When do swallows usually start hatching their calves?

Swallows generally start hatching their calves in April-July.

Swallows hatch for 10-14 days, and only during the breeding season they lay eggs, not at other times.

Male and female swallows take turns to hatch for about 1 month, and the newly hatched birds have feathers, can move around, and eat completely independently until 15-20 days later.

Swallows generally start painting in May and June, small swallows. Because the weather is too cold, it will not be able to bless the little swallows, and the swallows will freeze to death. So they all started painting little swallows when Lao Hu was in time.

Swallows begin to build nests in March and migrate from mid-October to late November depending on the regional temperature. House swallows nest under the eaves of the farmhouse, the nest is made of mud and grass stems with saliva bonding, and the inside is covered with fine soft weeds, feathers, rags, etc., and there are some Artemisia annua leaves, and the nest is dish-shaped.

2 litters are bred each year, mostly from May to early June and mid-June to early July. Each clutch lays 4 6 eggs. The second litter is less and less at 2 5 pieces.

Milky white eggs. Male and female co-incubate eggs. 14 15 days old birds out of the shell, the parent birds are fed together.

The chicks fly out for about 20 days, and after feeding for another 5 to 6 days, they can feed themselves. The food is all insects.

Summary. Hello dear! Glad to answer for you, how long does it take for a baby swallow to become a swallow, my dear, for you to answer as follows:

The young swallow will definitely need to grow into a swallow for a full length of one hundred and ten to one hundred and twenty days. Dear, 5-8 months after hatching, develops into an adult bird. In addition to the change in wax film face, the sign of changing from a young bird to an adult bird can also be seen from the change in the horizontal stripes on the forehead of the young bird, which has the horizontal stripes of heise.

Dear, the chicks fly out about 20 days after hatching, and then feed for another 5 to 6 days, and then they can take their own food. Hope it helps, my dear! <>

Have a great day! <>

Good luck! Move your precious finger and give a 5-star thumbs up! Thank you. <>

There are four seasons, in the south there are all year round, and in the north there are only spring and summer, because swallows are migratory birds and are afraid of the cold.

When I was a child, I learned the song of Little Swallow.

Little swallow, dressed in flowers.

Come here every spring.

I asked the swallow why you came.

Swallow said:"Spring is at its most beautiful here"

Little Swallow, tell you.

This year it's even more beautiful here.

We built a big factory.

Installed with a new machine.

You are welcome to stay here for a long time.

Swallow is a collective name for 74 species of birds in the passerine swallow family.

The swallow is small, with narrow wing tips, concave tail and short beak, weak feet, and not too many feathers.

The swallow's wings are long and good at flying, and the beak is short and weak, and the beak is wide, which is the beak shape of a typical insectivorous bird.

The swallow is a passerine swallow family with a small body size of 13 to 18 cm.

The swallow's plumage is blue-black, shiny, with a black-brown chest and a milky white belly; The wings are pointed and long, and the tail is forked like open scissors.

The swallow's beak is flat and short, and its mouth is deeply clefted; The flight speed is fast, and it preys on mosquitoes, flies, locusts and other pests during the flight; and constantly emitting a short, sharp chirp.

The swallow has long wings and a forked tail. Most of the back feathers are gray-blue-black, so it was called Xuanniao in ancient times.

Swallow is a beneficial bird for human beings, mainly mosquitoes, flies and other insects as the staple food, a swallow can prey on more than 500,000 pests in a summer, protecting crops.

Swallows hatch their eggs together. 14 15 days old birds out of the shell, the parent birds are fed together. The chicks fly out for about 20 days, and after feeding for another 5 to 6 days, they can feed themselves. The food is all insects.

All swallow species almost exclusively feed on aerial invertebrates, mainly insects. Plant-based foods are found in only a few types of foods and are consumed in small amounts. Only the bicolor tree swallow regularly ingests plant matter (mainly berries), and this is only guessed to be during periods of insect scarcity.

Swallows are not opportunistic foragers, and they don't fly around aimlessly, eating random planktonic spike creatures in the air with their mouths open. Instead, they take the initiative to hunt specific prey.

Swallows generally fly away in autumn, mostly around September. This is because swallows in the northern hemisphere are mostly migratory birds, which arrive in the south in the spring to breed and leave the south in the fall to return to the north for wintering. Swallows breed in the south because the temperature is more suitable and provides enough food and habitat, while in the north the temperature starts to cool down in the fall, they need to travel south to find more suitable temperatures and resources.

It is important to note that the migration of swallows is carried out according to changes in climate and light conditions. When the days are long and the nights are short, the temperature is low, and food is scarce, the swallows will start to migrate to warmer, sunny places in the south in search of better living conditions. During the migration, swallows need to fly thousands of kilometers and go through a long journey, which is also a test of their physical strength and endurance.

In addition to the time of migration, swallows also have unique habits and ecological requirements in terms of breeding, perching, foraging, etc. The breeding season of swallows is in the spring, and they like to build nests in high places, such as cliffs, buildings, etc., which provide convenience for flying and foraging. As a result, swallows can often be seen nesting under the eaves of buildings, which has also become one of the interesting sights of swallows co-existing with humans.

In short, the swallows fly away in the autumn of Kuanwei, and the time of migration is carried out according to the changes in climate and light conditions, and the survival habits and ecological environment of the swallows also need our attention and protection. <>

Every spring in 4-5 months.

Swallows spend a lot of time catching pests in the air and are one of the most flexible passerine species, mainly feeding on mosquitoes, flies and other insects, and are well-known beneficial birds. Nest in tree holes or crevices, or drill holes in sandy banks, or stick mud on walls or protrusions in corridors, roofs, eaves, etc. in urban and rural areas. 3 7 eggs per lay.

The elongated body reduces drag during flight. The wings of the swallow have a high aspect ratio, which means that it can generate a lot of lifting force with little resistance. However, this aerodynamic efficiency comes at the cost of reduced maneuverability (e.g. compared to short, wide wings), but this disadvantage is partially compensated for by the forked tail, which improves the bird's maneuverability.
