Coming into the woods or taking to the river, we enjoy the sounds of nature, most of which is provide a bird.They can sing, shout, whistle, hiss, without their diverse voices of these places do not seem to us so attractive.But what else is the meaning of the birds in nature and human life?How they are affected by proximity to the people?
Distribution of birds on the planet
Birds inhabit all continents and most populated of the islands.They settle wherever the vegetation grows, and there are living beings who will approach them for food.Their habitats - grasslands, forests, deserts, mountains, wetlands, tundra and steppes.There are also birds, which are most of the time in the open sea.According to some estimates, in the world there are more than 9,000 species of birds.The greatest variety of birds can be found in the tropical forests.The lowest number of species are in the Antarctic and the Arctic, where the conditions are too harsh.But it is home to a lot of individuals of a species.
benefit of birds
But what is the significance of birds in nature and human life, which requires such diversity?Interestingly, in each species has its own area of activity.All the birds are successfully meeting its mission due to the fact that their numbers are large.Scientists estimate that the planet is home to about 100 billion birds.Due to the fact that they eat insects and vegetation, they directly provide service to wildlife, preventing small creatures flood the Earth.For example, without them, the entire planet would be impassable because of huge clouds of insects.Also the value of birds in nature and human life is expressed in the fact that they eat small rodents, controlling their numbers.Without this, all the fruitful field is constantly exposed to the attack of pests.
also many birds serve as food for other animals, thereby maintaining a complex chain of the ecosystem.
Spread seeds
Many birds feed in winter and autumn fruits of mountain ash, wild cherry, elderberry, etc.As they travel from place to place, with the droppings, seeds that are watered by rain and germinate.Furthermore, poultry is transferred acorns that without them would remain permanently under the tree due to its gravity.For example, Jay grabbed the fruit of oak and carry them far, far away, but they often lose their flight - so sprout trees.
But the significance of birds in nature and human life does not end there.There are birds that feed on the nectar of flowers.For example, this hummingbirds and sunbirds, they fly up to the plant, and like many of his pollinating insects.
bird droppings down and
is worth noting some of the additional features of birds that bring benefit to man.So many kinds of litter is a real valuable fertilizer, but they Pooh is a good insulation for things.For example, sea ducks eider fluff famous low thermal conductivity, excellent softness and elasticity that is suitable for the manufacture of pillows and warm clothing.
bird droppings contain a lot of phosphorus and salts of nitrogen, which is considered an excellent combination to fertilize the soil.In those areas where the birds nest, sometimes you can find a thick layer of guano (droppings), which is used as fertilizer.
attract birds in parks
We found particularly birds and their importance in the ecosystem chain - they consume massive crop pests.Also important birds of prey, they massively catch small rodents that carry infectious diseases such as jaundice and plague.So if someone birds are found in the garden, they can not chase or scare.Also, do not keep on hunting them for sport.On the contrary, these tireless workers, it is important to involve in the parks and other places.The main thing - do not disturb populated nesting birds at the time and did not pick up chicks.You can make new plantations, so that the birds have places where they can hide.And in winter, you can help them, posting the feeder with seeds and bread.
disappearance of birds
Today, many species have become rare due to the fact that the man oppressed them with their progress and cruelty.Because of this, the birds of the Red Book are replenished with new titles.Today, established reserves where rare species can sense the relative safety without fear of human activity.
