Has cuckoo bird parasitism ever been discovered, cuckoo parasitism

When cuckoo birds are parasitic, they may be discovered.

When the cuckoo bird is parasitic, it may be found, and if it is found, its eggs will be easily thrown away or eaten. However, as long as the bird has been hatched into a young bird, it is rare to be expelled, which is also the result of natural selection, so the chance of being found is also very small. The species of cuckoos are different, some are non-parasitic, and some choose multiple parasitism.

The cuckoo is very smart, and when it is looking for a nest, it will find a nest that is more similar to its own eggs and put it in, so that the mother bird in the trough cannot distinguish it.

After the cuckoo eggs are hatched, the chicks will squeeze out all the other eggs, and the chicks will also take the initiative to adapt to the living habits of the nest mother, and the nest mother will not be able to tell whether it is her own child. As long as it is hatched, the chances of being found are slim.

Cuckoo eggs will be spotted by various birds, and will be eaten or thrown away after being recognized.

For example, the brown-headed wren warbler cannot identify alien eggs that are similar to their own. However, their eggs are colored and have a variety of patterns on them, so they rely on this method to distinguish cuckoo eggs that are quite different from them. Red-faced fantail warblers are better at using their eyesight to identify exotic eggs, but their own eggs do not change much in appearance.

In fact, not all cuckoo birds are unwilling to raise children or make nests, some cuckoos living in India and the American continent will also make nests and raise children with their own hands and responsibilities, but there are some species of cuckoo birds that have ruined the reputation of the entire population, such as the Cuckoo Kui's rhododendron, the yellow-billed cuckoo, the large spotted cuckoo, etc.

Explanation of cuckoo nest parasitic behavior

The parasitic behavior of the nest is manifested in the selection of hosts: the large cuckoo is looking for a host similar to the hatching and brooding period, the nestlings have basically the same feeding habits, and the oval shape and color are easy to imitate, and most of them are passerinees.

In terms of parasitism, the large cuckoo mostly produces eggs quickly before the host starts to incubate eggs, and when the host leaves the nest. In late spring and early summer, it flies north. It does not make its own nests and does not hatch eggs, laying an average of 2-10 eggs per year, but it lays eggs in the nests of thrushes and reeds, and allows these birds to carefully incubate them for themselves.

And it only produces one nest per nest it flies to.

The cuckoo is actually a very domineering bird, the cuckoo does not build its own nest, and even after laying eggs, it will be placed in the nests of other birds for incubation, especially when the pregnant cuckoo is about to lay eggs, it will look for the nests of various birds everywhere. The cuckoo is also very smart, it will look for some nests with eggs to lay eggs, after laying eggs, the cuckoo will take 1 or 2 eggs from the nest when the mother bird is not paying attention, so that the number of eggs in the nest does not change.

Cuckoos will put their eggs in the nests of other birds, and then mix together, which looks very similar on the surface, and if you don't look closely, you really can't see it, so there are many bird mothers who don't know that their eggs have been replaced, and still work hard to hatch these eggs. But under the hatching of the mother bird, the first to emerge from the shell is often the cuckoo's child, and the baby cuckoo is also as domineering as its mother's temper, and will snatch the food of the mother bird as soon as it is born. Even, they will go to squeeze out other eggs in the nest, and some of the hatched birds will not be able to compete with the little cuckoos, and will eventually starve to death due to lack of food.

However, some mother birds still think that the baby cuckoo is their child, and think that it is their own flesh and blood, so they also take care of it wholeheartedly in terms of feeding. As the baby cuckoo grows bigger day by day, the mother bird also has to catch more food to feed them, but in the end, the baby magpie will grow bigger than the mother bird, and when the feathers are full, the baby magpie will fly away.

Most birds don't kill these young, although some mothers are not sure if they are their own children, but they do not dare to risk killing them, because if they kill the wrong ones, they are likely to hurt their real children. Of course, this is not absolute, there are some birds that are relatively large, or have a domineering personality like cuckoos, and cuckoos are not allowed to send their children down to their nests, of course, if they are discovered, they will also kill and drive them away.

No, this kind of way of occupying other people's nests is only made by the cuckoo, and the other birds will not kill them even if they find it, because those birds have their own nests, and they do not dare to poison the cuckoo.

Other birds don't choose to kill even if they find it, because most birds can't tell if it's their own child, but this practice of cuckoo birds is really annoying.

Most of them won't. Because of the cuckoo himself, after he gave birth, he would take care of it in time and feed his baby. And the other birds can't bear to hurt them.

Sometimes cuckoo eggs can be recognized, and in the documentary "Wild Austria", a reed warbler found that the cuckoo laid its eggs in a nest made by herself, so she pecked the cuckoo's egg with her beak. However, it is rare for "cuckoo eggs to be unrecognized, but hatched cuckoo chicks to be recognized", on the contrary, it is the cuckoo chicks that kill the biological children of their adoptive parents.

Although the cuckoo will nest with other young birds during the feeding period, it is a beneficial bird that preys on forest caterpillars, forest caterpillars except for cuckoos, there are no natural enemies, it can be said that the cuckoo is the protector of the forest from pests.

There are many aliases of the cuckoo, such as Zigui, Du Yu, etc., in ancient Chinese poetry, Zigui bird is often appeared, such as "Yang Hua falls to the end of Zigui", "and smell Zigui crying night moon", etc., it can be seen that this bird has always been highly respected by people, and even considered an auspicious bird, but in fact, the beauty of the cuckoo only stays on the surface, but it retains a very vicious gene in its body.

Based on the dark history of this bird, I speculate that there is a good chance that this will happen.

The dove occupies the [dove] in the magpie's nest, including the cuckoo, since it can forcibly occupy people's houses, who dares to guarantee that it will not eat other people's meat. It's better to be careful.

It is amazing that cuckoos lay their eggs in other birds' nests and let other birds hatch and feed them on their behalf.

According to the data, about one-third of cuckoo birds reproduce in a parasitic way. It will choose the time of spawning, the time of incubation, the size of the egg, and the appearance of the bird similar to their own eggs, and will take away one or all the eggs in the parasitic nest before laying eggs, so that their eggs can hatch to gain a survival advantage, the cuckoo bird only secretly in the host's nest, quickly lay an egg, and even after the cuckoo hatchling, it will push other eggs in the nest or the host young bird out of the nest and monopolize the food, so as to obtain the greatest right to survive.

All this is in the precise calculation, if human society is used to regulate its behavior, fraud, embezzlement, **, and crimes are all included.

Could it all be the result of biological evolution? Or is it wisdom that leads the cuckoo bird to perform these acts? Why don't two-thirds of the other cuckoos behave in this way? So why haven't other birds evolved this behavior?

This kind of calculating wisdom is comparable to some behaviors in human society. Who exactly taught a third of the cuckoo birds to make "bad"?

In late spring and early summer, when you visit the scenic area, you can often hear "cuckoo! Cuckoo! This sound is made by the cuckoo, crisp and melodious, melodious, pleasant, people call it "cuckoo".

The cuckoo is an ordinary member of the bird family, but people have a lot of criticism about it.

Aristotle, the famous Greek philosopher, wrote in his famous work "Zoology": "The cuckoo is known for its cowardice among the flocks of birds, and when the birds gather together to peck at it, it will flee." "Why did the cuckoo run away?

Naturally, it understands that it has done something wrong. Someone selected the top 10 cheaters in the animal kingdom and tied a list, and the cuckoo was at the top of the list.

Some people say that the cuckoo is a rogue among birds, a big **. The cuckoo is too lazy to make a nest, and likes to lay its eggs in the nests of other birds, and other birds help it hatch and feed its offspring. The reed warbler is often deceived by the cuckoo into raising children for the cuckoo.

The cuckoo is a master of camouflage and destroys an egg in the reed warbler's nest, which it then stores in its own nest. Its eggs are enough to confuse the real thing, and the reed warbler has not the slightest doubt. Scientists removed cuckoo eggs from the reed warbler's nest, and within a few days, they discovered that many of the nearby nests had been damaged by the cuckoo.

In doing so, the cuckoo is clearly warning the other birds that they will refuse to help it incubate its eggs'Price.

The cuckoo's young birds are very ** and openly do bad things in front of their "adoptive parents". The little cuckoo is not only gluttonous, but also squeezes all the siblings born to the same nest foster parents out of the nest and falls to death, enjoying the grace of the adoptive parents alone. The poor reed warbler had to run around in search of food for the baby cuckoo.

The reputation of the cuckoo is really bad. In the UK, the cuckoo bird is synonymous with "madman, madman, stupid thing, ugly thing". In the 70s of the 20th century, there was a movie "Flying Over the Cuckoo's Nest" in the United States that reflected social pathology, which equated the cuckoo's nest with an insane asylum.

The film also won the 48th Academy Award for Best Picture in 1975.

In fact, Nabi, the cuckoo bird is not a "bad bird", and its behavior has a certain adaptability and survival strategy like other birds.

The cuckoo bird is a parasitic and reproductive bird that does not build nests, incubate eggs, and raise young birds, but instead places its own eggs in the nests of other birds for other birds to incubate and raise their young. This parasitic reproduction strategy is an adaptive measure adopted by cuckoo birds in order to survive in a competitive living environment.

The parasitic reproductive strategy of cuckoo birds can have certain effects on other birds, such as causing the destruction of nests, eggs, and young birds of other birds. But this is not a "bad behavior" of the cuckoo bird, but a survival strategy of its burrowed celery.

In addition, the survival of cuckoo birds is also affected by the ecological environment, and changes in the ecological environment will also affect their survival strategies and behaviors. Therefore, we should be kind to the survival strategies and behaviors of cuckoo birds, and respect and protect the natural ecological environment, so that all kinds of organisms can coexist in harmony in the natural environment.

From breaking the shell to leaving the nest, the adoptive parents foraged for the cuckoo and sheltered it from the wind and rain, completely unaware that their children had already been kicked out of the nest by the enemy!
