198 1 year, the State Council, China approved the report on strengthening bird protection and implementing the Sino-Japanese agreement on the protection of migratory birds from eight departments, requiring all provinces, municipalities and autonomous regions to conscientiously implement it, and designated the week from March to April every year as "Bird Love Week", during which various publicity and education activities were carried out. Due to the vast territory of our country and the different climate between the north and the south, the time of bird-loving week varies from place to place.
Quanzhou generally designates the last week of March every year as Bird-loving Week. Birds are friends of human beings.
Now there are 902 1 species of birds in nature, and it is estimated that there are10 billion birds. Their eating habits are complex, their lifestyles are diverse, and they inhabit various ecological environments, which is an important factor to maintain the ecological balance of nature. As far as human interests are concerned, they are a group with great interests and little harm in the whole animal kingdom.
The most obvious benefit of birds is to eliminate pests. Most birds feed on insects, which are the natural enemies and nemesis of many pests in farmland and orchards. A white-faced chicken can peck 1800 caterpillars and eat 30 moths every day. European pink predators can also track locusts along the way. It has been calculated that 1000 purple-winged birds can kill 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 killing pests is really incalculable.
Birds have made great achievements in eliminating harmful animals, especially owls, eagles and other raptors. Most of them feed on rodents such as mice, which has made important contributions to controlling the spread of rodents and dangerous diseases in agriculture and forestry. 99% of owl's food is rodents. One owl kills mice in summer, which is equivalent to protecting 1 ton of grain.
Some birds that feed on plant seeds, especially geese and ducks, pigeons, 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, woodpeckers, rust-eyed birds, parrots, etc. Being addicted to nectar has obvious effect on pollination of flowering plants.
Without these birds, the ecological balance of nature will be destroyed. It can be seen that the role of birds in nature is almost everywhere.
Birds have made indelible contributions in the field of bionics: the inventions of airplanes and navigators are inspired by birds.
