For humans, monogamy is a legal and moral constraint, but there are a few countries that also allow polygamy, but rarely see the phenomenon of polyandry, and even if there are cases that are extremely rare, but in the animal kingdom, there is neither law nor morality, those "monogamous" animals, if one party dies, what will happen to the other party?
Is the Mandarin duck, a symbol of love, really so dedicated?
Literati inkers have always been stingy about the waterfowl of the Mandarin Duck, and the Mandarin Duck is a symbol of loyal and indomitable love, so there will be a classic Yellow Plum drama paragraph of "Only Envy the Mandarin Duck and Not Envy the Immortal" in "Heavenly Immortals", but today we want to talk about the Mandarin Duck, which may surprise you!
Mandarin ducks just show their affection during the breeding season
Mandarin refers to male birds, ducks are female birds, and generally the Mandarin ducks we see are paired and inseparable. Mandarin ducks are colorful, and playing in the water is the focus of the scene, so the poems of the poet Li Bai will mention the Mandarin duck many times, such as "Seventy Purple Mandarin Ducks, Double Double Drama Garden", "Willing to Meet the Same Heart, Fly as a Purple Mandarin Duck", etc., but I am sorry, Comrade Li Bai and all the friends who sing praises for the Mandarin Duck have been deceived!
Mandarin ducks are "married" and will cheat repeatedly even during the breeding period when monogamous show affection! Mandarin ducks are mainly "matriarchal social system", because Mandarin ducks are migratory birds, generally travel from south to north in migration, their breeding season is in the warm season from April to September, each breeding season, the female birds are the ducks will re-select the mandarin, and the male birds have a lot of competitors!
If you like it, then this family affair will become, and this breeding season will basically be these two pairs! But in the next breeding season is not necessarily, of course, the male bird can also come back to find the female bird, but it is only a candidate, and the female bird duck never misses the old love, just from the perspective of bright coat color and health and might, of course, we do not know the standard of the duck, but the animal mate selection is generally like this.
Also, the male bird duck is basically a ruthless species of "pulling NIAO to go", after mating egg laying nest and raising offspring, that is the female bird duck thing, think about this nest has about 7-12 eggs, incubation period of about a month can imagine what the female bird experienced during this period! In addition, I have also done a test, after the Mandarin Duck "beats the Mandarin Duck scattered", they are actually looking for a new joy, this is not a typical scumbag scumbag!

So the next time you use the Mandarin duck metaphor for love, that is, bury people!
<h1 class="pgc-h-arrow-right" > what other animals are there? </h1>
7 gourd babies are all capable of each other, according to genetic point of view, these 7 gourd babies have at least 7 fathers, you see, even the mythological stories are unreliable, animal chaos is actually very common!
Chimpanzees most similar to humans are polygamous, and the male chimpanzees have a great desire for power, which means not only the leader of the orangutan community, but also the power to mate with more female orangutans! Female orangutans ,on the other hand, "sell" themselves for food or other needs, and this exchange is so similar to the phenomenon in human society!
And bonobos are more exaggerated than chimpanzees, if chimpanzees are still polygamous, then bonobos are QUN-intercourse, LUAN-intercourse, and even bonobos have same-sex behavior and KOU-X behavior between bonobos, and bonobos are also the same as humans, mating behavior has nothing to do with estrus, and also turns mating behavior into a social tool, so evolutionary biologists have proposed that the evolution of bonobos is closest to humans!
For example, of the 35% of mammals surveyed by zoologists, only 9% of about 226 species are social monogamous, of course, this social monogamy is to live together, raise cubs, on the surface it seems to be monogamous, but in fact they are chaotic, that is, they are all secretive!
What about birds and birds? On August 4, 2016, a very interesting paper was published in the journal Molecular Ecology entitled "A comparative assessment of SNP and microsatellite markers for assigning parentage in a socially monogamous bird" (A comparative study of the SNP and MSI markers of monogamous birds used for paternity testing), the case study is a common monogamous songbird black-throated blue warbler, and the findings are a bit overwhelming!
Only about 92% of the small birds hatched by the black-throated blue warbler are male birds, and 8% do not know where they come from, which means that the black-throated blue warblers who are together every day, the female birds do not know when to sneak out and fool around with other male birds, while the male birds pay for the waywardness of the female birds as wronged heads, and raise this little bird of unknown origin together!
Black-throated blue warbler
But what's even more frightening is that except for human DNA identification technology, male birds will never know this result! Dear male compatriots, do you want to play very energetic, ah, look at more Ha!
< h1 class= "pgc-h-arrow-right" > whether there are animals that are loyal to love</h1>
In fact, even the monogamous model of swans and eagles will occasionally cheat, but just above we mentioned that social monogamous mammals, in addition to most of them "chaotic", there are still several animals that seem to be relatively harmonious, they are California deer rats, Koch's canine antelope, coyotes and Falkland hamsters!
We are not familiar with several other animals, but is it a bit beyond everyone's expectations that a very cunning animal like a coyote is actually loyal and monogamous? Of course, we have to explain that they are only temporarily not caught by zoologists to mess with the evidence, not a lot of cases of cheating are done by those "honest men", so ah, do you want to lose faith in love?
Of course, don't worry, we will list two absolutely lifelong animals
The first is the anglerfish (squid)
The digestive system of the male squid loses its function in adulthood, it must be attached to the female squid and gradually merge with the blood vessels of the female squid's body, and other parts except the sperm nest will gradually disappear, becoming a "hermaphrodite" reproductive organ on the female squid! So the sturgeon is determined to be made for life, because there is no way to replace it, but the female sturgeon can be parasitized by multiple male sturgeon, is it not to make your dream shattered from the beginning to the end?
The second, the creature that really ends up in one place: the two-body worm
This is a true double body worm parasitizing the gills of the carp, it looks like a butterfly, this is two true double worms overlapping, a single worm will look for the other half in the gills of the carp, they are actually hermaphrodites, even if there is no other half, they can self-fertilize and lay eggs, but if they do not find the other half, they can not mature, is it a dead cycle?
Therefore, once the true two-body insects encounter each other, they will directly paste it, and simply qingqing me and me, after all, the "fish sea is vast", it is not easy to find the other half, after fitting, the reproductive organs of the two true double-body insects will grow together, and they can no longer be separated, if you want to forcibly separate, then the reproductive organs of the two cannot be saved!
In fact, in the animal kingdom to pursue monogamy is contrary to the theory of evolution, after all, betting on an object, for the continuation of the great task of offspring, the risk is too great, in order to ensure the superior genes of offspring, is not it normal to find a few more?
