"This cow-headed bird! It's too outrageous!"
Below Zhao Meng,
A cowbird is beating a robin.
As for why the cowbird shot the robin, it was because the robin fed the cowbird's chicks to death.
I saw the robin chirping and fleeing.
But the cow-headed bird still refused to give up.
It threw all the remaining eggs from the robin's nest,
Then one "foot" knocked over the robin's nest.
Zhao Meng was stunned for a long time after seeing this scene. He finally came to his senses when he heard the sound of the cow-headed bird flapping its wings to fly away.
Looking at the cow-headed bird flying away, Zhao Meng held it in for a long time before he finally said:
"This is called nest parasitism!"
Zhao Meng felt that his three views had been subverted. Did such a bird really exist in his previous life?
…
Zhao Meng, who hurriedly entered the second simulation, followed the cowbird to find the reason why the brown-headed cowbird won.
And this time it took more than half a month,
At first, the cowbird behaved quite normally, foraging with the robins, changing the color of its eggs,
Secretly lay eggs in a robin's nest to carry out the process of nest parasitism.
It wasn't until the cowbird chicks began to hatch that the brown-headed cowbird's behavior became a little weird.
The bird begins to return to its previously parasitized nest to explore the hatching situation.
From here on, the behavior of the brown-headed cowbird and the cuckoo begins to diverge.
After cuckoos parasitize their nests, they usually leave their offspring alone and resign themselves to their fate.
But the cowbird will return to its previous nest to check on the condition of its offspring.
At first, Zhao Meng didn’t understand this behavior.
But soon, he discovered that some robins have strong anti-nest parasitism capabilities.
Once a robin discovers something is wrong with an egg in its nest, it will peck it out and throw it away without hesitation.
In this case, the cowbird will parasitize the nest again to replace the eggs that were thrown away.
After observing this situation, Zhao Meng finally understood why the score between himself and the Bull-headed Bird was so different.
He underestimated the robin's reaction.
Although he understood this, he could not understand what happened just now.
"Why would this cowbird attack a robin and its nest after seeing its chicks die?"
"Is such a bully's behavior just for revenge?"
Such thoughts 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 status of birds very well.
But even if he knew about birds, he still couldn't figure out why the bull-headed bird flipped the table.
With doubts, Zhao Meng continued to follow the Bull-headed Bird.
Fortunately, many phenomena in the biological world can always be discovered through patient observation and analysis.
In the process of tracking the cowbird,
He found that robins will rebuild their nests and lay eggs at a faster rate after discovering that their nests have been destroyed, and cowbirds will take the opportunity to lay eggs in new nests.
Perhaps it was too hasty to re-establish the nest,
The robin's ability to identify eggs has decreased, and the process of parasitizing new nests is exceptionally smooth.
In addition, Zhao Meng also observed an even more terrifying phenomenon.
Perhaps due to lack of nutrition due to another birth, the newly born chicks of the robin simply cannot compete with the chicks of the cowbird.
There were one or two chicks from the previous nest competing with the cowbird chicks.
But these chicks in the new nest are easily squeezed out of the nest.
Within a day or two after a cowbird chick is born,
All the chicks and unhatched eggs in the nest have disappeared.
Only the cowbird chick was left with its mouth open, looking like it was waiting for food.
"This cow-headed bird is too bad!"
Zhao Meng sighed in his heart after completely observing the reproductive strategy of the Brown-headed Cowbird.
He originally thought the cuckoo bird was bad enough;
Unexpectedly, there are creatures worse than cuckoos in nature.
…
Summer is coming again,
Zhao Meng, who had not laid many eggs, looked at the cow-headed bird on another branch and had some thoughts in his mind.
"If calculated based on the survival ratio of chicks, this simulation has failed!"
"What would happen if the Cowbird was killed from the beginning?"
At this point the situation has become a foregone conclusion,
But Zhao Meng still wanted to give it a try and see if there would be any punishment for killing this hateful cow-headed bird.
If there is no punishment, then he may be able to use some means to cheat in the next simulation.
Of course, cheating was secondary. Zhao Meng's main reason was to see that the bird was uncomfortable.
…
…
Three days later,
[Simulation failed! 】
Looking at these words, Zhao Meng sighed:
"As expected, there are still restrictions!"
At this time, Zhao Meng's paws were stepping on a bleeding bird corpse.
Neither he nor the Cow-headed Bird are birds of prey, but as a human, he knows how to use tools, so it is not difficult to kill the Cow-headed Bird.
The consequence of killing the cow-headed bird is to directly determine that the simulation has failed.
"It seems that cheating is out of the question!"
"Can I just lay eggs honestly?"
Zhao Meng's consciousness returned to his body again, and this time he was not in a hurry to start the next simulation.
Instead, he opened his eyes, found some pen and paper and summarized something.
“The main bird in that jungle is the robin!”
"And robins are very anti-parasitic. It would be difficult to lay eggs in them without being discovered!"
"And 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 discovers that its offspring are not born normally, it will destroy the nest and turn over the table..."
After summarizing this, Zhao Meng discovered that the simulation of Du Juan's second eye was not simple.
After reviewing the reproductive strategies of brown-headed cowbirds, he found that attacking nests has many benefits.
"A nest built in a hurry is more loose, and it is easier for one's own offspring to exclude other nestlings!"
"Should I also learn from the cow-headed bird?"
"Not only do you want to use the nest to lay eggs, but you also want to beat up the owner of the nest!"
"this……"
Zhao Meng's sense of morality was somewhat resistant to this approach.
But he has had many experiences of not being a human being.
It is very clear that in the cruel biological world, the so-called justice and morality of human beings have never existed.
Natural wildness 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 these two weeks?"
…
When Zhao Meng was conducting the simulation,
Bai Geng walked in from outside the courtyard. He was about to say something when he saw Zhao Meng had his eyes closed and seemed to be practicing some kind of practice.
He didn't make a sound, but quietly waited for Zhao Meng to wake up.
