The egret has been included in the "Agreement between the Government of the People's Republic of China and the Government of Japan on the Protection of Migratory Birds and Their Habitat Environment". 》The little egret is the most common type of heron, usually referred to as the egret, and is a species on the list of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Yellow-billed egret and rock egret are both national second-level key protected animals. The yellow-billed egret is an internationally endangered species. The rock heron is one of 11 highly endangered birds in China. It is rare in China and is in an endangered state. The rock heron has been included in the schedule of the "Agreement between the Governments of the People's Republic of China and Australia on the Protection of Migratory Birds and Their Habitats". The yellow-billed egret is a new species collected by Robert Swinhoe (UK) in Xiamen in 1860. This species has been included in the "List of Terrestrial Wild Animals Protected by the State and Beneficial or of Important Economic and Scientific Research Value" issued by the State Forestry Administration on August 1, 2000. Growth and Reproduction The breeding period is from May to July every year. They nest on islands near the coast and on rocks at overhanging rocks on the coast or between short tree branches. They like to build nests together in groups. Someone once found 14 nests on the top of a hanging rock of only about 20 square meters, and on the top of an adjacent hanging rock of only more than 10 square meters. There are 11 nests on the top of the rock, and the distance between each nest is only 14 to 76 centimeters. In the past, there were also mixed groups of yellow-billed egrets, egrets, cattle egrets, night herons and herons nesting in Taiwan. Its nest has a shallow saucer shape and a relatively simple structure, mainly composed of withered grass stems and grass leaves. The nest is built on a dwarf tree, and the height from the ground is no more than 1 meter. Some nests are also built in the grass under a dwarf tree. Each clutch lays 2 to 4 eggs. The eggs are oval in shape and light blue in color. The incubation period is 24 to 26 days.
The yellow-billed egret used to be a common summer migratory bird along the southern coast of China, especially on the coast from Shantou, Guangdong to Fuzhou, Fujian. It was also seen in the Yalu River in Northeast China and Hunchun in eastern Jilin in the 1960s. In the early 1980s, it was seen in Liaodong Peninsula and There are more than 200 to 300 nesting pairs found on coastal islands, and large groups of dozens of them can often be seen foraging in the waters near the coast. However, due to environmental damage and human interference, especially because its pure white hairy feathers and cape feathers are extremely valuable ornaments and a large number are hunted every year, the population has declined significantly recently. As a result, its population has been declining and it has become very rare to see. According to the Asian midwinter waterbird surveys organized by the International Waterfowl Research Bureau in 1990 and 1992, only 143 were seen in my country in 1992, and 448 were seen in Southeast Asia. The Yellow-billed Egret has been listed in the Red Book of World Endangered Birds by the International Committee for the Protection of Birds (ICBP), and China has listed it as a national Level II protected animal.

What information is there about egrets?
Egret, genus Egret in the family Egretidae, order Storkidae. Also commonly called Little Egret, it is the city bird of Xiamen and an important wetland bird. It is the most numerous heron in Xiamen. Because of its high environmental requirements, it is an indicator of environmental quality. It is one of the most charming wetland ornamental birds. Pre-breeding period: Egrets will put on beautiful breeding feathers during the breeding period. Breeding feathers appear in spring and summer, so they are also called summer feathers. At this time, 2 braided feathers grow on the egret's head, slender feathers grow on the back of the neck, and there are rhododendron-shaped feathers on the back and chest. Exposed skin on the face will turn from yellow-green to pink. Nest area selection The functions of heron nest areas are mainly used for behavioral activities such as perching, mating, making nests, and feeding chicks. The selected nesting areas are generally located near wetlands, in woods, bamboo forests or shrubs with good vegetation coverage with little human interference. The islands better meet the above conditions, so many islands in Xiamen are breeding grounds for egrets. Xiamen is a coastal city where typhoons often pass through, and the winds on the islands are relatively strong. The nesting area chosen by the egret must also be sheltered from the wind to prevent typhoons from blowing eggs or chicks off the nest. In such an environment, they can safely give birth to children and reproduce. Before egrets enter the breeding grounds, they will inspect the nesting grounds. First, a few egrets flew to the island many times to visit the nesting site. They often circled over the woods where they had nested in previous years and then turned back. Sometimes they stayed on the treetops for a while. Then all the egrets resting on the tidal flats flew to hover over the woods. After this continued for a few days, a few egrets settled in a small patch of woods on the breeding ground. But then they moved to another or even multiple woods and finally settled down to breed. Then other egrets moved in in droves. Egrets like to breed in groups, with population sizes ranging from hundreds to tens of thousands. They can also nest and breed with other herons. In Xiamen, egrets, night herons, pond herons and cattle egrets mostly nest together to breed. Courtship and Mating: The egret immediately displays courtship and mating behavior after settling in. At this time, the time to fly away from the nest area to look for food is delayed, and the time to stay in the nest area is longer. Some individuals stay at the nesting site almost all day long. Here you can see heron groups active at the top of the canopy, often in pairs. Egrets often spread their back and chest feathers and tremble constantly. Sometimes egrets fly over the woods with branches in their mouths. There are also male and female individuals chasing among the branches and making bursts of chirping sounds. Individuals living in the same tree often compete for nesting branches. A fight breaks out. When the egret is mating, the male heron approaches the female heron. The male egret spreads its fluffy feathers and sings near the female egret, and then mates with the female egret's beak. After copulating 4-6 times, the male heron preens her feathers and "woos" her. The female heron crouched with her tail raised and flapped her wings. Finally, the male heron stood on the back of the female heron, bit her neck feathers with his beak, and kept flapping her wings while drooping. Then mating took place, each mating took about 20 seconds. After mating, the male heron stays near the female to rest. The female heron uses her beak to comb the feathers on both sides of her body and under her belly. Nesting: After entering the breeding season, egrets fly out to look for food later. A few individuals also stay at the breeding site during the day, gradually showing territorial behavior and occupying nest positions. When other individuals invade the territory, they will make a threatening sound of "ga-ga-" and at the same time have a confrontation with the intruding individual. The mouths are facing each other but there is no violent fight. This is a harmless intimidation behavior. Some times can last for more than 40 minutes. . The egret's nest is mainly built in the sunny shelter of thick branches. It is completely made of dead branches and is shaped like a basin. Egrets start nesting every morning and stop nesting in the evening. When the nest is first built, an egret flattens or breaks the branches around the selected tree branch (nesting branch) to sort out the nest site, and then breaks off dead branches nearby and spreads them on top. Another egret stands nearby, preening and alert. Once other individuals approach, they immediately stop building the nest, and the two parent birds jointly drive away the intruders. If there are unusual noises around or an eagle hovering in the sky during the nesting process, the two parent birds will immediately look up and sometimes fly away from the nesting branch, but they will fly back immediately. Of the two egrets, one is always resting and the other is building a nest. The nest material was broken from nearby dead branches. When first building a nest, it is difficult to place the first nest branch. Dead branches often fall from the tree, and the nesting bird then breaks off the dead branches and starts over. On the first day of nesting, usually only a few dead branches can be placed on the nesting branches. On the second day after nesting, the egrets began to carry branches from a distance. Carrying branches and building nests are carried out by two parent birds working together.
The egret holding a branch in its mouth picks up dead branches on the ground or breaks off dead branches from nearby trees. It holds the middle part of the branch, that is, the center of gravity. It first flies to the branch next to the nest, and then walks to the edge of the nest, using its beak to continuously open and close. The dead branch slides between the beaks until the center of gravity of the dead branch is exposed to the nesting egret. Nesting egrets stand on the nest and use their beaks to align with the rough center of the dead branches. After biting the dead branches, they often have to use the continuous opening and closing of their beaks to move the dead branches until they just bite the center of gravity. Nesting is done only during operation. In the early stages of nesting, the nesting speed and efficiency are low. When the nest is built to a certain height, the nest materials are easy to place and difficult to slip off. At this time, the two parent birds go out to carry the nest materials at the same time, greatly improving the speed and efficiency of nest building. The height of the nest from the ground is 2.4-7.2 meters, the outer diameter of the nest is 27-46 cm, the inner diameter of the nest is 19-37 cm, the height of the nest is 10-19 cm, and the depth of the nest is 2.5-7.4 cm. Nest building takes 3-6 days, and some eggs are laid before the nest is completely built. At this time, the egret's song changes significantly from the stage before it enters the breeding period, and the sound quality becomes thicker and makes a gurgling sound. In addition to carrying dead branches on the ground and breaking off dead branches from trees to use as nest materials, egrets also have the habit of picking up dead branches from old nests. There are also a few egrets that directly repair and reuse old nests. Egg laying and incubation Egrets begin to lay eggs when the nest is not fully formed. As the number of eggs increases, the nest continues to expand until the end of the incubation period. The fresh eggs of egrets are in the shape of duck egg blue and blunt oval, with an egg volume of about 24 mL and an egg weight of about 23 grams. There are 2-6 eggs in a clutch, usually 4-5. The egg-laying period of the parent bird is about 7 days, and eggs are basically laid every other day. During the egg-laying period, it is often seen that two adult birds appear in the field at the same time. One is mainly responsible for incubation and the other is nearby for vigilance. Both are responsible for driving away other individuals and continuing to build nests. They take turns. Incubation occurs, but the incubation is not focused. After laying all the eggs, the adult bird gradually hatches alone, and the other bird goes out to look for food. The time of sitting in the nest begins to increase, the number of leaving the nest gradually decreases, and the behavior of repairing the nest and turning over eggs is observed. During the incubation process, the egret's behavior of driving away other individuals is violent. When other egrets fly into the attack range, the behavior is no longer a confrontation but a violent direct attack on the opponent's body with the peak of its beak. However, this phenomenon occurs very rarely. Neighboring individuals do not easily approach the hatching nest. The incubation period is 24-25 days, and the hatching time of the whole nest is 3-6 days. Brooding Egret chicks are late adults. The newly hatched chick has a moist body, a small head, tightly closed eyes, and a large abdomen. The body is featherless except for the front neck, abdomen and under the intestines, which are covered with gray-white fetal down feathers. When the egrets are brooding, the parent egrets take turns flying out to look for food. The food they find is swallowed or held in their mouths first. After returning to the nest, they spit it into the mouths of the chicks or put it in the nest, and the chicks eat it by themselves. The parent birds fly in and out every day, sometimes up to more than 30 times. Until the chicks are able to fly away from the nest and go out to look for food with their parents. When the chick is 3 days old, it can hold the nest material tightly with its feet; when it is 5 days old, it can straighten its neck to peck food from the parent bird's mouth; when it is 9 days old, it can crawl in the nest; when it is 11 days old, its legs can not stand completely. At the age of 16 days, the legs can stand completely and can climb; at the age of 21 days, it can flap its wings and walk on the branches to leave the nest and snatch food from the parent birds; at the age of 26 days, it can fly short distances. The brooding period generally lasts 28-35 days. After a period of practice, when the young birds can fully master the skills of life in the wild, they will fly away from the breeding ground with their parents. Announces the end of the breeding season.
