Birds on the Ground. Part Three
But this is the exception rather than the rule. After all, there are few flying mammals on Earth. Most of them are still ground creatures, unable to fly. You may object: but there are still butterflies, beetles, dragonflies, flies. True, however, they are still submissive to the air element, and not it to them. Insects are so light that even a faint breeze can change the direction of their flight. Some butterflies, however, like birds, make regular flights, but this is again an exceptional phenomenon.
Birds are mostly flying creatures. Only some species have lost the ability to fly — penguins, ostriches and some others. Scientists claim that birds descended from ancient reptiles that looked like crocodiles. Probably, intermediate creatures once lived on Earth, resembling both birds and reptiles? Yes, such birds were discovered by paleontologists — specialists in extinct animals. According to the bones found, it was possible to restore their appearance. They were similar to modern birds, but they had teeth, and on the wings — developed fingers with claws. They called these birds the first birds, or, scientifically, archaeopteryx. Archaeopteryx were heavy and, according to scientists, only fluttered from branch to branch. The most interesting thing is that nowadays there is a bird on Earth whose chicks have claws on their wings. It is called goatsin. Birds have conquered the ocean of air and settled around the globe. They are now found in forests and tundra, in the desert and in the mountains, on individual oceanic islands and even at the poles of the Earth. Over time, many different species of birds were formed — both large, such as the African ostrich, and very small, the size of a bumblebee, such as a hummingbird. Currently, according to scientists, about 8,600 species of birds live on Earth. The greatest species diversity of birds inhabits the equatorial forests. If you move from the equator to the poles, it will decrease. Scientists have registered the presence of 800 species of birds in our country. Human life has always been closely connected with birds. Man hunts them. Chicken, duck, goose, turkey, Japanese quail, he tamed and from time immemorial takes their eggs, feathers, fluff, and eats the birds themselves. Domestic pigeons were already in Egypt about 5 thousand years ago. They were used for communication and as decorative birds. Carrier pigeons were especially widely used during the wars. During one of the sieges of Paris, pigeons delivered about 150 thousand official dispatches.
Birds live in harmony with nature. They create forests, increase the germination of seeds. The "sowers" of birch and alder are siskins and tap dancers, bullfinches sow maple and ash seeds, bedbugs — coniferous trees, jay — oak, orekhovka settles cedar. Warblers help in the settlement of not only berry bushes, shrubs and semi-shrubs, but also trees. Man uses birds to fight insects and mouse-like rodents that eat crops in his fields, gardens and vegetable gardens. He builds birdhouses for them, hollows, and hangs feeders in winter. The benefits of birds are huge. And a wrongly ignorant idea of the role of birds can cause tangible harm to nature. It happens, of course, that birds themselves sometimes cause trouble to people: they destroy part of the harvest of grain crops, fruits, collide with airplanes, cause accidents on power lines, damage architectural and cultural monuments with their droppings, carry various diseases. However, if you think carefully, then in many of these cases people are to blame, not birds. In the future, we will try to dissociate ourselves from this and find ways out that suit both birds and people. In general, a person who has invaded nature causes birds much more inconvenience and trouble, often without suspecting it. And yet you will agree that life on Earth without birds would not be so beautiful. They delight us with their ringing songs, colorful outfits, clever tricks, and their cheerfulness. It happens that a person suddenly becomes sad or feels unimportant, then he will look at the cheerful sparrows, hear their joyful chirping and it becomes easier on his soul. Doctors even try to treat people with bird songs. Astronauts in spaceships, sailors on submarines are happy to listen to the sounds of the Earth, including the singing of birds, which lifts the mood, relieves fatigue.
