The survival status and protection measures of birds

1. Protecting the natural environment that birds rely on for survival is the most fundamental and important measure to protect birds.

The bald-nosed crow is a common bird in Beijing. In mid-November 1956, more than 2,000 crows roosted in the courtyard of the No. 3 Women's Middle School. From November 8 to December 7, 1961, an average of 234 bald-nosed crows were seen per hour, with more than a hundred crows gathering in one tree. When they returned home, they excreted feces like rain, which covered the ground in an instant. In 1973, when the Institute of Zoology of the Chinese Academy of Sciences conducted a census of bald-nosed crows, only about 40 were found. After the 1990s, bald-nosed crows are almost no longer seen in urban areas. This is due to the rapid development of urban construction and changes in citizens' lifestyles.

2. In-situ protection and ex-situ protection, with in-situ protection being the main one.

Establishing nature reserves is an effective measure for in-situ conservation. The in-situ conservation of crested ibises in Yangxian County, Shaanxi Province has achieved gratifying results. From 7 individuals when they were discovered in 1981, the natural population has now grown to hundreds.

Wild birds are artificially domesticated and bred, and protected in ex-situ, to breed a large number of individuals, and then released into the natural environment to restore the population of endangered species. But it is difficult to succeed. For example, the United States tried to breed passenger pigeons in captivity, but failed, and eventually became extinct; Japan's crested ibis was captured when there were only 4 left in the wild, and attempts were made to restore the population under artificial breeding conditions. Also failed. Therefore, if we want to protect those endangered birds, we should protect them in situ, restore and improve the environment of their original habitats, and strengthen other protection measures. Only in this way can we effectively protect the original birds and delay their extinction.

3. Rescue of birds

Under normal circumstances, ordinary birds that encounter injuries and illnesses in nature should be left alone unless they are particularly rare or nationally protected birds. . Because in the natural ecosystem, all kinds of creatures will be born, old, sick and die, and there are complex food webs among creatures, and every individual must enter the natural cycle. Weak individuals will eventually be eliminated naturally and become food and nutrition for other animals.

In the winter of 1999, Beijing successfully rescued four endangered Oriental white storks on the banks of the Chaobai River. That's because the specific conditions at the local construction site at that time caused the Oriental White Storks to lose the opportunity to migrate and lacked food, so they fed food artificially. It took more than a month for them to recover and successfully return to their breeding grounds in the north.

4. Raising awareness of bird protection and strengthening protection measures are important guarantees for bird protection.

Strengthen awareness of environmental protection, actively participate in greening and restoring the natural ecological environment, do not capture wild birds, and do not eat nationally protected wild animals including wild birds. Consciously abide by various national laws and regulations regarding the protection of the environment, water, forests, and wildlife. Consciously protecting the natural environment and caring for all life, including birds, are manifestations of a high degree of civilization. Let us start from ourselves and create a green Olympics, a technological Olympics, and a civilized Olympics.

First of all, the role of birds in protecting forests and preventing pests cannot be ignored. Many mountain birds often feed on insects, which is undoubtedly a good thing for forest trees. For this reason, woodpeckers have also gained the reputation of "forest doctor". In the 1970s, there was an insect disaster in Yushan, Changshu. Pine caterpillars destroyed every pine tree on the mountain, turning the green hills half into the city into barren hills. People used various methods to control pine caterpillars (including manual pest control, spraying pesticides, etc.) All to no avail, so the biological experts thought of the gray magpie, the natural enemy of the pine caterpillars, and proposed a plan to control the pests with birds. A few days later, a group of special "guests" came to the mountains. This was a group of birds specially designed to deal with pine caterpillars. Sure enough, After a period of time, pine caterpillars were significantly reduced in some areas, and new leaves could be seen on the pine branches. After this incident, who can underestimate these gray magpies? Who can not regard birds as friends?

Second, only by providing a comfortable environment for birds can birds "live and work in peace and contentment." There is a piece of news on China.com: Bojiang Haizi on the Ordos Plateau in Inner Mongolia is a paradise for world-class rare gulls. The Ordos Plateau in Inner Mongolia is a beautiful place, so we can keep the relict gulls. Besides, we have a Shanghu Lake Scenic Area in Changshu, which is part of the Taihu Lake Scenic Area and Yushan National Forest Park. The 18,000-acre water area and the ten miles of green mountains and rivers complement each other. The water quality of Shanghu Lake is clean and it is the only secondary water source in our city. The large area of ??greening around the lake, unique geographical conditions and pleasant climate create a comfortable living environment.

Therefore, the pond cedar forests planted in Diaouzhu and Hexiangzhou parks in the past two years have become a paradise for birds. The students discovered a large number of night herons and made long-term observations. They found that night herons, originally winter migratory birds, appear here all year round. The beautiful and comfortable environment of Yushan Shang Lake should be one of the important factors that make them change their habits.

Third, birds are more sensitive to changes in climate and other environments than humans. Therefore, caring about birds means caring about humans’ own living environment. Take the migration of migratory birds as an example. Migratory birds should move between breeding areas and wintering areas along fixed routes according to different seasons. The night heron is a winter migratory bird in Changshu. It flies to overwinter in winter and goes north to breed in spring. However, some night herons have settled in Changshu now and do not want to return. On the one hand, it may be because of Changshu’s geography and climate. The environment is comfortable, but on the other hand, they may also be aware of some other problems. Maybe their hometown is no longer clean, maybe their migration route is no longer safe, or maybe they feel that the temperature difference between the north and the south is not big, so they don’t need to work too hard... ...also on China.com, there is such a message: "Spring River Plumbing Duck Prophet". Some French bird protection experts believe that animals are more sensitive to climate change than humans, and changes in bird habits are the first serious consequences of climate warming. one.
