Zhao Meng once heard an idiom called dove occupies the magpie's nest.

Doves generally refer to turtle doves, which are pigeon-like birds.

The birds will drive away some of the smaller birds and occupy the property of those small birds for reproduction.

From the point of view of human morality,

This kind of bird's behavior can be considered very excessive.

But in the animal kingdom, there is one bird that behaves more badly than the turtle dove, and that is the cuckoo.

This bird does not nurse its own chicks.

Instead, the eggs are laid in the nests of other birds, and the other birds can hatch them on their behalf.

This phenomenon is known in biology as "parasitism"

[In the first month, due to its size, the nestle can no longer accommodate you, and you can only stand on the branch and receive the female bird's feeding. 】

At this time, Zhao Meng was standing on the branch next to the bird's nest,

And a sparrow with a few locusts in its mouth fell,

Zhao Meng instinctively opened his mouth,

The sparrow tilted its head and looked at the big mouth that could swallow itself,

There seemed to be some doubts in the little black bean-like eyes,

But in the end, the locust was put into the huge mouth and flew away from the nest to continue looking for food for "one's" child.

"Gotta get out of the nest quickly, or this sparrow will die of exhaustion!"

"The cuckoo is such an uncomfortable bird!"

[In the second month, your wings are growing, and the female can no longer nurse you, and you start foraging alone! 】

Because there is no female bird to teach cuckoo chicks to hunt skills,

So the only thing that cuckoos can hunt is some difficult insects in nature. Dangerous prey such as pine caterpillars and dance moths.

"It feels like eating spicy strips!"

Zhao Meng's experience in not being a human is already very sufficient, so he adapts to the eating habits of cuckoos quickly.

"From a human point of view, this cuckoo is a great bird!"

Zhao Meng looked at the pine caterpillars full of trees, and secretly sighed in his heart.

[The third month, eating, growing]

Zhao Meng's body was still growing, and he felt that the breeding period of this bird was approaching.

"Cuckoos don't have a long lifespan, this time if you are careful, you should be able to pass the simulation in one go!"

Looking at the reflection in the water below, Zhao Meng secretly thought about something in his heart.

[Fourth month, eating, growing, escaping predators]

As a small and medium-sized bird, cuckoos face many predators.

If he is a first-time bird, he may be accidentally poisoned by those elusive predators.

But he has already simulated a tasseled sandpiper and has evaded the kestrel many times.

In the face of the predation of these birds of prey, he has sufficient experience in coping with them.

"The only thing to watch out for is those predators on the ground!"

In this state of careful living,

Zhao Meng finally waited for the breeding period that he liked to see.

[In the fifth month, you have matured and started to follow the sound to find the female bird!] 】

"Cuckoo! Cuckoo! ”

"Sub-rules! Sub-rules! ”

The rhododendrons during the breeding season began to chirp in the mountain forest,

Their calls have evolved into two other aliases, namely the cuckoo and the zigui bird.

But this is just a name that human beings have incarnated through their own cognition.

And these voices reached Zhao Meng's ears, which meant something else.

"Come on! It's time to lay eggs! ”

It's like an old hen clucking after laying eggs.

Birds will also seek out males to give new life to their eggs before they are ready to lay new eggs.

And hearing the call of the hen,

Zhao Meng also responded a few times, which were translated into human words, which may be understood as:

"Don't worry, I'll do it too!"

……

However, the call of the female bird is not only heard by the male bird.

By the time he arrived at the source of the sound, several males had already gathered.

"Looks like we're going to have to fight again!"

Each male bird shows his posture,

It's like a man in the gym who sees a beautiful woman flexing her muscles.

Zhao Meng is just an adult male bird,

It's not as good as these old birds that have grown in one or two years.

But with human intelligence and a lot of inhuman experience, he began to provoke the males around the female and fight each other.

Taking advantage of the chaotic situation,

He crept closer to the female.

……

The cuckoo gives life to the eggs for a long time, lasting a full two minutes.

It's not that Zhao Meng wants to delay time for some purpose,

It is because this parasitic bird has some differences from other birds in terms of physiological structure.

After the incident, Zhao Meng did not run away immediately like most males in nature.

He and the female have an important task to complete.

He escorts the female and lays her eggs into the nests of other birds.

Zhao Meng and the female bird flew away from the woods,

And the males in the forest are still fighting......

[In the sixth month, the female successfully lays her eggs into the nest of the grey magpie. 】

Zhao Meng was letting off wind on the branches of a tree on the side, observing the surrounding movements.

Zhao Meng disagreed with the female bird to lay eggs in the gray magpie's nest.

Grey magpie as a small and medium-sized bird of the crow family,

Although it does not have the extremely high IQ of the crow.

But the IQ of this bird is not ordinary, laying eggs into the nest of gray magpies, Zhao Meng is a little worried, will it be discovered.

And just when Zhao Meng was secretly worried,

He noticed a gray figure flying in the distance,

He hurriedly reminded the female bird. And the female bird heard Zhao Meng's voice and immediately left the gray magpie's nest,

Zhao Meng watched from a distance and found that a green egg had appeared in the nest.

"Let's go!"

Zhao Meng and the female bird hurriedly flew away from the territory of the gray magpie,

Although he is much larger than the Grey Magpie, this crow bird, like his close relatives, is extremely aggressive.

It took a great deal of effort to lure him away from the nest and for the female to lay eggs in the nest of the grey magpie.

"Hmmm! And go on! ”

In the animal kingdom, most of the creatures adopt the strategy of polygenesis and multifertility.

In this way, the continuity of the species can be maintained to the greatest extent.

Cuckoo birds also use such strategies,

They lay eggs in different nests, which ensures the success rate of parasitism.

"Huh! The female has found a new nest! ”

Zhao Meng followed the female bird and flew in one direction,

With a female bird alone, there is a certain risk of quietly laying eggs into the nests of other birds.

Therefore, the male bird needs to take cover on the side,

or harass, or seduc, in short, so that the bird guarding the nest cannot notice the situation in the nest.

"Hiss~ The nest it chose this time is ......"

Zhao Meng looked in the direction where the female bird flew,

I saw an unknown tree covered in thorns,

It doesn't matter what the tree looks like.

The important thing is that this tree thorn is strung with the carcasses of many small animals,

There were sparrows, small snakes, small mice, ...... insects, some of the carcasses had dried up, and some had worms.

"Why is this female bird still flying upwards with an iron head, the birds in this place are not easy to mess with at first glance!"
