Wild cormorants usually inhabit rivers and lakes and often fly low over the water. When flying, the neck and feet are straight. In summer, build a nest on a cliff or a tree near the water, or on a dwarf tree in a swamp lowland. Cormorants are not afraid of people. Often at the seaside, lakeside and fresh water. When resting, stand still on a stone or stump for a long time. Strong flying ability. In addition to the migration period, generally do not leave the waters. They mainly eat fish and crustaceans. When hunting, cormorants stick their heads into the water to track their prey. Cormorants' wings have evolved to help with paddling. Therefore, cormorants mainly swim with flippers in algae-infested waters, and use flippers and wings in clear waters or waters at the bottom of sand. In the water with low visibility, cormorants often sneak up on their prey, and then suddenly stretch their necks and make a fatal blow with their mouths. In this way, no matter how flexible the prey is, it will never escape. Cormorants can't see their prey clearly in the dim water. So you can only hit the target with keen hearing. Cormorants must surface to swallow after catching prey. Therefore, cormorants domesticated by fishermen can be seen in the rivers, lakes and seas in southern China and India to help fishermen catch fish. Fishermen will put a leather ring around the cormorant's neck before releasing it to prevent it from swallowing its prey. After catching the fish, the cormorant jumped on the fisherman's boat and spit out the fish in his mouth with the help of the fisherman. Cormorants are very greedy, and they will eat 3 Jin of fish all day long. A 35 cm long fish weighing half a catty can be swallowed in one gulp.

Common in southeast coastal provinces. Cormorants are widely distributed in rivers, lakes and oceans in Eurasia and Africa. The common people are the common cormorants in the river. There are actually many kinds of cormorants. Although they all belong to cormorants, they have their own characteristics in appearance and habits. Galapagos cormorants live in Galapagos Islands, and large cormorants are widely distributed in Asia and Africa, which are very distinctive species. The breeding cormorants can lay eggs normally under the condition of artificial domestication, and enter the breeding period in early summer every year. Each female bird can lay 6-20 eggs, and the breeding ecology is similar to that of domestic geese. During the breeding season, nests are built with branches or seaweed in cliffs, big trees or swamp bushes and reeds near the waters. 2 ~ 5 eggs per nest. A protein with a blue or light green luster. The incubation period is 28 days. Chickens are late bloomers. The parents store the caught fish in their throat bags, and the chicks stick their heads in and peck.

Editorial sections are distributed almost all over the world except the North and South Poles. There are five kinds of China: cormorants (also called common cormorants), spotted cormorants, sea cormorants, red-faced cormorants and black-necked cormorants. Common in southeast coastal provinces. Cormorants are widely distributed in rivers, lakes and oceans in Eurasia and Africa. The common people are the common cormorants in the river. There are actually many kinds of cormorants.

Galapagos cormorants live in Galapagos Islands, and large cormorants are widely distributed in Asia and Africa, which are very distinctive species. Edit the feeding methods in this paragraph. Cormorants in artificial domesticated environment like to live in sunny and ventilated environment besides fishing regularly every day. It is suitable for living in an environment without freezing. The feed is mainly small fish, Monopterus albus and pig intestines, and the daily feeding amount of each fish is 800 ~1500g. During molting, cormorants such as tofu brain should be properly fed, 300-400g each. Feed once every afternoon and rest on the perch after eating. Cormorants after a full meal are not suitable for sports and forced fishing. To domesticate cormorants for fishing, you can follow the fishing boat from the age of 60 and practice with the trained adult birds. After about 150 days of age, most domesticated cormorants can successfully master fishing skills. Cormorants that have been domesticated artificially for a long time have poor flying ability, and most individuals are not used to flying at high altitude for a long time, so they can skillfully identify cormorants in the same group or inhabiting fish boats. Cormorants used for fishing need to tie a ring around their necks with green rope or straw, or they can put a metal ring around their necks to prevent them from swallowing after fishing. Every time after fishing, the owner will take down the big fish he catches. You also need to feed the small fish as a reward to encourage them to go fishing again. To domesticate cormorants for fishing, it is necessary to fish in the water for 40-60 minutes on an empty stomach every morning, rest on the boat for 40-60 minutes after fishing, and then fish in the water. Generally, you can fish in the water three times a day 120 ~ 180 minutes, and cormorants bite their heads or cheeks more when fishing in the water. Usually, the weight of live fish caught alone is about 500 grams at a time, and up to 5000 grams of live fish can be caught alone. Fish over 5000 grams can also be caught. However, only a few or a dozen cormorants can cooperate with domesticated people to complete the capture task. According to relevant data, a group of more than a dozen cormorants once caught large mandarin fish weighing more than 15 kg. According to fishermen's experience, male cormorants are slightly larger than female cormorants, and their fishing ability is also stronger than female cormorants. Appropriate domesticated individuals can catch 15 ~ 25 kg of fresh fish per cormorant every day on average. If the waters and fish sources are ideal, there is also the best record of catching 35 kilograms per cormorant every day. Cormorant fishing can be used for over 10 years, and the fishing record is 28 years. The record of longevity can reach 40 years. Domesticated cormorants start courtship and mating every year 1 month, and most mating behaviors are carried out on the shore. One egg is laid every 1 ~ 2 days, and the eggshell is oval, turquoise or pure white. In a breeding period, a female bird lays 7 ~ 15 eggs, and the strongest individual is properly fed, with a record of laying as many as 40 ~ 50 eggs. The spawning time is generally 19:00-24:00. The weight of the egg is 48-59g, and the size of the egg is 39-4 1 mm× 62-66mm. Eggs are hatched by domestic chickens with nests for 26-28 days. Newborn chicks, with their eyes closed and naked, weigh about 40 grams and can open their eyes at the age of 3-4-7 days. Five days later, the furry chicken was born. Newborn chicks are artificially fed with minced fish and shrimp and porridge feed mixed with a small amount of tofu, each chick is fed 6-8 times a day, and the total feeding amount of each chick is about 50 grams per day; For 25-day-old chicks, the feed amount of each chick is increased to 250 ~ 360 grams per day. About 45 days old, with neat body feathers; Chickens aged 50-60 days can leave the nest independently and eat by themselves. Ugainvillii in South America and P. capensis on the southern coast of Africa are the most important producers of bird droppings. Cormorants are also called water crows and osprey. Birds. The body is longer and narrower than a duck, and its feathers are metallic black. It is good at diving and fishing, and flies in a straight line. In the south of China, more animals are raised to help fish. It belongs to Moraceae 1 genus with 30 species. Except for the north and south poles, it is almost all over the world. This kind of bird can be domesticated and fished, and it has been domesticated and utilized in ancient China. This is a common caged and free-range bird. Wild cormorants are distributed all over the country and breed in Northeast China, Inner Mongolia, Qinghai Lake and western Xinjiang. Edit this outline of cormorant meat taste with medicinal value: "sour and salty, cold and slightly toxic." Indications: 1. The original statement of Lei Gong's baking theory: treating cold abdomen. Cormorants burn and survive, and finally get drunk. (2) Outline: "Treating abdominal distension and benefiting waterways." It is advisable to avoid the "taste essentials": "pregnant women should not eat." Master's Compendium: "Cormorants, don't be idle, but Lei's" Baking Theory "preface says:" Cormorants are responsible for cold abdomen. "I think abdominal distension is hot, and Wei Qi is parallel to blood vessels, so the body is cold. This is a water bird. Its air is cold, but it is good for water. Cold can overcome heat, and water can eliminate dampness, so it is also good. " Its function is mainly diuresis. Indications: edema. After editing this news report, it is difficult to see cormorants again. Do you still remember the article "Cormorants" written by Mr. Zheng Zhenduo in the primary school textbook? As long as the fisherman stands up and puts a penny on the side of the boat, the cormorants will flap their wings and dive into the water. However, such a beautiful artistic conception can no longer be seen. Cormorants are forbidden to be used as water fishing tools because of their unique fishing skills. Fujian Marine Fisheries Bureau issued a notice on June 5438+1October 65438+February, 2006, officially implementing the fishing method Catalogue of Fishing Gear Prohibited and Restricted in Fujian Province, which included fishing gear fishing method and original fishing gear including cormorants in the scope of prohibition or restriction.

Editing this cultural story In many parts of our country, people call cormorants niggers to describe this kind of bird, which is not as stupid as boobies, but has superb fishing skills. Cormorants are very popular in fishing in China. Some people have domesticated cormorants for a long time and used them for fishing. In the southern water town, fishermen often take domesticated cormorants with them when they go fishing. Cormorants stand neatly at the bow, with collars on each neck. When fishermen find fish, they whistle and cormorants jump into the water to fish. Because of the collar, the cormorant caught the fish but couldn't swallow it, so it had to return to the boat with the fish in it. After the owner took the fish, the cormorant dived into the water to fish again. When you meet a big fish, several cormorants will catch it together. Some of them peck at the fish's eyes, some bite the fish's tail, and some bite the fish's fins. They cooperate well. After fishing, the owner took off the cormorant's collar and gave them the prepared small fish to eat. This fishing method is very interesting and effective. Therefore, cormorant fishing was once very popular. Du Fu once wrote such a poem: "Domestic niggers eat yellow croaker every meal". The popularity of this fishing method at that time can be seen. Of course, this ancient fishing method can only meet the self-sufficient small production economy, and it is rarely used in modern times. In fact, too many cormorants will do great harm to fishery production. According to statistics, wild cormorants eat at least 400 grams of fish every day. In Holland, a group of cormorants ate 5000 tons of fish in one summer. Cormorants are not only experts in fishing, but also often used it as a symbol of happy marriage in ancient times. Cormorants live together in harmony and take care of each other, from nesting to brooding. The well-known first poem in The Book of Songs is "Guan Guan's pheasant dove is in the river continent". Some scholars believe that the pheasant dove in the poem is a cormorant. Of course, whether pigeons are cormorants or not, the close and friendly relationship between cormorants can represent a beautiful marriage. Cormorant plague disease name.
