In ancient times, there was a very common nickname between lovers, which was "Yuanyang". Yuanyang is a kind of bird that often lives in water. Married mandarin ducks often accompany each other and sleep around their necks. Its intimate modality is really like a loving couple in the world. Because Yuanyang is always hermaphrodite, the ancients called Yuanyang a "horse bird", which means a matching bird.
It is precisely for this reason that people regard the word "Yuanyang" as the nickname of lovers, and sincerely hope that all couples in the world can be as happy as Yuanyang, grow old together and love each other for life. Moreover, "Yuanyang", an elegant name for husband and wife, is widely spread among the people, almost to the point where women and children know it.
Extended data:
Current situation of mandarin duck population:
The species has a wide distribution range, which is not close to the critical value standard for the survival of vulnerable and endangered species (the distribution area or fluctuation range is less than 20,000 square kilometers, and the habitat quality, population size and distribution area are fragmented), and the population trend is stable, so it is evaluated as a species without survival crisis.
Yuanyang is also one of the traditional export birds in China, which once had a large population in China. Every year, a large number of live birds are hunted, supplied to domestic zoos and exported. Before 1975, 40-50 sheep were often encountered in Changbai Mountain in spring and wintering land in the south in winter, but this spectacular sight was hard to see. The main reason is that the population has decreased due to deforestation and hunting. According to the survey, the breeding population in China is 1500-2000 pairs. Has been included in the world endangered bird list.
