What are the characteristics of a sparrow? What are the characteristics of sparrows?

1. The body characteristics of sparrows: sparrows are smaller, and the body length of sparrows is generally about 14 cm.

2. The color characteristics of the sparrow: the sparrow's beak is black; tarsal plantar light brown; The head and neck are darker chestnut, and the back is lighter chestnut with black stripes. One of the sparrow's most recognizable features is a large black spot on the left and right of the cheeks, with two white bands on the shoulder feathers.

The tail is small forked and light brown. The throat of the young bird is gray, but it becomes darker and darker as the bird ages, until it becomes black. Young birds are not easily recognizable from males and females, while adults can be distinguished by their shoulder feathers, which are maroon red in this case and olive-brown in females.

3. Characteristics of sparrows' living habits: sparrows are married in groups, except for individual or paired activities during breeding, they are mostly in small groups in other seasons. It is an omnivorous bird that feeds mainly on plant foods and insects.

Sparrows also have the following characteristics:

Strong flight ability, can stay for a short time, can make sharp turns, and fly up and down, left and right freely; Particularly vigilant; Monogamy; Strong reproductive ability, in the season when there are insects, one litter is bred a month, and a nest is at least 4 small sparrows. A litter in the Northeast from June to July to August; The baby sparrows do not build nests in the first year, but build nests to breed in the second year.

Lifespan of a sparrow:

The lifespan of sparrows is relatively short, and the survival rate is not high, and only one of the eight flown chicks can live long enough to pass on to their generations. The oldest sparrow on record lived only eleven years. Sparrows must have nests to survive the winter, and without shelter and food, they can only live for fifteen hours in freezing temperatures.

Strictly speaking, sparrows are the general name of 27 species of birds in the genus Passerinees of the order Ornithischia, because of the similar color and strong vigilance, they will not have close contact with humans, so in the eyes of ordinary people, the appearance is almost the same.

In fact, the more common ones in our country should be house sparrows, tree sparrows, and mountain sparrows.

Sparrows are usually between 10 and 15 centimeters in size, because their intestines are rectal and their stomachs are small, so they cannot store energy for a long time, which leads to the need for frequent foraging, and sparrows fly for a few minutes each time, and they are resident birds who cannot fly for a long time.

Except in winter, sparrows are basically in the breeding period, giving birth to 1 2 litters per year, each nest produces about 6 pieces, and the hatching period is between 12 and 16 days.

As for their lifespan, in a scientific sense, sparrows can live for about 11 years at most, but in terms of big data, the average lifespan of sparrows is between 3 and 6 years.

Why are sparrow carcasses rarely seen?

1.The number of sparrows has decreased dramatically.

After 1958, China's population showed rapid development, resulting in a shortage of food, so a campaign to "eliminate the four evils" was launched.

The sparrow's stealing of grain happened to be seen by the farmers, so the sparrow became one of the "four evils", because the sparrow's heart is very fragile and cannot fly for a long time, so everyone has taken measures such as beating gongs and drums, dismantling birds' nests, waving wooden sticks tied with bright cloth strips, making scarecrows, setting traps, etc., and at night everyone will also hold flashlights to make all kinds of noise.

In addition, at that time, scientists threw out the idea that "for every 1 million sparrows eliminated, we can feed more than 10,000 people", and it was also very good to eat a few meals of bird meat in that era, so in the first year of "eliminating the four pests", the number of sparrows decreased by at least 100 million.

The number of sparrows did decrease, but the subsequent grain production did not rise but declined, because a large number of pests multiplied wildly without sparrows, thus beginning to wreak havoc on crops, resulting in a large number of food productions in various places.

Small body. The upper body is usually brown and black spots.

The sparrow is a small bird with a small body and a complex shape with brown spots on its upper body, so it is commonly known as a sparrow. The small, unformed sparrow has 9 wings and the outer feathers have a light-colored feather edge. The mouth is short and strong, conical, the peak of the mouth is a little curved, and there is no gap between the upper and lower mouths when not speaking.

There is a certain difference in the color of the feathers of male and female birds.

Males are pure hepatic brown from forehead to nape of neck; There are black stripes; There are two distinct white transverse spots on the wings; black chin and throat; Females resemble males, but are light or dark in color with a yellow base of their beak. Sparrows of similar species and other sparrows do not have dark spots on their cheeks. The sparrow is fourteen centimeters long.

Males and females are different in color. The male has a bright yellowish-brown or chestnut crown and upper body, pure black vertical stripes on the upper back, a dark throat, and fair cheeks. Females are dark in color, with dark eye lines and creamy long eyebrow lines.

Sparrows are omnivorous birds, mainly eat the seeds of grasses in summer and autumn, and raise chicks mainly to harm insects of grasses, mostly lepidopteran pests. Due to the mother bird's success in protecting the young, the fertility is extremely strong, and the sparrows are more numerous than many species of birds, and are prone to finch infestation during the harvest time of the crop.

Lively personality, like to live in groups, alert by nature, strong fecundity.

Sparrows are very similar in size and body color. Generally, the upper body is brown and black patchy, so it is commonly known as sparrow. There are 9 primary flight feathers, the pale feathers of the outer feathers (except for the first one) are at the base and proximal ends, slightly enlarged, intertwined, slightly divided into two transverse spots, especially obvious when flying.

The mouth is short, thick and strong, conical in shape, with a slightly curved peak. With the exception of tree sparrows, both males and females are of different colors.

The characteristics of sparrows are as follows:1. Strong flying ability, can stay for a short time, can make sharp turns, and fly up and down, left and right freely.

2. Vigilance is particularly strong.

3. Monogamy.

4. Strong reproductive ability, in the season when there are insects, breed one nest a month, and at least 4 small sparrows in one nest. Northeast.

A litter in 6-7-8 months.

5. The baby sparrows of the year do not build nests, and the nests are built for breeding in the second year.

DistributionSparrows are endemic to the Old World and are native to Africa, Asia and Europe. There are only house sparrows and tree sparrows.

It was taken by humans to places beyond these three continents. But the tree sparrow is not a successful invasive species.

There are very few places where you can successfully establish yourself overseas. Home sparrows have a lot of success, indeed in Oceania.

And many places in North and South America have gained a foothold. But it's also far from everywhere in Australia.

Mainly in the east, while South America is mainly in the south.

The characteristics of sparrows are:

1. Lively personality:

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 in old tree clusters with many tree cavities.

2. Like to live in groups:

Sparrows like to live in groups, especially in autumn, when they form large flocks of hundreds or thousands of individuals, known as finches.

3. Alertness by nature:

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 rescued it if it is rescued by a person, and it will last for a long time.

4. Very united:

Unity is strength, don't look at the sparrows are small, but if there are invaders, they will work together to drive the invaders away. Especially when it comes to brooding, they tend to behave very bravely.

5. Omnivorous birds:

Sparrows are omnivorous birds. Generally, the seeds of grasses are used as food, but in order to enhance nutrition during brooding and propagation, insects that harm grasses will be the main food.

Sparrow's habitat:

The habitat is 300-2500 meters above sea level. Regardless of mountains, plains, hills, grasslands, swamps and farmland, all kinds of forests and shrubs in the low hills and plains at the foot of the mountains, they are mostly active in sparse forests, shrubs and grasses at the edge of the forest, and do not like dense large forests.

They tend to move and forage in places where there are human settlements, towns and villages, river valleys, orchards, rocky grassy slopes, in front of houses and behind houses, and on roadside trees.

Sparrows are extremely lively, vigilant, and curious, mostly active in places inhabited by humans, and live in groups throughout the year. Sparrows are omnivorous birds that feed mainly on grass seeds in summer and autumn, while brooders mainly feed on insects that damage grasses, and also eat crops when they are ripe.

Sparrows are companion birds that inhabit settlements and near fields. During the day, they forage for food, and their range of activity is within kilometers. The wings are short and round, and they are not resistant to flying far.

Feeds mainly on cereals. When the grain is ripe, it mostly flies to the farmland in large groups to prey on the grain. Usually in the granary, yards and residential areas, they tremble and peck at the dried grain or the remains on the ground.

During the breeding period, some insects are eaten, and the insects are used to raise burrows and wide chicks. Strong fecundity. In the north, breeding begins on 3 April, with at least 2 litters per year.

Morphological characteristics

Sparrows are small birds that are very similar in size and body color. Generally, the upper body is brown and black patchy, so it is commonly known as sparrow. There are 9 primary flight feathers, and the pale feathers of the outer flight feathers (except for the first one) are at the base and proximal end, slightly enlarged, intertwined, and slightly divided into two transverse spots, which are especially obvious when flying to the base.

The mouth is short, thick and strong, conical in shape, with a slightly curved peak. There is no gap between the upper and lower mouths when the mouth is closed. There is often a difference in the color of the feathers of male and female birds.
