Birds are friends of human beings

There are 921 species of birds in nature, with an estimated 1 billion birds. Their eating habits are complex, their lifestyles are diverse, and they inhabit various ecological environments, which is an important factor in maintaining the ecological balance of nature. As far as human interests are concerned, they are a group with great benefits and little harm in the whole animal kingdom.

the most obvious benefit of birds is to kill pests. Most birds feed on insects, which are the natural enemies and nemesis of many pests in farmland and orchards. A chick with a white face can peck at 18 caterpillars and eat 3 moths every day; European pink predators can also track locusts along the way. It has been calculated that 1, purple-winged birds can wipe out 22 tons of locusts during the breeding period. There are thousands of insect-eating birds in nature, and the insects they prey on are very different, so its role in eliminating pests is really difficult to estimate.

Birds have made great achievements in killing harmful animals, especially birds of prey such as owls and eagles, which mostly feed on rodents such as mice, and have made important contributions to controlling rodents in agriculture and forestry and the spread of dangerous diseases. 99% of the owl's food is rodents, and an owl kills mice in a summer, which is equivalent to protecting 1 ton of food.

Some birds that feed on plant seeds, especially geese and ducks, doves, woodpeckers and crows, are effective spreaders of plant seeds, and many plant seeds germinate more easily after passing through the digestive tract of birds. Hummingbirds, hummingbirds, sunbirds, flower peckers, rusty-eyed birds, parrots, etc. are addicted to nectar and have obvious effects on pollination of flowering plants.

without these birds, the ecological balance of nature would be disturbed. It can be seen that the role of birds in nature is almost ubiquitous.

Birds have made indelible contributions in the field of bionics: the inventions of airplanes and navigators all came from the inspiration of birds.

The survival of birds is threatened

According to archaeological research, there may have been 1.6 million species of birds on the earth in the Cenozoic era 7 million years ago. Later, due to crustal changes and glacier movement, the number of birds dropped sharply. Up to now, there are only over 9, species left on the earth, and their situation is also very worrying. With the large-scale exploitation of nature by human beings, it poses a great threat to the survival of birds. Forests are places where birds live, and destroying forests is equivalent to killing birds. However, at present, the forests on the earth are still decreasing at the rate of 11 million hectares per year, which makes many birds lose their living environment. American passenger pigeons, extinct in the early 2th century, were once so numerous as to cover the sky in the 19th century. By the end of the 19th century, the oak forest where American passenger pigeons lived was severely damaged, and as a result, this bird soon became extinct. According to the survey data of former West Germany, in the past 5 years, 73 species of birds and other animals have become extinct, 18 species of birds have died in large numbers, and some are approaching extinction.

The beach on the river bank and the pond on the branch of the lake are good habitats and breeding places for many kinds of birds. Inappropriate land reclamation and land reclamation around the lake have destroyed the living environment of wading birds and swimming birds. The disappearance of wetlands has caused many waterfowl to lose their habitat.

Environmental pollution and man-made killing also do great harm to birds.

protection of birds, human knowledge

the decline of birds will ultimately hurt human beings themselves. In order to change the situation that birds are decreasing day by day and many rare birds are on the verge of extinction, many countries in the world have taken corresponding measures, formulated laws and regulations, and concluded more than 4 international agreements and conventions on the protection of birds, such as the Convention on Wetlands of International Importance, especially as Waterfowl Habitat, and the Convention on the Protection of Migratory Species of Wild Animals. Many academic organizations have been established, such as the World Wildlife Fund (WWF) headquartered in Switzerland, the International Waterfowl Research Bureau (IWRB) headquartered in Britain, the International Council for the Protection of Birds (ICBP) and the International Crane Foundation (ICF) headquartered in the United States.

In order to publicize and care for birds, many countries have chosen birds with symbolic meaning as "national birds". For example:

America-bald eagle Japan-green pheasant India-blue peacock

Myanmar-peacock Iraq-eagle Philippines-Philippine eagle

Germany-stork Netherlands-egret Denmark-lark, White swan

Norway-river bird Sweden-Ukraine bird Iceland-white falcon

Austria-domestic swallow Poland-eagle Zambia-eagle

South Africa-blue crane Argentina-brown-oven bird Australia-qinbird

Estonia-domestic swallow

At present, bird nature reserves have been established in China.

Bird Island Nature Reserve in Qinghai Lake established in p>1975 (53,55 hectares);

Heilongjiang Longbaotan Black-necked Crane Reserve (1, hectares) was established in p>1984;

Xinjiang Bayinbuluke Swan Reserve (1, hectares) established in p>198;

Poyang Lake wintering migratory bird reserve (22,4 hectares) was established in p>1984;

In July, 1983, the first bird ecological protection zone was established in Guandu, Zhongxing Bridge and Huajiangqiao sections at the junction of Taipei City and Taipei County. There are more than 17 species of birds protected in the protection zone, accounting for 42% of the total number of existing birds in Taiwan Province.

birds are so important and lovely. People who love birds, such as us, should take practical actions to protect birds, not to harm them, and not to enjoy wild birds.
