Cuckoo is the common name for birds in the family Rhododendronidae, mainly the great cuckoo, three-voiced cuckoo and four-voiced cuckoo. One-third of all cuckoos have nest parasitism. It belongs to the forestry beneficial birds. There are many poems and songs about the cuckoo, and the most typical allusion is the story of Wangdi turning into a cuckoo.

The big cuckoo's call sounds like "Bugu, Bugu", so it is also called Bugu bird; the three-sound cuckoo's call sounds like "Miguiyang", so some places call it Miguiyang; the four-sound cuckoo is also known as Ziguibird's call sounds like "Cutting wheat quickly", "Cutting wheat", "Cutting wheat", "Cutting wheat", "Cutting wheat", "Cutting wheat", "Cutting wheat", "Cutting wheat". "The cuckoo feeds on insects. The cuckoo feeds on insects and is a famous forest bird. Such as pine caterpillars, poisonous moths and other birds do not dare to eat, but for the cuckoo is a delicious meal. Most of them live in the woods in tropical and temperate regions. About two-thirds of all cuckoos, including all North American species, nest and raise their young; only about one-third raise their young parasitically. Nest parasitism is a specialized reproductive behavior in which birds lay eggs in the nests of other birds, which are incubated and fledged by the parent. The photo of a grassland treecreeper (Anthus pratensis) feeding on a Great Cuckoo is an example of interspecific nest parasitism. The great cuckoo is one of the most typical nest parasites among the more than 80 species of birds, and it can parasitize eggs in the nests of 125 other species of birds. The nest parasitism behavior is manifested in the following aspects: host selection, in the breeding period, the great cuckoo seeks for hosts that are similar to those in the incubation and brood-rearing periods, with basically the same dietary habits of the chicks, and with easy-to-mimic ovality and coloration, which are mostly finch-like birds. In terms of parasitization time, the great cuckoos often lay their eggs before the hosts start to hatch, and then quickly parasitize and lay their eggs when the hosts leave the nest. In late spring and early summer, it flies northward. It will not make its own nest, nor incubate eggs, an average of 2-10 eggs per year, but the eggs laid in the nest of the paintbrush, reed grossularia, so that these birds for their own careful incubation. And it only lays one egg in each nest it flies to. The synergistic evolution of nest parasitism is manifested in the morphological characteristics of the host eggs. The host's eggs do not differ in color or size. The host's ambiguity in recognizing the eggs is also a factor. In terms of reproductive impacts on the host, C. grandis often removes one or all of the host's eggs from the nest before laying, forcing the host to re-lay the eggs. Once the nestlings hatch out, the cuckoo pushes the chicks of the host parent out of the nest, thus enjoying the nurturing of the host parent, which reduces the success rate of reproduction of the host. Allusion Liu Kezhuang of the Song Dynasty wrote the lyrics of "Memory of Qin'e": "...... The Du Yu on the branch cries blood, and the willows on the street blow into snow. Blown into snow, light smoke and sparse rain, March in Jiangnan." The lyric refers to a mythological story: at the end of the Zhou Dynasty, Du Yu, the king of Shu, claimed the title of emperor and was called Emperor Wang. At that time, there was a man who came back from the dead, Tie Ling, who became the prime minister. At that time, the people were suffering from floods, so Bailing chiseled the Wushan Mountain and opened the Three Gorges to eliminate the floods. Seeing his great achievements, Emperor Wangdi gave the throne to him, and he himself lived in seclusion in the western mountains. Duyu paid attention to teaching people farming during his life, after his death, he still did not change his nature, he turned into a bird (i.e., cuckoo bird, also known as cuckoo bird), every spring, always call people "cuckoo", "fast cuckoo" to remind people to plant seeds in time. At this time, it is when the azalea is open, the ancients see a cuckoo on the mouth has a red spot, that it is a bitter cry and outflow of blood, so there is "all the blood of the birds stained e", commonly known as the azalea. Ancient poets often guanxin azalea. For example, "azalea flowers and birds, the grievances of the two how to credit; all the blood in the mouth, dripping into the flowers on the branch" (Cheng Yanxiong); "Yeye re brilliant, flowers in the unparalleled party", "the flowers of this thing is Xishi, hibiscus and peony are all ugly woman " (Bai Juyi). Legend has it that the cuckoo bird crying blood should be the cuckoo bird commonly known as cuckoo with four voices. Because of the red color of the cuckoo's oral epithelium and tongue, the ancients mistakenly thought that the cuckoo cried blood from its mouth. When the azalea sings, it is the time when the azalea flowers are in full bloom, so there is also the azalea flower color is the azalea bird crying blood dyed saying: "azalea flowers and birds, the complaint of the two how to credit. It is suspected that it is blood from the mouth that drips into flowers on the branches." (Full Tang Poetry, Vol. 759, Cheng Yanxiong, "Azalea Flower") "The azalea flower cries, like blood like vermilion. It should be that it is unable to stay in spring, and the wind and dew in the depths of the night are also cold and miserable." (Qiu Jin) According to Li Shizhen, "The azalea comes out of Shu, now also in the south, like a sparrow harrier, but the color is black, red mouth with a small crown. Spring twilight is crowing, night crowing up to the day, the song will be to the north, to the summer, especially, more than day and night, its voice mournful. The farmers are waiting for it to develop their farming business. But eating insects and worms, can not be a nest, living in other nests to give birth to children, the winter months are hidden hibernation." Song Dynasty's Cai Xiang poem: "Bugu sound rain full of plow, urging plowing is not the only wild people know. Hoe do not say spring plowing early, it is the time to wear a straw raincoat calf." Lu You also said in a poem: "The season is over the Qingming, the Bugu song, but the spring urge to drive, that for the country to urge plowing, red and purple flowers and branches, green and yellow wheat ears into. From now on, there is no need to listen to the sound of the Shun string." In the poem, the cuckoo bird urges plowing. That is, the cuckoo bird. Zhu Xizhen, a lyricist of the Southern Song Dynasty, wrote, "The cuckoo calls for the return of spring, and the blood-crying by the kiss is still there." More fully reflect the cuckoo for urging people to "cuckoo" and cried dry mouth and tongue, lips cracked blood, serious and responsible spirit cuckoo bird cries blood in spring and summer, the cuckoo bird will be all night non-stop cawing, it's that bleak and mournful sad cawing, often provoke people's many feelings, coupled with the cuckoo's oral epithelium and tongue are red, the ancient Chinese saying that the cuckoo's mouth and tongue are red, and the cuckoo's mouth and tongue are red. And the tongue is red, the ancients mistakenly thought that it "crow" full of blood, thus leading to many legends and poems about "cuckoo cries blood", "cries blood deep resentment".
