Chapter 37 Bully Bully

   "This bullhead bird! It's too outrageous!"

  Below Zhao Meng,

  A bullbird is beating a robin.

  As for why the bullhead hit the robin, it was because the robin fed the bullock's chicks to death.

  I saw the robin chirping and fleeing.

   And the bullhead still refused to let it go,

  It throws out all the remaining eggs in the robin's nest,

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

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

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

   "This **** is 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, has been following the bullbird, looking for the reason why the brown-headed cowbird won.

   And this process took more than half a month,

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

  Secretly lay eggs in the robin's nest, implementing 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 been parasitized before to explore the hatching status,

  From here on, the brown-headed cowbird and the cuckoo have different behaviors.

  After cuckoos play nest parasitism, they generally let it go, leaving their offspring in a state of resignation.

  But the bullhead bird will return to the previous nest to check the condition of its offspring.

   At first Zhao Meng didn’t understand this kind of behavior,

  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 parasitize the nest 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 does the bullbird attack the robin and its nest after seeing its chicks die?"

   "Such a bully's behavior, is it just for revenge?"

   Such a thought flashed through his mind,

  But he rejected it again,

  Birds have a fast metabolism, 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 the bird very well.

   But even if he knew about birds, he still couldn't figure out what the bullhead bird was doing by flipping the table.

  With doubts, Zhao Meng continued to follow the bullhead bird.

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

   While tracking the bullbird,

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

  Maybe because rebuilding the nest was too hasty,

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

  Besides, Zhao Meng also observed a more terrifying phenomenon.

  Perhaps because of rebirth, resulting in nutritional deficiencies, the newly born chicks of the robin cannot compete with the chicks of the bullhead bird at all.

   There were one or two chicks in the last nest competing with the bullbird's chicks.

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

   During 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 are left with their mouths open, looking like they are waiting to be fed.

   "This bull-headed bird is too bad!"

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

  He thought the cuckoo bird was bad enough,

   I didn't expect there to be something worse than the cuckoo in nature.

  …

  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 the calculation is based on the survival rate of the chicks, this simulation has failed!"

   "What would happen if the bullhead was killed in the first place?"

  At this point the situation has become a foregone conclusion,

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

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

  Of course cheating is secondary, Zhao Meng mainly sees the bird as 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 bleeding 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

   "Looks like cheating is a dead end!"

   "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 dominant bird in that jungle is the robin!"

  “The robin has a strong anti-parasitic ability, and it is very difficult to not be found after laying eggs in it!”

   "And the robin's nest is different from the general bird's nest. 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..."

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

  After reviewing the brown-headed cowbird's reproductive strategy, he found that attacking the nest has many benefits.

  "The 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 want 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.

  Natural wildness dominates everything.

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

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

  …

  During Zhao Meng’s simulation,

  Bai Geng walked in from outside the courtyard. He was about to say something when he saw Zhao Meng closed his eyes, as if he was doing some kind of cultivation.

   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.

   At present, more than 210 species of brown-headed cowbirds have been identified as parasitic species.

   Some brown-headed cowbirds even lay their eggs in the nests of hummingbirds and birds of prey,

   A brown-headed cowbird can lay 36 eggs a season.

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

   If they find that their eggs have been abandoned, they may attack the bird's 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,

   85% of the brown-headed cowbirds will lay eggs again after the parasitic bird rebuilds the nest.
