What impact do baby sparrows have on our lives?

Sparrows have both good and bad effects for humans. Sparrows are omnivorous birds, mainly feed on the seeds of grasses in summer and autumn, and brooding mainly feed on insects that damage grasses, most of which are lepidopteran pests. Due to the successful protection of young birds by parent birds and the high fecundity, sparrows are more numerous than many species of birds, which makes them more likely to form finch infestation during the harvest season.

In winter and early spring, sparrows feed on weed seeds and seeds of wild grasses, as well as a variety of foods discarded by humans.

Looking forward to seeing helpful answers!

Sparrows are common resident birds in most parts of the country, preferring to live around human living areas and use the crevices of buildings as nesting sites. One of the more interesting characteristics of sparrows is that they cannot walk on their feet, but can only jump, that is, they move one by one. I used to read a folk tale about this phenomenon, saying that because the sparrow likes to steal food, it actually broke ground on Tai Sui's head and stole the food of the king Lao Tzu, but was shackled by God, so he could only jump.

Speaking of which, sparrows do have a bad fate. Because they often eat grain in groups during the grain harvest season, after the founding of the People's Republic of China, for a considerable period of time, our country listed sparrows as one of the four pests and was wanted by the whole country. In the cities and villages, gongs and drums were beaten everywhere to prevent the sparrows from falling to the ground, so that many sparrows were so tired that they fell to the ground and died.

Although the sparrow is no longer one of the four pests, due to the improvement of people's living standards in recent years, civil buildings across the country have undergone great changes, and the nesting sites that sparrows can choose are becoming fewer and fewer, and the number of sparrows has gathered and declined in some places. Of course, the reasons may be more complex, but this phenomenon also provides a good animal model for studying conservation ecology.

Sparrows are the most common small birds. They often inhabit the crevices of woods and buildings, have no migratory habits, and are resident birds. Birds are generally able to walk on the ground on their hind legs, but sparrows do not have the ability to walk on flat ground, and only rely on their legs together to make rapid and frequent jumps.

It turns out that the limbs of the sparrow are short, consisting of the thighs, shins, tarsus and toes, and the entire hindlimb muscles are distributed in the thighs and shins, and the other parts are all tendons. These tendons run through the toes and control the curvature of the toes, allowing the sparrow to hold on to the branches. However, there is no articular between the tibial tarsal and the phalanges of the tarsal part of the hind limbs of the sparrow, so the joints between the tibia and the tarsal bone cannot be flexed, which makes the sparrow unable to walk on flat ground, but can only jump quickly and frequently.

Bold: Sparrows have a lively personality, bold and easy to approach people, but they are highly vigilant. Social Living:

Sparrows like to live in groups, especially in autumn, when they form large flocks of hundreds or thousands of individuals, known as finches. Smart: The sparrow is very smart and alert, has a good memory, and will show a closeness to those who have rescued it.

Unity: Sparrows may be small, but if there is an intruder, they will work together to drive the intruder away. <

4. Unity: Although the sparrows are small, if there is an intruder, they will work together to drive the intruder away.

5. Feeding habits: Sparrows are omnivorous birds, generally feed on the seeds of grasses, and insects that harm grasses will be used to strengthen nutrition when breeding.

The living habits of sparrows are generally to eat and make things.
