With the arrival of winter every year, the animals have also embarked on a spectacular migration journey, from the sea, land and air, across the long journey, all the way to the wintering ground!
The first to embark on the migration route is the crane known as the "Boudoir Crane" and the smallest crane in the world, the Crane of the Dragon Feather. It chooses to travel "civil aviation", but also "self-driving".
Don't look at their small size, the altitude of flight is incredible! They have to fly over the Himalayas, so their "migration routes" are known to be one of the toughest journeys in the world.
Why?
Their journey is really accompanied by cold temperatures and storms!! What's more, there are natural enemies along the way! It is the famous aerial hunter - the golden eagle. The weak feather crane may not have thought that it has escaped high altitudes, passed through the storm cold current, and suffered from low temperatures, but it may still become the "dish food" of the golden eagle!
After talking about the migration journey of the crane, we will turn our eyes to the Arctic ice field, is there also a "migration army" here?
A must! Every year, the world's most spectacular migration story is staged here, and the protagonist of the story is the famous reindeer. But they don't fly like in fairy tales, and their "migration" uses the most common walking.
It migrates about five or six thousand kilometers a year, and its lifetime migration distance can be connected to three circles around the earth, and they are the world's longest migratory land mammals.
Like a moving forest, the Arctic ice field leaves the back of their starry night and hurried "migration"!
In order to overcome the endless snow field, they evolved ultraviolet vision, so that they are not afraid of snow blindness. Even more amazing is to be able to eat food under the snow without freezing the nose, their red noses are extremely well-developed in the blood vessels, and it is even more obvious under the infrared camera, no wonder they have red noses in fairy tales.
Finally we came to the top of the ocean, where there is also a group of magical friends who are embarking on the "migration road", which is the manta ray known as the "manta ray".
Manta rays migrate over the sky and gallop through the oceans, and it is clear that the "migration" they chose was to travel by water.
Unlike the crane and reindeer, the migration path of the manta ray is more romantic and enjoyable, and they can "talk about love", enjoy the food, and enjoy the "care service" of the body after a full meal when passing through their "station"! There are many "fish doctors" in the "caravanserai" who will do their best to wait for the manta ray army to comfortably go on the road, and along the way, there are inseparable "hitchhiking masters" with them- the bass, which also solves the boredom of the long journey.
During the journey, the manta rays will also show their "volleying" leaping skills from time to time. Why are they doing this? The show will reveal more strange and interesting stories about their migration.
Animals marvel at the great migration, lock the "Science Zoo", not to see oh!
Health tips: Please wear a mask, wash your hands frequently, ventilate more, and go to crowded places less.
