main reason why the migration of birds in nature is a difficult thing is that they may have to fly over the world's peaks due to the need for routes during their migration.

2. Introduction to the Bar-headed Goose In nature, the Bar-headed Goose needs to migrate once a year. Every migration of these birds is extremely difficult, as they have to fly over Mount Everest. To be precise, in autumn, the bar-headed goose will start migrating from the Qinghai region of China and fly all the way, eventually crossing Mount Everest to some of the warmest lakes in southern India for the winter.

In the following spring, the bar-headed geese will return to southern China along the way.

3. SummaryThe reason why the bar-headed goose does not experience altitude sickness when flying over Mount Everest is mainly because it has two completely different metabolic modes. Whenever the bar-headed goose flies to the plateau, it adjusts its body's metabolic patterns to adapt to changes in the environment.

For the bar-headed geese, they usually fly higher than Mount Everest, so they are used to it, and it is very simple and easy for them.

Because the bar-headed goose has long adapted to the thin environment at high altitude in the long-term evolution, it can easily fly over Mount Everest.

Because they have adapted to the living environment of the plateau and evolved genes suitable for survival on the plateau, altitude sickness does not occur.
