Living habits of wild animals

1. Lions are the only male and female cats. Lions are huge, with the length of the male lion reaching 180cm and the female lion reaching 160cm. The lion's hair is very short and its body color is light gray, yellow or brown. The difference is that lions also have long manes, such as light brown, dark brown and black, which extend to the shoulders and chest. The longer the mane, the darker the color. Maybe those guys are handsome and brave in the eyes of the lioness and often attract the attention of' ladies'. The lion has a huge head, a wide face, long nasal bones and a black nose. Lions have short ears and round ears (I noticed that some people confuse a puma with a lioness because they both have the word "lion" in their names. In fact, it can be distinguished from the appearance. The ears of a lioness seem to be short semicircles, while those of a cougar are longer and sharper. In addition, lions belong to leopard subfamily in cats, while cougars belong to cat subfamily, which is very different. The lion's forelimbs are stronger than its hind limbs, and its claws are wide. The lion has a long tail with a bunch of long black hair at the end. Lions living at the north and south ends of the African continent have more developed manes, extending to the back and abdomen, and are also the largest. However, under the special care of human shotguns, these two subspecies have become extinct one after another. Asian lions in India are smaller and have shorter manes than their African brothers. They are also on the verge of extinction. Lions used to live in southeast Europe, the Middle East, India and Africa. Lions living in Europe were extinct due to human activities around 1 century, while lions living in Asia, especially India, were almost hunted down by British colonists who conquered India at the beginning of the 20th century (completely showing the lewdness of human beings after the poor became rich)! Fortunately, Indians, who have always regarded lions as sacred animals, finally saved them and placed them in Gil National Forest Park in Gujarat, northwest India. There are about 300-400 lions now. After the extinction of Asian lions living in West Asia due to poaching, Jill National Forest became the last habitat of Asian lions ... Lions living in Africa are now basically scattered on the mainland from sub-Saharan to the north of South Africa, living in vast grasslands, open woodlands and semi-desert areas, and are also found in mountainous areas with an altitude of 5,000 meters in Kenya. There are many subspecies of lions, and anthropologists have made different classifications of lion subspecies. At present, this site is subject to the domain (1) 13-level classification of Lioncrusher. At present, two subspecies have been extinct by human beings: lions usually prey on larger prey, such as bison, antelopes, zebras, and even young hippos, elephants, giraffes and so on. Of course, small mammals, birds and so on will not be spared. Sometimes they take advantage of their large size to snatch the fruits of other carnivores, such as which leopard is in the wrong place at the wrong time, and even kill each other for it. In addition, they will eat the carrion of animals.

The lioness in the pride is basically stable, and they usually stay in the same pride from birth to death. Of course, the lions will also accept the new lioness. However, lions often rotate. They usually stay in a group of lions for only two years (but there are also records as long as six years). They are either driven away by younger and more attractive men, or bored and leave home to find new relationships and families. Also, the young lion who just grew up will be driven away by the compulsory independence system of lions (I suddenly thought, Khan, irresponsible speculation, I am afraid that the young lion will be forced to be independent for a reason, not the lioness ... because the lioness is a predatory labor force among lions, no fool drives away the labor force, and too many male lions stay in the lions, which is useless except consuming more food. So I have to get rid of those idle young slackers ... well, once again ... every lion comes like this, when his daughter-in-law becomes a woman ... er ...: d), in this way, there will be a lot of homeless lions on the grassland, including young people who are still wet behind the ears, young adventurers who still exude charm, and old people who are defeated and driven away. Sometimes these vagrants act alone and live in the dark, and sometimes they simply form a male support group. Before one of the members conquered another group of lions, they were good buddies who shared weal and woe, wandering around the grassland and tracking the migrating prey groups. It is said that some lions are so skilled and charming that they can control other lions nearby and maintain two "homes" at the same time. Alas, this doesn't seem very kind ... the inn ... Of course, the male members of the lions are not only responsible for half of the reproductive tasks (hum! ), but also against vagrants wandering on the grassland, which is not only related to their status in the pride, including mating rights, but also related to the lives of their descendants. Because winners often kill unarmed children in the pride and force the lioness in the pride to marry them. Lions' territories vary in size, such as kalahari desert (does anyone remember anything after seeing this name? The movie Gods must be crazy! ! Lions may get 1 19-275 square kilometers, while lions living in Nairobi National Park will get at most 3 1 square kilometers. The largest territory can exceed 400 square kilometers, and the border is bounded by shit. Sometimes the territories between adjacent lions sometimes overlap, but they rarely use violence to solve this problem. What a reasonable animal. The lioness in the pride may enter the mating state at any time, and the lioness is always in sync. This strange and interesting phenomenon has not been fully understood by scientists. However, this ensures that the children in the lion group are basically the same age, and each mother can breastfeed different children. When some mothers go out hunting, the remaining mothers will be duty-bound to look after all the children. Moreover, the barren lioness will take care of the lion's children, lick their fur and play with them. Of course, the lion's biggest "heavenly" enemy is modern humans armed to the teeth (I'm afraid even an angry domestic cat can't beat a completely unarmed human! )。 Moreover, most of their hunting has nothing to do with survival, just to satisfy the abnormal desire to kill. It is under its impetus that two subspecies of Africa are inexplicably extinct, while Asian lions are almost extinct. Now this abnormal behavior is finally much less. However, African lions now face habitat loss and diseases. Outbreaks of grassland infectious diseases can kill thousands of animals in a short time, such as tuberculosis and feline AIDS (FIV). As far as I know, there is already a vaccine for cat AIDS in the veterinary field, but I don't know whether it can be fully applied and how effective it is. Asian lions also face habitat problems. More than 300 Asian lions are crowded in the 1400 square kilometer reserve, which is really stressful. It is said that there are plans to transfer some Asian lions to other protected areas so that other lions can survive in case of disease outbreaks or other disasters. However, it is really difficult to implement such a plan in this country with huge population pressure. Judging from the current situation, Asian lions are listed in Appendix I of CITES, while African subspecies are listed in Appendix I..2 Elephants are the largest mammals living on land. There are two typical elephants-African elephants and Asian elephants. African elephants have big and soft ears, mainly living in African grasslands, while Asian elephants have small ears, mainly distributed in India, Sri Lanka, Thailand, Myanmar and Yunnan, China. Elephants eat a lot. An adult elephant needs to eat about 300 kilograms of food a day. They mainly feed on leaves, fruits, branches and bamboo. Elephants are so strong that they can knock down trees easily. Therefore, even the fiercest lion is sometimes afraid of it. Elephants are very clever and can communicate with each other in sounds that humans can't understand. There are five kinds of elephants now known. When the weather is hot, the elephant's two big ears are used as fans to dissipate heat. When angry, elephants also dance angrily with open ears. Ivory ivory is not only a tool to eat food, but also a weapon to fight the enemy. Elephant nose: Elephants have a very sensitive sense of smell. The nose has no bones, but is made up of strong muscles, which is very powerful. The front end of the nose is flexible and can hold small things.

Elephant foot: the forefoot of the foot is 4 toes and the hind paw is 3 toes (the forefoot of the Asian elephant is 5 toes and the hind paw is 4 toes). When your feet cross, the root of your instep becomes a meat pad. There are only five subspecies of tigers in the world, namely, Bengal tiger, Southeast Asian tiger, Suman tiger, South China tiger and Northeast tiger. Among the existing five subspecies, China has three subspecies (Northeast Tiger, South China Tiger and Bengal Tiger), but the total number ranks at the bottom of the world.

1, the origin and morphological characteristics of three tigers in China.

Northeast Tiger refers to all tigers produced in China, the former Soviet Union and northern Korea. In China, it is distributed in Jilin Province and Heilongjiang Province, but its habitat has become very small. In the wild, they mainly live in forests, jungles and overgrown places, especially in mixed coniferous and broad-leaved forests. There is no fixed nest. I like living alone. Every tiger has a certain place. Night activities, good at swimming, 6 ~ 8 km wide river, easy to cross. In terms of body shape, the Siberian tiger is the largest and most beautiful subspecies, with a body length of 4m and a weight of 380kg. The whole body hair is light yellow and long, with sparse markings. The chest, abdomen and inner limbs are white hair, and the tail is thick and dotted with black rings. Hunting by sight and hearing. When hunting, wait in ambush or sneak up on the prey carefully. Then grab the prey by biting the key parts of the nape of the neck, kill it and drag it to a hidden place to eat. Wild animals mainly prey on wild boar and herbivores. Estrous mating in winter, pregnancy 105 ~ 1 10 days, 2 ~ 4 offspring per fetus, sexual maturity of 4 ~ 5 years, life span of 20 ~ 25 years. It is a national first-class protected animal.

South China Tiger, also known as Chinese Tiger, is a specialty of China. This subspecies is widely distributed in South China, East China, Central China and Southwest China, but it is rare in the wild. Living in wild mountains, bushes and overgrown places. Sex is lonely and intense. Living habits are similar to those of the Northeast Tiger. In the wild, they mainly prey on wild boar, yellow meat, deer and so on. There is no fixed breeding season. The gestation period is 100 ~ 106 days, and each fetus has 2 ~ 4 offspring. Sexually mature at 3 ~ 4 years old, with a life span of 20 years. South China tiger is smaller than Northeast tiger. Short hair; Dense patterns and dark colors; The tail has the most black spots. Belonging to the national first-class protected animals, it is now facing extinction and is one of the most endangered animals in the world.

Bengal tiger, also known as South Asian tiger, is distributed in Myanmar, India, Thailand, Malaysia and other countries. In China, it is mainly distributed in Yunnan and eastern Tibet. This kind of tiger lives in forests, mountains and hills. Nocturnal walking mainly feeds on ungulates such as wild boar and deer, and occasionally attacks people and livestock. There is no fixed breeding season. The gestation period is 100 ~ 106 days, and each fetus has 2 ~ 4 offspring. Sexually mature at 3 ~ 4 years old, with a life span of about 20 years. Bengal tiger is smaller than Northeast tiger, bigger than South China tiger, with short hair and narrow and dense black stripes. It is also a national first-class protected animal.

The tiger is called the king of beasts, which is what we usually see. Tigers have stripes on their heads. We in China think that there are three horizontal lines on the tiger's head, like the word "Wang". Why do we say it is the king of beasts? First, it is relatively large and feeds on other animals. It is at the top of this food chain. It lives by eating other animals, so it plays an important role in maintaining ecological balance. So it belongs to the king of beasts, and the tiger is an important part of our cultural tradition in China. As we said, where is the tiger in the zodiac? Is the third place, right! Everyone knows that there are many idioms about tigers, such as "tiger leaping", "tiger gaining momentum", "tiger adding wings", "talking about the color change of a tiger" and "nothing ventured, nothing gained". These idioms are very similar to some habits of tigers, which were summed up by our common people in their long-term contact with tigers. They can fully reflect some habits of tigers.

How on earth did the tiger originate? We just talked about the leopard that appeared about 5 million years ago. Where did it originate? It originated in Asia and then radiated from Asia. It is generally believed that tigers originated in eastern Asia, especially in China. In our country, it is earlier than other members of the leopard genus, such as lions or leopards, and it first differentiated about two million years ago. China's South China Tiger is unique to China. It is considered as the ancestor of all tigers and a primitive group. Tigers are now divided into eight subspecies. Unfortunately, three of them are extinct. First, briefly introduce the distribution of various subspecies: Bengal tiger, distributed in India, Myanmar, Nepal, eastern Tibet and southern Yunnan. Its body color changes greatly, including white and black. The white tiger that we will talk about later is a morphological change of this Bengal tiger. It is not the albino individual that we humans see, it is not an albino individual, but the change of its body color. It is about 2.9 meters long and weighs 220 kilograms. The female is slightly smaller, about 2.5 meters long and weighs 140 kg. 4. The red-crowned crane (Grusejaponensis) is a large wading bird, and its length is over1.20m.. The whole body is almost pure white, and only the secondary and tertiary flight feathers are black. The bare part of the head is bright red, hence the name Dante. Red-crowned crane is a migratory bird, which nests and breeds in swamps in Heilongjiang and Jilin provinces in Northeast China every spring, mainly distributed in the roots and stems of aquatic plants, small fish and shrimps, mollusks. After autumn, they went south to Jiangsu for the winter.

In people's minds, cranes have always been a symbol of all kinds of beautiful things. At present, there are 15 species of cranes known in the world, and there are 9 species in China, accounting for almost two-thirds of the cranes in the world. Among the nine kinds of cranes, the red-crowned crane is the most impressive one. In ancient China, the habits of cranes and various legends about cranes all refer to red-crowned cranes, which are outstanding representatives of crane families.

The life span of the red-crowned crane can be as long as 50-60 years, so since ancient times, people have always called it a longevity animal together with turtles, which is a symbol of longevity. Therefore, in many Chinese paintings, painters always draw red-crowned cranes and pine trees together, which is called "the picture of pine cranes" as a symbol of longevity.

Red-crowned cranes are elegant and delicate in temperament. It is often swaggering, showing an air of arrogance and chic, and like an unrestrained and unrestrained person, so it is regarded as a "fairy bird" in the history of our country. In many myths, legends and poems, immortals and hermits are often accompanied by cranes, which is a symbol of immortality, so the red-crowned crane is also called "crane", even in many zoological works, it is still given the name of "crane". Red-crowned crane is a national first-class protected animal. At present, the State Council regards Zhalong in Heilongjiang and Yancheng in Jiangsu as the most important nature reserves of red-crowned cranes in China.

Cranes are mainly wetland birds, and the "evolutionary chain" is related to cranes. In this ethnic group, there are all kinds of crake, black water chicken, red-brained chicken, Ze chicken and white-brained chicken. Crake is small, short and fat, and likes to hide. In terms of looks and manners, it is really difficult to compare with elegant cranes. However, there are subtle signs that they do belong to the same source. For example, when molting, it is all "one-time" replacement, not "one by one"; Also, they all choose to nest and hatch eggs on the flat ground. Different from other species, the blue crane and its close relative, the grey crane, have been "liberated" from the wetland. For them, the wetland is just a habitat. As for foraging and nesting, they will all be done on land. It's just that the grass where blue cranes choose to nest is often close to wet areas. Most existing cranes, such as the gray-crowned crane and the drooping crane in South Africa, also leave the wetlands to look for food elsewhere, at least occasionally. But during the breeding season, they will definitely return to the wetlands.

Because it has been able to "liberate" from limited wetlands, it is one of the three major crane species in southern Africa. Blue crane has become the largest and most widely distributed species. Perhaps because they have elegant imperial temperament, they are very loyal to their spouses. This makes them enjoy a high reputation in long-standing folklore. In crane society, once a spouse is determined, he will be "faithful" until one of them dies. The most amazing thing is that as long as the two sides "get married", they will always be inseparable, and few of them are far from the other's vision. Even in the non-breeding period, when "husband and wife" want to temporarily return to the group to live a collective life, they will still love each other, and they will always maintain the intimate state of "husband and wife never leave". Another attractive feature of cranes is their charming dance. Dancing is their custom. A dancer can be a loving couple, or a small crane in a crane group looking for a partner.

Interesting living habits

5. Peacock 1. Hi quiet, afraid of shock. Peacocks like quiet and comfortable living environment, all kinds of noise and other animals? If dogs interfere, it will affect the growth and development of peacocks and reduce their egg production and fertilization rate.

2. Flight ability. Peacocks are very big, with an average of about 5 kilograms each, but they have strong flying ability.

3. omnivore. Peacock is omnivorous and coarse fodder, and widely eats seeds, eggs and insects of Gramineae and beans. Therefore, the combination of multiple feeds can be a good diet.

4. Habitat preference. Peacocks like to perch on perches no matter day or night.

5. I like the shade and am afraid of the rain. Peacocks like cool weather. The weather is hot and the temperature is high. Peacocks seldom move. On rainy days, there is water in the playground, the sanitary conditions are not good, and the incidence of peacocks is high. Seven, monkey monkey is a common name. Many animals in primates are called monkeys. Primates are 1 order mammals. The highest group in the animal kingdom, with developed brains; The track faces forward and the track spacing is narrow; The toes (fingers) of hands and feet are separated, and the thumb is flexible, and most of them can hold hands with other toes (fingers). Including prosimia and simian suborder. Protomonkey suborder has a fox-like face; No cheek pouch and buttock callus; The forelimb is shorter than the hind limb, and the thumb and big toe are developed, which can be opposite to other fingers (toes); The tail should not be curled or missing. Ape suborder has a human face; Most of them have cheek pouches and hip calluses; Most forelimbs are longer than hind limbs, and some big toes degenerate; Tails are long, some can be curled, and some have no tails. According to the geographical distribution or nostril structure, the suborder simian is divided into wide-nosed monkeys, also known as new world monkeys; Narrow-nosed monkeys, also known as old world monkeys. This order includes 1 1 family, about 5 1 genus, 180 species, mainly distributed in warm areas of Asia, Africa and America. Most of them live in forest areas. The largest primate is a gorilla, weighing 275 kilograms, and the smallest is a bonobo, weighing only 70 grams.

Primates' skulls are mostly large and spherical, which is caused by the shortening of jaws and the flattening of faces. The posterior orbital process develops to form a bony eye ring or a closed eye socket; Most species have short noses, and their sense of smell is not as good as sight, touch and hearing. Some lower species have highly developed olfactory centers in their brains, and they rely heavily on the sense of smell. Some lemurs have long noses. The nasal bones of snub-nosed monkeys and dolphin-tailed langurs degenerate, forming upturned nostrils. The nose of a proboscis bird is big and long. These special types are formed by the development of muscle or cartilage. The big toe of the foot can abut against the other toe, making the hands and feet become grasping organs. The five fingers of primitive monkeys can only be flexed and extended at the same time, and cannot be used alone. Palmar surface and □ surface are exposed, with finger and toe lines and different patterns. The foot pads are soft or wide, and all of them are flexible except the black apes. Most fingers and toes have flat nails. Generally speaking, there is little difference in the length of forelimbs and hind limbs, but the forelimbs of Red Tide Insects and Scarabaeidae are much longer than the hind limbs. Apes and humans have no tails. In species with tails, the tail length varies greatly, from only one protrusion to exceeding the body length. The tail of most species in the family Cephalaenidae has the function of grasping and is called the "fifth hand". Some old world monkeys (such as baboons) have brightly colored faces, buttocks or breasts, especially during the breeding season. The buttock has a hard lump composed of hard skin, which is called the buttock callus.

1 nipple in most species is located in the chest or armpit, while 1 nipple in monkeys is located in the abdomen. Male penises droop, most of which have penile bones, but tarsiers, marmosets, humans and some species do not. The testicles are wrapped in a bag. The female body has a double horn uterus or a single horn uterus. Body coat, some soft and thin, some thick and hard, or local long, or hair with different colors of links. Some hair on the top of the head is very long, forming a tufted crown, or short, flat-topped, or bald and hairless. Some people have long hair on their cheeks or chin, which is shaped like a beard. Some shoulders, backs and hips are covered with long hair. Some body hair is gorgeous.

Most primates live in different forms of arboreal or semi-arboreal life, and only ring-tailed lemurs, baboons and marmosets live in land or rock areas. Usually small groups, but also large groups. Most people can walk upright, but not for long. Most of them are active during the day, and at night they are refers to monkeys, some big lemurs and night monkeys. Japanese lemurs and Japanese lemurs are in dry and hot season in summer.

Sleep for a few days to weeks.

Most of them are omnivores, eating plant or animal food. There are different ways to choose food and feed. For example, monkeys are good at picking bugs in tree holes or crevices. Orangutans eat a lot and spend most of their time foraging. The stomach of colobus monkeys has a special structure, and most species eat plant food containing a lot of crude fiber.

Breeding 1 ~ 2 times a year, each fetus 1 offspring, and a few can have up to 3 offspring. Larvae grow slowly. Crawling on the mother's chest and abdomen or riding on her back during lactation, carried by her mother. Sexually mature females have menstruation, and males can mate at any time. Only lower monkeys, such as lemurs, sloths and lynxes, have a certain mating and breeding season.

The skull features of Dendrolimidae are very similar to those of some very primitive monkeys. Many anatomists and paleontologists have listed it as a primate, but its external morphology and ecological habits are very different from those of primates. Therefore, modern taxonomists have classified it as Dendrolimidae independently.

There are many kinds of parrots. I don't know what the landlord means ... for example:

Morphology, Life Habits and Feeding Management of Peony Parrot

Peony parrots are also called lovers parrots, black-headed parrots and wax-billed parrots. There are 9 wild primitive species, except 1 species distributed in Madagascar, and the other 8 species are distributed in Tanzania, Nyaganda, Ethiopia, Sudan and other places in Africa.

The peony parrot is about 16 cm long and weighs 40 ~ 50 grams. The mouth is red. The iris is dark brown. The head is red, gray and black, the eyes and wax film are white, the neck has a red-yellow band, the upper chest is orange-red, and the back and wings are green. The wings are covered with feathers and flying feathers. They are emerald green, and the wings are black. The tail is short, round and green. Feet are gray from head to toe. Men are thinner than women and women are bigger than men. The male bird has a small head, a thick neck and a protruding forehead. The pelvis of a male bird is narrower, while that of a female bird is wider. After artificial breeding, more than 0/00 varieties of peony parrot/kloc have been cultivated.

Wild peony parrots inhabit tropical jungles and grasslands and often live in groups. The song is noisy and the wings flap quickly. But the flight distance is not far. Feed on the seeds, fruits and buds of plants, especially on all kinds of sweet berries. Nest in tree holes, cracks in buildings or cracks in rocks. I like to bite off bark and leaves, tear them into pieces and put them in my nest. Each nest lays about 4 eggs. Parents hatch for about 18 days, and both sexes hatch after 1 month.

Peony parrots can be kept in metal cages the size of hibiscus cages. Feed is mainly rice, millet, broken corn, millet, hemp seed, sunflower seeds, peanuts and so on. But you can't feed too much fat feed, otherwise it will cause shedding. Green feed is vegetables, apples, etc. Vegetables are indispensable. Insufficient supply will give birth to unfertilized eggs and sometimes peck feathers. In winter and breeding season, foods with high fat content can be appropriately increased to provide sufficient energy, but obesity should be prevented. In general, barnyard grass, rice and millet can be mixed and fed at the ratio of 3: 2: 2, and hemp seed, sunflower seeds, oyster powder, vegetables and fruits can be added. Do a good job in cleaning and hygiene, clean up the feces in time, and clean the cage 1 ~ 2 times a week. The bottom of the cage should be covered with fine sand. Drinking water should be clean and water bath should be provided frequently. Feed should be added in time, the supplied vegetables and fruits should be fresh, the leftover vegetables and fruits should be taken out in time, and the feed should not be moldy. Peony parrots can lay eggs all year round except molting. Generally, females can lay 3-5 litters a year, with 6-8 eggs per litter, and the incubation period is 17- 19 days. During the whole incubation process, the male stays outside the nest to take care of and feed the female, and the female just eats. Don't drink water, defecate or leave the nest. It takes 35 to 40 days for chicks to leave the nest after hatching, and they still need parents to feed them for 2 weeks before they can live independently. You can make an 80 cm× 60 cm× 40 cm birdcage for breeding. The birdcage should use 12 lead wire, and the diameter of the net should not exceed 2 cm to prevent the birds from flying away. An artificial nest box of 20cm×16cm× l6cm was put in it. A circular entrance with a diameter of 6cm was opened in front of the box, and a wooden platform was set under the entrance for birds to step on when they came in and out. The wooden board of the nest box should be thicker, and 3 ~ 5 round holes with a diameter of 0.5 cm should be left at the bottom to facilitate ventilation and discharge excess water. Large cages are easy to breed in groups. A cage 3 meters high, 3 meters long and 2 meters wide can feed 20 pairs. There are many perches in the cage for birds to climb and inhabit. The artificial nest box is made of hardwood, with a length of 20cm, a width of 16cm and a height of 25cm, and a hole with a diameter of 6cm is opened at 1/3. There is a small bed board that goes in and out of the hole. The artificial nest box can be divided into two layers, the lower layer is covered with 3 mm thick dry sawdust. The nest box is hung high to provide hay, which is brought into the nest by the birds themselves. You can also hang thick bamboo horizontally and make a hole in each bamboo hole for nesting. In short, the number of nesting boxes is more than the logarithm of feeding. In the process of feeding, minimize interference and alarm. The feed is supplemented with powder consisting of bone powder, calcium powder, multivitamins, eggs and corn flour. After mating freely, male and female birds love each other, comb and feed each other, and lay eggs after mating. After the chicks leave the nest, parents can separate the cages after feeding them for more than 10 days, so that parents can continue to breed the second nest.

Elk (also known as the Four Elephants) live in swamps and beaches. Live in groups and travel daily. Love water, good at swimming and trekking. Feeding on weeds and aquatic plants.

2. Elk is a rare animal in the world. Its horns are like deer, its neck is like camel, its tail is like donkey, its hooves are like cattle, and its hair is light brown. But on the whole, it is not like any animal, so it is also called "four unlike". Elk is gentle and feeds on plants. Elk Island covers an area of about 3 square kilometers. According to the living habits of elk and the guidance of experts, there is a swamp of about 2000 square meters in the center of the island, with a long-term water depth of about 0.5 meters and dense reeds beside the water. There are all kinds of small trees and weeds on the island. The island is surrounded by artificial iron fences and bamboo fences. Today, elk, a rare animal in the world, lives leisurely on this island. They sometimes play in the water; Sometimes eat grass; Sometimes chasing and running; Sometimes they walk side by side ... but at any time, they always stay together and live in groups.

Mammals, Artiodactyla, Cervidae. Commonly known as the four unlike, because the tail is like a donkey, the hoof is like an ox, the neck is like a camel, and the horns are like deer. This rare animal was originally a specialty of China, which originated in the late Early Pleistocene, more than 2 million years ago. Its fossils are distributed from Liaoning Province in the northeast of China to the south of the Yangtze River, almost all over the eastern part of China. The wild elk population became extinct in the second half of the19th century due to a large number of human hunting and climate change. In the Qing dynasty, only a group was raised in Nanhaizi, a suburb of Beijing in the Royal Hunting Garden. 1865, the French missionary David found the elk in the partition wall of the hunting park and bribed the breeder to get the skin and skull of the elk. The following year, the elk was named after David. Since then, Nanhaizi Elk has flowed into many zoos in Europe. /kloc-in 0/900, Eight-Nation Alliance invaded Beijing, and with the flood, all the milu deer in Nanhaizi were wiped out. In 1950s, several breeding animals were brought back from England. 1985, 20 animals were brought back from Wubang Temple in England and settled in Nanhaizi, the ancestral home, to rebuild the population. At present, another milu deer breeding center in China is Jiangsu Dafeng Milu Reserve.

It was once widely distributed in all parts of China, and then the wild species became extinct. 19 was smuggled abroad, and only 18 propagated in groups in Ubang Temple in England. 1956 returned to his hometown for the first time. Elk (also known as the four elephants) live in swamps and beaches. Live in groups and travel daily. Love water, good at swimming and trekking. Feeding on weeds and aquatic plants.

Male elk have horns, up to 80 cm long, which are replaced every two years. The male has a shoulder height of1-3m, a body length of over 2m, a weight of about 200kg and a long tail. The female weighs only 100 kg, and the tail length is about 60 cm.

The breeding period is from June to August, and there is a courtship struggle. Pregnancy is about 10 months, each baby 1. About 3 years old, sexually mature, life expectancy of about 20 years. Beijing Zoo 1956 began to be exhibited, and 1975 was successfully bred.

Elk is a protected animal in China, because its horns are like deer, its head is like a horse, its body is like a donkey, and its hooves are like cows. Some people say that its horns are like deer, its neck is like camel, its hooves are like cattle, and its tail is like donkey, so it has the name of "four unlike".

Jiangsu Dafeng Elk National Nature Reserve is located on the coast of the Yellow Sea in the middle of Jiangsu Province, with a wetland area of 78,000 hectares. The landform is composed of woodland, ludang, grass beach, swamp and salt bare land, which belongs to a typical yellow sea beach wetland. There are many kinds of biodiversity with global significance, which was listed in the list of internationally important wetlands in 2002. In July 2002, the UNDP/GEF project "Conservation and Sustainable Utilization of Wetland Biodiversity in China" was officially launched in this nature reserve. The project has greatly improved the management level of nature reserves by carrying out activities such as capacity building, community publicity, public training and equipment assistance.
