What month do swallows fly back north? In what month do swallows fly back to the north ?

Swallows return from the south in March-May every yearNorthern RegionsFind a mate, build a nest, and multiply here. From September to October every year, they migrate to the "south" for the winter.

In China, the Qinling Mountains and the Huai River are divided between the north and the south, but the swallows are not only migrating from the Qinling Huai River.

to the south, but to the southern hemisphere of Australia, Africa, South America.

Reasons for the migration of swallows.

Swallows are so adapted to hunting in the air that they are not good at looking for insects in the woods and crevices of the ground, they cannot scratch the ground like chickens and look for insects under the ground; Nor can a sparrow have a long, pointed beak that can catch insects in trees.

Therefore, when winter comes every year, in order to resist the cold winter, insects either die one after another and use eggs to survive the winter; Either they take refuge in walls or soil, and the swallow's food will be greatly reduced. In order to survive, they can only migrate to the warmer south, or even to the southern hemisphere. Only some remain in the tropics.

The swallows may not migrate, because it is warm all year round, and the food ** has no season.

The swallow is a migratory bird that usually returns from the south to the north in March-May each year to find mates, build nests, and breed. At the same time, in September and October, they will move to the south for the winter. However, it is important to note that the time and place of migration of swallows may be affected by factors such as climate, environment, etc., so it may vary.

My family (Hui'an Julong Town, Quanzhou, Fujian) swallows left in early July this year.

Swallows are divided into swifts, floor swallows, house swallows, rock swallows, etc. In China, it began to travel north in February, flying to Guangdong; It arrived in Fujian in early March and was found in Zhejiang and the middle reaches of the lower reaches of the Yangtze River; This phenomenon can be seen in the Yellow River basin at the beginning of April and even before the end of March. Its migratory route is to fly north along the coast and rivers, almost all over northern China, as well as the Republic of Mongolia, northeastern China, and southeastern Siberia.

In addition, when Jiayan traveled north, it first reached Taiwan, then west through the Taiwan Strait to Fujian, or east through the Ryukyu Islands to Japan, and even flew over the East China Sea via Korea to Northeast China, Inner Mongolia, and Siberia. Flying over the high mountains in the middle often faces the danger of being preyed upon by natural predators such as falcons and eagles.

The Swallow flies at a speed of 100-120 kilometers per hour and can basically fly 700-800 kilometers a day. It can be called one of the most flying members of the bird family. The swallows are also very good at flying, some hit the wall like arrows, and some go straight into the sky like arrows; They can make a sudden 180-degree turn, or their wings don't vibrate, they don't shake, and they just glide through the air for a few minutes.

<> Extended Materials. In fact, swallows have a high mortality rate every year on their migratory journey, especially on the days they cross the ocean. Because they need to fly for several days on end, many swallows will fall into the sea and die in the belly of the fish due to weakness or bad weather.

In fact, if swallows lose their mate, they will find another wandering opposite sex as a mate to breed.

If both birds die at the same time, the nest is likely to be abandoned. Because each swallow has different eyes, most swallows will not use the nest built by the same species of swallow How many days does it take for a swallow to fly from its winter habitat to Shandong? If the weather is sunny and windy, it will take about 15 days to fly from the wintering ground to Shandong.

Not necessarily, because the nest is just a place for swallows to breed. Adult swallows do not live inside the nest during the non-breeding period. Swallows are husband and wife birds for many years.

Swallows' nests are usually built on their own.

Swallows return to the north in April and May every spring, and the migration of swallows is mainly related to whether there is enough food, in the north every autumn and winter, insects die in large numbers due to severe cold or burrow into the soil, which causes swallows to find enough food to survive in the north in winter.

Birds such as sparrows, which eat plant seeds, can stay, so in autumn and winter, swallows fly from north to south for a well-fed winter. After winter, the northern insects are all revived and appear in large numbers, and this time is the time for swallows to breed, so swallows will hurry back to the north and build nests and breed in the north from April to May every year to catch insects for survival.

Swallows generally return to the north in the spring, because the grass in the north is full of insects in the spring.

Swallows can generally fly back to the north after Qingming, and there is a saying that one hundred and five swallows fly to Jinan Mansion.

Swallows, which fly back to the north in winter and to the south in spring.

Why not spend the winter in the north?

It's too cold in the north in winter, and there are no worms to eat, so I have to go.

Why go back in the spring?

The climate is suitable in the north in spring, and the rain in the south will wash away the nest, and a large number of insects are active after the sting in the north, and there is a lot of food, and the baby is also guaranteed.

The swallows return to the south around September.

The swallow is a migratory bird that flies from the north to the south in flocks around September before winter arrives, and returns to the north in March when the spring flowers bloom to have children and live and work in peace and contentment.

Swallows are excellent air travelers. In autumn and winter, they come from their native Siberia.

In this area, groups and mighty flew to the south of our country to spend the winter. The following spring, they return to Siberia after a long journey to lay eggs for breeding.

Humid environments tend to trigger a variety of diseases, so the brood room must be spacious, bright, well-lit and well-ventilated. The bedding should be clean, dry and mildew-free, and the utensils should be cleaned, dried and disinfected frequently. The sports field should be cleaned every day to maintain hygiene. It can also be used in feed or drinking water.

Feed garlic juice and penicillin.

etc., which can prevent diseases.

Distribution pattern of swallows

In winter, the food of swallows in temperate regions is greatly reduced, so many species migrate. But unlike most other passerine migratory birds, swallows migrate during the day and fly at low altitudes. In addition, they often forage on their migratory routes, so their fat reserves are lower than those of other migratory birds of the same size.

Species that breed in Africa often migrate in response to rainfall patterns, but little is known about the specifics. Other species, such as the Grey-rumped Swallow, seem to be "wandering" from place to place, with no fixed migration routes.

In recent years, the distribution of many swift species has expanded, as these birds have been introduced to areas previously unknown as they increasingly use buildings as nesting sites. For example, the range of the red-fronted swallow has expanded southward to Kenya and Tanzania.

The cave swallow entered the southern United States from Mexico. Changes in the environment can also lead to changes in distribution patterns. The British population of the House Swallow is in South Africa.

Over the winter, their range there has now expanded westwards due to increased rainfall in the west.

<> wild goose flies south in the moon, in the spring of the next year, the wild goose flies north in the month, and the little swallow flies to the south in the month;

Xiaoyan flew from the south to the north in the moon.

Extended information: The southward flight of geese is actually a migratory bird migration. Even in the north, the winter is too cold for the geese to survive on their own, so they need to migrate in large groups to reach the south before winter and spend the winter in the south;

On the contrary, when it is too hot in the south, the geese need to go back to the relatively cool places in the north to read the hot summer.
