When do sparrows generally breed 5

Sparrows breed in the north every year from March to April. During mating, there is a "marriage scene" behavior, when the male bird appears to be particularly active, and often uses a low, weak call, while raising his head and tail, looking around, standing restlessly, and also causing other males in the group to participate. It was particularly noisy for the birds; Sometimes, when the cry is being aroused, it often suddenly quiets down and flies away a few, or all of them, scattering the parties.

This completes the pairing process. The nest is made by both male and female birds, about 5 to 6 days, and then begins to lay eggs, which are laid between the early morning; One egg is laid every day, sometimes with an interval of one day. During the egg-laying period, the parent birds do not enter the nest overnight.

The number of eggs per clutch is generally 4 6, the minimum is 3, the rare 2 eggs (Xining), the maximum number is 8, and the most common is 5. The color of the eggs varies greatly, some are light brown, some are white and blue, and all are mixed with regular gray-blue, yellow-brown and purple-brown coarse spots, and the blunt ends of the eggs are particularly dense; The eggs are oval-shaped; Weight, the size of the egg is 15 pieces on average.

The hatching period of sparrows is 10 to 12 days, and it is also recorded to be 12 to 14 days. The nestling period is 10-15 days. The hatching time is mostly around 8 o'clock in the morning, the nestlings that have just hatched are bare and featherless, ** red with yellow, the eyes are not opened, this is only about about the weight of the egg, lighter than the weight of the egg; 4 5 days after the eyes are opened, the feather area is basically formed, and the feather sheaths of primary and secondary flight feathers and small wing feathers are born; The average weight is 19g, which is the highest weight in the chick stage, and it can be identified as a sparrow chick from its appearance; days, the weight drops, equivalent to the weight of the day, but the body length is increasing day by day, until it tends to stabilize, at this time the body length has reached 110mm, the body surface has developed and shaped, some chicks begin to leave the nest, some fly out of the nest one day apart, after the chicks fly out of the nest, the same night is different to enter the nest overnight.

The number of times sparrows breed each year varies according to the different climates in the north and south of China. A maximum of 3 reproductions have been recorded in Hebei Province, 4 times in Guangzhou, and 2 (or 3 times) in Jilin Province (the first litter is hatched in late May, and the second litter is hatched in July). The Tibetan Plateau is only 1 2 times.

In the north, breeding begins on 3 April, with at least 2 litters per year. In the south, sparrows can be seen breeding chicks almost every month. The nests are simple, composed of grass stems, feathers, etc., and are mostly built under the eaves and in the holes in the walls.

Each clutch lays 4 6 eggs. The eggs are grayish-white with brown spots. Males and females take turns incubating their eggs.

Incubation period 11-12 days.

The breeding period of sparrows is 5 to 6 months, and by the end of the month the birds have come out of the nest

The southern ones have already nested, and they're about to lay eggs, and the northern ones are about half a month late.

Sparrows can breed 2-3 litters a year.

Sparrows are one of the common small birds, and their breeding season is usually in spring and summer. Sparrows have strong reproductive habits, can lay eggs 2-3 times a year, each nest can lay 2-8 eggs, the incubation period is about 12-14 days, young birds need to continue to protect and feed for about 2-4 weeks after the nest is cracked. Therefore, if there is no external interference or other unexpected circumstances, sparrows can breed 2-3 litters a year, and the total number of eggs or young birds is relatively stable.

Although sparrows are more reproductive, in recent years, due to environmental pollution, habitat loss and food shortages, the number of sparrows in some areas is declining. In order to protect this precious natural resource, it is necessary to strengthen the protection of bird habitats and dietary environments, and avoid the threat and harm caused by human activities to bird breeding. At the same time, it is also necessary to reasonably treat and use wild bird resources such as sparrows, abide by relevant laws and regulations, and put an end to illegal hunting, ** and other behaviors.

The specific flowering time of the sparrow.

Rice grass grows mostly in warm and humid climates, and is shade tolerant and drought tolerant but not cold-tolerant. Strong and fast by nature, with strong climbing ability. The flowering period is from early March to mid-April, and the months of cold weather or heavy rain are delayed by about half a month.

From 010 to 1010, when the spine blooms, its petals will roll into a wing shape, and the whole flower will be delicate and transparent. Because of its "head, eyes, mouth, withered wings, and tail", it looks like a cluster of small sparrows, which makes tourists linger and take pictures. The flowers are light green or creamy white when they bloom, lemon yellow when they bloom, and then pink or orange-red.

Usually there are 10-20 flowers per bouquet, and many can grow to 20-30 flowers. There are hundreds of flowers on one tree, which is very spectacular.

Sparrow flower cuttings propagation: The method of skewer number cuttings is used to propagate sparrow flowers. First of all, the shoots chosen as cuttings must be strong enough. We also need to formulate a solution containing rooting hormones such as rooting powder, and immerse the selected shoots in the solution to promote the rapid rooting of cuttings.

After that, we can insert the branches into the wet sand bed. At this time, it is necessary to pay attention to shade and keep the soil moist at all times. It takes about a month to take root.

The method of propagation by cuttings is generally carried out in the spring, so that the cuttings are easier to germinate. When taking cuttings in summer, be sure to pay attention to sun protection and moisturizing.

Strip propagation of grass sparrows.

What is needed for layered reproduction is the vines of the sparrow. The lower end of the vine internodes was scratched and then buried in the soil. At this time, the soil should be kept moist.

After the buried vines grow roots, Xiao Kaixian can cut the vines from the original plant and then they can be cultivated. We can fertilize properly to promote the growth of new plants.

Sowing and propagation of grass sparrows.

Sparrows can also be sown for breeding. The flowers will bear fruit in the fall, and then we can get 5-10 seeds from the fruit. When we sow and reproduce, we should choose full seeds with short storage years and seeds with strong vitality.

Before sowing, we need to soak the seeds in water to allow the sparrow's seeds to absorb water and swell, generally 7-10 days. After the seeds swell to a certain extent, they are placed in a dark and damp place, and when the seeds grow true leaves, they can be transplanted into the soil and planted, which can grow to about 1 meter in a year.

1. When to start practicing flying

Sparrows are a common small bird that is very capable of flying, but young birds cannot fly for a few days after birth. In general, sparrow pups begin to practice flying around the 10th to 15th day after birth. This is because during this period, their wings have grown some feathers that support their bodies.

To practice flying, young birds jump onto branches, vibrate their wings and try to fly. This process may continue for several weeks until the chicks' ability to fly is fully developed.

2. How to learn to fly

The process for a sparrow chick to learn to fly is a long one. As they practice flying, they will keep testing and eventually find their balance and flying skills.

During the flight practice, the young birds will also jump on the ground and try to test fly. This process may seem dangerous, but for young birds, it is the process of learning flying skills.

In the process of learning to fly, young birds generally continue to improve and perfect their flying skills according to their own experience and the guidance of their parents. Parents also play an important guiding role in their practice.

3. How to tell if a young bird is already able to fly

Whether sparrow chicks are able to fly or not depends mainly on their level of maturity. When the wings of the young birds have developed to a certain extent, they can try to fly.

In general, sparrow pups start flying around the 10th to 15th day after birth. If a baby bird is already able to vibrate its wings and try to fly in the air, then the baby bird has mastered some basic flying skills.

In addition, young birds also need to have the corresponding speed and flight altitude during flight. When a young bird can fly independently, and can master a certain flight altitude and speed, it can be judged that it has mastered basic flying skills.

4. Some measures can help young birds learn to fly

First of all, you can provide a safe and comfortable environment for the sparrows. In a safe environment, young birds can practice and learn to fly more freely.

You can also prepare some food for your young birds so they don't have to worry too much about their diet. At the same time, you can also accompany the young birds and instruct them on what to look out for during the flight.

Sparrows are mostly active in places where there are human beings, and they are extremely lively, bold and approachable, but they are very vigilant and curious. Nest in human houses, such as eaves and wall holes, sometimes occupy the nests of house swallows, and in the wild, nest in tree holes. They can sometimes be found nesting in individual trees, but sparrows are found in flocks during the four seasons of the year, and old trees with many holes are often their favorite nesting spots.
