In the spring, males acquire bright outfits, perform calling trills and roulades, dance pirouettes, and fight with rivals. And all this in order to attract the attention of the female and continue her race. The criteria for choosing a partner are different for all birds: it can be the strongest, the most motley, loud-mouthed, caring or the most hardworking. Relationships in bird couples can be either short-lived or long-lasting, sometimes for several seasons, sometimes for a lifetime.

Birds, like other land animals, are characterized by internal fertilization. The male throws sperm into the female's genital opening, the sperm reach the mature eggs inside the ovaries and fertilize them.

Interestingly, birds have paired reproductive organs and reproductive tracts, but in most species only the left “halves” are used for reproduction. It is possible that the simultaneous formation of large eggs in paired ovaries is simply impossible. As for males, outside the mating season they are usually sterile, but in the spring their testes can increase in volume by almost a thousand times.

The male's sperm enters the female's genital opening at the bottom of the oviduct system. From there it moves into the oviduct, where in some cases it can remain for several weeks before being used to fertilize the egg. Direct fertilization occurs in the initial part of the oviduct.

After this, the egg moves towards the cloaca, “overgrown” with membranes, and finally, in the thickened posterior section (uterus), just before flowing into the cloaca, a calcareous shell protection is formed.

How does mating work?

Birds do not have a special genital opening; their reproductive tract exits into the cloaca - the terminal section digestive system birds Mating itself consists of the fact that the male presses the outlet of his cloaca against the outlet of the female’s cloaca (the so-called cloacal kiss) and transfers his sperm to her.

Only in a few species, in particular in ostriches and some ducks and geese, males have a special copulatory organ in the form of an unpaired eversible section of the cloaca wall, which enters the genital opening of the female during mating.

In male Argentine ducks, this organ can be one and a half times the length of the duck itself, reaching 45 cm. A reasonable question arises: where is so much? Doesn’t he curl up in a ball in the female’s body during the mating process? That's right, it doesn't wrap. And from a “technical” point of view, the size of the reproductive organ of these amazing birds is completely excessive. And they grew it for themselves to show off.

Other animals, including humans, use symbols to outmaneuver their rivals in mating games: a peacock fluffs its tail, a dove puffs up to appear larger, a dolphin dances, and a man showers his lady with gifts. Argentine warblers "decided" to simplify the scheme by using the penis itself as a symbol of the penis.

Birds are a special class in the progressive branch of the animal world. It is reliably known that they owe their origin to reptiles, but unlike them they managed to learn to fly.

I wonder how birds mate? The subtleties and features of the process will be highlighted in the article.

General characteristics

Before we talk about how birds mate and reproduce, let's discuss their characteristics and the biology of this class of warm-blooded oviparous birds.

The distinctive features of birds are as follows:

• The nervous system is highly developed.
• Various options for adaptive behavior.
• The body has high temperature. This occurs due to the intensive metabolism of the bird class.
• Compared to other animal species, this species is endowed with a special mechanism that facilitates the rapid reproduction process. This feature is manifested in the ability to hatch eggs, as well as in feeding chicks.
• The presence of special organs called adaptive. They make it possible not only to fly, but also to move freely on land. And some individuals can also swim in bodies of water, moving freely along the water surface.

It is these above-mentioned abilities that allow birds to reproduce so actively and massively throughout the planet.

Males

Let's talk about the reproductive system of males of this class of animals.

Each male has testes. They resemble ordinary beans and are located above the buds.

The testes are suspended on the so-called mesenteries. The size of the bean-shaped bodies constantly changes throughout the year. When it's time to reproduce, they increase in size.

For example, in the Zyablik family, the testes can grow as much as 1125 times, and in a simple yard starling - 1500 times.

The inner part of the genital organs of birds has appendages attached to them. It is from them that the vas deferens diverge. They run along the urinary system, go around the ureter and go straight into the cloaca.

In nature, there are also birds whose vas deferens resemble small dilators, they are called bubbles. They serve as special reservoirs in which seminal fluid and sperm are located.

But not every class of birds has a copulatory organ (penis). In those who do not have it, its function is performed by the protruding cloaca.

A similar organ was noted in ostriches, anseriformes, and also in tinamous. But in storks, long-legged herons and birds called bustards, the copulatory organ is considered a rudiment.

To the question of how birds mate, we will answer that in most representatives there is maximum closeness of the cloacae. That is, the female’s cloaca approaches the corresponding organ of the male at the moment when sperm is released.

Females

A feature that distinguishes the reproductive system in females of this class is that for the most part it is represented only by the left ovary, as well as the left oviduct.

The ovary, located on the right, is present only in some birds. These include loons, owls, gallinaceae, parakeets, rails and some of the birds of prey. But even the presence of this gland does not mean that it will function. This happens extremely rarely.

Reasons for asymmetry

It lies in the fact that females lay fairly large eggs with a dense shell. They move along the oviduct for a long time, approximately two days. But the ovary itself in females has an irregular shape with a granular medium. It is located in front of the kidney. The size of the ovary is directly affected by the size of the egg in it. The oviduct itself resembles a long tube, and the ripe egg moves along it.

Sections of the female oviduct

The oviduct, on one side, is connected to the cloaca, and on the other, to the body of the bird. It consists of a couple of compartments. The first contains special glands that secrete protein. The egg stays here for about six hours, where it is covered with a special protective layer.

In the second section it is thinner; the shell membranes begin to cover the egg.

Another section is the uterus. The egg comes here for 20 hours. During this time, it begins to be covered with lime shells, as well as other coloring pigments.

And the last section. It's called the vagina. It is from here that the egg ends up in the cloaca and then comes out. The time it takes for an egg to “travel” through the oviduct is on average 24 hours. It's from the chicken. But the dove’s is already longer, 41 hours.

How do birds mate? Features of reproduction

In general, the reproductive pattern of most birds is similar. But still, each species has individual characteristics and characteristics.

Let's take a closer look at the features of mating using the example of hens and cockerels. Although it is worth noting that representatives of this bird species are able to lay eggs without a male.

What does it mean? And the fact that the egg that comes out will be unfertilized. In males, at a certain period, the testes begin to actively work, that is, to increase in size. During this period, roosters are ready for active mating. It is at this moment that the transfer of genetic material to the female individual occurs. After a certain period of time, the female begins to lay eggs. Their number in different classes is completely different, and reproduction in the order of birds occurs at different times, because the biology of each species is very diverse.

Let’s say that some individuals are already ready to reproduce and have offspring in the spring, while others will wait until mid-summer, and only then will they lay eggs to hatch chicks.

Everything happens for the reason that some birds love to travel, roam around different countries, and only during the breeding season begin to nest. Others lead a sedentary life and always nest in the same familiar place.

In order to better understand the mating process of each representative of this class, you will have to study individual characteristics the bird of interest, the structure of its reproductive system, the behavior of the male during the mating season, the characteristics of the whole organism and other characteristics.

Determining the male's readiness to mate

How to determine whether a male is ready to procreate or not? This is quite easy to understand from his behavior, because it is he who takes the initiative with his “wings” and begins to care for the female.

It is enough just to observe some representatives, and it will immediately become clear whether he is ready for family life, or else wants to take a walk.

How do birds mate? You can see photos of males courting females in the article. The feathered suitor will devote all his strength to courting the female. He will fluff his tail, preen his feathers and begin his attack. The courtship will last until his passion gives up.

For example, parrots playfully knock with their beaks, begin to jump around the chosen one, feed the female, and also present her with all sorts of gifts. They try with everything possible ways make an impression.

Some males are quite smart and put a lot of effort into outrunning their rivals. Various methods are used for this. Let’s say peacocks open their bright tail, bursting with colors, and pigeons swell, stick out their chests so that they seem large, a dolphin begins to dance and amaze the lady with a playful dance. But the Argentine ducks went the furthest. They simply show the female their male organ, and she chooses the most suitable one from the offered assortment of genitals.

Instead of an afterword

Now you know how birds mate. The process is very curious and fascinating, and each individual has its own, special, unique process. One has only to pay attention to the world that surrounds us. After all, so many unusual and wonderful things happen there.

Of all representatives of the fauna, birds have the most complex process of courtship and mating - the so-called mating games.

In the spring, males acquire bright outfits, perform calling trills and roulades, dance pirouettes, and fight with rivals.

And all this in order to attract the attention of the female and continue her race.

The criteria for choosing a partner are different for all birds: it can be the strongest, the most motley, loud-mouthed, caring or the most hardworking. Relationships in bird couples can be either short-lived or long-lasting, sometimes for several seasons, sometimes for a lifetime.

Birds, like other land animals, are characterized by internal fertilization. The male throws sperm into the female's genital opening, the sperm reach the mature eggs inside the ovaries and fertilize them.

Interestingly, birds have paired reproductive organs and reproductive tracts, but in most species only the left “halves” are used for reproduction.

Argentine warblers "decided" to simplify the scheme by using the penis itself as a symbol of the penis. Looking at the offered assortment of genitalia during mating games, the female chooses the most suitable partner for herself - and voila!

Birds, like other land inhabitants, are endowed with the function of internal fertilization. Males choose a female, inseminate her through the genital opening, the ejected sperm reach mature eggs in the female’s ovaries and fertilize them. During the extramarriage period, males are sterile, but in the spring their testes enlarge hundreds of times.

In females, only one ovary is developed, the left one. It is located on the mesentery near the anterior end of the left kidney. The Müllerian canal or left oviduct opens as a funnel into the body cavity of the ovary, and its thickened uterine section, which is located behind, flows into the cloaca. Some females are characterized by a blind outgrowth of the cloaca (the remnant of the right reduced oviduct). Some of the follicles increase at the beginning of reproduction, because the oocytes that are in them rapidly accumulate yolk; At the same time, the oviduct lengthens and its walls swell. The wall of the follicle ruptures, the egg falls into the body cavity and enters the oviduct.

Fertilization occurs in the oviduct. The egg moves to the cloaca and is covered with several secretions of the glands of the walls of the oviduct, which form a shell for it. From the moment the egg enters the oviduct, the complete formation of the egg and its preparation for laying occurs from 12 to 48 hours.

Birds begin to mate in a specific season of the year for each species, because... this affects the growth and feeding of chicks (in northern latitudes in May-July; in the tropics in cooler, rainy times, and for piscivorous species, on the contrary, during periods of drought).

Manifestations of mating in birds are unusually diverse, for example, the sonorous song of a sparrow, the dancing of cranes, the cries of owls, etc., these are a kind of mating games. This can also occur during current contact. Current phenomena organize the meeting of a female and a male, facilitating the formation of a pair, so to speak, providing physiological preparation before mating.

Mating of birds occurs at the moment when the male presses against the female's cloaca with the exit of his cloaca, through which sperm is transmitted; the so-called “cloacal kiss” occurs. And only the males of some species of birds (ostriches, geese, ducks) have a copulatory organ, which looks like an eversible part of the cloaca, helping to penetrate the female’s opening intended for fertilization.

For fertilization and further egg laying the following set of factors has been identified:

• favorable temperature;
• required amount stern;
• availability of nesting space;
• presence of a male.

Preparing birds for breeding

Already with current contact birds begin to build a nest to reproduce. In most cases, the female participates in its formation; she carefully lays out the materials that the male brings. The nature of nests is very diverse; some birds have more similar ecological features. There are also birds that lay their eggs on the ground, covering the hatching site (hole) with branches (waders, guillemots, nightjars, chickens, owls, etc.). Female geese and ducks pluck fluff from their abdomens, which they additionally use to line the nest.

Sparrows are real masters in nest building. A dense bowl made of dry thin twigs, the inside is covered with moss, soft selected wool, feathers and stems.

Nests protect brooding birds and chicks from various predators and adverse weather. In them, females hatch eggs, and males protect their family from possible danger. In brooding females, the feathers on the abdomen fall out, thus forming in this place "brood spot". There are about 2 or 3 such spots. As a rule, their presence indicates good heating of the eggs and a laying temperature of approximately 38 degrees. “Roost spots” are not formed only in Anseriformes, because their nest is lined with a lot of fluff.

Birds incubate eggs more intensively after all eggs have been laid, so the chicks hatch almost simultaneously. During the development of the embryo, the salts contained in the shell gradually move to the skeleton, which is why the shell becomes fragile and the formed chick hatches easily.

Incubation time

Hatching duration depends on the following indicators:

• type and size of female;
• type of nest;
• egg size;
• incubation intensity.

Passerines incubate eggs from 11 to 14 days; crow - 17 days, slightly larger crows - up to 22 days, mallards - 26 days, swans - from 35 to 40 days, etc. The longest incubation period for vultures, albatrosses and large penguins is up to 2 months.

How do pigeons reproduce?

Breeding pigeons is a fairly common question that many amateur pigeon breeders are interested in, because the health of the offspring and the production of new breeds depend on the success of the breeding process of this type of bird. To achieve a good result, it is necessary to take into account the characteristics of mating and the conditions necessary for the life of pigeons.

Features of mating pigeons

There are two types of mating:

1. Natural (the male chooses the female himself);
2. Forced (human actions for the purpose of breeding a certain pigeon breed).

The mating period of pigeons depends on the climate in the region. If we talk about our climatic conditions, then crossing occurs in early spring (March-April).

Pigeons tend to show feelings, so the “marriage ritual” will not be long in coming. As soon as the male chooses a female, he will begin to coo with her, circle around her, in every possible way begging for a response. The doves express their consent by bending towards the ground.

When forced mating, great care must be taken important point: before starting this process, it is necessary to separate the residence of males and females for the entire winter period and fully feed the birds with grain containing proteins and carbohydrates (you can add vitamin supplements to strengthen the eggs and bones of the chicks). Pigeons must be at least 1 year old.

There are rare cases where females mate with females. It is difficult to immediately understand what is happening. And only after the doves lay unfertilized eggs, everything becomes clear.

Pigeon nests

Pigeons fight for prepared places; when they build their own nests, there is usually no conflict. If the pigeon breeder himself provides housing for the birds, then places for hatching are needed with reserve. To do this, steam boxes are installed and filled with hay and straw. There must be space between the boxes; this will help pigeon families remember the way to their house (they will choose the box themselves).

The process of hatching and laying eggs

2 weeks after mating, the female lays an egg. This usually happens in the morning. 2 days before oviposition, it becomes inactive and sits in the nest. For young females, the laying process results in great stress, and if the eggs do not come out well, then there is a risk of the dove’s death. The usual clutch is 2 eggs, but young females may have one. The normal weight of an egg is 20 g.

After a week, the shell of the eggs becomes a pale matte color, a little later it acquires a gray tint; when the embryo dies, it is dark blue.

Pigeons take care of their offspring and try to sit in the nest constantly, replacing each other, but they are not so diligent, so it is likely that they can leave the eggs unattended. The female incubates the eggs for about 17 hours, and the male for no more than 12.

Pigeon breeders should keep an eye on the embryos so that they do not become hypothermic, because... this can lead to the death of the embryo or a delay in its development. If it is hot in the pigeons’ home and incubation occurs on hot days, it is necessary to add humidity to the room (spray from a spray bottle).

The incubation period for pigeons is about 19 days. 10 hours before the chick hatches, cracks can be noticed on the shell.

Chicks

Newborn chick weighs 8 - 12 grams, 2 hours after birth he is able to eat. The feeding process occurs when milk is obtained from the parent's crop. Milk contains the required percentage of fat and protein; if the baby pigeon cannot obtain this composition, it will die.

There are cases of lack of parental milk, mainly in young couples. In this case, pigeon breeders resort to the help of nursing birds and feed the chick with grains softened in milk.

Self-feeding chick will be able to in 10 days. During this time, his beak will form; almost the same length as an adult bird.

After 2 months, a healthy chick will weigh the same as its parents.

Steaming pigeons

Many pigeon breeders have noticed that pigeons get used to their partner and their nest, which is why they began to use the term “pairing”.

Fallowing is the artificial selection of birds for the purpose of developing certain characteristics.

These include:

• flight qualities;
• plumage color;
• body shape, etc.

The main task of this process is a successful combination of pairs. If the pairs are chosen correctly, this is, first of all, a step towards the development of healthy offspring, but if the choice turns out to be unsuccessful, the born chicks will be inferior to their parents in development.

By assessing the appearance of newborn chicks, one can draw conclusions about their development and count on mating in the future. In addition to phenotypic qualities, it is also necessary to take into account the pedigree of the birds.

Speaking of inbreeding(closely related mating), then it also has its advantages. It is sometimes very difficult to purchase a pure breed pigeon to inject “fresh blood” into the main core of the farm. You should not give up on inbreeding of pigeons, but, on the contrary, study it in order to use it correctly when mating.
