Cuckoos are widely distributed, why do some people think cuckoos are excessive?

Because cuckoos love to eat grain. The rice grown in the farmer's field attracts cuckoos to come and feed, so some people don't like it.

Because it often calls, in fact, the cuckoo is often said to be the cuckoo, which is generally a four-tone cuckoo and a two-tone cuckoo, and the call is particularly interesting.

Because this bird is always calling, and there is no time when it is tired, it is very noisy, and it also causes noise to many people.

Cuckoos are solitary and often move alone. Flying fast and powerful, often in a straight line. When flying, the wings vibrate with a large amplitude, but there is no sound.

During breeding, he likes to chirp, and often stands on the top branches of arbors and chirps endlessly. Sometimes it chirps at night or chirps while flying, and its cry is so loud and loud that it can be heard from a distance with its rough and monotonous sound of "cuckoo-cuckoo", which can be repeated 20 times a minute.

The cuckoo breeding season is from May to July. Courtship is when male and female birds hop up and down on tree branches, fly up and down, chase each other, and make a low "hoo-hoo-hu-" sound. After that, the female stands still on the branch, her wings are half drooping, her head is stretched forward, and the male flies to the female's back, trembling her wings and mating her tail.

After 2-3 minutes, the male flies away from the female, perches 30-40 meters away, and stops slightly to fly to the female.

I have also seen 3 large cuckoos chasing each other and competing for mates. The cuckoo does not have a fixed mate, nor does it nest and incubate its own eggs, but lays its eggs in the nests of various passerine birds such as the reed warbler, sparrow, gray magpie, shri, brown-headed jay, northern redstart, and brown fantail warbler, and these birds bring and nurture for it.

Many people say that cuckoos are "cruel", but what are the reasons? They never build nests, but after mating during the breeding season, they lay their eggs in the nests of other birds, allowing other birds to hatch them instead. If we just lay their eggs in the nests of other birds while other birds are not paying attention, we will naturally not feel that they are cruel, but can only feel that they are more "lazy", and even ignore their own children.

The cuckoo is the most familiar and unfamiliar bird, because from June to June every year, the cuckoo can be heard in many parts of the country"Cuckoo Cuckoo"The call is strange because most people only hear the cuckoo call and have not seen the real cuckoo. It has been said that the cuckoo is a very cruel bird.

They are widely distributed in Asia, Europe and Africa, and according to their distribution, cuckoos are divided into different subspecies (West China, East China, Xinjiang, and nominated subspecies).

The four subspecies of the rhododendron are all found in China, with the East China and named subspecies being the most common. In appearance, the cuckoo is similar to the turtledove, but it is larger in size, with an average length of about 30 cm. The wings and tail feathers of the cuckoo are mainly light black, the fur on the abdomen is grayish-white, with brown markings from the middle of the abdomen to the tail, and the claws are mostly yellow.

The cuckoo is one of a kind for us"Beneficial birds"Because its diet is mainly insects, therefore, the cuckoo's habitat is mainly forests (there are more insects), of course, in today's forests are becoming less and less, cuckoos often appear in the fields and trees in the countryside.

Because the places where cuckoos stay are mostly tall trees, so, most of the time we are"I only hear its voice, but I don't see its birds"。In China, there are four subspecies of cuckoos. Why do we only hear cuckoos calling in April-June every year?

As you may have noticed, cuckoo calls can only be heard for two or three months of the year, and most of the time before the wheat harvest.

After the wheat harvest, the cuckoo song is rarely heard. What's going on here? This has to do with two things.

First of all, most of the cuckoos distributed in China are summer migratory birds. Summer migratory birds simply say that birds that spend the winter in one place in spring and summer and another place in autumn and winter, such as geese, are typical summer migratory birds. Most of the cuckoos in China come from other countries and regions in late spring, and their purpose is simple: breeding.

In the fall, they flew away.

The reason is that the cuckoo will not feed its own children, and will eat its own mates, and will not show mercy when hunting, will throw the children off the cliff, and will leave the children alone for their own survival.

Because cuckoos can harm their own children. will give up their own children. They discard their own children when they are born. And will kill the children who don't like the eyes. Children who will give up on their disabilities.

Because it will putOwn eggsDown toIn the nest of other birds, do not hatch the birdie yourselfOther birdsGiveThey hatch, and give the eggs of the other birdsEatIt's cruel.

Cuckoo'sIntroduction

The cuckoo is a cuckoo in the classification of birds, and its call is similar to that of the cuckoo, and they will generally be seen in spring; They're lazy and bad, of course, they can't be blamed, after all, it's also their survival instinct, the only way to reproduce naturally, although it seems a little unacceptable, but who told them to survive like this all along? But it's also the basics of letting them live, and I personally think it's normal, after all, the same is true of the jungle.

Because of their ownCruelty is in natureInnateTarget.

Nowadays, we often look at cuckoos, they don't hatch their own birds, they are naturally lazy, and they don't make their own nests; Usually they lay their own eggs in a nest similar to them, and then spoil and eat other eggs; Let their eggs hatch well, because their eggs hatch cycle is relatively short, and then the birds will also damage other bird eggs after they grow up to prevent them from growing, in fact, they are really born with this characteristic, and there are no bird mothers to teach them; It should be said that they are not a little kind, this nature is also for reproduction and breeding, and it is really innate.

Actually, there is one more about the cuckooBeautiful legend too

In ancient times, there was the myth and legend of "Emperor Wang's Cry", Emperor Wangdi was said to be the county lord of a place in the last years of the Zhou Dynasty, and later gave way to retire, but the country died, and the soul was a bird after death, and the mouth bleed after the beginning of spring, which made people feel miserable; After that, it was called the spring of the valley bird, in fact, I don't know where to investigate the truth or falsehood, I personally think it's more miserable, after all, the people were finally forced to give way, but they didn't end up good, a little unacceptable.

Of course, I also hope that they will hurt other lives in the process of completing reproduction, after all, hurting life is really cruel in the eyes of others, and only mutual care will have a better picture.

Because they never build nests, they lay their eggs in the nests of other birds, and they do not hatch themselves, allowing other birds to hatch. Taking advantage of the absence of the other birds, they pushed out the other unhatched eggs, leaving only the first one to hatch.

Cuckoos are not "executioners", they do not attack other birds, they only feed on insects, so they are not cruel.

Because the cuckoo never builds his own nest, he will lay his own eggs in other birds' nests, and then push all the eggs out of other birds and fall to death.

1. The bird in front of the cloth grain is regarded as a spring bird, an auspicious bird, and a happy bird, and its call represents spring, hope, and happiness.

2. Because the cuckoo is calling, it is to urge farmers to hurry up and farm.

3. Inhabit open woodland, especially near water. Frequent morning chirping, 24-26 times per minute, continuous chirping for half an hour before stopping. Sexual cowardice, often lurking among the leaves. Usually only the sound of chirping is heard, and it is rarely seen.

4. Fly rapidly, follow a straight line, and before stopping, the pin beam often glides for a distance. Feeds on lepidopteran larvae, beetles, spiders, snails, etc. It eats a lot of food and plays a considerable role in eliminating pests.

The cuckoo is cruel because the adult bird has a habit of nesting at the expense of the offspring of other birds, and even the newly hatched cuckoo chick is the "executioner", which completely dashes the last hope of the host. The cuckoo lays its eggs in other people's nests almost without knowing it, and these hosts will successfully hatch and feed the cuckoo eggs as if they were their own eggs. In other words, the cuckoo "killed other people's children" and asked others to help them "raise children", which is not cruel.

However, the cuckoo's cruelty is not over.

The cuckoo does not build a nest all its life, and after the mating of male and female birds during the breeding season, it will tirelessly and persistently stare at other birds' nests, and when the owner flies out in search of food, it will quickly fly in. The purpose of eating one or more of the owner's eggs is to prevent the owner from finding something wrong with the number of eggs. In nature's environment where the jungle is the strong, the fittest survive.

The reason why the cuckoo is like this is that perhaps it is really bent over by "life" and has suffering. This is also the wisdom forced out to adapt to survival, which seems to be ruthless and cruel, but in fact it is a helpless move. This act of laying eggs in the nests of other birds is called nest parasitism or hatching egg parasitism.

It is the result of natural selection over a long period of evolution, a way to survive under environmental stress, and to ensure the survival and stability of populations in a way that can be minimized with minimal cost and investment.

There is no need to be hostile to one bird because of its way of living, after all, animals in nature have a complete ecosystem, in other words, the cuckoo also maintains the population balance of other birds to a certain extent. Natural selection for the survival of the fittest, any species that survives and reproduces in any way is successful from the perspective of the earth. Nature is actually very cruel, and opportunistic behavior such as cuckoos is actually beneficial to the development and reproduction of their population.

The cuckoo is both familiar and unfamiliar to everyone, because we often hear its call. Whether the cuckoo is cruel or not depends on the point of view of the problem, it feeds on insects and does not attack other birds. However, the cuckoo will use the nests of other birds to lay its own eggs in other nests, so it is said that this behavior is cruel to the mother who lays the eggs.

Why are cuckoos "cruel"? The cuckoo is a selfish and self-serving characteristic, and it also has anti-bird behavior, laying its eggs in the nests of other birds for others to hatch and feed its offspring

Cuckoos are a common bird, especially in rural and mountainous areas, where they can often be heard calling hoarsely. So why do cuckoos keep calling?

Physiological needs. First, the frequency and volume of cuckoo calls change with their age and sex. During the breeding season, males make high-frequency calls to attract females.

In addition, the call helps the birds to determine their territory to hold back hail and prevent other birds from invading.

Behavioral habits. However, not all cuckoos will be non-stop. Many young cuckoos mimic the calls of other birds, while older birds learn to control their calls and only make calls when necessary.

Express yourself. At the same time, cuckoo calls are also a way for them to express themselves blindly. Through their calls, they are able to convey their messages and emotions. For example, when they are frightened or upset, they will keep calling in an attempt to get the attention of other birds in search of protection.

Find a partner. In addition, the cuckoo socks are also a monogamous bird, and the male will keep calling in order to attract the attention of the female. Females use the volume and frequency of their voices to determine the male's health and reproductive ability, and then choose their mates.

Summary. To sum up, the reasons for cuckoo calls include physiological needs, behavioral habits, self-expression, and finding a mate. While each cuckoo's call is different, their calls are a wonderful part of nature's world.
