In the countryside, you can see the bird s nest in the trees with the openings facing upwards, aren

Because the ecological environment in the countryside is relatively good, there are a lot of birds living in the countryside, and if there are birds, there will naturally be bird nests. However, we can find that most of the bird nests on the trees in the countryside are facing upwards at the beginning, and the birds are not afraid of rain when they build their nests like this? What is the purpose of nesting like this?

Let's take a look:

1. Convenient feeding: I believe everyone has seen the scene of bird feeding, which is sent by the old bird to the young bird mouth-to-mouth, and the young bird only needs to open its mouth and stick out of the nest. If the nest does not open upwards, it will be difficult for all the young birds in the nest to stick their heads out, and it is not only troublesome for the mother bird to feed, but also easy to skip feeding.

2. Convenient to escape: the opening is facing upwards, and when encountering natural enemies, you can directly spread your wings and fly from the nest, which is convenient for escape. If the nest still has a roof, it is more troublesome to take off, and once you take a slow step, you may fall into the mouth of a natural enemy and become food.

3. It is related to the terrain: we can clearly find that most of the nests built on the branches of trees are open upwards. This is because the branches grow upwards, and when birds make nests, there is a fixed nest position on the bottom surface, but there is no place to fix it, so naturally there is no way to make a nest.

In fact, there is no need to worry too much about this, birds can be said to be natural architects, when birds build their nests, they do not simply start upward, but bend inward at the edge of the opening, so that they can build a roof for the nest and shelter from the rain when it rains. In addition, most of the birds' feathers have a layer of grease on them, and the rain falls directly on their bodies, making it difficult to wet them, so they are not particularly afraid of rain.

That's all for the above explanation, I hope it will be helpful to you. I wish you a happy life and all the best. Remember to like and**Oh, pay more attention with your rich little hands!

Bird's nests with openings upwards can meet these needs to the greatest extent, and building on tall branches can also prevent eggs from being stolen, as for the problem of being drenched in the rain, in fact, don't worry, most bird's nests with openings upwards will take into account the problem of location, and buildings are preferred in places where the foliage is dense and rainproof.

Don't be afraid, when the bird is building a nest, it can ensure the breathability of the bird's nest, which is convenient for the bird to land and avoid the rain, so it is not afraid of rain.

These birds are not afraid of rain, because there are many branches in the nest, and the bird's feathers are very hydrophobic, so they are not afraid of rain at all.

Most birds build nests not to create a home for themselves, but only to meet the needs of reproduction. These birds, who do not keep their nests at home, often rely on their powerful feathers to provide shelter from the wind and rain when heavy rains come. Because they have the ability to face wind and rain, this is also biological evolution.

The corollary.

Birds need to maintain a constant and high temperature during the hatching process, and newly hatched birds need to be kept warm without feathers. Therefore, the baby bird needs a warm home during the hatching and growth stage, so the adult bird builds a nest. The shape of the bird's nest is often a round nest with an opening upward, which has many benefits, first of all, it can meet the survival needs of the bird during hatching and growth, and at the same time, the bird's nest opening upwards can ensure that the bird will not fall off, and it is also convenient for the adult bird to fly in and out to find food to feed the bird.

However, the nest with the opening upwards is not waterproof, which requires the hard-working adult bird to use its body to shelter from the wind and rain when it rains.

When birds encounter heavy rain, there are generally two ways to take shelter from the rain, one is to take shelter from the rain under the eaves or in the dense woods, such as sparrows. But most of them are in the rain, and the bird's fear of being caught in the rain has a lot to do with its feather structure. There are two types of feathers: feathers and down, and the thick feathers on the outside have a strong waterproof function.

When it rains heavily, birds generally do not fly, but stand there with their wings closed, and most of the rain runs down their wings. Even if some rainwater wells go under the feathers, it will encounter down. But the down underneath the feathers is better for insulation and waterproofing.

The bird also has a classic water-shaking action that shakes off most of the water. All of these characteristics ensure that the birds are safe and sound in the water.

For birds, nesting is hard, but it is also a need to hatch the next generation. When faced with heavy rain, they either choose to take shelter from the rain or rely on their own ability to face the heavy rain head-on.

Birds build nests to let themselves have a resting place, the most important thing is to hatch birds in it, they generally choose to build a nest in the corner of the house, so as to effectively avoid heavy rain.

Birds build nests to reproduce, and when it rains, they take shelter from the eaves of their roofs.

<> reason why the bird puts its nest on the tree:

1. Bird nesting is an important part of the success of bird breeding, the nesting location varies from species to species, and the nest is built on a tree, which can increase the concealment of the nest;

2. The choice of nest site by birds is closely related to the lifestyle of each bird and the place where it feeds, for example, forest birds build their nests in the canopy of trees to forage for food;

3. Birds build their nests in trees, and their IQ is conducive to avoiding the predators and reproduction.

The birds are brilliant architects who have carefully designed their new homes. The Bird's Nest in China was inspired by the Bird's Nest. How remarkable, all human beings have to learn from them!

There's a reason why bird's nests are generally upward! A bird's nest is a place where birds roost, mainly for reproduction and the growth of young birds. If the nest is facing down, the egg will fall easily.

It is especially dangerous for young birds. It's so active, and if you're not careful, you'll fall off. With the beak facing up, there is a more spacious area for the birds to play.

Consider the difficulty of the architectural design. The nest is definitely going down or around, it is more difficult to build a nest, and it is much simpler for the nest to climb up. Most nests are made up of twigs and thatch, which are piled up and slowly woven into the shape of oysters.

It's simple to do this because of the gravity of the earth, and the gravity of the nest facing upwards is also better and stronger! Can it rain in the nest of a bird's nest. Don't worry about that.

Birds don't have to worry about rain. Because that nest is in a tree with a lot of leaves. Even if it rains, it falls in the nest because there is not much rain.

Another point is that the bird's feathers are waterproof and will not get wet in heavy rains. Because there is a layer of oil on the surface of the feathers of the nest, rainwater will automatically slide when it falls on it. As for the birds, you don't have to worry anymore.

When it rains, the mother bird will fly away early. Weather can be allowed. Then spread its wings, wrap the little bird underneath, and use its wings to shield the cub from the wind and rain.

In this way, the nest climbs upwards, and the nest with the mouth open is generally the nest of large birds. Nests for large birds are generally made from branches, trunks, or hay. Nests made of branches and stems generally do not make their beaks too small, and if the nest mouth is small, it will be difficult to get in and out of the body of a large bird.

So the large nest will make the nest bigger, facing up, and the bird's father, bird, and mother will take care of the young. Generally speaking, the birds that build such nests belong to the birds that move frequently and do not stay for long. This bird is relatively free when nesting.

In addition, they will also look for places that can block the wind and rain or be found by predators in a more stealthy way, such as dense trees, between bushes, abandoned houses, caves, etc.

Usually birds do not choose the rainy season when breeding and nesting. Because not only is it difficult to find females to mate during the rainy season, but it is also difficult for well-built nests to survive the long-term cleaning of the rain. And, if it's windy, there's a good chance that the nests of these birds will lose their cover due to strong winds, making them easy to spot by predators.

Fathers and stepmothers take turns foraging for food in order to protect young newborn babies while the birds breed. So when it's windy and rainy, the birds spend their time under the shelter of a new dad or new mom. Adult birds have feathers that withstand wind and rain and cold, so they are not prone to illness even when it rains.

The first is security. For birds, the nest is a habitat for birds, which is mainly used for breeding and breeding and for the growth of young birds. If the head of the nest is facing down, the eggs are easy to fall, especially for young birds, which are very dangerous, they love to move, and they will fall if they are not careful.

With the opening facing upwards, there is a more spacious area for the young birds to play.

Secondly, the difficulty of construction design is considered. Obviously, if the head of the nest is facing down or facing around, it is more difficult to build a nest, while the head of the nest is much easier to build up. Most of the nests are made of branches and thatch, and they just need to pile them together and slowly weave them into the shape of a nest head, which is very simple.

And due to the gravitational pull of the earth, the head-up bearing force is also better and more stable!

Again, about whether the head of the bird's nest will be exposed to rain. In fact, there is no need to worry about this, the bird does not have to worry about rain, because the nest it builds is on some trees with dense leaves, so even if it rains, it will not rain much if it falls into the bird's nest. And there is another point, that is, the bird's feathers are waterproof and will not get wet in heavy rain.

This is because the feathers of the nest have a layer of grease on the surface, and rainwater drops will automatically slide down when they fall on it. As for the birds, there is no need to worry, when it is going to rain, the mother bird will fly back in advance, they are able to ** the weather, and then they will spread their wings to protect the bird underneath, and use its wings to shelter the young birds from the wind and rain.

Most animals, including birds, are not fools and will build their nests in safe and comfortable places, where the wind and rain are neither suitable for shelter nor for breeding. From this, we can see that the condition of the bird's nest in the tree is only an appearance, and it is not actually raining as we thought.

For those small birds, when they choose to build their nests, they will generally choose a leeward place with relatively dense foliage or tree poles to block the rain. While it's not possible to block out the rain 100 percent of the time, they can pick up a large part of the rain in their chosen places.

There is a certain natural law about the bird's nest on the village tree, which is a certain natural law, and the bird is also a bird's nest established by applying the laws of nature, which has a certain scientific nature, and is not a bird's nest built indiscriminately. Why are the bird's nests in the trees facing upwards and not afraid of the rain?

First, the mouth of the bird's nest is facing upwards, and the birds are of course afraid of rain and sun. However, the best birds choose to make a nest will also be comprehensively considered, not only to facilitate the nest, but also in a relatively leafy position. With dense foliage, it is definitely better to shelter from the wind and rain and the sun, and it also plays a role in shading the bird's nest.

2. Where the nest is facing upwards, the function of the nest is to give birth to children. Once the birds can fly, they abandon their nests, even if it is windy, rainy and snowy, they will not stay in the nest. In addition, the nest is facing upwards, and when breeding small birds, it basically avoids the cold winter.

In spring, summer and autumn, small birds cannot be frozen, and even if it rains, big birds will cover their nests with their bodies. Not in winter, because there are many nests with the nest mouth facing up, the base is also very simple, a few dense branches can lay eggs and breed birds, and the cold air will freeze the birds from the bottom. If you look closely, you can see that there will be no birds living in the bird's nest in the cold winter when the mouth of the nest is facing up.

3. Nature is also fair to all things by natural selection. Humans have natural disasters, and so do birds. Although the nest mouth is facing upward, although the childcare period avoids the cold winter, but it cannot avoid the hail and strong winds of summer.

Due to the hail, the mother bird will defend the bird and be crushed to death by the hail; Due to the strong winds, some small birds and eggs will fall from the nest and die.

Fourth, some bird's nests are very exquisite, which can not only shelter from the wind and rain, but also keep warm from the cold. For example, the common magpie nest in the countryside has a special prominent entrance and exit, and some magpie nests are divided into two layers, and the bottom of the nest has mud and flocculent solidification to form a warm blanket, which is complete like a human villa mansion. Bird's nests like magpie nests are really home to people, and the nest is their home.

All year round, they are inseparable from the nest, and one nest can be used for several years.

5. Some birds are not born to nest, and some of them use natural burrows; Some are in the grass in the air, among the gravel, on the sand; There are applications to human buildings, and so on. They can also survive and are part of the laws of nature.

In short, the bird's nest seen on the trees in the countryside is basically facing upward, but there is also a part that is not facing upward, but looking at the nearby buildings to build my bird's nest, and some birds are built very exquisitely. Especially for small birds, the nest is the strongest and safest, and it is particularly beautiful.

Because it is constructed with two small ends and a large middle, it forms a honeycomb-like shape, and when it rains, the birds will put their heads on the edge of the nest, so that the rain will hit the hair on their tails.
