Although black swans and white swans are both swans, they are not the same species, so they do not have too close frolicking behavior together. Unless there is the interference of human factors, there will be a situation where white swans and black swans are together, which is not a normal occurrence in the natural state.
-
Just as polar bears are unlikely to be in the same frame as penguins, black swans that are only in Australia and New Zealand are unlikely to be among them.
-
Black and white, both pure and free of impurities, maybe in the eyes of the black and white swan, the other party is "the sand in the eyes" is very annoying, there is no reason to like it.
Swans have a habit of cleanliness and are "appearance associations".
Same as above, black and white are the purest and purest colors, and in the eyes of black and white swans, the other party's color may be "stains". The animal kingdom chooses mates based on appearance, and being beautiful, dancing, building a beautiful house, etc., are all plus points - "If the appearance is not good, you can't talk about anything".
Things gather like geese in groups".
It is easier to get together if there is something in common, the difference between black and white is too great, even if the appearance is similar, but the color is like a chasm, like the Jingwei River, each playing its own game.
There are rules on the ancestor of the swan.
Maybe the swan ancestor set a rule: black swans and white swans can't socialize. Therefore, in order to continue to stay in the community, we should not play with each other in a friendly manner. Alas......

Why the black swan.
Not frolicking with white swans?
Black swans and white swans are somewhat similar in appearance, both are creatures of the genus Swan in the duck family, but they are not the same species, and under normal circumstances, even if they live together, they will not get too close.
This is not absolute. With outside interference or individual differences, you can see black and white swans swimming, flying, frolicking, and even mating together. From 2014 to 2016, a long-term stable relationship between white swans and black swans was found in Jiangxi, China.
Black swans and white swans are often recorded together abroad.
Black swans and white swans often do not produce fertile offspring under natural conditions (eggs cannot be fertilized), but hybrids have been created through human efforts.
White swan, scientific name whooper swan.
It is a globally vulnerable species and a national second-class protected animal.
The white swan is covered with white feathers, and when swimming in the water, it often stretches its neck and body at a slight right angle, with a leisurely and complacent demeanor, which looks beautiful.
White swans are migratory birds, and they often stay in the reeds.
In many lakes, land, water and ponds, swans have a docile temperament, like to move in groups, often stay on the water, and can fly and walk on the ground. Swans do not have a fixed home, and they are generally not fixed in one place except during the breeding season. When swans sleep, they sleep with their necks bent and their heads tucked into their wings, drifting with the waves.
In addition to the white swan, there is also a species of black swan, which grows in Australia and is mainly active in the eastern region.
Like the southern regions, black swans are similar in size to white swans, they are better at flying, and both white swans and black swans like to eat some plants and rhizomes commonly found in the water, as well as floating insects and various algae.
-
It may be that the two species of swans are different, so they will not be the same type. Of course, I'm just guessing, because after all, they are different colors, and they are also animals, they have sight and perception.
-
White swans do not eat or sleep after the death of their partners, while black swans find another mate, so it is more difficult for white swans to have offspring than black swans. The white swan is a globally vulnerable species, and the black swan is not concern.
The black swan is a precious species in the swan family, because its feathers are black, so it is called the black swan. People have the impression that the scarf swan is a symbol of beauty, nobility and peace. In addition to the difference in feather color, black swans and white swans also have differences in living habits.
It is difficult for a white swan to choose a mate, whereas it is easy for a black swan to choose a mate. A black swan will be married to another black swan immediately after being widowed, and if you think about it from the perspective of reproduction, it is not too much to continue widowhood. Because only in this way can its reproduction rate be guaranteed.
-
Things are gathered by like, and people are grouped. "It's not the same species, it's hard to coexist peacefully, and most different animals can't live together.
Black swans are not the same animal as white swans, so they don't frolic together.
-
It can be paired, and black and white swans have been observed at home and abroad Under external interference or individual differences, you can see black swans and white swans swimming, flying, frolicking and even mating together.
-
Although the colors of the two of them are different, neither of them has a different disease, and it is not that they will not play together, but people may see the difference between white and black.
-
Because the black swan and the white swan are somewhat similar in appearance, they are both animals of the genus Swan in the duck family, but they are not the same species, and under normal circumstances, even if they live together, they will not be too close.
-
I think they may also be racist, or even though they are all called geese, they may also have a certain distinction and a kind of distance.
-
Black swans and white swans are different species and do not frolic together, but also fight each other.
-
Look down on each other! Though it is said to be the same kind. It's too big.
-
Those who are not in a group will certainly not frolic together.

1. The color of the feathers is different
Black swan. It is a precious species in the swan family, because its feathers are mainly black, so it is called black swan, white swan.
The feathers are predominantly white.
2. The situation of mate selection is different
It is difficult for a white swan to choose a mate, whereas it is easy for a black swan to choose a mate. Immediately after being widowed, the black swan will combine with another black swan, and the black swan will breed in spring and autumn throughout the year. A pair of black swans can breed 40 to 50 goslings a year, so widows need to be re-searched to ensure that the reproduction rate of black swans is not affected.
3. Different hatching rates:
The biggest feature of black swans is that the hatching rate and the survival rate of goslings are extremely high, compared to the hatching rate of white swans and the survival rate of goslings.
Swans mainly feed on the roots, stems, leaves, and seeds of aquatic plants, as well as mollusks, insects, and earthworms.
If you look at the swan purely from the shape of the swan, the average person will prefer the white swan, because the swan is a symbol of beauty, nobility and peace. However, black swans are relatively rare and mainly distributed in Australia.
and so on, so it is more precious.

The swan and the white goose used to be a family, and they toiled for food every day, and the white goose complained, "I wish I could find a place with abundant food, I don't want to be tired of it." ”
The swan said, "As long as we work hard, we will find food, and we have the ability to fly in the sky, how blessed we are!" ”
At this time, a man came to the swan and the white goose and said, "I have a lot of food in my house, and if you are willing to come to my house to live, I will give you a lot." Food. ”
"No," said the swan, "I wish I could find the Sail Rock by my own ability, or at least then I would be free." ”
At this time, the white goose was silent, and it said, "I am willing to go to the human home to live, so that I can have no worries about food and clothing." ”
The white goose and the swan chose a different life, the white goose got rich food from humans, gradually got used to this lazy life, lost the ability to fly, lost freedom, and became a poultry.
The swan, on the other hand, became the noblest animal, living freely in the sky.

Because they are all swans.
The white swan, also known as the whooper swan, people have seen through the white swan, and also prefer the white swan, comparing the white swan to the "angel", "the bird of the heavenly palace", and the bird of good luck". In the mighty white swan community, there are also a few black swans, people regard the black swans as "alternative", in fact, the black swans are quite beautiful, black feathers, shining bright, only the abdomen, the edge of the wings have very few white feathers, fiery eyes and nose, aggressive.
The appearance of black swans, people found that they came from Ukraine, and the black swans also have a certain legendary and mysterious color. In life, people have a great deviation from what they encounter about a certain major event, and the events that they look away often become "black swan events". Black swan events have several characteristics:
accidentality; significant impact; In hindsight, people think it's more or less explainable and sexual.

It is difficult for a white swan to choose a mate, whereas it is easy for a black swan to choose a mate. The feather color will vary.
One. Basic concepts.
Swan refers to the bird of the genus Cygnus (scientific name: cygnus), a total of 7 species, belonging to the genus of migratory birds. It is found on all continents except Africa and Antarctica.
It is the largest group of individuals in the duck family. It prefers to live in groups in lakes and swamps, and feeds mainly on aquatic plants, but also eats snails and mollusks. Most are monogamous and accompany each other for life.
Two. Exterior features.
1.White Swan Species: White Swan:
Ornithischia, duck family, tall (155 cm). The mouth is red, and the base of the mouth has a large yellow patch. The yellow extends to the lateral margin of the upper beak in a pointed shape.
When swimming, the neck is straighter than that of mute swans. The plumage of sub-adults is more monotonous than that of mute swans, and the mouth color is also light. Much larger than a baby swan.
iris – brown; Mouth - black with yellow base; Feet – black. Calls: The call is a distinctive klo-klo-klo sound when flying, but the contact call is like a loud and melancholy horn sound!
Very smart.
2.Swans are large birds, the largest in length, weighing more than 6,000 grams. Whooper swans, also known as white swans and hoofs, are large migratory birds with a body length of about 10kg and a weight of more than 10kg.
The plumage is white, the beak is mostly black, and the upper beak to the nostrils are yellow. They have a long head and neck, accounting for about half of their body length, and often swim with their necks straight and their wings close together.
3.Adult swans can weigh up to 30 pounds, and when provoked, they are very aggressive and will not hesitate to attack. If an enemy it encounters is non-swimmer, the swan will pull the enemy into the water and drown it.
Three. Habits.
Swans maintain a rare "lifelong partnership". During the wintering in the south, they are fed or rested in pairs. While the female swan lays her eggs, the male swan is on guard.
When it encounters an enemy, it flapps its wings and steps forward to meet the enemy, bravely fighting the opponent. Not only do they help each other during the breeding season, but they also usually work in pairs, and if one dies, the other can indeed "keep the festival" for it and live alone for the rest of their lives.
