Guangzhou Zoo is located in Yuexiu District, Guangzhou City. It is adjacent to the 19th Route Military Cemetery in the east, Huanshi East Road in the south, Yunhe Road in the west, and Xianlie Middle Road in the north. There are two entrances and exits, the south gate and the north gate, and both doors have parking lots. It was completed and opened in 1958 and covers an area of 42 hectares. In 2013, it received 4 million tourists.

Guangzhou Zoo has more than 450 species (2013) of mammals, reptiles, birds, fish and other animals selected from all over the country and around the world, and more than 4500 (only), many of which belong to the world's rare birds and beasts. There are 35 species of national first-class key protected animals such as giant pandas, golden monkeys, and black-necked cranes, and 32 species of national second-class key protected animals such as red pandas and white-napped cranes.

Guangzhou Zoo is also a plant display garden. There are more than 200 kinds of trees and more than 100000 trees planted in the park

The predecessor of Guangzhou Zoo was Yonghan Park established by the National Government in 1928 on Zhongshan 4th Road in Guangzhou City. It covers an area of 2.2 hectares and exhibits more than 60 species of animals and more than 200.

In 1950, Yonghan Park was renamed People's Park (now Guangzhou Children's Park).

In May 1955, it was officially named Guangzhou Zoo.

In July 1956, the Mayinggang area on Xianlie Road was requisitioned as a new site for the zoo.

In October 1958, the new site was completed and opened.

Since 2006, the park has been recognized as a science popularization education base in Guangzhou City, a youth science and technology education base in Guangdong Province, and a national youth science and technology education base.

In 2007, Guangzhou City participated in the National Science Popularization Work Day. In 2009, the Guangzhou City government hoped to relocate the zoo to Maofeng Mountain, but it was unable to relocate due to various reasons such as high relocation costs and high public opposition.

In August 2014, Guangzhou Zoo completed the design of the upgrade, with a total investment of 81.53 million yuan in the upgrade project

There are three lakes in the middle of the Guangzhou Zoo. There are fountains in the lakes and small islands where animals live. There are many wild birds and animals on the lakes. Swim around freely. There are pavilions built in many places along the lake with beautiful scenery.

The black-necked swan (scientific name: Cygnus melancoryphus) is a swan found in South America. Its body posture is very similar to that of a giant swan. It is a rare bird. The feather color of the male and female black-necked swan are very similar, except that the female is smaller than that of the male. With a body length of 90-130 centimeters and a weight of 3.5-4.4 kilograms, it is the smallest swan in the world. The feathers of its body are the same as the swan, but its head and neck are black, making it unique and unique. On its forehead, there is also a bright red large flesh crown called wart, which is very bright and developed. Its cheeks are red, its mouth is blue-gray, its mouth is gray-white, and its tarsomets and webs are pink.

What is the most devoted animal in the world? When it comes to the most loyal and devoted animals in the world, many people think of mandarin ducks. After all, they have always been representatives of beautiful love in folklore. In fact, mandarin ducks are inseparable only during the mating period, and once this period passes, they will have a new lover. In the animal kingdom, it is rare to have only one spouse throughout. Black-necked swans are one of the most single-minded animals in the world. They strictly implement monogamy. Many swans would rather die alone than find a spouse. Once they are married, the couple is very affectionate and couples. Together, they feed for food, rest, and play in the water together. They even take care of each other during the migration and never separate; if one unfortunately dies, the other will wail in depression all day long, preferring to be lonely rather than find another partner.

I like to live in swamps, lakes and lagoons with fresh or slightly salty water where aquatic plants such as cattail, banana grass, rush, reed, and duckweed live. The black-necked swan is also the only swan in the world that likes to swim with its young birds. It breeds in Paraguay, Uruguay, Chile, Argentina, Tierra del Fuego and the Falkland Islands in South America, and migrates north in winter until Paraguay and southern Brazil near the Tropic of Capricorn.

Black-necked swans are very caring for their families. Both sides raise their descendants together. All birds swim with their children, but only the black-necked swans carry their babies on their backs and love the cygnets very much.

Black-necked swans start breeding in July every year, but if the food is very abundant, some start from March to April. Under captive breeding conditions, individuals as young as 2 years old can be paired and bred, but later under natural conditions. The marriage proposal ceremony of black-necked swans is more intense than other swans, usually chasing opponents by lowering their heads and stretching their necks. After pairing, male and female birds live together, always inseparable from feeding, activities, etc., and then find a secluded place to nest together. Nesting begins as early as July, and populations distributed south do not start nesting until September. Nests are generally built on reeds or on small islands, and mainly use grass, branches, etc. as nest materials.

Each litter lays 4-8 eggs, which are cream-colored and have an average weight of about 220 grams. The incubation work is undertaken by the female bird alone, while the male bird is on guard near the nest. When the female bird leaves the nest for food, it will also temporarily hatch. The incubation period is approximately 34-39 days. Black-necked swans occasionally nest in groups, but due to the lack of enough food and nesting sites, fierce battles will occur, resulting in a low reduction in the average litter size and reproductive success rate.

The hatched chicks are early mature and are raised by the male and female birds. Since the adult birds move in the water almost all day long, the chicks lie on the back of the adult birds and follow the adult birds. The nestlings grow more slowly than other swans. Because the calories contained in food are very low, more nestlings and young birds die of malnutrition, such as bone distortions, and many individuals have parasites such as nematodes and flukes in their stomachs. The feathers of the young bird are brown-gray when they grow up, and turn to the color of the adult bird after a year, but the body is still relatively small and there is no crest on the forehead. Black-necked swans are sexually mature at 3-4 years old and have a life expectancy of 25-35 years.

The species has a wide distribution range and is not close to the critical value of vulnerability and endangerment for species survival (distribution area or fluctuation range is less than 20000 square kilometers, habitat quality, population size, and distribution area fragmentation). The population size trend is stable, so it is evaluated as a species without survival crisis.

Included in the World Union for Conservation of Nature (IUCN) 2012 Red List of Endangered Species ver3.1-Low-Risk (LC).

Included in Appendix II of CITES to the Washington Convention.

The goslings that have just hatched from black-necked swans are like domestic geese. The whole body of goslings is gray or white depending on the species. They can feed on their own, be raised by their parent geese, or they can be raised manually and raised in an incubator to keep warm. It is usually placed indoors after 2 weeks, spread fine sand on the ground, spread a layer of grass on it, and use electric lights or brooders to keep warm. The temperature was 31℃-34 ℃ in the first week, 28℃-30 ℃ in the second week, and 24℃-27 ℃ in the third week. After that, they were kept in an environment of 18℃-21 ℃

The feed for the goslings is steamed with mixed powder materials, as well as eggs, green feed, bone meal, calcium powder, cod liver oil, vitamins and trace elements. In the early stages of brooding, the environmental temperature is high, the feed is prone to deterioration, and the frequency of feeding should be increased, 4 times a day. In the future, as the goslings grew older and the environmental temperature decreased, the feeding frequency was gradually reduced.

In the artificial breeding of swans, in addition to paying attention to the adjustment of environmental temperature and feed, we must also do a good job in cleanliness and hygiene. Because the swan's feed is thin and soft, and the feed is often "thrown" when eating, the feathers and bedding are easy to get dirty, so the bedding must be changed frequently. When the ambient temperature is suitable, let the goslings take more baths 1-2 times a day, but be sure to guard them to prevent the goslings from drowning and dying. The daily bathing and swimming time depends on the physique and ability of the goslings, and can be gradually increased from half an hour to 1 hour. We must strive for the goslings to bask in more sun and exercise more. After a month of patient and meticulous care, the goslings will grow up healthily.

Its feed is divided into pellets, powder and green feed. Granules include corn, sorghum, rice or rice, and are regular feed. The powder material is barley residue (flour), corn residue (flour), sorghum (flour), soybean cake residue (flour), bran, fish meal (or silkworm chrysalis powder), bone meal, salt and various vitamins and minerals mixed, mixed and then fed (or steamed into wicks, and pressed into granules). Green forage includes various leafy vegetables, water plants, grass, etc.

Feed the powder once or twice a day (winter). Granules should be fed frequently, and added frequently and less. Feed large amounts of green forage in summer, which should be chopped and mixed into mixed forage, or thrown into water and allowed to eat freely. Appropriate amounts of vitamins should be supplemented in winter.

In daily management, for swans raised in groups, we must grasp the quality and quantity of feed, and pay attention to the cleanliness and environmental hygiene of food and drinking water utensils. For swans raised in pairs, the house should be cleaned every day to observe the swans 'feeding, defecation and behavior, and pay attention to whether there are abnormal changes.

Spring: When swans are raised in mixed groups, pay attention to whether there is any fighting phenomenon, and take immediate measures when this situation is discovered; nests and nests should be prepared in time to prepare for swan breeding; the proportion of protein feed should be increased during the breeding period.

Summer: Feed as much green forage as possible. Swans raised in mixed groups should pay attention to the hygiene of their feed, utensils and the cleanliness of water areas, and change drinking water in time.

Autumn and winter: Although swans born in northern China are not afraid of cold, they should also take certain measures in winter to prevent frostbite on their toes. For example, maintaining frozen water surfaces, laying thick grass on the ground, and adding wind protection and warmth facilities.

It mainly lives in the water. When swimming, its neck is bent and its head is lowered, and its posture is extremely elegant. When flying, the neck extends forward and the feet extend backward, and the wings flap slowly and forcefully. It mainly eats various aquatic plants, seaweed, algae and a small number of aquatic insects, fish eggs and crustaceans, etc. In some places, it mainly uses a certain kind of aquatic grass. When foraging, most of them choose open shallow water areas and constantly stick their heads and necks into the water to feed on the rich food on the water surface, but they rarely stand upside down in the water to feed.

Black-necked swans are less courageous and highly vigilant. After being startled, they chirped and flapped their wings to escape from the water. But in normal times, its cry is very weak, sounds like a gasp, and cannot travel far. In nature, the crested Kara eagle is its main natural enemy, often preying on its chicks and young birds or stealing eggs in its nest.

Black-necked swans like to live in groups, and sometimes they mix with swimming birds such as flat-billed geese, but the number of groups is not large. In the blue sky, they sometimes stretch their wings and soar and hover, and sometimes dive into the water like bullets from the bow, extremely light. When floating quietly on the lake, you look like a fairy, leisurely and contented, with a variety of postures, like a poem and a picturesque scene, which makes people feel dizzying and exciting. During the non-breeding period and dry season, thousands of black-necked swans can often be seen living together in clusters, often fighting with each other endlessly. When drought or the water level is too high, it is often done to disperse and migrate over a certain distance.
