We all know how pleasant it is to open your eyes in the morning, hearing the flooding voices of songbirds. It is they who are the first to call the sun, proclaiming the coming of a new day. Maybe for you it's cock crows in the village, where you spent your summer holidays with your grandmother. One way or another, bird singing accompanies us everywhere. It became habitual, sounding in the ears as a constant background. But having listened, everyone realizes how beautiful and simple the natural sounds of nature are. We will talk about this amusing chirping of birds.

Sounds of nature

Birdsong is considered one of the most peaceful and beautiful sounds in the world. Residents of big cities, in an effort to find peace and feed on the energy of nature, leave the stone jungle in order to hear it and fully relax. Fresh air and bird trills are one of the best ways to stop the running of thoughts and realize how beautiful the world around us is without its hectic rhythm and daily stress.

Birds, like other animals, transmit information to each other through sound signals. With their help, birds express the whole range of their inherent emotions, signal their relatives that danger awaits them. Even the hen, being an intellectually primitive bird, protects her chickens by sending them characteristic signals. According to them, the kids understand that it is necessary to leave an unfavorable place and hide in a shelter.

Singing and seasons

Birds do not need words to convey important data. To do this, they have a peculiar intonation, timbre and a voice inherent in each breed of individuals.

Trills of birds are well audible in spring and summer. This is due to the fact that during the period when the sun warms all living things, these creatures are taken to create their own families. In order to attract a female, males show all their advantages. In addition to external signs, they are distinguished by a special manner of inviting a potential partner with their voice.

The louder, more expressive and melodious it sounds, the more likely the male is to attract the attention of the female and fulfill the purpose laid down by nature. The instinct of reproduction is the main motivation of birds. We, as outside observers, simply enjoy this gift.

Tested and proven

Scientists conducted an experiment during which they isolated a chicken from all its relatives so that, growing up, they would not hear the sounds made by them. When the chick grew up, its sound signals were no different from the chickens that spent this time in the hen house. Experience has proven the fact that birds do not learn to sing (chirping, screaming). It's built into them genetically.

Moreover, some birds also reproduce the voices of their feathered relatives. In particular, we are talking about a mockingbird, for which he got his name. Another example is the canary. Once in the society of songbirds, for example, nightingales, after a while she acquires the skills of their singing. But the property of imitating a singing voice is not inherent in a sparrow. Another inimitable pretender among birds is a parrot. And although he is capable of learning human speech, imitating voice and timbre, he lacks awareness of what is being said.

Singers of our country

Russia covers vast territories and includes regions with different climatic conditions. In view of this, the variety of birds living in Russia is replete with unusual species.

Among the songbirds that live in the middle lane, there are those that evoke direct associations with our homeland.

Nightingale. Its iridescent trills inspire Russian poets and songwriters to create their masterpieces. A modest, outwardly inconspicuous bird, the nightingale has a unique and inimitable voice.

The singing of thrushes is akin to playing the flute.

The trills of the lark are heard in the morning, when it calls the sun and proclaims the beginning of the day.

Bright yellow orioles chirp, sing, whistle.

The robins chirp loudly and boisterously. No wonder in Rus' their trills are called raspberry ringing.

Other colorful singers of Russia: blackbird, siskin, goldfinch, chaffinch, mockingbird and others.

overseas birds

The vociferous birds of the world have been of interest and admiration to man since time immemorial. They inspire people and encourage the creation of musical instruments that imitate birdsong. But there is also a category of birds that do not sing, but talk. First of all, we are talking about parrots. These exotic birds surprise with their ability to reproduce the words and sounds of human speech. They live in Africa, Brazil, as well as on the exotic southern islands. The most talkative parrots on the planet are the Jaco parrots. They immaculately repeat not only words, but copy intonation, voice and speed of speech.

Another talkative bird is the European rook myna. Its peculiarity lies in the fact that it not only pronounces words, but actually inserts them in a dialogue with a person.

Another talented parodist is the warbler. She also reproduces the singing of other birds. It lives in the countries of the Old World, and flies to Africa for the winter.

Sleepless in the night

Some birds are nocturnal. With the onset of darkness, their activity increases significantly, because at this time the birds are looking for food. A prime example of this is owls. They fly silently, have keen eyesight and strike their prey at the most unexpected moment. We associate the peculiar hooting of an owl with a dense night forest and danger.

Other birds also respond at night. This is a nightingale, wild quail, warbler, redstart, blackbird.

Night trills pour during the mating season, namely in spring and summer. Mostly males sing. This is how they attract the attention of their potential partners.

The favorite habitat of night singers is places near water bodies and swamps. Their typical inhabitant is the marsh bittern. She makes very specific sounds, similar to a roar (bull).

City birds sing

Habitual inhabitants of the urban jungle are pigeons, swallows, crows, wagtails, magpies and sparrows. Their amusing but insipid chirping, cooing and croaking we hear all year round everywhere.

But with the onset of spring, the variety of voices and their melodiousness are greatly enhanced. The mating season in birds, as you know, is accompanied by singing. The trills of the nightingale, starling, song thrush, robin or chaffinch sound harmoniously in the city. Often these birds fly from the forest belt. In the city, they choose squares, parks and other places where there is vegetation. Therefore, if you want to enjoy the singing of birds and take a break from everyday hustle and bustle, go for a walk in a park or city garden. Such live concerts are held for the townspeople throughout the spring and summer.

whistling birds

Some representatives of the feathered world make sounds resembling a human whistle. It is heard in the forest, garden, park, both in spring and in the summer months. The characteristic sounds fit-fit, tick-tic-fuyu are made by the common redstart and its close relative, the black redstart. These small-sized birds from the flycatcher family are songbirds. They are considered one of the most beautiful birds living in city parks. The size of the bird is only 10-15 cm. The belly and tail of the bird are painted in a rich orange color. When she spreads her ponytail, it seems as if a real flame flares up.

We determine the bird by the manner of singing

Here are the exclamations characteristic of some birds by which they are recognized:

• sparrow: jik-jik-jik, chir-chir;
• raven: loud cries krok-krok, kru-kru;
• jackdaw: khee-khe, kaaa-kaaa;
• rook: kraaa;
• thrush: tsek-tsek, khii, keee;
• lark: tiu-tiu-tiu;
• warbler: chir-chir-chchrr;
• swallow: chirr-chirr;
• titmouse: ts-ts-tsy-prrr;
• jay: zhge-zhge;
• magpie: check-check-check;
• goldfinch: tsvi-tsvi-tsvik;
• wagtail: voiced intermittent chirping.

Sound Therapy: Birds and Children

The soothing sounds of nature deliver not only aesthetic pleasure. The trills of songbirds have a beneficial effect on the mental well-being of a person.

Listening to them calms, sets you up for a good rest and harmonizes from the inside. Children are especially sensitive to sounds and very impressionable. Therefore, it is important that from the first days the child is surrounded by the singing of birds.

The impact of the voices of songbirds occurs through their entry into the auditory zone, and then into the cerebral cortex and extends to it completely. When a baby (even a baby) hears bird singing, all his internal organs are tuned to harmonious and well-coordinated work. Audio recordings with bird calls are suitable for listening to a child before going to bed, and also if he is irritable, nervous or sad.

Birds are healing

Doctor of Biological Sciences Professor V.D. Ilyichev at one time conducted an experiment, during which a curious fact was revealed. People living outside the city and daily surrounding themselves with natural sounds, including birdsong, are more likely to be centenarians. This is explained by the fact that the natural sounds of rain, the rustle of leaves and bird singing are synchronized with the processes occurring in the body. It has been proven that certain bird voices solve very specific health problems.

The singing of the nightingale, accompanied by musical overtones with sharp and smooth transitions, uplifts the mood, fights migraines and depression.

Calm music with the chirping of a canary, thrush or finch has a beneficial effect on the state of the heart.

The singing of the lark uplifts the mood.

The singing of the blackbird is listened to for migraine and hypertension.

Principles of Sound Therapy

Nature shares its benefits with man and offers help. Subtly sensitive people use birdsong as an effective medicine that has no contraindications.

When you enter a park, forest, or other songbird habitat, step away from everything that worries you and listen carefully. Choose for yourself the sound of a bird that is especially pleasant to you and concentrate your attention on it. After a while, you will enter a light meditative state, and your energy background will stabilize and return to normal.

Listen to the songs of birds with pleasure every time, as soon as possible. After a while you will notice how you have become calm, balanced and cheerful. As for physical ailments, they will stop bothering you the way they used to.

To the question What is the name of the bird that makes the creaky cry "derg-derg" given by the author Maria Fedotko the best answer is dergach (corncrake)
Corncrake (dergach) is a bird that many hear, but few see. People also call him a jerk. On summer nights, the hoarse cry of the corncrake, diligently pronouncing its Latin name "crex-crex", is heard from the thick meadow grass. The bird itself hides all the time in thick grass.

Answer from Extra[guru]
This is a corncrake or dergach. Here is some information about this bird.
Corncrake, or dergach (lat. Crex crex) is a small bird of the shepherd family, belonging to the monotypic genus Crex.
Breeds in Europe and Asia, including Russia, where it lives in moist tall grass meadows, densely overgrown swamps, sown arable lands or not far from them. Migratory bird wintering in sub-Saharan Africa. Until recently, it was included in the list of the international Red Book as a species that is in danger of extinction, but in 2006, due to the clarification of the total number of birds, its status was improved and is currently considered as “close to the transition to the threatened group”.
Description
A small bird 22-25 cm long and weighing about 150 g. It resembles a chauffeur (Porzana porzana) in size and build - the same rounded body, slightly flattened from the sides, an elongated neck and a round head; however, it is distinguished from the latter by a noticeably shorter beak. The plumage of the upper body is light red, with dark streaks. The upper part of the head, primary flight feathers of the wings and tail feathers are chestnut with dark cores and gray endings. The sides are reddish-buffy, with white transverse stripes. The chin and front of the neck are light grey. The beak is short, strong, reddish-brown. The iris of the eyes is hazel or brown. The tail is very short. Legs brownish. Outwardly, males and females differ slightly from each other - the females have a goiter with an ocher-red tint, while the male has a grayer one. In winter, the gray tones of plumage are replaced by reddish-ocher. Does not form subspecies.
Flies reluctantly and slowly; in case of danger, it tries to flee, and when suddenly startled, it flies a short distance and lands, seeking shelter in dense vegetation. Among the tall grass, it moves quickly, often changing directions. In flight, unlike other birds, it does not stretch or tighten its legs, but leaves them dangling freely.
The voice is sharp and very loud (in good weather it can be heard at a distance of more than a kilometer) - a loud creaky "crack crack", reminiscent of the crackling of a wooden stick on the teeth of a comb. It calls mainly at dusk and at night, and only during the mating season - in spring and in the first half of summer. During a scream, he stretches his neck and periodically turns it in different directions - as a result, the voice is heard louder, then quieter. The cry of the corncrake is highly characteristic. It cannot be mixed with anything. It rarely turns into a quick “ge-ge-ge-ge” or “derg-derg-derg-derg” (hence the name), pronounced in a nasal and raspy voice.
area
Breeds in the forest and steppe zone of Europe and Asia to the west of the Baikal region and Vitim. On the territory of the Russian Federation, it rises north to 62-63 ° north latitude, in Scandinavia to 68 ° north latitude. In Asia, it is also found in Kazakhstan, Central Asia and Transcaucasia. In the Alps, it lives at an altitude of up to 1400 m above sea level, and in Russia it rises to the Alpine Sayan belt at an altitude of up to 3000 m above sea level. Previously, the range of the corncrake was much wider and covered most of Central and Northern Europe between 41 ° and 65 ° north latitude, and to the east reaching 120 ° east longitude. However, in recent years, its distribution, in particular in Western Europe, has sharply decreased and fragmented, and in countries such as Belgium, Denmark, Spain, Norway, Luxembourg, the Netherlands and Switzerland, it has become an extremely rare bird.
In winter, it migrates to savannah areas in central and southeast Africa between southern Tanzania and the northern regions of South Africa. Autumn migration begins in August and continues until the first half of October. Before departure, the birds are well gaining the weight they need for a long journey. Spring arrival at the end of April-May, when the grass is already quite high. They migrate alone and at night, so it is quite difficult to track the time of the flight.

Answer from super girl 023[newbie]
One of the options:
Great bittern (lat. Botaurus stellaris) is a bird of the heron family.
general characteristics
Bittern from the back has black feathers with yellowish rims, the head is the same color. The belly is buffy with a brown transverse pattern. The tail is yellow-brown with a blackish pattern. In general, this coloration of the bittern is camouflage and helps the bird go unnoticed among the reed and reed stalks where it lives. Males are somewhat larger than females. The body weight of the male is about 1 kg, sometimes up to 1.9 kg, height up to 70 cm and above, females are somewhat smaller. The wing length for males is on average 34 cm, for females 31 cm.
Spreading
The bittern breeds from Portugal east to Japan and Sakhalin. To the south, the range extends to Northwest Africa, Iran, Afghanistan and Korea. Another subspecies of the great bittern inhabits the southern parts of Africa. Bitterns winter in the Mediterranean, the Caucasus, northern India, Burma, and Southeast China. In some parts of Europe, bitterns do not fly away for the winter, but remain at the nesting site and live safely until spring. However, in severe winters, when all water bodies freeze, they die.
Lifestyle
The bittern arrives in Russia from wintering in early spring. Depending on the local climate, this may be March - May. Bitterns live in reservoirs with stagnant water or with a weak current, overgrown with reeds and reeds. The migration to the wintering grounds begins in late September-early October, however, some bitterns fly away already when the first snow falls. Both spring and autumn bitterns make seasonal flights alone. The bittern molt occurs once a year from August to January. Thus, molting ends already in wintering. The bittern is active at dusk. Like many herons, the bittern stands motionless for a long time, watching for prey, grabbing it with a sharp lightning movement. During the day, she stands motionless in the thickets, usually on one leg, with her head drawn in and ruffled. It is very difficult to notice it at this moment: it looks more like a bunch of dry reed stalks. In danger, she freezes with her neck extended vertically and her head raised. In this case, it is even more difficult to notice it, as it becomes like a reed, the beak, stretched upwards, resembles the head of a reed. In direct danger, the bittern opens its beak wide and regurgitates swallowed food.
Voice
The bittern has a very loud cry, spreading for 2-3 kilometers in the area. It can be conveyed as a low "tromb" or "u-tromb", reminiscent of a bull's roar. For this feature in Ukraine and Belarus, the bittern is called a bull. To some, the bittern's voice is reminiscent of the hum of the wind in a chimney. The bird makes such sounds with the help of the esophagus, which swells and acts as a resonator. Bittern usually calls in spring and in the first half of summer, usually at dusk and at night, as well as in the morning.
Nutrition
The bittern feeds mainly on various fish - crucians, tenches, perches, small pikes. also eat bitterns and frogs, newts, aquatic insects, worms, tadpoles. Sometimes they also catch small mammals. Bittern feeds chicks mainly on tadpoles.
reproduction
Bitterns begin to nest even in the same area very unevenly. The nest is arranged on hummocks protruding from the water, always in dense thickets. The diameter of the nest is about 50 cm, the height is about 35 cm. There are 3-7 eggs in a clutch. The female lays eggs with an interval of 2-3 days, but begins to incubate immediately after laying the first egg. The eggs are incubated mainly by the female, only occasionally replaced by the male. After 25-26 days, the chicks hatch. 2-3 weeks after hatching, the chicks begin to leave the nest, and at the age of 2 months they already know how to fly. Shortly after the bittern chicks fledge, the family breaks up.
