Chapter 861 Great Migration of Animals

On the grassland, Bi Fang led Harley towards the north.

Sparse yellow hay reaches up to his thighs.

If you wear shorts and have delicate skin, you will definitely be covered with white marks after a hike. If you are unlucky and run into thorny plants, blood marks are inevitable.

If it is poisonous, it is even possible to hit GG on the spot.

What Bi Fang said about teaching something different has not yet had a chance to be reflected.

I just chatted with the audience during the hike, introducing some of the features of the African savannah, as well as some of the food and scenery they might encounter at this time.

"Actually, early October is a very special node for the African grasslands in the northern hemisphere. During this time period, we can see many things that we cannot usually see. It can be said to be the best time period."

【How to say?】

【Is it the great migration of animals?】

[I have been to Kenya. The Great Migration usually starts in June and July and ends completely in September. It is already October now. How can we still see the Great Migration? 】

"If we talk about the Great Migration, it usually starts in June or July." Bi Fang, who saw the barrage, admitted this point without hesitation, but then smiled again, "But the Great Migration comes quickly. Come back."

It’s also fast.”

"It's true that we couldn't see how the animals migrated there. It was a few months late, but how they came back, we can see clearly now, which is just right."

Kenya has a special geographical location.

It belongs neither completely to the northern hemisphere nor completely to the southern hemisphere, but spans north and south, with the equator in the middle.

This also means that when the northernmost part of the Kenyan grassland is in the dry season and the earth is dry, the southernmost part of the Kenyan grassland may be in the wet season and the water and grass are luxuriant.

Such significant differences create the most shocking scene in nature - the great migration of animals from north to south.

The dry and wet seasons in the African savannah are the same as the summer periods in each hemisphere.

Therefore, starting from mid-to-late May every year, the Serengeti National Park in northern Africa is about to usher in its dry season.

During this period, the aquatic plants in the park gradually withered, and the lack of food could no longer meet the needs of the large number of herbivores.

In addition, the timing is very coincidental.

Spring is here, everything comes to life, and it's the season for animals to have sex with each other again.

Anyone who has seen the animal world will be familiar with this sentence.

For most herbivores, their breeding season is concentrated between March and May every year.

Herbivores on the African savannah are no exception.

Survival and reproduction are the instincts of every living thing.

The so-called estrus seems to be a violation of the biological reproductive instinct.

Some people believe that if animals could reproduce all year round like humans, the number of such animals would be greatly increased.

However, this idea is wrong.

In fact, the estrus period of animals is not to limit the population, but to improve the survival rate of offspring and increase the population.

The laws of nature are very different from those of human society. In nature, "survival of the fittest" is an eternal truth.

In spring, everything revives, the temperature is suitable, and the comfortable environment provides shelter and food for animals.

Most animals also choose to be active during this season and then give birth in the summer.

In summer, the plants are in bloom and the climate is more suitable.

If you give birth to cubs in winter, there is a high chance that the cubs will freeze to death due to insufficient food.

With sufficient food, herbivores become more active. Based on this, it becomes easier for carnivores to hunt, so that the offspring of both species can survive better.

Mating and reproduction are extremely physically demanding things. Some extreme animals will choose not to eat at all during pregnancy while waiting to give birth. After giving birth, most female animals are also in a weak state and need to be nursed back to health in time.

It is said that good steel should be used on the blade, and the same principle applies to animal reproduction.

Therefore, all energy must be saved and released in spring when the survival rate is highest.

Of course, not all animals choose to be active in spring. This is actually related to the animal's pregnancy period. For example, deer are active in autumn.

Since deer have a long gestation period, they can give birth to calves in spring after being active in autumn. In fact, the above rules are followed.

The coming of drought.

The number of ethnic groups increased dramatically.

The two reasons are superimposed, and the balance of supply and demand is seriously broken.

In order to survive, the herbivores had to start migrating to the northwest of the Serengeti, just to chase the grass and water.

The herbivores disappeared, and the carnivores were no exception. Then, under the influence of the food chain, almost all creatures, large and small, had to move.

Such a scene is very spectacular.

Millions of wildebeests, hundreds of thousands of zebras, and antelopes form a massive procession, traveling north from the Serengeti Reserve in Tanzania and ending in the Masai Mara National Park in Kenya, trekking more than 3,000 kilometers.

On the way, you not only have to cross the grasslands where lions and leopards ambush, but also beware of jackals that may appear at any time and the crocodiles gathering on both sides of the narrow Mara River. These predators are ready to share the upcoming feast.

A large number of animals cross the border, cross the Mara River, and come to the Masai Mara. This situation will continue until September or even October every year.

Even if it can be seen now, it may only be a few scattered small groups, and it cannot be called a great migration at all.

[But why can I see the return journey? 】

[Will this live broadcast take several months? 】

Bi Fang shook his head: "Of course not. We can see the return journey because this kind of animal migration is not like migratory birds, which leaves in autumn and returns in spring, but only stays for less than a month."

"Because soon, the prairies of the southern hemisphere will also enter the dry season."

"And the Maasai Mara National Park, where the animals migrate, is only one-tenth the size of the Serengeti."

"It's simply not enough to sustain large numbers of herbivores."

“Beginning in mid-October, when the rainy season returns to the Serengeti savanna in Africa, the grass begins to turn green under the moisture of the rain.”

"At this time, the animals after a short period of refuge have to move back to the Serengeti. The whole process lasts about a month and basically ends in December every year."

"In December, the animals return to their homes and begin to reproduce and recuperate, gradually replenishing the number of similar animals lost along the way and preparing for the next year."

"Among these millions of migration teams, only 30% of the lucky ones can return to their starting point, and with them, there are 400,000 new lives born during the thrilling journey."

"So, in a dozen days, we may be lucky enough to see this shocking scene."

[Good guy, if you are unlucky, you will have to rush back just as you passed by (dog head)]

[Not necessarily, everyone is back, there will be less people eating grass, maybe it will be just right (dog head)]

[Speaking of which, we can still see the great migration of animals]

【Great!】

[It’s forbidden to do so]

Looking around, all the grass is withered and yellow, without a trace of life.

The earth is very hard. Although there are no cracks, this is also a reflection of the lack of moisture.

If there is sufficient water, the ground should not be as hard as cement, but rather soft and able to clearly leave footprints.

But now, even the car passing by the conservation center cannot leave any trace, which shows how hard the land has become due to lack of water.

However, you can still occasionally see animals passing by on the grassland.

There was a chirping sound in the grass, and a brown mouse disappeared into the narrow rock cave, leaving only Harley who was digging ineffectively at the entrance of the cave.

After walking for several hours, Bi Fang could clearly feel that his lips were getting dry.

Harley, who had not caught the mouse, began to look impatient. He began to lean towards Bifang and tried to "lie down".

Cheetahs are creatures that don't like to walk long distances, and it showed quite clearly at this moment.

Facing Bi Fang who was still moving forward, Harley, who had failed to lie down several times, quickly took a few steps forward, walked to Bi Fang, lay down directly on the ground, and did not get up even though Bi Fang walked by.

He just raised his chest and screamed a few times on the ground.

【I can’t walk anymore】

【Is it impossible now? 】

[Displayed (eating watermelon)]

Bi Fang smiled and did not force himself. Instead, he looked around and found a small slope. He ignored the cheetah on the side and walked straight towards the slope.

Harley on the ground raised his head and looked, but his eyes were blocked by the grass. After waiting for a while, Bifang was not seen, so he had to stand up. Only then did he see Bifang standing on the slope, and ran away quickly.

Go over there and continue to the ground.

But at this time, Bifang really grabbed the back of its neck and dragged it to the hillside.

"Cheetahs lie down most of the time. During the hottest times of the day, they are least active and rest under the shade of large trees."

"Although the weather in Kenya is not very hot, it does not affect its tendency to lie down. They also do not like long-distance expeditions. They really should take a rest now."
