The birds that migrate during the Antarctic and Antarctic times are:

Arctic swallow yard. In summer, the Arctic tern.

They breed in the Arctic, and in winter they fly to the Antarctic to spend the winter, where they enjoy the Southern Hemisphere summer. When winter arrives in the Southern Hemisphere, they fly to the North Pole to enjoy the summer there.

The bird that migrates between the North and South Poles is the Arctic Tern, which migrates between the North and South Poles and flies up to 40,000 kilometers per year. The Arctic Tern has a body length of about 35 cm, a wingspan of about 75-85 cm, and a weight of about 80-120 grams. Their tails are forked and their wings are narrow and long.

Such a light body is very conducive to flight, and such wings allow them to be much more buoyant than other birds when flying in the air.

Arctic terns travel between the North and South Poles once a year, and their average lifespan is about 30 years old, which means that they can fly at least 2.4 million kilometers in their lifetime, and the farthest distance from the Moon to the Earth is only 400,000 kilometers, which is equivalent to the distance that an Arctic Tern flies in a lifetime, and can circle the Earth at least 3 times.

Arctic tern migration routes.

Arctic terns will begin to migrate every August, for example, the Arctic terns that inhabit the Glenland, will first stay in the northern Azores for a month, hunting, accumulating their physical strength, and then begin to fly south in September, migrating along the continental shelf, food resources are relatively abundant, generally from western Africa or eastern South America to the south.

1.Birds that migrate with the seasons are called migratory birds.

2.Migratory birds are birds that migrate periodically with different seasons. Many birds migrate seasonally along latitudes, breeding in temperate regions at higher latitudes in the summer and wintering in the lower tropics.

In late summer and early autumn, these birds migrate south from their breeding grounds to their winter grounds, and from their winter grounds north to their breeding grounds in spring. These birds, which migrate north and south with the changing seasons, are called migratory birds.

3.Birds that migrate with the seasons are called migratory birds. Migratory birds travel from the south to the north, and when they pass through a certain place, they are called traveling birds.

For example, swallows travel from Guangdong to Hebei. When passing through Anhui or Huguang, it is called a traveling bird. For the division of birds, different properties can be divided into different species.

Migratory birds are called migratory birds.

4.Migratory birds represent the change of seasons and migration for survival and livelihood.

Which birds are migratory? What are the migratory birds?

Some birds can change habitat at regular intervals with the change of seasons in one year, and these birds are called migratory birds.

Migratory birds can be divided into two types: summer migratory birds and winter migratory birds.

The former refers to flying to a certain area in spring and summer to nest and settle down, give birth to children, when the young birds grow up, it is late autumn, they fly to the warmer areas in the south to winter, and fly to this area to breed in the spring of the following year, for this area, this kind of bird is called summer migratory birds. Such as Jiayan, etc., spread throughout all provinces and cities in China in summer, and migrate to southern Yunnan, Hainan Island, Xisha Islands and Taiwan in winter; For example, cuckoos and orioles are also summer migratory birds.

The latter refers to wintering in a certain area in winter, flying to the north to breed in the spring of the following year, and when the young birds grow up, it is late autumn, and then fly to the original area to winter, for this area, this kind of bird is called winter migratory birds. For example, wild geese, swans, wild ducks, etc. are winter migratory birds in the middle and lower reaches of the Yangtze River in China. Most migratory birds have the habit of migrating from north to south, and the farthest can cross the ocean, such as the peregrine falcon, which can reach Australia directly from Siberia via China.

In addition, there are very few migratory birds that can fly from west to east or vice versa.

Geese generally have migratory habits.

Examples of migratory birds: wild geese, swans, mallards, cuckoos, orioles, black-tailed gulls, wild geese, bean geese, mallards, shelducks, spot-billed ducks, and so on.

Movies about migratory birds, you can't miss "Migratory Birds", also known as "Dreams and Birds Flying", by the famous French director Jacques Anderson

Hello dear! The birds that migrate during the Arctic and Antarctic times are the Arctic terns. The animal is found in the Arctic and nearby areas of Xiaoli Ye, and breeds near the Arctic in the Arctic, Europe, Asia and North America.

The Arctic Tern has a longer tail and a more monotonous beak than the Gulf Tern, while the Red Tern has a darker body and longer wings.

The birds that migrate during the Arctic and Antarctic times are the Arctic terns. They are found in and around the Arctic and breed near the Arctic in the Arctic, Europe, Asia and North America. Compared to the common tern, the Arctic Tern has a longer tail and a more monotonous beak color, while the Red Tern has a slightly darker body color and longer wings.

Physical characteristics: Arctic terns are medium-sized birds. The body length is 36 cm, the wingspan is 76-85 cm, and the weight is 80-120 grams.

It is characterized by a "black hood" on the top of the head, black on the nape of the neck and the top of the head, gray and white feathers, white on the forehead, black on the top of the head and nape of the neck, white on the cheeks, black on the back of the ears, pure white on the neck, brown shoulder feathers, gray on the back of the upper body with white feathers, and a forked tail with gray feathers. The wings are pale gray in color, and near the tips of the wings are pale to nearly colorless. The tail is white and the belly is pale gray.

pinnae white, with broad white margin on the inside; Gradually smaller from the outside to the inside. The first primary feather is black on the outside. Secondary flight feathers grey, inner and pinnae white.

The iris is black, the beak is red, and the feet are red.

Habits: Inhabit swamps, coasts and other areas. During the breeding season, it mainly inhabits the coast, island rocks and sandy and gravel grounds, and during the non-breeding period, it mainly inhabits the open ocean.

It's the Arctic tern. It is a species of seabird belonging to the genus Tern. Medium in size, body length 33-39 cm, wingspan 76-85 cm.

Its plumage is mainly gray and white, its beak and feet are red, its forehead is white, the top of its head and nape of the neck are black, and its cheeks are white. Its gray wings are 305 mm and its shoulder feathers are brown.

Bird migrations are usually twice a year, in spring and autumn each year. Birds migrate from wintering grounds to nesting grounds in spring and from nesting grounds to wintering grounds in autumn, and migrate regularly and regularly over long distances between breeding areas and wintering areas along relatively fixed routes. The results of the current study suggest that many birds migrate seasonally.

Migration brings many benefits to birds, mainly in the following ways:

1. Make birds always live in the most suitable climate, and have a rich variety of food**, which is conducive to maintaining their strong metabolism;

2. Migration can also create the most suitable conditions for raising offspring, because raising offspring requires a lot of food;

3. In the north, the largest number of eggs can be hatched, the season is long, there are abundant insects, and the parent birds can have the opportunity to fully collect food;

4. There are fewer predators in the north, and the appearance of this annual fragile young black will not promote the formation of predator populations

5. Migration can greatly expand the activity space, which is conducive to reproduction and the behavior of competing for occupied areas

6. It is conducive to automatic balancing and can make the bird off avoid climate disparity

7. Migration provides opportunities for bird populations to spread to new distribution areas and for contact and mating between different individuals, so the spine sedan chair is also of great significance in evolution.
