When the sparrow is frightened, it will increase its internal adrenal hormones, and the increase in this hormone will cause the heart to beat faster, and slowly the toxin will spontaneously form in the body, and the accumulation of toxins will cause the baby sparrow to die on its own.
-
Because the sparrow is very excited when it is caught, it will react physiologically and lead to death.
-
This is because when you catch a sparrow, the sparrow's heart will stop breathing due to the violent beating, which will eventually lead to death.
-
That's because when sparrows die, it's because they can't be free, and they die depressed.
-
Not angry, but because sparrows are unable to move freely and forage.

When I was cleaning the bicycle shed in elementary school, I picked up a hair that didn't grow together, maybe there were too many birds, and it was pushed down, and then I picked it up and put it in the table hole, and fed it rice at noon, and then I took it home, it could be small, but I like people, I like to sleep in your hands when I sleep, and when it's older, you call it, and it flies over, but I didn't pay much attention to the fish raised at home, and when I came back from school one day, I saw it fall into the fish tank and drowned, and it rained that day, I cried and went to bury it with my mother, It's called Chirp, hey, I'm still very impressed......

Because they don't want to be tied down to humans and can't have human smells.
-
When I was a child, it was said that the sparrow had a big temper and could not be raised, and if it was caught, it would die.
-
Sparrows are smart, and when I was in high school, the hot summer sparrows couldn't fly, so I pounced on one, only to find that my eyes were closed and my head was shaking weakly, and my classmates said that I broke my neck. Throw it in the trash.!! Ya flew away!! This high school was laughed at for two and a half years.
-
Because when a sparrow is caught, it goes on a hunger strike and dies.
-
The sparrow is actually really resistant, and if it is caught, it will not live.
-
In fact, sparrows starve to death, and sparrows will not eat what humans feed.
-
Because sparrows are creatures that yearn for freedom and will not be locked up.
-
Species with particularly fast metabolisms are like this!
-
I always thought it was depressed to death. A person who is used to being free and easy, and suddenly he is locked up, and no one can stand it.
-
For social animals, just catch more and raise them together. But the sentence should be enough...
-
Although the sparrow is ordinary, it is not free and would rather die.
-
But I've seen sparrows in their hands.

The sparrow's death after entering the house may be due to the following reasons:
1.The indoor temperature is too high or too low. Sparrows prefer to live in an environment with a moderate temperature. If the indoor temperature is too high or too low, the sparrow's body temperature will be affected, which can lead to death.
2.Eating poisoning. Sparrows prefer to look for food on grasses, leaves, and small plants that cover the ground with more. If a sparrow eats food contaminated with pesticides or chemicals, it is easy to cause poisoning and death.
3.Fear or panic. Sparrows may feel frightened and panicked indoors, especially in an unfamiliar environment, they will be uncomfortable, fearful, and then die.
4.Suffocate. When sparrows enter a closed room, they are prone to suffocation due to lack of oxygen and die.
In summary, there are many possible reasons for the death of sparrows entering the door, and we should try to avoid birds from entering the house. If outside birds are able to get out of the house, we should open doors and windows so that they can escape on their own.
-
The sparrow died as soon as he entered the house, probably because the sparrow's body was hit by the double blow of cold and fright. A sparrow is a wild bird that lives in the wild and is not familiar with the indoor environment, and it may be caused by flying indoors by mistake to chase prey or escape from predators. Once inside, its body temperature drops quickly, as it is usually colder indoors than outside.
If the sparrow does not find a way out in time, it will be unable to maintain normal physiological activities due to hypothermia, and will gradually lose its vitality and eventually die. In addition, its long-term adaptation to the natural environment and food** is also different from the indoor environment, which can also bring additional stress and influence to it.
-
The sparrow you said died as soon as it entered the house, and it was impossible to go through the calendar. If he is trapped in the house and can't get out, he may die.
The sparrow is a small thing that generally can't be domesticated, and it's easy to get angry, and you see that no one can feed the sparrow. If you catch a sparrow and keep it in a birdcage, he will die in a few days.

The symptoms of a sparrow playing dead are:
1.Breathing: Sparrows will stop breathing, making themselves appear to be breathless.
2.Eyes: Sparrows close their eyes tightly and bend their limbs and necks, making their bodies tense and motionless.
3.Movement: To maintain this state, sparrows will clog their bodies tightly with their wings, making themselves appear as a hard, spherical swan, thus deceiving predators.
Playing dead is a way for sparrows to protect themselves and starve, and I hope the above information is helpful to you.

The sparrow pretends to be dead, and when it is no longer dangerous, it will wake up and fly away. Sparrows have a lively personality, bold and easy to approach people, but they are highly vigilant, very curious, and a bit domineering. It sometimes takes over the nest of house swallows!
In the wild, tree cavities are also their favorite nesting spots, especially for old tree groups that know a lot of tree cavities. Sparrows are very smart and alert and have a good memory! Unlike many other small finches, a sparrow will show a closeness to the person who has rescued it if it is rescued by a person, and will wear socks for a long time.

Sparrow Sen Chongqing died suddenly, usually speaking, wild sparrows can't live at all, domestic, sparrows are also difficult to feed, sparrows are very vigilant, birds, if they are caught in the face, the unfamiliar environment adrenaline, will increase sharply, heartbeat faster, blood pressure rises, will show extremely strong, resistance, will choose not to eat or drink to deal with hunting, if there are chicks captured by humans will also find a way to kill, chicks, just to prevent humans from raising chicks, Studies have shown that after just two weeks of captivity, adult sparrows have a decrease of 8% in weight, a decrease in the density of pectoralis muscles, a significant increase in body fat rate, stress, and behavioral changes such as wrinkled feathers.

Cause of death 1: The old, weak, sick and disabled sparrows are easy to die.
There are many times only on the road to pick up the sparrow, take home and raise without success, because this situation is mostly the old, weak, sick and disabled sparrow, in fact, the disease is already sick, or injured, this kind of sparrow itself is very weak, plus the process of people chasing desperately flying, and people with their hands may be very heavy, it is very likely to scratch the organs in the abdomen, so the bird died in the injury, not angry.
Cause of death 2: Death due to poor feeding environment.
There are also many people who catch healthy sparrows, but they can't find a suitable place to raise them, so they put them in some boxes, or buckle them up with some baskets or other things, and the sparrows are in a hurry to return to the original world, so they will fly around in it, causing a rapid decline in physical strength, leading to dehydration, and at that time, even if it is fed, the bird will not eat, and finally die.
Cause of death 3: Hunger to death due to unappetizing food.
There are also many people who catch healthy sparrows in the wild, and there are cages to keep them, but the birds are fed some food that the birds don't know at all (cakes, steamed bun dregs, cooked rice, etc.). The bird had no idea that this food could be eaten, so it starved to death.
Cause of death four: death by strangulation.
This kind of death is the most wrongful, but we have really encountered it. When I was a child, I caught some young sparrows from the sparrow nest in the tree, and the young birds took the initiative to open their mouths to beg for food when they heard the sound of people all day long, and we were often in a good heart, so we stuffed chicken feed or rice and other food into its mouth, but we didn't know that we couldn't control the amount of food, and maybe the food itself was not very digestible, so we often pushed the young sparrows to death.
Cause of death 5: Death due to stress response mechanism.
Animals with protective colors have a strong stress response mechanism, that is, in case of emergency, adrenaline increases dramatically, breathing, heart beat increases, blood pressure increases, and blood flow increases. Sparrows fall into such categories. When they encounter danger, the stress response mechanism allows them to have higher sensitivity and mobility, but if they continue to feel high tension, breathing, rapid heartbeat, and elevated blood pressure after catching the physiological conditions for a long time, the body will produce toxins, which will affect the normal operation of the bird's endocrine and even organs, and eventually lead to death.
Most people don't know how to raise birds, and many people raise sparrows without success, they will tell other people about the "sparrows can't live" this unfounded statement, just as the ancients said - rotten grass for fireflies, this "sparrows can't live" saying slowly spread with people failing.

Why can't sparrows be raised?
-
The sparrow's death is inevitable, but it depends on how it dies, and no one has been able to feed it until now, maybe it's some kind of nature.
-
Sparrows, although known as house sparrows, are actually particularly wild birds.
Adult sparrows are largely not fed by humans, except for newly-hatched chicks, which can be artificially fed.
I'd rather die than give in, this is the character of a sparrow
So, if you're asking why the sparrows you catch can't be raised, that's the reason.
As for the death of sparrows in their natural state, it can be old age, disease, starvation, being bitten to death by other animals, and so on.
There is life and death, this is the law of nature.
-
The cause of the sparrow's death is bird flu.
-
Maybe it's because of indigestion or a germ that causes death.

Forehead.
I think there are many reasons for death. Starvation, freezing to death, exhaustion, life has come. How do you want to die?

There is one animal that I admire, and its name is the sparrow. Sparrows are the most freedom-hungry animals in the world, and almost no one can raise them successfully. After the sparrows were caught, they did not eat the food that came to them, did not endure the disaster of being caged, and died of hunger strike. It is better to die than to be free.
On the surface, the sparrow died stupidly, but in fact, it is the sparrow's philosophy that it is better to live than to die, which has led to the fact that no one has raised the sparrow so far, so that their offspring can benefit and enjoy the free sunshine in the sky forever. We don't see sparrows in prison in any zoo cage. The predecessors believed that "it is better to die than to live", and the descendants must be congenitally deficient to live in the hell of the dire waters.
The predecessors believed that "it is better to die than to live", and the descendants are determined to live in a paradise of freedom and happiness.

It is true that the temper of the sparrow is relatively large, but many people say that the adult wild sparrow will not eat or drink until it is angry once it is caught and raised, which is also reasonable, but there are very few sparrows that are really angry to death.
1。There are many times only on the road to pick up the sparrow, take home and raise without success, because this situation is mostly the old, weak, sick and disabled sparrow, in fact, the disease is already sick, or injured, this kind of sparrow itself is very weak, plus the process of people chasing desperately flying, and people with their hands may be very heavy, it is very likely to scratch the organs in the abdomen, so the bird died in the injury, not angry.
2.There are also many people who catch healthy sparrows, but they can't find a suitable place to raise them, so they put them in some boxes, or buckle them up with some baskets or other things, and the sparrows are in a hurry to return to the original world, so they will fly around in it, causing a rapid decline in physical strength, leading to dehydration, and at that time, even if it is fed, the bird will not eat, and finally die.
3.There are also many people who catch wild healthy sparrows, and there are cages to keep them, but they are fed some food that the birds don't know at all [cakes, steamed bread dregs, cooked rice, etc.] The birds don't know that this food can be eaten, so they are starved to death.
The above three points I mentioned are the practice of most people, because most people do not know how to raise birds, and many people raise sparrows without success, they will tell other people, "sparrows can't live" This unfounded statement, just as the ancients said that ---rotten grass is the truth of fireflies, this kind of sparrow can't raise the saying slowly spread with people's failure.
In fact, wild sparrows are very easy to raise, first of all, you must get a soft cage [such as a cage made of screens] and then put a large open, but relatively shallow container [plates and the like] in the cage [Suzi, hemp seeds, spinach seeds, millet, barnyard seeds, etc.] Then keep the bird's clean drinking water, and then use newspapers to enclose the four walls of the cage so that the bird does not see the outside world, and raise sparrows in this way, with a survival rate of more than 85%.
Other than that. Zhou Yu's small temperament is a matter of romance. It is recorded in the Chronicles of the Three Kingdoms: . . Sex with Zhou Gongjin, such as drinking mellow mash, I don't feel drunk... His energy is very large.
