Simulation: Start with exotic animals

Chapter 37 Bully Bullock

"This bull-headed bird! It's too outrageous!"

Below Zhao Meng,
A bullbird is beating a mockingbird.

As for why the minotaur beat the robin, it was because the robin fed the minotaur's chicks to death.

All I saw was the robin chirping and fleeing.

And that bullbird still refuses to let it go,
It threw out all the remaining eggs in the robin's nest,

Then with one "foot" it kicked over the robin's nest.

Seeing this scene, Zhao Meng was stunned for a long time, and he came back to his senses when he heard the sound of the tauren flapping its wings to fly away.

Looking at the bull-headed bird flying away, Zhao Meng held back for a long time before choking out a word:

"It's a fucking nest parasite!"

Zhao Meng felt that his three views had been subverted. Did such a bird really exist in his previous life?
……

Zhao Meng, who hastily entered the second simulation, followed the bullbird all the time, looking for the reason why the brown-headed cowbird won.

And this is more than half a month,

At first, the behavior of the bullbird was normal, foraging with the robins, changing the color of the eggs,

It secretly lays eggs in the robin's nest and implements the nest parasitism process.

It wasn't until the chicks of the bullbird began to hatch that the behavior of the brown-headed cowbird became a little weird.

The bird began to return to the nest where it had previously parasitized to check the hatching status,
From here on, the brown-headed cowbird and the cuckoo behave differently.

After cuckoos play nest parasitism, they generally let it go, leaving their offspring in a state of resignation.
But the bullbird will return to the previous nest to check the status of its offspring.

Zhao Meng didn't understand this kind of behavior at first,

But soon, he discovered that some robins have a strong anti-nest parasitic ability.

Once the robin finds that there is something abnormal about the egg in the nest, it will not hesitate to peck it and throw it out.

In this case, the bullhead bird will carry out nest parasitism again to make up for the eggs that were thrown out.

After observing this situation, Zhao Meng finally understood why the score difference between himself and the Bullhead Bird was so large.

He underestimated the robin's reaction.

Although he understood this, he couldn't understand what happened just now.

"Why did the bullbird attack the robin and its nest after seeing its chicks die?"

"Is such a bully's behavior just for revenge?"

Such a thought flashed through his mind,

But he rejected it again.
The metabolism of birds is very fast, which determines that the behavior of many birds is efficient and purposeful, and they will not do some useless work.

Zhao Meng, who has been a bird several times, knows the state of birds very well.

But even if he knew about birds, he still couldn't figure out what the reason for the bull-headed bird's behavior of flipping the table was.

With doubts, Zhao Meng continued to follow the bull head bird.

Fortunately, there are many phenomena in the biological world, only by patient observation and analysis, some clues can always be found.
In the process of tracking the bullbird,

He found that robins rebuilt their nests to lay eggs at a faster rate after they discovered that their nests had been destroyed, and the bullbirds took advantage of the opportunity to lay eggs in new nests.

Perhaps because rebuilding the nest was too hasty,

The robin's ability to discriminate eggs has declined, and the process of parasitizing new nests has been exceptionally smooth.

In addition, Zhao Meng also observed a more terrifying phenomenon.

Perhaps it was due to the lack of nutrition due to rebirth, the newly born chicks of the robin could not compete with the chicks of the bullhead bird at all,
There were also one or two chicks in the previous nest competing with the bullbird's chicks for one or two.

But the chicks in the new nest were easily pushed out of the nest.

In the first day or two after the birth of the minotaur chick,
The chicks and unhatched eggs in the nest have all disappeared,
Only the chicks of the bullbird were left with their mouths open, looking like they were waiting to be fed.

"This bull-headed bird is too bad!"

Zhao Meng, who completely observed the brown-headed cowbird's reproductive strategy, sighed in his heart.

He thought the cuckoo bird was bad enough,
Unexpectedly, there are worse existences in nature than cuckoo birds.

……

Summer is coming again,

Zhao Meng, who hadn't laid much eggs, looked at the bull bird on another branch, and some thoughts came to his mind

"If calculated based on the proportion of chicks surviving, this simulation has failed!"

"What would happen if the bullhead bird was killed at the beginning?"

At this point the situation has become a foregone conclusion,

But Zhao Meng still wanted to give it a try, to see if there would be any punishment for killing this nasty bull bird.

If there is no punishment, then he may be able to use some means to cheat in the next simulation.

Of course cheating is secondary, Zhao Meng's main reason is that the bird is uncomfortable.

……

……

Three days later,
[Simulation failed! 】

Looking at these words, Zhao Meng sighed:
"Sure enough, there are still restrictions!"

At this time, Zhao Meng's paws were stepping on a bloody bird corpse.

Neither he nor the bull-headed bird is a raptor, but as a human being, he knows how to use tools, so killing the bull-headed bird is not difficult.

The consequence of killing the bullhead bird is to directly judge that the simulation failed
"It seems that wanting to cheat is impossible!"

"Can't I just lay eggs honestly?"

Zhao Meng's consciousness returned to his body again, this time he was not in a hurry to start the next simulation,
Instead, he opened his eyes and found some pens and paper to summarize something.

"The chief bird in that jungle is the robin!"

"And the robin's anti-parasitic ability is very strong, it is very difficult to not be found after laying eggs in it!"

"Moreover, the robin's nest is different from ordinary bird's nests. It has a nest edge structure. It is not easy for one's own chicks to push other chicks out!"

"More importantly, once the brown-headed cowbird finds that its offspring have not been born normally, it will show the behavior of destroying the nest..."

After summing up to this point, Zhao Meng discovered that the simulation of Dujuan's second-week goal is not easy.

After reviewing the breeding strategy of brown-headed cowbirds, he found that attacking nests has many advantages.

"Nests built in a hurry are more loose, and their offspring are more likely to exclude other chicks!"

"Should I also learn from the bull-headed bird?"

"Not only do you have to use the nest to lay eggs, but you also have to beat up the owner of the nest!"

"This……"

The moral sense in Zhao Meng's heart is somewhat against this approach.

But he has already had many inappropriate experiences,

It is very clear that in the cruel biological world, the so-called justice and morality of human beings have never existed.

The wildness of nature dominates everything.

Thinking of this, Zhao Meng took a short rest, closed his eyes, and prepared to start a new simulation.

"I don't know, what kind of entries will be unlocked in the second week?"

……

When Zhao Meng was simulating,
Bai Geng came in from outside the courtyard. He was about to say something when he saw Zhao Meng closed his eyes and seemed to be practicing some kind of practice.

He didn't make a sound, but quietly waited for Zhao Meng to wake up.

　Note:

　　The brown-headed cowbird is a nest-parasitic bird that lays its eggs in the nests of other passerines.
　　So far, more than 210 species of brown-headed cowbirds have been identified as parasites.
　　Some brown-headed cowbirds even lay their eggs in the nests of hummingbirds and birds of prey,
　　A single brown-headed cowbird can lay 36 eggs a season.

　　In addition, brown-headed cowbirds do not just fly away after laying eggs, they will periodically return to the nest where they laid eggs to check on the situation.

　　If you find that your eggs have been abandoned, you may attack the nest, or even directly destroy the host's nest, forcing them to rebuild the nest and lay eggs again.

　　According to subsequent follow-up observations,
　　Eighty-five percent of the brown-headed cowbirds laid eggs again after the parasitic bird rebuilt the nest.
