First, the mysterious appearance of the black swan
Black swan, a remarkable creature, always appears with mysterious color. In people's minds, the black swan symbolizes night, loneliness and mystery. Different from the pure and happy white swan, the black swan is not naive, but has a lonely and arrogant artistic conception. Many lonely but proud people like black swan, perhaps attracted by this unique temperament.
The mystery of the black swan is that it was not known to westerners at first. In their cognition, it was once thought that only the white swan existed. However, when the first black swan appeared, this cognition was completely subverted. Compared with the white swan, the black swan is more mysterious because it is rare.
Black swan is a kind of large-scale swimming bird of the genus Cygnus, which has a typical swan appearance. Compared with its own size, the black swan has the longest neck among swan species. Their feathers are pure black and shiny, as if they can devour all the light around them, but they inadvertently reveal a bit of blue-green luster, like the stars in the deep universe, which makes people daydream. The black swan's eyes are deep and smart, as if hiding endless stories and wisdom, which makes people unforgettable at a glance.
The beauty of the black swan is a mysterious and profound existence. It is not only an interpretation of color, but also a unique landscape in nature. The figure that glides gently across the lake, like the messenger of the night, is elegant and solemn, and every time it spreads its wings, it exudes indescribable charm. When swimming in the water, they show a distinctive elegance, and every movement is so leisurely, as if time slows down for them. And when they soar, it is a touching picture, and the perfect combination of strength and beauty makes people feel awe.
The beauty of the black swan is a shock in silence, an elegance in mystery and a precious gift given to us by nature. They not only beautify the world, but also remind us how important and rare it is to remain unique and pure in the midst of complexity. The beauty of the black swan is a shock beyond vision and a profound interpretation of the depth and breadth of life. In a unique way, it quietly tells the extraordinary life and the mystery of the universe, and invites every soul to feel, fear and love.
Second, the morphological characteristics of the black swan
1. Unique appearance
Black swan is a large-scale swimming bird, with a body length of 110-140 cm, a weight of 3.7-8.75 kg and a wingspan of 160-200 cm. It has the longest neck of the swan species, usually arched or upright in an "S" shape. The whole body feathers are curly, mainly dark black, and the abdominal feathers are gray-white, and white flying feathers can be seen when the wings are opened. The tail is long and forked, and the outer feather tip is blunt and upturned like a harp. It has a bright waxy beak, red or orange, and a white stripe near the end. Iris is red or white, tarsal and webbed are black.
2. Noble temperament
The appearance of black swan shows noble temperament everywhere. First of all, its slender neck is in an elegant "S" shape, like a noble dancer, ready to show graceful dancing at any time. Feathers curled all over the body, with dark gray or dark brown color, shine mysteriously in the sun, which is both solemn and restrained. The gray-white feathers in the abdomen are in sharp contrast with the black main feathers, adding a sense of hierarchy. The white flight feathers are particularly eye-catching when spreading their wings, just like the bright colors dotted in a beautiful picture.
The noble temperament of the black swan is also reflected in its posture. Whether swimming in the water or walking on land, the black swan always maintains an elegant and calm posture. In the water, it paddles its feet gently, and its slender neck bends slightly, as if it were meditating and enjoying the beautiful scenery around it. When flying, the black swans are arranged in a word line or a "V" shape, their wings are flapping slowly, and sometimes they whistle, which is like a king in the air, majestic and noble.
The curly feathers of the black swan add a unique charm to it. These feathers are closely attached to the body, which not only shows the health and vitality of the black swan, but also makes people feel a kind of exquisiteness and delicacy. When the black swan combs its feathers, it will gently arrange each feather with its red beak, with gentle and elegant movements, as if it were carrying out a sacred ceremony.
In a word, the black swan has become a remarkable landscape in nature with its unique appearance and noble temperament. Its existence makes people feel the magic and beauty of nature, and also makes people have a deeper understanding of nobility and elegance.
Third, the habits of black swans
1. Habitat
Black swans like to live in shallow waters, coniferous forests, lakes, ponds and other places. They have high requirements for water environment, and usually choose areas with good water quality and overgrown aquatic plants. For example, in the West Lake, Qiantang River and other waters, only when the water quality is clean will black swans patronize. Huating Lake, like Thames Town, may also attract black swans because of its excellent ecological environment. Black swans' choice of habitat reflects their pursuit of quality of life.
2. Feeding habits
The black swan's food is almost entirely plants, including all kinds of aquatic plants and algae. Common aquatic plants are Typha Typha, Poria cocos, Myriophyllum, Saussurea, etc. In the case of artificial breeding, black swan can choose concentrate feed, green feed, bone meal, calcium powder, cod liver oil and other feeds. In addition, black swans occasionally eat insects, but this is only a rare case. For example, in Jinghe Road, Beiheng, Xinhong Street, black swans feed on the roots, stems, leaves and fruits of aquatic plants, and occasionally eat shrimps and mollusks from eat small fish.
3. Flight ability
Black swan has strong flying ability. On a long flight, they will be arranged in a word line or a V-shape. When flying long distances together, the wings of the black swan flap slowly and sometimes whistle. In flight and on the water, all kinds of noisy tones will be made, and a series of soft bass notes will be made, and they tend to whistle when disturbed on the way. When flying, the team of black swans is well organized, just like swans and geese. The black swan in front flaps its wings to generate an updraft, and the black swan behind it follows closely. This airflow can be used to fly faster and more laborsaving. This way of flying not only embodies the team spirit of black swans, but also shows their survival wisdom in nature.
Fourth, the arrogant performance of the black swan
1. picky about the environment
Black swan has high requirements on water environment, and only waters with good water quality will patronize it. From many examples, we can see that the black swan is picky about its habitat. For example, Swan Lake in Shanghai Zoo is home to many kinds of swans, among which black swans have a special liking for areas rich in water quality and aquatic plants. Shanghai's climate is very suitable for black swans. The open waters and rich aquatic plants of Swan Lake in Shanghai Zoo bring full sense of security to black swans. Huaxiang Greenland in Xinhong Street and Beiheng Jinghe Road next to the "four-leaf clover" are also the favorite habitats of black swans. According to professionals, the black swan is a little picky about the living environment, and likes to settle in the waters with clean water, rich food and no one to disturb. The black swan raised by residents in the community of Leiden Town, Zhongshan Street, Songjiang, also chose to settle down there because of the improved community environment, clean water, rich food and no one to disturb. Black swans' picky about the environment reflects their high requirements for the quality of life, and also shows their arrogant side.
2. Elegant display
Black swan likes to show its elegant posture, and does not dodge when taking pictures, but shows it generously. When Liu Shishi appeared at the event, the black swan style showed elegance, a black turtleneck dress, slender and slender neck lines, shoulders and waist complement each other, and the charm from bone to flesh made people feel her unique charm. Mabel Yuan's today's activity look, the black swan deep V dress shows beautiful shoulder and neck lines, which is more elegant and gentle against the green. The same is true of black swans in the natural environment. When they swim in the water, they paddle their feet gently, and their slender necks bend slightly, as if they were meditating and enjoying the beautiful scenery around them. When flying, the black swans are arranged in a word line or a "V" shape, their wings are flapping slowly, and sometimes they whistle, which is like a king in the air, majestic and noble. Whether human beings imitate the shape of black swan or the performance of black swan in nature, they all show their elegant posture and show their beauty generously.
3. Bad temper
The black swan is as arrogant as the "black-hearted queen", with strict control over food and territory, and attacks on human beings. Like the black swan, the flat-billed swan in Shanghai Zoo has a strong sense of territory, is keen on fighting, and even occupies the nest made by the black swan. The black swan lost the fight and ran away from home in a fit of pique. What a temper. A black swan in Suzhou ran away from home after losing a fight with other swans, and was injured in its flippers. It was sent back to Dongyuan Management Office by well-meaning citizens and police. Black swans also have strict control over food. On Jinghe Road in Beiheng, Xinhong Street, black swans almost completely feed on the roots, stems, leaves and fruits of aquatic plants, and occasionally eat shrimps and mollusks from eat small fish. Black swans may also be aggressive to humans, showing their obnoxious side. This arrogant temper makes the black swan unique in the animal world.
V. Implication and symbol of the black swan
1. The artistic conception of aloof
The black swan symbolizes aloofness and loneliness, and represents a lonely and arrogant artistic conception. Unlike other groups, the black swan often swims gracefully in the quiet waters alone, as if immersed in its own world, keeping a distance from the noise and excitement around it. Its slender neck is slightly bent, like a lonely thinker, showing inner pride and firmness in meditation.
Many lonely but proud people like black swan, perhaps because they see their own shadow in it. Black swan does not have the pure joy of white swan, but it has a unique mystery and depth. It flies in the night sky, like a lonely soul, looking for its own direction in the dark. This lonely and arrogant artistic conception makes people feel a different kind of beauty, a spirit of not going with the flow and sticking to themselves.
2. A symbol of nobility
As an ornamental rare bird, the black swan symbolizes nobility and elegance, and has extremely high ornamental value and economic value.
The nobility of the black swan is first reflected in its beautiful appearance. It has the longest neck among swan species, and it is arched or upright in an elegant "S" shape, showing a noble gesture. The curled feathers are pure black, flashing mysterious light in the sun, as if they could devour everything around them, but they inadvertently reveal a blue-green luster, like stars in the deep universe, which makes people daydream. The red or orange-red waxy beak, with a white stripe near the end, is like a bright gem, adding a splendor to the black swan.
The nobility of the black swan is also reflected in its behavior. Whether swimming in the water or flying in the air, the black swan always maintains an elegant and calm posture. In the water, it paddles its feet gently, and its slender neck bends slightly, as if enjoying the beautiful scenery around it, and as if meditating on the mystery of life. When flying, the black swans are arranged in a word line or a "V" shape, their wings are flapping slowly, and sometimes they whistle, which is like a king in the air, majestic and noble.
In addition, the nobility of the black swan is also reflected in its requirements for the living environment. It has high requirements for the water environment, and only waters with good water quality will patronize it. It likes to inhabit shallow waters, coniferous forests, lakes, ponds and other places. These places usually have good water quality and lush grass, which provides rich food and a safe habitat for black swans. The black swan's high demand for quality of life shows its nobility and elegance.
With its unique beauty and noble temperament, the black swan has become a remarkable landscape in nature. Its existence makes people feel the magic and beauty of nature, and also makes people have a deeper understanding of nobility and elegance. Black swan is often used to symbolize nobility, elegance and mystery, whether in literary works or artistic works. Its unique charm attracts the eyes of countless people and has become an eternal symbol of beauty in people's hearts.
Six, the distribution range of black swan
1. Country of origin
Black swan is native to Australia, mainly distributed in southeast and southwest Australia. Living in the whole southern Australia, extending to Tasmania in the south and townsville in Queensland and port hedland in Western Australia in the north. As the origin of black swan, Australia is rich in aquatic plants such as lakes, rivers and marshes, which provides an ideal habitat for black swan. In many waters of Australia, you can see the elegant figure of black swans, which move in groups and show their unique charm. The fourth largest city in Australia is known as the "Black Swan City" because it is the settlement of black swans, which shows the large number and wide distribution of black swans in Australia.
2. Diffusion area
With the passage of time, the black swan gradually spread to other countries and regions. Nowadays, black swans have appeared in Britain, western European countries, Spain, China and Japan.
In Britain, there have been many mysterious deaths of black swans. Some swans spin in one direction before they die, and blood is still flowing in their nostrils. After autopsy, they were found to be infected with the new avian influenza virus H5N8. Although the risk of avian influenza virus to human health is very low, it also reflects the survival challenge faced by black swan in Britain.
In China, black swans are distributed in Heilongjiang, Jilin, Liaoning, Xinjiang, central China and southeast coastal areas. For example, recently, a group of graceful black swans once again came to Tuancheng Lake regulation pool, adding a unique scenery to the regulation pool. Tuancheng Lake Management Office's efforts to build the ecological environment have attracted all kinds of birds such as black swan to visit. In addition, the black swan was found for the first time in the waters of Long Island, Shandong Province, which indicates that the distribution of black swan in China is gradually expanding. In China, some black swans escaped to the wild and adapted to survive after artificial breeding. Long Island puts ecological protection in the first place and strengthens the protection of marine ecological environment. The marine biological resources in the region are constantly enriched, providing a good living environment for protected biological species such as black swan.
In Rongcheng, as one of the four largest swan wintering habitats in the world, although the swan wintering in Rongcheng is a big swan, the origin of the black swan is in Australia, which also lets us know the global distribution of the black swan.
In Japan, black swans are also farmed, and some individuals may live in the wild. The spread of black swan not only enriches the biodiversity in these areas, but also brings people more opportunities to appreciate beautiful creatures. At the same time, we also need to pay attention to the living conditions of black swans, protect their habitat and prevent potential ecological risks.
Seven, the breeding mode of black swan
1. Estrus mating period
Black swan has a unique behavior in estrus. The red spots on the pro-goose's mouth are bright, and their feathers are more shiny. The paired black swans are inseparable, playing with each other, chasing each other and touching their necks, which is particularly exciting and affectionate. For example, in Swan Lake, shenzhen safari park, during the breeding season, black swans will touch each other with their necks and their beaks, often forming a heart-shaped "love you" shape. Both sides often dive their heads into the water, then reach out of the water and rub their necks repeatedly to show their love by "kissing their necks". After being sweet and making a positive result, both sides hold their heads high and sing accordingly. Male swans actively chase females at the beginning of estrus, and after pairing, the males always lead the females in front, and often have protective behaviors for females. When walking, the stride is larger and the frequency is faster.
Step 2 build a nest
Parent geese generally choose a quiet, hidden and high-lying location to camp their nests. Female geese are very cautious and vigilant. Once unsafe factors or human interference are found in the process of nesting, they immediately give up the nest and choose a new site. Generally, both men and women nest together, but the division of labor is different. The male is responsible for collecting and carrying nest materials, and the female is responsible for building and finishing. There are two sources of nest materials: natural and artificial. Natural refers to dry branches, weeds and feathers, etc., and artificial refers to putting some straw, dry branches, etc. on the island with less nest materials for them to choose. The base and periphery of the nest are thick branches, and the nest is made of thin branches, leaves, less feathers and fine hay. The nest is irregular and oval, and it takes about 5 ~ 10 days to build the nest.
3. Oviposition and incubation
Black swans will nest soon after nesting, and then start laying eggs. Usually one is produced every other day. Eggs are grayish white in color, with an average egg weight of 150 ~ 165 g. Before laying eggs, the female bird lay uneasily on the nest, kept shaking from side to side, finally calmed down, and lay still for a while before laying eggs. When laying eggs, the female bird crouches slightly in the nest, her wings are slightly spread, her head naturally rises, her eyes look straight ahead, her spirit is concentrated, her abdomen exerts paroxysmal contraction, and her eggs are discharged outwards with blunt ends. It takes 20 ~ 30 seconds to lay an egg. After the egg is laid, the female bird stands, puts the egg in the middle of the nest with her beak, covers the egg with grass, feathers and other things, takes a break and then swims in the water to comb her feathers.
Black swans begin to hatch after laying seven eggs, and generally they hatch by turns, but females are the main ones, and there is no obvious regularity in the rotation of males and females. When one hatches, the other is on guard. Patrol the waters around the nest to keep other animals or people away. During the incubation period, a feeding basin is placed next to the nest, and feeds such as millet, corn, wheat and granular materials are put in it for breeding geese to eat. Parent geese are very cautious when hatching in the upper nest. When turning eggs, the beaks are used to turn eggs from front to back, and the turning angle is 0 ~ 360 degrees. Sometimes, the positions of the eggs are exchanged or interchanged, and the female bird also achieves the purpose of turning eggs by changing the direction of lying and sitting in the nest. In this way, each egg can be heated evenly, so that the embryo can not adhere to the shell membrane, and the embryo movement can also be used to keep the fetal position normal. After the eggs are turned over, the females sometimes continue to hatch, and sometimes they nest to cool their eggs. By cooling the eggs, the humidity in the nest can be adjusted, which can dissipate the metabolic heat generated in the middle and late stages of the embryo, stimulate the embryo development with lower environmental temperature and enhance the adaptability of the chicks to the external temperature. The chick can hear "squeaking" and pecking sound in the shell the day before it leaves the shell, from weak to strong, and after a few hours, the pecking sound gradually increases and the frequency increases. At the transverse diameter of 1.1 ~ 1.6 cm from the blunt end of the egg, the shell was broken with irregular cracks at first and then with small holes. When the broken shell seam reaches two-thirds of the circumference, the hatchling can push the egg shell open and come out smoothly.
4. Young development
The newly hatched chicks have light gray feathers and wet down feathers, so they can't stand and snuggle under the wings or abdomen of the female bird to keep warm. After 2 ~ 5 hours, the feathers are dry and soft, and you can stand. After 8 hours, the chick can stick its head and neck out from under the female's wing to observe the surroundings. If there is any movement, the chick will quickly retract its head. After 1 ~ 3 days, you can go into the water with the parent birds and feed under the leadership of the parent birds. Black swan has a strong protective behavior during brooding. No matter on land or water, it is mostly male and female, and the chicks are in the middle, so people and other animals are not easy to get close to. Young chicks eat young leaves, fruits, insects and so on. First of all, the parent bird picks up the food and calls the chick. When the chick comes to the front, the parent bird puts the food on the ground, and the chick eats it, or directly feeds from the parent bird's mouth. The chicks feed in the water and on the shore with their parents, and choose a dry place to rest after they are full. At this stage, the chicks eat a lot and develop very fast. The order in which chicks' fluff is changed into feathers is the first wing and the whole body. At first, the fluff was light gray, then changed to gray-black, the color gradually turned black, the mouth turned red and white spots were visible at the tip, and finally it became as black as an adult black swan. For example, in Baiquan Scenic Area of Huixian County, a couple of black swans successfully hatched six little black swans in a natural state. After the little swan broke its shell, it quickly followed its mother to play in the lake for food. When it was tired, it got under its mother's wings and took a nap. Father Black Swan is responsible for looking around the water and keeping a high degree of vigilance. On the small island in the center of Lake Biwa near the south gate of Anhui University, a pair of adult black swans gave birth to three baby geese again. The newly hatched baby swans had light gray feathers and wet down feathers, so they couldn't stand, snuggled up under the wings or abdomen of the female bird to keep warm. After two days of hatching, the little swan began to follow the mother goose into the water, while the father goose opened the way in the front, and began to feed under the leadership of her parents, and then returned to the dry place of the island to rest. At this stage, the little swan eats a lot and develops very fast.
Eight, the communication way of black swan
1. Crying and visual signals
Black swan mainly uses telephone calls and visual signals to communicate. In terms of sound, their calls are rich and varied and used in different situations. The black swan's cry is sometimes high, like a dog barking or a bugle call, and sometimes low. When defending the territory, the black swan will make a short and thick "drip" sound, followed by a short and long "drip-quack-quack" sound as a warning and remind its companions. In the triumph ceremony, several black swans will form a circle, constantly vibrating their wings, and at the same time, their heads and necks will stretch and shrink, making a "quack-quack" sound. In addition, the black swan will make all kinds of noisy tones in flight and on the water, and will also make a series of soft bass notes, and tend to whistle when disturbed on the way.
In terms of visual signals, the black swan will communicate through various actions. For example, raising or waving wings to threaten predators or other swans in their territory. When encountering natural enemies, the black swan will flap its wings to make a loud noise, and its neck will stand upright, and its beak will threaten and drive away predators downward. When courting, the courtship behavior of black swan is called "triumph ceremony", and the male swan's wings and chin approach the female swan and call repeatedly. Then the females sing accordingly, and then they alternate their heads in an upright position. After that, the birds put out their necks and lifted their beaks upward, then raised their necks at a 45-degree angle, lowered their beaks at right angles and continued to swim around. These ceremonies are mainly started by males, and the frequency will increase when there are more swans around them. The red spots on the pro-goose's mouth are bright, and their feathers are more shiny. The paired black swans are inseparable, playing with each other, chasing each other and touching their necks, which is particularly exciting and affectionate.
2. Territorial Defence and Triumphal Ceremony
In territorial defense, black swans will use specific sounds and behaviors to protect their territory. When the territory is violated, the black swan will make a short and thick "drip" sound, followed by a short and long "drip-quack-quack" sound as a warning. At the same time, they will wave their wings, with their necks upright and their beaks down, threatening and driving away intruders. Black swans will also strengthen territorial defense through visual display, such as raising or waving their wings to threaten predators or other swans in their territory.
Triumphal ceremony is an important link in the communication of black swan, which is mainly used to strengthen the dual relationship between spouses, parents and little swan, and to declare territory. In the triumph ceremony, several black swans will form a circle, constantly vibrating their wings, and at the same time, their heads and necks will stretch and shrink, making a "quack-quack" sound. This ceremony is mainly initiated by the male black swan. When there are more swans around the swan, the frequency will increase. The triumph ceremony during courtship is even more special. The male swan's wings and chin approach the female swan and call repeatedly. Then the females sing accordingly, and then they alternate their heads in an upright position. After that, the birds put out their necks and lifted their beaks upward, then raised their necks at a 45-degree angle, lowered their beaks at right angles and continued to swim around. Through these ceremonies, the black swans strengthened their ties with each other and showed their territory and status.
Nine, the survival challenge of black swan
1. Natural enemy threat
There are many natural enemies of black swan, such as Australian raven, swamp harrier, black mouse, etc., and they are facing great predation risks. Their eggs and chicks are hunted by Australian ravens, swamp harriers, black rats and voles, bearded vultures, marsupials, sea eagles and other eagles, and sometimes by seagulls and terns. For example, in Yuanmingyuan, four black swans with nests died one after another. According to comprehensive analysis, all of them died from the bite of small carnivores.
2. Impact of human activities
Human activities have had many adverse effects on the living environment of black swan.
Water pollution: Water pollution is one of the major threats faced by black swan. For example, in Swan Lake, Rongcheng, Shandong Province, due to artificial pumping silt to cover the habitat, the beaches where swans live are destroyed, and swans are in danger of life and death. In Swan Lake, Rongcheng, Shandong Province, the largest swan habitat in Asia, the exhaustion of drinking water channels and water pollution in Swan Lake are the root causes of swan death. Of the four main drinking water canals flowing into the lake area, only one river has qualified water quality, but swans are afraid to drink water because of its close proximity to real estate development projects. Among the other three rivers, the abalone farm was built in the upper reaches of Xiaojiang River, which has been turned into a salty river due to the discharge of wastewater; On the Jinshui River bank, due to the construction of electronic component factories and villas, industrial wastewater and domestic sewage have polluted the river; The Huakuang River, on the other hand, stinks because of the garbage dump built by the river. Homeless swans compete for food in garbage dumps and drink inferior water for a long time, which seriously threatens the survival of black swans. In addition, in the place where the black swan should live in heaven, the black and smelly water body has become the culprit of the black swan's illness and infection.
Habitat destruction: human development activities lead to the continuous reduction and destruction of the habitat of black swan. On the famous Swan Lake in Rongcheng City, Shandong Province, hundreds of wintering white swans lingered on the cracked beach in the cold wind, struggling to find water from the cracks, and several young swans died of thirst. It used to be a natural wetland with half sand and half mud, with abundant algae and shellfish. The fresh water stored in the black pine forest in the north converged on the beach along the soft beach, where the swans who came here for the winter ate and drank. However, hundreds of swans are facing the danger of life and death because of the artificial pumping of silt to seal off the habitat of this swan. At the same time, in 1999, 60 million yuan was spent on dredging the bottom of the lake, which led to the disappearance of reeds and marshes and turned into a large dry mudflat, and the water conservation ceased to exist, destroying the habitat of the black swan.
Illegal hunting: Black swan is also threatened by illegal hunting. For example, in Ruzhou City, some citizens posted a video of a black swan suspected of being shot and killed by an air gun in North Ruhe River on the online platform, which was of a bad nature. At present, the Forest Public Security Bureau is investigating the incident further, and has issued a reward notice, collecting relevant clues with a reward of 5,000 yuan, and striving to punish the offenders as soon as possible.
Risk of species invasion: As an exotic species, black swan has been widely introduced in parks, zoos and private farms in China in recent years, and its number has increased rapidly. Although the direct impact of black swan on the local ecosystem has not been obvious yet, its rapid increase in number and wide distribution indicates a potential environmental threat. Black swan has the characteristics of high fecundity, wide environmental adaptability and lack of natural enemies, which makes it possible for them to become invasive species and cause damage to the local ecosystem. For example, black swans are also found in some nature reserves, which is contrary to the original intention of setting up nature reserves and may affect native species and ecosystems in the reserves.
Poor habitat: Black swan has high requirements for habitat, but human activities lead to poor habitat. For example, in the external exhibition area of China Garden Museum, the living environment of two black swans is bad, and the area of their habitat is narrow, which is seriously inconsistent with the activity area required by the two black swans. The area of habitat activity water area is too small, and the water quality is turbid, and there are too many floating objects; The living environment is not good, and rats have been seen eating at the place where they put feed. This has a negative impact on the education of children to treat natural things.
X. Charm and Protection of Black Swan
1. What is the charm
Black swan has become a remarkable existence in nature because of its elegant, noble and arrogant charm. Their elegance is reflected in every movement, whether swimming in the water or flying high, they all exude unspeakable charm. The slender neck of the black swan is elegant "S" shape, just like a noble dancer. The curled feathers of the whole body are pure black, flashing mysterious light in the sun, just like the stars in the deep universe.
The nobility of black swans lies not only in their beautiful appearance, but also in their high demand for quality of life. The picky about the water environment, only choose the waters with good water quality, rich food and no one to disturb, showing its arrogant side. At the same time, the various performances of black swans in the natural environment, such as showing their elegant posture generously and not dodging when taking pictures, all make people feel their nobility and confidence.
The visual enjoyment brought by the black swan is unparalleled. They gently across the lake, like the messenger of the night, elegant and solemn; When flying high, the perfect combination of strength and beauty makes people feel awe. This visual shock makes people feel the magic and beauty of nature.
The black swan also brought people a spiritual touch. Many lonely but proud people like the black swan, perhaps because they see their own shadow in it. The aloof artistic conception of the black swan makes people feel a different kind of beauty, a spirit of not going with the flow and sticking to themselves. It reminds us how important and rare it is to remain unique and pure in a complicated world.
2. Protective measures
Protecting the black swan is of great significance. As a beautiful and rare animal, black swan not only has high ornamental value, but also plays an important role in the ecosystem. Their existence enriches biodiversity and adds a unique landscape to our world.
In order to protect the black swan, we can take the following specific measures:
Habitat protection: Black swans mainly inhabit lakes, rivers and swamps, so it is very important to protect these habitats. Formulate and implement policies for the protection of lakes and rivers, limit the pollution of water bodies by industrial and agricultural activities, restore and rebuild ecosystems, and provide better habitat conditions. Strengthen rural and urban planning and management to avoid the destruction of black swan habitat. Strengthen the control of important waters and prohibit illegal hunting, fishing and bird catching.
Reduce human interference: human activities have had many adverse effects on the living environment of black swan, such as water pollution and habitat destruction. We should try our best to reduce the disturbance to the black swan habitat, and do not feed or harass the black swan at will. Set up warning lines, warning slogans and warning signs in places where black swans haunt, such as parks and nature reserves, to enhance tourists' awareness of caring for animals. Increase the number of security personnel, unblock traffic jams in time, remind tourists to pay attention to safety, stay away from the border, and strengthen supervision. Establish a special watch mechanism, take personal care, actively persuade tourists to take pictures safely, stop irrational behaviors such as feeding and playing in time, and create a civilized viewing atmosphere.
Strengthen supervision: crack down on illegal hunting of black swans. Forest public security and other departments should strengthen the patrol of black swan habitat and seriously investigate and deal with illegal hunting. At the same time, a reward notice was issued, relevant clues were widely collected, and efforts were made to punish the offenders as soon as possible. As for the ecological risks that black swan may bring as an exotic species, it is necessary to strengthen monitoring and management to prevent it from damaging the local ecosystem.
Carry out breeding projects: encourage black swans to breed in a safe environment by setting up special protected areas. Control the feeding and breeding conditions to ensure that the black swan can reproduce normally. Researchers can use modern scientific and technological means to collect the eggs of black swans and incubate them artificially, and then release the young birds to nature, so as to improve the reproductive success rate of black swans and increase the number of wild populations.
Carry out education and publicity: strengthen public awareness and understanding of black swan protection, improve people's environmental awareness, and cultivate a sense of responsibility for protecting animals. Organize lectures and training courses on black swan protection knowledge to popularize relevant scientific knowledge to the public. Use traditional and emerging media channels to publicize the importance of black swan protection. Carry out educational activities on black swan protection in schools to cultivate students' awareness of environmental protection. Set up a volunteer organization to protect the black swan and encourage the public to actively participate in the protection activities.
Protecting the black swan requires the joint efforts of the government, scientific research institutions, social organizations and the public. Only by comprehensively applying various protection measures can we create a good environment for the survival and reproduction of black swan and ensure that this rare species can coexist harmoniously with human beings.
