Birds and mammals have long since "diverged" in evolutionary history, so what birds call "poisonous insects" for mammals is not necessarily poisonous insects. This may be one of the reasons why birds are fine when they eat poisonous insects.
In addition, the intestinal tract and liver of birds can easily denature these protein toxins, thus making them less toxic. Therefore, even if birds ingest poisonous bugs, these protein toxins can be inactivated during digestion.
In addition, for some birds, such as hawks, they may excrete toxins from their bodies after preying on poisonous bugs. The eagle's droppings do contain some toxic substances, which suggests that they can process these toxins to some extent.
Overall, the bird's physiology and ability to handle toxins keep them safe when eating poisonous insects. However, for some poisonous insects contaminated with heavy metals, birds may be affected. In this case, we need to take steps to reduce the impact of pollution on wildlife such as birds.

Some are because its stomach can be digested, just like a person is fine if he eats chocolate, but a dog will be poisoned if he eats chocolate. Some venoms only work when they see blood. If a poisonous snake bites its prey to death and eats it, it will not be poisoned.
-
The structure of the body of a bird is different from that of a human, and most of it will be excreted after eating it.
-
Legend has it that chickens have crowns and can eat poisonous insects. I remember that the flower spider I caught when I was a child fed the birds, and the birds were sticks one day. . . It's okay to eat chickens, and the big roosters I raised when I was a child even ate small snakes and geckos...
-
There is something that people don't see when they eat, roasted spiders, centipedes, and scorpions are also eaten by many people. You won't be poisoned if you eat it raw, but you won't be poisoned if you are bitten. Chickens can also be poisoned if they are bitten.
-
Because chickens don't have the same digestive system as we humans.

In order to survive and supplement nutrients, birds can grow and reproduce normally. Therefore, they are born and their parents start to feed insects in order to grow and develop, mainly because insects contain a lot of nutrients to provide them with normal growth and development.
1. Insects are very rich in nutrients, including organic substances: proteins, fats, carbohydrates, etc., as well as a large number of free amino acids and vitamins required by the human body; Inorganic substances: various salts, potassium, sodium, phosphorus, iron; Calcium, etc.
According to analysis, per 100 ml of human plasma, it contains 24 4-34 4 mg of free amino acids, and every 100 ml of insect blood contains up to 293 mg of free amino acids, which is several times higher than human blood.
2. In addition to eating insects, birds also eat some grass plants to supplement the lack of vitamins and minerals, eating plants can supplement the deficiency of trace elements in the body, which is beneficial to their health.
-
Because birds have to eat, for example, we have to eat, and if birds don't eat, they will starve to death, and the same goes for people.
-
It's nature; Almost all small birds eat insects, and their main food is insects, otherwise insects will flood if they have no natural enemies, and crops will not survive;
As for those bugs, no matter what kind of bugs and birds they eat, it's just that different birds eat different bugs.
-
Insects are delicious, just like people like to eat meat, which is better than vegetables.
-
Hehe, people have to eat, and it will be hungry if it doesn't eat, and if it has a choice, I'm sure it will like to eat too, haha
-
Don't worry at all, the centipede's toxins don't work until they pass through the bloodstream, as long as the bird's throat is not wounded, it's fine.
-
No, the reason is that chickens love to eat centipedes, and nothing is wrong with it.
-
Centipedes can be eaten! The problem is that it likes to eat.
-
It is better not to eat centipedes that are poisonous.
-
Who's to say it won't? The life of a parasite is likely to be spent in different organisms, some as intermediate hosts and some as final hosts. For example, some parasites will live in the eye stalk of a snail, and then be eaten by birds, lay eggs in the intestines of birds, and be excreted with feces, and snails will be infected with parasites after eating feces.
-
Small birds eat the adults and larvae of ordinary moths. Some field pests of Coleoptera (praying mantises, locusts, crickets), larvae of some beetles (mealworms).
-
Sparrows like to eat noctuidae, corn borer, cotton bollworm, cabbage worm, etc. Turtle doves also eat wheat, millet, grass seeds and cabbage worms, corn borer, mountain magpie: scarab ground tiger, green worm, noctuidae locust.
-
Bugs, complete the expansion sentence: If the early bird does not eat the bug, the bug will be eaten by other birds.
-
1 No, the pigeon does not like to eat insects, ostriches, pelicans, albatrosses, ......There are many birds that don't eat insects!
-
No, there are different species of birds, each species has different predatory habits, some feed on plant seeds, some feed on young leaves, some eat insects, but some are omnivorous.
-
Birds almost all eat insects, especially in their juveniles. Some birds are mainly insects, such as hoopoes and chickadees, some birds are mainly plant fruits or stems and leaves, such as pheasants, some are omnivorous, and they will eat whatever they encounter, such as magpies and sparrows, but they will not refuse insects This gourmet meal, especially during the brooding period, it is difficult to breed young birds in a short period of time without insects, and young birds are the most vulnerable stage, this stage is of course the shorter the better. About 95 percent of the world's birds feed on insects to some degree, such as woodpeckers.
Some birds that don't usually eat insects will catch insects and feed their offspring when they breed their offspring.
-
The gastrointestinal function of birds is underdeveloped and needs to be spleen and appetizing, just like children.
-
1 time the worm is not the other worm.
2. The insect has a strong desire to survive.
3 times the bird is not the other bird.
The bird has a cuticle on its feet, which is very dry and has very poor conductivity, it can be considered that it is not conductive, and it does not care about the resistance of the high-voltage line or something, and there is also the problem of parallel circuits, the bird does not conduct electricity at all, does not form a potential difference, and cannot reach the loop, so there will be no current through, of course the bird will be fine, understand?
I have 3 points for your reference: The reason why you are bored and have nothing to do is because the surrounding environment is too cumbersome, the things around you are too cumbersome, so it seems to have been integrated, when you are alone and withdrawn, you will feel a kind of emptiness that has no form to compare, In fact, there is no need to repeat every day asking what to do; Or what to do, when you don't know anything, don't think about anything, don't do anything, you can get through boredom by simply sleeping in a daze. Don't think so much, you're born boring, so if you keep repeating boring things, you'll feel bored, and think differently. >>>More
The answer is simple, because a bird has wings, and it can fly. >>>More
1. The body of birds is streamlined, the body surface is covered with feathers, the forelimbs become wings, the bones are light, thin and strong, the chest muscles are developed, and there are air sacs to assist lung breathing. >>>More
