There are double toes on the front and back of the sole. The beak is stout and powerful, and it bends down a little. Fly quickly and quietly. Four-tone cuckoo can hear its loud and somewhat bleak cry almost day and night before and after the ear seeds. The characteristic of the cry is four tones-"Cut the wheat quickly! Cut the wheat quickly! " "Quick broadcast valley! Hurry and sow the valley! " . Cuckoo's calls are "Cuckoo" and "Cuckoo".

Edit the living habits of this paragraph.

Parasitism in brooding is a special reproductive behavior. Birds lay eggs in other birds' nests, and their parents hatch and brood on their behalf. The meadow pipit in the photo feeds on rhododendron and belongs to the parasitic type of interspecific larvae. Rhododendron is the most representative of more than 80 species of birds. Can parasitize 125 eggs in other birds' nests

The parasitic behavior of larvae is as follows: the choice of host, the search for rhododendron in breeding period is similar to that in incubation period and brooding period, and the feeding habits of chicks are basically the same.

cuckoo

Similarly, the hosts that are oval and easy to imitate are mostly passerine birds. During the parasitic time, rhododendron lays eggs quickly before the host begins to hatch and when the host leaves the nest. In late spring and early summer, they fly north. It doesn't build its own nest or hatch its own eggs. It lays an average of 2- 10 eggs a year, but it puts the eggs in the nests of thrush and reeds and lets these birds hatch them carefully for themselves. And every time it flies to the nest, it only gives birth to one.

The co-evolution of larval parasitism is manifested in the morphological characteristics of host eggs. There is no obvious difference in the color and size of parasite eggs. At the same time, the host's ambiguity in distinguishing eggs is also one aspect. Have an effect on the reproduction of the host. Rhododendron usually removes an egg from the host before laying eggs, or pushes it out of the nest, forcing the host to lay eggs again. However, once the brood-parasitic chicks hatch, it has the habit of pushing the chicks out of the nest, thus enjoying the parental rearing alone, which will reduce the success rate of host reproduction.

One legend is that ...

The legendary cuckoo crying blood should be a cuckoo with four tones, commonly known as cuckoo. Because of careful study, the oral epithelium and tongue of rhododendron are red, which the ancients mistakenly thought was full of blood. When cuckoo sings, it is the time when azaleas are in full bloom, so there is a saying that the color of azaleas is dyed with blood by cuckoo's cry: "What are the merits of azaleas and birds?" It is suspected that the blood in the mouth drips into the flowers on the branches. "("Complete Tang Poetry "Volume 759" Rhododendron "sentence)" Rhododendron sends rhododendron, like blood like Zhu. It should be that I can't stay in spring, and the night wind is cold. " (Qiu Jin)

According to Li Shizhen, "Rhododendron was born in Sichuan, and it is also found in the south today. It is dressed like a sparrow hawk, but its color is miserable and black, and there is a small crown on its red mouth. At dusk in spring, people will crow. When they crow at night, they will sing to the north, especially in Zhixia, where the sound is sad day and night. Tian Jia and others use it to promote agriculture. But insect-eating moths can't live in their nests and hide in the winter months. "

The story of "Wang Chunxin's cuckoo crying" is widely circulated among the people. It is said that there was a man named Du Yu in ancient Shu who became an emperor and became a cuckoo after his death. The name of the cuckoo probably comes from this.

Cai Xiang's poem in the Song Dynasty said: "The rain is full of plows, and those who know how to promote agriculture are not savages. It's early spring, and it's time to put on your coat and melt your calves. " Lu You also wrote a poem: "The season is too clear, cuckoos sing in the morning, spring comes to drive, the country is cultivated, the red and purple flowers are exhausted, and the green and yellow wheat ears are full." It doesn't make sense from now on. You can listen to the strings. "The cuckoo in the poem. Cuckoo Zhu Zhen, a poet in the Southern Song Dynasty, really said, "The cuckoo cries for spring return, but the blood remains after kissing goodbye." It also fully embodies the spirit of Du Fu crying earnestly and responsibly to urge people to "spread grain widely".

In Europe, the cuckoo's cry means the arrival of spring, because cuckoos spend the winter in Africa every year and return when the climate in Europe warms up in March. After mating, the female cuckoo is ready to lay eggs, but she can't build her own nest.

It will come to the nest of smaller birds, such as robins and songbirds, take the original egg and replace it with its own. Compared with its size, its eggs are very small, and the markings on the eggs are very similar to those of other birds, so it is not easy to be distinguished. If not, its eggs will definitely be thrown out.

Top Ten bad mother in Animal Kingdom: Cuckoo.

The cuckoo's eggs hatch earlier than other birds. When the young bird comes out, it will immediately throw other eggs out of the nest. It does this because it will soon grow very big and need to eat all the food that the foster mother can find.

Cuckoo flies back to Europe in spring, stops on a stake, a branch or a wire, and calls for its mate. Cuckoo is named after its sound: an easily recognizable "cuckoo" sound.

A little cuckoo is being fed by its foster mother, who is a much smaller warbler. The food it needs is equivalent to the total amount of food that 3-4 young birds born to their adoptive mothers need to eat.

Cuckoo birds lay eggs in their nests when other birds are not looking. It must be finished soon. Its eggs have a particularly thick shell so that they won't break when they fall into the nest.

symbolic meaning

In ancient mythology, Du Yu, the king of Shu, was forced to give way to courtiers and live in seclusion in the mountains.

Cuckoo (16)

After death, the soul becomes a cuckoo. Therefore, the cuckoo in ancient poetry has become a symbol of desolation and sadness. Li Bai's "I heard that Wang Changling moved to the left, and Long Biaoyao had this letter": "Huayang fell to the ground and Wendao Longdu crossed five streams. I am worried about the bright moon, and I will follow the wind to Yelangxi. " The cuckoo is a kind of bird. The first sentence is the scene of eyes, which conveys the feeling of parting and sadness in the bleak natural scenery. Three or four sentences express infinite nostalgia and deep sympathy for friends with the rich imagination of caring for the bright moon. He Zhu, a poet of the Song Dynasty, wrote "Remembering Qin E": "In the middle of the night, pear blossoms and snow just fell in the atrium; Pear blossoms are overwhelming, and azaleas cry blood. " In the middle of the night, the moonlight shines on the snow-white pear flowers in the courtyard, and the cuckoo is mourning, which makes people miss their loved ones more and feel sad. Poets express their deep homesickness by describing sad scenery. Others, such as "the lonely pavilion is cold in spring, the cuckoo sounds in the sunset" (Walking on the sand), "Zi Gui still cries blood in the middle of the night, but he can't call it back if he doesn't believe in the east wind" (Ling's "Sending Spring"), all express his sadness or homesickness with the cuckoo's wailing.

Forest Man

Every time spring comes to Wuyishan, birds can be heard everywhere, as if urging people not to miss the farming season and sow in spring as soon as possible. This is the mysterious cuckoo singing. There are many magical legends about rhododendrons. Throughout the ages, many literati have written poems for them. In spring and summer, the four-tone cuckoo will crow all night. Its plaintive cries often arouse people's various feelings. In addition, the oral epithelium and tongue of cuckoo are all red, and the ancients mistakenly thought that it was full of blood, so many legends and poems about "cuckoo weeping blood" and "weeping blood deeply" were produced. Rhododendron is a typical bird. It doesn't build nests, hatch eggs or feed young birds. These tasks are all done by the adoptive parents of Xiao Du Fu. There are many interesting secrets about these. First of all, how can cuckoos parasitize eggs from other nests without being found? At the turn of spring and summer, female cuckoos will carefully look for the nests of birds such as thrush and reed warbler before laying eggs. After the target is selected, she will make full use of the similar characteristics of herself and the harrier in appearance, size and body color and fly long distances. The flying posture of cuckoo is also very similar to that of raptor rock harrier; Fly very low, turn sharply to the left and right. Occasionally flap your wings loudly to scare the brooding birds. When the hatching bird saw the figure of the bird of prey flying at low altitude, it was scared to abandon its home and flee for life, and the cuckoo achieved the purpose of intimidation. How does a cuckoo throw its eggs into someone else's nest? Some lay eggs directly, but for nests that are too small or difficult to enter, they will lay eggs first, and then carefully put the eggs among the eggs of other birds with their beaks. But before putting their own eggs, cuckoos often take someone else's eggs from their nests (eat them or throw them away). The cuckoo is much bigger than some birds, but the eggs it lays are very small. In addition, the cuckoo's eggs are strikingly similar to the nest owner in shape and color (the result of natural selection), so it is possible to confuse the truth with the truth, which is difficult for other birds to distinguish. Although the cuckoo's eggs are small, they develop rapidly and often hatch earlier or at the same time as the nest owner's eggs. When the baby cuckoo was born, she was busy as a porter: carrying another bird (or bird's egg), supported by immature wings, she climbed carefully to the nest. He lowered his head, put his forehead on the bottom of the nest, suddenly leaned back, lifted the chick (or bird's egg) on his "shoulder" and dug it out of the nest. Then the little "porter" slipped to the bottom of the nest and got under another victim to continue his handling work. A few hours after hatching, the little cuckoo has a desire to get rid of everything in the nest. When the foster mother came back, she saw that there was only one chick left in the nest, so she loved the murderer as a pet and fed the little cuckoo more carefully. Little cuckoo plopped, left without saying goodbye and flew away. Although cuckoo has a bad habit of brooding, it is a famous bird that loves the enemy of pine trees, Dendrolimus punctatus. Dendrolimus punctatus is a pest that many birds don't like to eat, but Rhododendron prefers its delicacy. It is observed that a cuckoo can prey on 100 caterpillars every hour. In addition, azaleas also eat other agricultural and forestry pests, so people also call them "forest guards".
