Survival status and protection measures of birds

1. Protecting the natural environment on which birds live is the most fundamental and important measure to protect birds.

Bald-nosed crows are common birds in Beijing. 1In mid-October, the Women's No.3 Intermediate People's Court lived 1956 165438+2000 crows. 196 1 year165438+18 October ~ 65438+7 February, 234 crows were seen every hour on average, and more than 100 crows were gathered on a tree. When they got home, they discharged feces like rain, and the ground was full of rubbish. During the period of 1973, the Institute of Zoology of Chinese Academy of Sciences only saw more than 40 bald-nosed crows. After 1990s, bald-nosed crows were rarely seen in urban areas. This is the result of the rapid development of urban construction and the change of citizens' lifestyle.

2. In situ protection and ex situ protection, mainly in situ protection.

Establishing nature reserves is an effective measure for in-situ protection. In-situ conservation of crested ibis in Yangxian County, Shaanxi Province has achieved gratifying results. From 7 crested ibis found in 198 1, the natural population has now increased to hundreds.

Wild birds breed a large number of individuals under the conditions of artificial domestication and ex-situ protection, and then return to the natural environment to restore the endangered species population. However, it is difficult to succeed. For example, the United States tried to raise and breed passenger pigeons artificially, but it failed and eventually became extinct. The Japanese crested ibis was captured when there were only four in the wild, and the population could not be restored under artificial feeding conditions. Therefore, in order to protect those endangered birds, we should protect, restore and improve the environment of the original habitat in situ, and then strengthen other protective measures, so as to effectively protect the native birds and delay their extinction.

Step 3 save birds

Under normal circumstances, ordinary birds that are harmed in nature should not be concerned if they are not particularly rare and under the special protection of the state. Because in the natural ecosystem, all kinds of living things will be born and die, and there are complex food webs between living things, so everyone has to enter the natural cycle. Fragile individuals will eventually be eliminated naturally and become food and nutrition for other animals.

1In the winter of 999, Beijing successfully rescued four endangered species-oriental stork along the Chaobai River. That's because the specific situation of the local construction site at that time made the oriental stork lose the opportunity to migrate and was artificially fed under the condition of lack of food. It took them more than 1 month to recover their physique and return to the breeding ground in the north smoothly.

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

Strengthen environmental awareness, actively participate in greening and restoring the natural ecological environment, do not catch wild birds, and do not eat wild animals protected by the state, including wild birds. Consciously abide by the national laws and regulations on the protection of the environment, water, forests and wildlife. Consciously protecting the natural environment and caring for all life, including birds, is a manifestation of high civilization. Let's start from ourselves and create a green Olympics, a high-tech Olympics and a civilized Olympics.

First of all, the role of birds in forest protection and pest control can not be ignored. Many mountain birds often feed on insects, which is undoubtedly a good thing for forest trees. Because of this, woodpeckers also got the reputation of "forest doctor". In the 1970s, Yushan Mountain in Changshu was plagued by insect pests. Dendrolimus punctatus destroyed every pine tree on the mountain and turned the green hills halfway up the mountain into barren hills. People have tried various methods to control Dendrolimus punctatus (including manual control and spraying pesticides). ) to no avail, so biologists thought of the natural enemies of Dendrolimus punctatus and put forward a plan to control insects with birds. A few days later, a group of special "guests" came to the mountain. After this incident, who can look down on these grey magpies and stop treating birds as friends?

Second, only by providing a comfortable environment for birds can birds "live and work in peace and contentment". On chinanet, there is such a message; Bojiang Haizi in Ordos Plateau of Inner Mongolia is a paradise for world-class rare seagulls. Ordos Plateau in Inner Mongolia is a beautiful place, and we can raise seagulls. Besides, there is also a Shang Hu scenic spot in Changshu, Yushan National Forest Park, both of which belong to Taihu Lake scenic spot, with 18,000 mu of water and ten miles of green mountains and green waters. Shang Hu has clean water and is the only secondary water source in our city. Large-scale greening by the lake, unique geographical conditions and pleasant climate have created a comfortable living environment. Therefore, Taxodium ascendens planted in Fishing Beads and Hexiangzhou Park in recent two years has become a paradise for birds. Students found a large number of night herons, and made long-term observation, and found that night herons, which were originally winter migratory birds, actually appeared here all year round. The beautiful and comfortable environment in Yushan Shang Hu should be one of the important factors that make them change their habits.

Third, birds are more sensitive to climate and other environmental changes than humans. Therefore, caring about birds means caring about the living environment of human beings. Taking migratory birds migration as an example, migratory birds should follow a fixed route and migrate between breeding areas and wintering areas with different seasons. Night heron is a winter migratory bird in Changshu. It is its nature to fly in winter and breed in the north in spring. However, now some night herons have settled in Changshu and don't want to go home. On the one hand, it may be because of the comfortable geographical climate in Changshu. On the other hand, they may also perceive other problems. Maybe their hometown is no longer clean, maybe their migration road is no longer safe, maybe they think the temperature difference between north and south is not big. Therefore, there is no need to be too tired ... Also on the Chinese website, 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 the change of bird habits is one of the first serious consequences caused by climate warming.
