How can birds find their nests correctly

Scientists have explored many aspects of the phenomenon of bird navigation orientation, and have made a lot of observations and researches

Using the Earth's magnetic field to identify directions: Many scientists believe that some birds rely on the Earth's magnetic field for directional navigation. Pigeon navigation is a prime example.

Every point on the earth has its own geomagnetic field, and organisms have adapted to this physical environment in the process of long-term evolution, and the carrier pigeon has flown home accurately with the special ability to feel the strength of the earth's magnetic field.

Navigating by the sun and stars: At the beginning of the 20th century, a hypothesis was proposed that birds rely on the sun for directions, and the German ornithologist Dr. Kramer devised a scheme to test this theory. He noticed that when the migratory season came, the caged birds would jump around in panic.

At this point, he put several birds in cages into a circular pavilion with a skylight to record the position of each bird. He found that they often headed in the direction they were supposed to migrate. When the windows are closed, the birds lose their orientation and are flying around.

Later, he installed a "light fake sun" to make the artificial sun rise and fall at the wrong time and direction. As a result, the bird in the pavilion flew in the wrong direction towards the artificial sun.

Birds can also use the stars to determine their direction: one of the more popular theories is that birds' migratory habits and ability to discern their paths are innate, which can only be explained by genetics. Scientists have experimented with storks.

There are two species of storks living in Germany, one in the west and the other in the east, and they migrate to Egypt during certain seasons. But the migration routes of the two species of storks are not the same. The stork, which lives in the west, flew over France and Spain, then across the Strait of Gibraltar and along the coast of North Africa to Egypt.

The storks in the east bypass the end of the Mediterranean Sea to Egypt. Scientists transplanted the eggs of the eastern storks into the nests of the western stork, and after hatching, they were marked to make them easy to identify. Amazingly, when the eastern birds grow up and migrate, they do not fly with their adoptive mothers, but follow the routes of their ancestors.

In the study of the secret orienteering of birds, it has also been found that in addition to the response to the Earth's magnetic field, the use of the sun and stars, and their own genetic factors, the infrared sensitivity of birds, their sense of smell and echolocation systems may also play a role in orientation.

The turn of spring and summer and the turn of summer and autumn are the two seasons of thrush breeding. At this time, after going up the mountain, first use a thrush whistle or a "matchmaker" bird to tease the old relatives of the wild thrushes on the edge of the mountain or beside the woods, and then walk in the direction of the old relatives birds. When you walk near the old parent bird, you will find that the old parent bird has to feed the chicks.

At this time, observe the direction in which the old parent bird flies, and follow the old parent bird until the nest is found.

Once the nest is found, see how big the chicks have grown. If the chicks are still very young, or even just a few days after the eggshells have emerged, they cannot touch or take them, and they will change their names to pick them up when they grow up. Because some thrushes are very angry, they find that someone has touched their calves, and they do not continue to feed the chicks.

If the nestlings are already relatively large or even about to put the nest, you can take out one or two of the nestlings back to feed, and leave one or two for the old relatives to feed, and never "even the nest end". You know, it's also a way to protect wild thrushes. If it is "even the nest", the old parent bird may be angry to death, or it may flee to other places, and there may be no thrush on this mountain in the future.

Therefore, on this issue, we must also "take it in the right way" and not look at the present without regard for the long term.

You must know that the "nest finch" cannot eat by itself, and must rely on artificial feeding for a period of time, and then depending on its situation, it will be fed with water and pecked by itself. Otherwise, it will die from fasting.

In addition, birds are also very particular about the location of their nests, and usually these birds will be related to their own lifestyle and feeding location when choosing the address. For example, in the forest, many birds will build their nests in the canopy of trees, some will build directly in the bushes or grass, and some will even hide their nests in tree holes.

Birds use tree branches, or various weeds, as well as plant fibers to build their nests, and will choose the corresponding burrows or areas in advance. Bird couples build nests together, or with branches, or alone, with the corresponding soil, or by the lake.

Birds build their nests by choosing a good place and the right season, with the right building materials. There are mainly object nesting methods, hanging nesting methods. Cave nesting method, ground nesting method. Tree branch nesting methods.

Birds are the use of branches and leaves rich in plant fibers, mixed with their own feathers or animal hair, to play the role of thermal insulation and reinforcement, generally nest between two branches, when building a nest will first pick up some larger thick branches to build a frame, and then with feathers and small branches to fill, and finally use their own saliva to reinforce.

They build in the right places, and they also pay attention to the food and light. Some birds grow out of mud, some build their nests with branches, and some pick up some feathers. Some birds also use wood chips.

One. What is Birdie? Two.

Nest. Three. Why do small birds build nests?

The main reason why birds want to build a nest is because they can build a house of their own by nestingThen live in it and rest quietly. Especially for the birds that are about to reproduce, nesting is a thing that must be completed, only in this way can they reproduce in a safe and comfortable nest, which is relatively safe. Therefore, in our lives, we often see nests built with branches or feathers at the top of some branches, or the top of houses, and these nests are usually relatively small in area, but they look very delicate.

Each bird builds a nest in a different way.

Like all ungulates, it is in the nature of animals to stand soon after birth. The same goes for birds to build nests, it's instinct, and every bird is born with the idea of how to make its own nest. Many small birds use twigs and grass to form cup-shapes, such as cardinals and thrushes.

Some swallows build their nests with mud balls, which they attach to cliffs or under eaves.

Some birds, such as the little, build their nests in tree cavities or caves, and they use grass, feathers, fur, and moss to build on the bottom of the burrows. Some birds use petioles to build complex "apartment-like" nests, which can be up to 3 metres tall and can accommodate 100 or more birds at a time.

Different birds have different ways of building nests, and birds will take some small wood and stick it together with their saliva to build a nest, and birds are good friends of humans.

The bird actually latched on to the ground with various branches, and then went to build a nest on a tall tree, and would also use some grass to make its own warm nest.

When it comes to nesting, this is a technical job, a big project, for small birds, the birds usually fly to the distance to pick up some small branches and hay to build its nest, little by little accumulation.

A bird's nest. "個" is the most widely used quantifier, mainly used for nouns without special quantifiers, and some nouns can also use "individual" in addition to dedicated quantifiers. A person, two pears, three bells, a teapot, a one, a mouth, a handle, and a pound, kilogram, bucket, liter, ruler, inch, zhang, etc., which represent weights and measures, are all different types of quantitative units used to represent people or things.

A person, two pears, three bells, a teapot, a one, a mouth, a handle, and a pound, kilogram, bucket, liter, ruler, inch, zhang, etc., which represent weights and measures, are all different types of quantitative units used to represent people or things.

A proper noun quantifier is used to indicate the unit of measurement of a thing. For example, "strips, roots, branches, zhang, grains, grains, individuals, doubles, pairs, buckets, kilograms, kilometers, acres" and so on. The above examples are all special measure words.

Some noun quantifiers are borrowed from nouns, such as "jar (a jar of water), saucer (a plate of peanuts), box (a box of books)", etc., this kind of quantifier is called "borrowed quantifier".

Take the cuckoo, for example.

The cuckoo never builds a nest, but puts its eggs in another nest and asks the nest owner to hatch it for them. The cuckoo lays its eggs on the ground, and then goes to the vicinity of the willow and shrike nests to peep at the movement. If it sees the owner of the nest leave, it jumps up, puts its own egg in its mouth, and then takes the owner's egg from the nest.

The movements are quick and neat, and it can be completed in less than 1 minute. It takes stolen eggs to secluded places as a delicious meal. After the nest owner flew back, he found no abnormality and continued to incubate the eggs.

The cuckoo generally lays 3 6 eggs, its eggs develop faster than other birds' eggs, about 13 days or so, the baby cuckoo will drill out of the eggshell, and then push the eggs of the nest owner out of the nest. In this way, the little cuckoo can enjoy the upbringing of "righteous parents" exclusively. The little cuckoo has to eat a lot of insects every day, and its "righteous parents" are busy feeding it all day long, that is, they don't know that their biological children are killed by the little cuckoo, and it is hard to feed a "**".

The righteous relatives finally fed the little cuckoo until the feathers were full, and when they could fly, this little thing without plot left the poor righteous relatives and walked away.

At the beginning of the magpie's nesting, the magpie first piled up the bottom of the nest on the key points of the 3 tree oaks, and when it was spread to a considerable area, it stood along the fence and built the fence along the perimeter, and later went to the fence to support the beams to further seal the top of the nest.

Magpie camp nest, often lasted a long time, from the beginning of the branch to the initial completion of the shape of the nest to take more than two months, plus the internal works are all over, it takes about 4 months left beam wide front right. The outer branches of the magpie's nest appear to be very rough, but in fact its entire structure is very complex and delicate. From the outside, the whole magpie's nest is an upright ovate, with a large height of 80 cm and a horizontal circumference diameter of 60 cm, making it difficult for one person to hug it.

There is a round hole on the side of the nest, the caliber is just suitable for the magpie to enter and exit, the top of the nest is very thick, up to 30 cm, the branches are densely arranged, and the showers fall, and they do not leak for a long time. Inside, a thumb-thick willow beam is visible underneath, which is a sturdy support for the roof of the nest. Magpies are able to erect beams on top of their nests to protect them from wind and rain.

The magpie's nest is mainly composed of dead branches, which looks like a bunch of branches from a distance, but in fact it is more delicate, almost spherical, with a top cover, the outer layer is dry branches, mixed with weeds and soil, the inner layer is thin branches and soil, and the inner cushion is soft substances such as hemp, fiber, grass roots, moss, animal hair and feathers.

If you want to find a nest, try the following tips: Observe the behavior of the birds: When nesting, birds will choose places that are more hidden and fierce, such as branches, tree holes, grass, etc., so you can observe the behavior of birds and find places where they may nest.

Look for birds' flight routes: Birds often choose places that are closer to their food** when nesting, so look for birds' flight routes to find places where they might nest. With the help of a telescope:

If you want to find the nest more accurately, you can use a telescope to observe the bird's behavior and nesting location. Pay attention to the calls of birds: Some birds make specific calls when they build their nests, so it is possible to pay attention to the calls of birds and find places where they may be nesting.

Respect the living habits of birds: When looking for a bird's nest, be sure to respect the living habits of birds, do not interfere with their lives, and avoid causing harm to birds. It should be noted that after finding the nest, it is also necessary to respect the living habits of the birds, and do not interfere with their lives to avoid causing harm to the birds.

If you are looking for a bird's nest, here are some tips that may be useful:1Decide which bird species you are looking for:

Different species of birds choose different types of habitats, so first determine what kind of bird you're looking for. In this way, it is possible to better understand their ecological positive characteristics and habitat requirements, and to find nests in a targeted manner. 2.

Choose the right season: During the bird breeding season, it is easier for birds to nest in specific habitats. Therefore, choosing the right season to look for can increase the probability of success.

3.Finding a habitat: According to the ecological characteristics and habitat requirements of the birds, look for suitable places such as trees, bushes, grasses, etc., and carefully observe whether there are signs of bird nests.

4.Pay attention to observation: When looking for a bird's nest, carefully observe the surroundings and pay attention to whether there are signs of alteration in branches, leaves, grass, etc., or whether there are birds flying around.

If there is, it may mean that there is a bird's nest nearby. 5.Be quiet and patient :

When looking for a bird's nest, be quiet and don't disturb the birds. At the same time, it is important to be rent-resistant, as it is sometimes necessary to wait a while before discovering the location of the nest. In conclusion, finding a bird's nest requires some observation and search skills, as well as a certain amount of patience and time.
